The Rafale is poised to become Europe's premier fighter-bomber
by Michal Fiszer
Jun. 6, 2005
France's Rafale is the most capable aircraft of the three new-generation fighters developed in
Europe over the last two decades. Although the Dassault Rafale, Eurofighter Typhoon, and Saab
Gripen are all currently being developed as multirole aircraft, only in the case of the first were strike
capabilities made a priority from the very beginning of the program. The remaining two were initially
optimized for air-to-air missions, with attack capabilities added later. When current conflicts demand
mainly air-to-ground capabilities, the Rafale (the name means "squall") better fits those
requirements, being a true strike fighter by its very nature, and it is not any worse in air combat
than its two European competitors. Various circumstances dictated that that Rafale would be fully
multirole, while the Gripen and Typhoon are fighters with strike capabilities. Dassault goes even
farther and calls its aircraft "omni-role," which means that Rafale can perform ground-attack
and air-combat tasks in one sortie
The requirement for stealth led to redesigning the fuselage, which produced Rafale's
characteristic shape. The radar-absorbent materials initially used caused the dark color of the
Rafale C prototype (shown here), but later special electromagnetic-transparent paints were
developed so the aircraft could receive any color scheme.
This is not to say that the Rafale's superiority as a European air-combat platform is absolute. There are
many factors that weigh against the aircraft, chiefly complexity and cost. Moreover, not every nation
has the same requirements for its air arm, and there are many qualities to recommend the Typhoon and
Gripen, not to mention comparable candidates from Russia and the US. To date, no foreign customer
for the Rafale has been found, while Saab already has three export customers for Gripen – the Czech
Republic, Hungary, and South Africa – and even Eurofighter has found an export sale outside of its
consortium membership – as of now, though, only to Austria. One could ask why such a capable and
technically successful aircraft as the Rafale has had such a difficult road. Perhaps the Rafale is
"over qualified," and potential customers, including France, do not wish to pay for capabilities
that they do not need.
Nevertheless, as we shall see, a combination of good planning and good fortune has conspired to place
the Rafale at the forefront of European tactical aircraft.
Early Development
Initial studies for an Avion de Combat Tactique (ACT; Tactical Combat Aircraft) started at the French
Ministry of Aviation as early as in 1975. At this early stage, the aircraft was to be a prospective
supplement to the Mirage 2000, which first flew in 1978. The Mirage 2000 was to be a light fighter in
the F-16 class, optimized for air defense and related tasks, while the ACT was to be a heavier and more
capable aircraft, optimized for ground attack, reconnaissance, and air superiority. Among the authors of
these early requirements, called ACT 92 (1992 was the year of expected service entry), was LtCol
Vincent Lanata, later Chief of Staff of the French Air Force.
Initial studies for an Avion de Combat Tactique (ACT; Tactical Combat Aircraft) started at the
French Ministry of Aviation as early as 1975. Early efforts to cooperate with the Anglo-German
effort that would lead to Eurofighter did not pan out, and the French pursued the ACT on their
own. The French had a requirement for a multirole aircraft, and the Rafale's unique "omni-role"
nature is a function of this. Pictured here is the Rafale B.
The UK and Germany initiated an international consortium to develop a future multirole aircraft in
1977. It was even agreed that the aircraft would be a two-engine, single-seat multirole fighter with a
delta wing and front horizontal control surfaces (canards). The aerodynamic layout was actually
proposed by France, which joined the consortium. However, due to conflicting requirements,
cooperation ended in the spring of 1981. Germany wanted to build an air-defense and air-superiority
fighter; the UK wanted to build a heavy multirole aircraft with an emphasis on air-to-air missions;
while France wanted a lighter multirole fighter with the emphasis on air-to-ground missions. Finally,
the common development effort split into the French ACT 92 and the German-British European
Combat Fighter (ECF), resulting from the British Air Staff Target (AST) 403 and German Taktisches
Kampfflugzeug (TKF) 90 requirements. The ECF finally evolved into the four-nation (with Italy and
Spain) Eurofighter Typhoon, and France decided to proceed with ACT 92 on its own.
On Oct. 30, 1978, Avions Marcel Dassault-Breguet (presently Dassault Aviation, Paris, France)
received an initial contract for the development of the ACT 92 project, supplemented on December 20
by a contract for its naval version. In 1979, more serious studies about possible configurations of the
new aircraft were undertaken by the Office National d'Études de Recherches Aéronautiques (ONERA;
the National Office for Aviation Studies and Research). The project was conducted under the codename
Rapace – bird of prey. In March 1980, Dassault-Breguet started studying four aerodynamic
configurations, all with canards and delta wings. Two had a single vertical tail fin, while the others had
double vertical fins.
Ten of the first production batch of F1-standard aircraft built were Rafale M naval single-seat
fighters, eight of which equip the 12F Squadron (shown here), replacing obsolete Vought F-8E
(FN) Crusader fighters. Total requirements of the French Navy call for 60 aircraft (all single-seat
Rafale Ms), and the French Air Force ultimately is to procure 95 Rafale C single-seat and 140
Rafale B two-seat fighters.
In October 1982, Charles Hernu, the French minister of defense, announced that Dassault-Breguet
would build a technology demonstrator called the Avion de Combat Epérimental (ACX; Experimental
Combat Aircraft), based on the ACT 92 study. On April 13, 1983, it was decided that the ACX would
be built according to the project prepared at Dassault Technical Department and headed by Bruno
Revellin-Falcoz. The design team was led by Jean-Jacques Samin and Claude Hironde. The Dassault-
Breguet proposal was prepared in close cooperation with ONERA, the Ministry of the Air Force, and
the Délégation Générale pour l’Armement (DGA; France's top military-procurement authority). In
September 1984, the French government, acknowledging that other countries' requirements were too far
apart from French operational needs, decided to build a combat version of the ACX with the newly
designed Snecma M88 engines. The proposal totally eliminated any hope that France cold be lured back
into the ECF program, since those specifications were not acceptable to Germany and the UK.
The new aircraft was named the Rafale by Dassault, and the ACX technology demonstrator became
Rafale A. Among the requirements for the new aircraft, three elements were especially
interesting: the decision to design the aircraft with the use of available stealth technologies, while
keeping the accepted aerodynamic lay-out, including radar-absorbing materials (RAMs), shaping
of some features (such as the fuselage, inlets, etc.), and extensive use of composite materials; the
decision to equip the aircraft with a glass cockpit and employ a hands-on throttle and stick
(HOTAS) and fly-by-wire controls; and the decision to integrate all of the avionics, navigation,
fire-control, and self-protection equipment into a single system controlled by a central mission
computer.
The requirement for stealth led to redesigning the fuselage, which produced the Rafale's present
characteristic shape. A single air intake was split into two side-mounted intakes that were carefully
shaped to prevent an enemy's radar from observing Rafale from the front hemisphere by getting returns
off the moving parts of compressors. The vertical fin was made of electromagnetic (EM)-
transparent composites. The RAMs initially used caused the black color of the Rafale C
prototype, but special EM-transparent paints were later developed so the aircraft could receive
any color scheme. All of those undertakings dramatically reduced the radar cross-section (RCS)
of the Rafale, especially from the front. It is very difficult to assess the Rafale's RCS due to the high
level of classification, but sources have unofficially said that Rafale has a much lower RCS than the
Typhoon, a fighter of roughly the same size.
Initially, a more stealthy version of Rafale was to be developed. It was named Rafale D (D for "discret,"
or stealth) and was to be built in land-based and naval versions. But it was later decided that the serial
Rafale would be of reduced overall size and that, with the end of the Cold War, such high levels of
stealthiness would not be required.
In the spring of 2002, 12F Squadron became operational, and with seven Rafales, it deployed
aboard the aircraft carrier Charles de Gaulle (shown here), which went to the Indian Ocean in
support of Operation Enduring Freedom. While the Rafales were not combat ready, they did
engage in mock air combat with US Navy F-14 and F/A-18 fighters. By all accounts, the Rafales
put in an impressive performance. In March 2004, Charles de Gaulle again set off to the Indian
Ocean, where her embarked Rafale squadron took part in the Northwind 2004 joint exercises
with Mirage 2000-9s of the UAE. Later, the aircraft took part in the Varuna exercise conducted
with the Indian Navy, and Rafales were matched against Indian Sea Harrier FRS.51s. Another
exercise, Red Shark, conducted with Saudi Arabia, enabled Rafales to conduct practice
engagements against Saudi Tornado F3s.
Building of the Rafale A technology demonstrator started at Dassault's Saint-Cloud factory in March
1984, before a contract with the DGA was signed. It was temporarily powered by General Electric
F404-GE-400 engines (68.8 kN of reheated thrust each). The first flight took place at Istres on July 4,
1986. Four years later, the aircraft was re-engined with Snecma M88-2 engines with 72.9 kN of thrust
each. The Rafale A was used for tests until 1994.
Progress in electronics enabled a reduction in the size of the Rafale's airframe. This resulted in an even
lower RCS. It is also worth emphasizing that the smaller and lighter airframe used in production
Rafales enables them to fly in "supercruise" mode – supersonic flight without the use of
afterburners. Supercruise enables the aircraft to execute a part of the ingress and/or egress route
at supersonic speed without serious penalty to its tactical radius.
Rafales of the F2 standard can carry an assortment of precision-guided weapons, including laserguided
bombs (shown here, on a Rafale B), Apache stand-off missiles, and SCALP cruise missiles.
Future enhancements will enable Rafale to carry anti-ship missiles and other strike weapons,
including the nuclear-armed ASMP-A missile.
Four such redesigned pre-production aircraft were built: a Rafale C single-seater for Air Force, a Rafale
M single seater for the Navy, a Rafale B two-seater for the Air Force, and a Rafale M two-seater for
Navy. They were first flown on May 19, 1991; Dec. 12, 1991; April 30, 1993; and Nov. 8, 1993,
respectively. The Rafale B was the first aircraft to receive the newly developed Thomson-CSF and
Dassault Electronique (now merged into Thales) Radar à Bayalage Electronoique Deux Plans (RBE2;
Radar With Two-Axis Electronic Scan), the Spectra self-protection system, and the final version of the
F1 standard avionics and navigation system. The use of the two-seater made tests of the aircraft's
electronics systems easier. (Note that the designation Rafale M for the pre-production two-seater is
confusing, because the designation Rafale N had been reserved for such aircraft.)
All Rafale production versions are incrementally divided into four standards, called F1, F2, F3, and F4
in France, and also referred as Block 01, Block 5, Block 10, and Block 15 for export purposes. All of
the land-based Rafales have 14 hardpoints for external weapons. The naval Rafale M has thirteen
hardpoints due to the reinforcement of the fuselage structure for carrier operations, so it has one central
fuselage station instead of two in tandem. The F1 can carry up to 10 MICA EM and Magic-2 air-to-air
missiles (6+4, or 5+4 in the naval version). Interestingly, F1 aircraft do no carry MICA IR missiles. The
central fuselage stations are intended for MICA missiles, while the rear station can accept a drop tank.
Four additional stations are mounted on the fuselage sides – the rear pair for MICA missiles and the left
front for the Damocles targeting pod (used in F2 and above aircraft). Six additional stations under the
wings can be used for two drop tanks and four MICA missiles. The outer stations and wingtip stations
can be used only for Magic-2 infrared-guided short-range missiles.
The Rafale is equipped with a single 30mm GIAT 791B cannon mounted on the right engine duct. The
gun has a rate of fire of 2,500 rounds per minute, and the fighter carries 125 rounds of ammunition.
Sensors and Electronics
The RBE2 radar had been in development since 1989. It was decided that the radar would receive a
new phased-array antenna with full electronic scan, instead of the electro-mechanical scan employed by
the Eurofighter Typhoon's Captor radar. Initially, the radar received a passive phased-array
antenna, but ultimately an active electronically scanned array (AESA) will be fitted. According to
French Ministry of Defense (MoD) sources, the RBE2 radar has a modest range about 100 km
against fighter aircraft, but it operates in a low-probability-of-intercept (LPI) mode and is
resistant to deception jamming. The Typhoon's Captor has a range of 160 km against fighters
but is considered more prone to jamming and can track fewer targets. The French Air Force
accepted the penalty in range reduction for the benefits of LPI and other characteristics.
Moreover, in network-centric operations, a common air picture will be transmitted via the
Multifunctional Information Distribution System (MIDS) to the Rafale, enabling the aircraft to make
use of off-board sensors.
According to Thales, the radar operates in the X band and can use low, medium, and high pulserepetition
frequencies. It can track up to 40 air targets in track-while-scan mode and, according
to an unofficial source, can engage up to eight of them with missiles launched in short intervals.
Normally up to six (five on the naval Rafale M) MBDA (Paris, France) MICA EM missiles can be
carried. An unusual feature of the infrared-seeking MICA IR version is that the missile can receive
mid-course update commands from the radar to compare the target location with the location of its
seeker's track or for lock-after-launch engagements. The effective range of both the infrared- and radarhoming
missile versions, therefore, reaches 70 km. Electronic beam steering enables the RBE2
radar to search the airspace in various patterns, probably up to 60 degrees in any direction from
the fixed antenna axis. The radar enables not only track while scan but also so-called "track here while
scan there." For example, the RBE2 can readily track airborne targets while searching for another
airborne target in another sector. The radar performs automatic prioritization of threat targets and has
the ability to discriminate a single aircraft in a group in raid-assessment mode. The F1 standard radar
has no air-to-ground functions.
The Rafale's RBE2 radar has a modest range of about 100 km against fighter aircraft, but it
operates in a low-probability-of-intercept (LPI) mode and is resistant to deception jamming. The
French Air Force accepted the penalty in range reduction for the benefits of LPI and other
characteristics. Moreover, in network-centric operations, a common air picture will be
transmitted via the Multifunctional Information Distribution System (MIDS) to the Rafale,
enabling the aircraft to make use of off-board sensors. This Rafale B carries an assortment of
MICA EM (inboard) and Magic-2 (outboard) air-to-air missiles.
The AESA radar is not being incorporated into the F3 standard. The development of the AESA
version of the RBE2 radar started officially in April 2002, when the DGA awarded Thales a
contract for development of an active-array radar demonstrator optimized for the Rafale. Called
the Démonstrateur Radar à Antenne Active (DRAA; Active Array Radar Demonstrator), the program
culminated in a series of demanding flight tests to validate the system's detection performance. In
December 2002, the first flight of the AESA system was carried out in a Mystere XX flying testbed
belonging to the French MoD and located at the Flight Test Center at Cazaux. Subsequently, the DRAA
was fitted to the two-seat production Rafale B301, which flew with it for the first time in May 2003.
The next step is now the Démonstrateur Radar à Antenne Active Modes Avancés (DRAAMA;
Advanced Modes Active Array Radar Demonstrator) program, which was officially launched by the
DGA in July 2004. The DRAAMA will be entirely new and will benefit from the latest
developments in radar and solid-state technology. It is possible that the AESA radar will be
introduced with the F4 standard and/or will form an upgrade package for earlier aircraft.
The Spectra [Système de Protection et d'Evitement des Conduites de Tir du Rafale] self-protection suite
has been integrated by Thales, but it consists of elements built by various companies. The Spectra
consists of a radar-warning receiver (RWR), missile-launch-warning system (MLWS), laserwarning
receivers (LWS), a management computer, four chaff/flare dispensers, and a built-in
jammer, all integrated into a single automatic system. The RWR and active jamming system were
developed by Dassault Electronique (presently Thales) and are integrated as the Détection et
Brouillage Electromagnétique (DBEM) system. According to an unofficial source, in the F1
standard, the DBEM can detect transmitters over the frequency range of 2-18 GHz, but this was
increased to 2-40 GHz on the F2 standard. The system has a very high accuracy of up to one
degree in azimuth. The DBEM automatically detects, classifies, and identifies emitters and inputs
information about them into the computer. The Spectra's active jamming subsystem uses phasedarray
antennas located at the roots of the canards. Reportedly, the antennas can produce a pencil
beam compatible with the accuracy of the receiver system, concentrating power on the threat
while minimizing the chances of detection. It also uses other low-probability-of-detection
techniques, so the Rafale's electronic-countermeasures (ECM) capability is also compatible with
its stealth requirements. The MLWS was developed by Matra (presently MBDA) and is called the
Détecteur infrarouge de Départ de Missiles (DDM; missile-launch-detection system). It works in two
infrared (IR) bands to increase detection reliability. Its primary detector is mounted on top of the
Rafale's tail. The LWS was developed by Thales and is called the Détection et Alerte Laser (DAL). The
whole Spectra suite is integrated with three dedicated computers, developed by Thales and MBDA and
called the Gestion de l'Interface et Compatibilité (GIC).

Rafale-M Glass Cockpit
The Rafale received a glass cockpit from the very beginning. Four color monitors were mounted in the
cockpit, one head-level 254x254-mm (10x10-in.) display, one weapon- and system-status monitor
below it, and two smaller 127x127-mm (5x5-in.) displays on each side of the main tactical display. All
displays were developed by Sextant Avionique (presently Thales) with the use of active-matrix and
liquid-crystal display (LCD) technologies. The two small displays are controlled by touch. Thales also
delivered the CTH3022 wide-angle (32x20º) holographic head-up display (HUD).
Rafales are powered by two Snecma M88-2 engines with 72.9 kN of thrust each. Rafales are able
to fly in "supercruise" mode – supersonic flight without the use of afterburners. Supercruise
enables the aircraft to execute a part of the ingress and/or egress route at supersonic speed
without serious penalty to its tactical radius.
All of the Rafale's avionics and electronics were integrated through four Mil Std 1553B data buses and
two Mil Std 1760 data buses. The latter operate in the ADA language and enable use of most modern
types of weapons. Integration was achieved through two Dassault Electronique (presently Thales)
mission computers, replaced by a single, more capable computer on the F2 standard and above. The
heart of the navigation system is formed by two Sagem (Paris, France) Sigma 95N (RL90) lasergyroinertial-
navigation systems (INSs) with embedded GPS receivers from Thales. Thales also
delivered the NC 12E TACAN, the TLS-2020 multi-mode receiver (MMR), and the AHV-17 radar
altimeter, the latter of which was later replaced by the AHV2930. The TLS2020 MMR performs
various functions: instrumental-landing-system (ILS) and microwave-landing-system (MLS) functions
for approach and landing operations and VHF-omnidirectional-range (VOR) functions for en-route
navigation. The AHV2930 digital radio-altimeter has an extended range of 0 to 10,500 feet in altitude
with optimized performance for very low-level flight, as well as a low probability of detection.
The Rafale's communications suite provides secure and interoperable voice and tactical datalink
communications using NATO standards: SATURN (Second-generation Anti-jamming Tactical UHF
for NATO) and MIDS. The Rafale is equipped with two Thales radio sets: the TRA2020 for basic
V/UHF voice communications and the TRA6031 V/UHF radio set, which provides fast-frequencyhopping
SATURN capabilities while being compatible with radios presently in use.
The identification-friend-or-foe (IFF) function is performed by the SB25A Combined Interrogator-
Transponder, also developed by Thales. This new IFF MKXII equipment is the first of its kind using
electronic-scanning technology. It includes Mode S capability is prepared to accept the future Mode 5
IFF waveform
Four Production Standards
The F1 was an interim standard, actually optimized for air-combat missions, since developing the airto-
air fire-control system was a much easier task than the air-to-ground system. Only 13 production
aircraft were built to the F1 standard. The service interested in the F1 was the French Navy, since it
urgently needed a replacement for its aging Vought F-8E(FN) Crusader fighters. Ten of the F1s built
were Rafale M naval single-seat fighters, eight of which equip the 12F Squadron. The three remaining
were two Rafale B two-seat fighters and a single seat Rafale C for the French Air Force. First flight of
the Rafale B took place on Nov. 24, 1998. The Rafale M was flown for the first time on July 7, 1999,
and the Rafale C first flew on April 16, 2003 (and was the last Batch 1 aircraft to leave the factory).
While the F2 standard is not yet the ultimate version of Rafale, it can be treated as fully combat
capable. The F2 is actually the first version that will enter regular service in both the French Air Force
and French Navy. The whole order for the F2 standard, placed in 1999, covers 48 fighters: seven Rafale
Cs and 25 Rafale Bs for the Air Force, and 16 single-seat Rafale Ms for the Navy. Currently, three
production F2s have been built, all two-seat Rafale Bs for the Air Force. The latest of these was handed
over to CEAM (the French Air Force Test Center) in Mont-de-Marsan in April 2005.
The aircraft's avionics system received a new-generation mission computer, more capable than the
previous two combined. It is the Thales Modular Data Processing Unit (MDPU). The core software
system of the MDPU includes mission, displays, cartographic, network, flight-management, and other
critical flight software. The MDPU is connected to 1553 and 3910 data buses. All major systems
onboard the Rafale are connected to the MDPU via interface units. These data buses are completed by
point-to-point video networking, linking aircraft systems with the displays and recording systems.
Developments in the RBE2 radar enabled a ground -mapping mode and Doppler beamsharpening
mode, boosting the aircraft's ground-attack capabilities, since F2 the system can
perform terrain-following and ground-proximity-warning modes. The new radar capabilities
also enabled the integration of more types of air-to-ground weapons on the aircraft.
Rafales of the F2 standard can carry up to two MBDA Apache stand-off missiles (140-km range) or
two MBDA SCALP mini-cruise missiles. The SCALP [Systéme de Crosiére conventional Autonome à
Longue Porté] weighs 1,500 kg and has a range of 400+ km. Laser-guided weapons are also new with
the F2. Up to five GBU-12 or three GBU-10 Paveway IIs can be carried, as well as the French
BGL1000. In the future, Paveway III bombs will also be carried. In the anti-ship role, the Rafale F2 is
to carry two AM39 Exocet Block 2 missiles, although full anti-ship capabilities will await the F3
standard. The conventional-weapon load includes up to 22 bombs weighing 250 kg (French) or 500 lb.
(NATO), up to 10 bombs of 400 kg (French) or 1,000 lb. (NATO), or up to three of 1,000 kg (French)
or 2,000 lb. (NATO). Among the new air-to-air load are the MICA IR infrared-guided medium-range
missiles.
In further development, the Rafale F2 is to be able carry some more air-to-ground guided weapons.
The most interesting of them is the Sagem AASMINS/GPS-guided bomb, something of a
"European JDAM" (see below). Other unspecified weapons are likely to be integrated in the
future, possibly including the Alenia/MBDA PGM-500 and PGM-2000 HAKIM family of laserguided
bombs and the Elbit (Haifa, Israel) Whizzard guided-bomb family, consisting of Lizard
laser-guided and OPHER imaging-infrared-guided bombs.
Under the F2 standard, the Rafale's avionics were integrated with the MIDS tactical informationdistribution
system, working in the Link 16 format. Aircraft are fitted with the MIDS Low Volume
Terminal (MIDS-LVT), developed by the EuroMIDS consortium, which consists of Thales (Colombes,
France), Marconi Selenia Communications (Rome, Italy), Indra Sistemas (Madrid, Spain), and EADS
Deutschland GmbH Defense and Security Systems Division (Unterschleissheim, Germany). The
MIDS-LVT provides Link 16 for real-time tri-service tactical information exchanges with command
centers, airborne early-warning aircraft, warships, and other fighters. The MIDS-LVT also provides two
additional secure voice channels. The system enables the creation of a common recognized tactical
picture. Now the picture obtained from Air Force E-3F AWACS and Navy E-2C Hawkeye aircraft can
be distributed in real time among the Rafale fleet. Also, the aircraft can exchange pictures seen by
onboard radars, as well as imagery from the Damocles pod (see below). One of the most interesting
features of the MIDS is the ability to share data from the Spectra electronic-warfare (EW) system in
real time, fusing it into a common recognized EW-situation picture.
And finally, the ultimate F2 aircraft will receive the Optronique Secteur Frontal (OSF) system (see
below), developed by Thales Optronique in cooperation with Sagem.
After the 1999 order, development of the Rafale was slowed down by French authorities. This was
largely due to the developing concepts of network-centric warfare (NCW), under which information
technologies produced many changes in the fields of tactics and weapons. It was decided that
prolonging the Rafale's development would result in an aircraft that better fit new and future
requirements. Discussion of the requirements for the F3 standard were finalized in late 2003, and
Dassault received a contract for its development in February 2004. In December of that year, an order
was placed for delivery of 59 F3-standard Rafales, bringing the total number of aircraft to 120 (13 F1s
and 48 F2s, plus 59 F3s). This was a major reduction from the previously planned procurement of 234
fighters for the Air Force alone. According to previous plans, many more F1- and F2-standard aircraft
were to have been produced before switching to the F3. Now the numbers of the earlier versions have
been reduced, and production is to be shifted to later-standard aircraft (F3 and F4). Total requirements
of the French Navy call for 60 aircraft (all single-seat Rafale Ms), and the French Air Force ultimately
is to procure 95 Rafale C single-seat and 140 Rafale B two-seat fighters.
The F3 standard aircraft is to receive a modernized radar, but still with the passively scanned antenna. It
will include a range of new modes, such as synthetic aperture radar (SAR), enhancing ground attack
capabilities. Again according to unofficial information, the improved radar can perform various modes
simultaneously, for example air-to-ground and air-search modes at the same time.
The F3-standard aircraft will have full anti-ship capabilities. This means that the RBE2 radar and OSF
will have naval-target-detection and -tracking capabilities. The aircraft will also carry MBDA Exocet
Block 3 missiles and possibly newly developed anti-ship missiles in the future.
As of the F3 standard, the Rafale will gain a reconnaissance capability, allowing the Mirage F1CRs to
be phased out. The Rafale F3 is to carry the newly developed Recce NG pod from Thales Land and
Joint Systems (see below).
F3-standard aircraft will also be equipped with a helmet-mounted cueing system. For a long time, the
Thales Topisght-E system was mentioned in the context of the Rafale, but recently Sagem Gerfaut is
listed as the future provider of Rafale's helmet-mounted cuing system, according to Dassault
information. Both systems are very light and have some helmet-mounted display capability. For the F4
standard, development will probably aim for a full helmet-mounted display and elimination of the
HUD.
Changes in French Air Force doctrine have caused the service to emphasize its procurement of
two-seat Rafale B aircraft at the expense of single-seat Rafale C aircraft (shown here). French
Air Force representatives maintain that the experience from recent conflicts has shown that, in
dense air-defense environments, the workload is too great for a single pilot – a conclusion that
has been reached by many air forces. Intriguingly, the French Navy abandoned its plans to
procure a two-seat version of the Rafale.
The F4 standard has not yet been defined. It is expected that the version will be equipped with
new Snecma M88-3 engines, with 15-20% more thrust to cope with the greater weight of new
avionics and weapons. As for new armaments, Meteor and IRIS-T air-to-air missiles are
mentioned, although a decision regarding their integration on the Rafale has not yet been made.
The F4 standard will also probably include an AESA-type radar. The F4 version is to be
operational after 2010, and most decisions have been deliberately prolonged to enable better
adaptation of requirements to future threats.
As has been suggested above, the development of the aircraft platform is not the only way the French
are planning to expand and improve the mission capabilities of the "Rafale package." A host of sensor
and weapon systems and mission-specific applications will be added to the aircraft over time. Some of
the more important of these parallel development efforts are outlined below.
Damocles Targeting Pod
The Damocles navigation and targeting pod was developed by Thomson-CSF Optronique (now
Thales). The company's experience in this area goes back to the 1970s with the development of the
first-generation ATLIS TV/laser-targeting pod, followed by the second-generation CLDP 8-12μ system
in the early 1990s. Development of the Damocles pod started in the mid 1990s and was partially
financed by the United Arab Emirates (UAE), which had ordered the system for its Mirage 2000-9s.
The Damocles pod has been introduced into French Navy service and is operational on carrier-based
Super Etendard aircraft.
The Damocles pod, in its baseline configuration, has a third-generation thermal-imagery camera,
working in the waveband of 3-5 μm, and a navigational forward-looking IR (FLIR) sensor mounted in
the pylon. The navigational FLIR sensor has a 24x18-degrees field of view. The main sensor is used for
targeting purposes, with selectable fields of view: wide (4x3º), intermediate, and narrow (1x0.75º). It is
fully stabilized, enabling an observation range of up to 40-50 km. Along with the camera, the Damocles
pod is also equipped with two laser sets working in the 1.5- and 1.06-μm wavebands, used for range
finding, target designation, and laser spot tracking. The lasers' ranges enables them to be used from
outside the firing envelope of many air-defense systems. The Damocles camera and lasers can be cued
to the target by other aircraft systems, including indirectly by the RBE2 radar. The pod has also an
automatic track mode. The laser-designation system of the Damocles pod is compatible with Paveway
II and III, Alenia/MBDA PGM-500 and PGM-2000 HAKIM, and Elbit Lizard guided bombs.
Optronique Secteur Frontal (OSF)
Thales also developed a very advanced built-in electro-optical (EO) targeting system for the Rafale,
called Optronique Secteur Frontal (OSF; Front Sector Optronic). The system is mounted in front of the
cockpit and consists of two optical modules. The right-side module has a long-wave (8-12 μm) infrared
camera used for target search and track. The range of the camera is believed to be up to 90 km in ideal
conditions. The left-side module carries a CCD TV camera for daytime target identification. The
system also includes a laser rangefinder for use against air targets.
The OSF system does not replace the Damocles pod. Indeed, the OSF system is primarily an air-to-air
search, track, identification, and localization sensor, with a limited air-to-ground localization and
identification function. The OSF system is to be introduced from the F2 standard onward. In F2.1, it
will be air-to-air capable, and in F2.2 it will also gain an air-to-ground capability. From the F3 standard,
the OSF system is also to be also adapted for anti-ship missions. A future enhancement has been
proposed to the French Air Force and French Navy with a night target-identification function based on
a mid-wave IR sensor that would replace the CCD TV camera.
Recce NG
The Thales Recce NG is intended to be not just a reconnaissance pod. It will be a complete
reconnaissance system. The pod is the airborne element of the system. The ground elements consist of a
mission-planning system and a station for receiving, processing, and disseminating intelligence data in
real time.
The Recce NG system offers the capability to perform both high- and medium-altitude strategic
reconnaissance and low-altitude tactical reconnaissance during the same mission. The system has three
digital optronic sensors: two bi-spectral sensors for long-range reconnaissance (IR and visible) and a
high-speed tactical IR line scanner for low-altitude reconnaissance. The bi-spectral sensors offer several
fields of view – narrow field for medium-range reconnaissance and very narrow field for long-range,
stand-off reconnaissance. The optics of the visible and IR cameras are mounted on a flexible bearing,
enabling the systems to be directed vertically and at oblique angles in any direction from horizon to
horizon, and with significant agility in azimuth.
The French Navy's relative lack of mid-air refuelling assets may partially explain its reluctance
to pay a range penalty in order to accommodate a second crew member in its Rafales. Here, a
Rafale M gets a drink from a Super Etendard "tanker."
The Recce NG pod also includes a Recce Management System (RMS) that incorporates advanced
operational functions for itinerary surveillance (line search), multiple-point image gathering, ad-hoc
stereoscopic data acquisition (pinpoint tracking), real-time datalink management, and digital recording.
The pod is equipped with two antennas to transmit high-speed image data in the optical range and
another antenna for acquiring and tracking the pod from the ground without a pre-defined air meeting
point. The ground element is fully mobile and includes a mission-planning system. Imagery acquisition
can be pre-planned or reprogrammed in flight. The ground segment includes a transportable ground
terminal and antenna linked to the imagery-acquisition system onboard the pod. Prototype Recce NG
pods are now flying, and the system is expected to be operational on the Rafale after 2008.
AASM: the European JDAM
Among the new weapons that are to be integrated beginning with the Rafale F2 standard, one of the
most interesting is the AASM, developed by Sagem. This is a conversion kit for 500-lb.-class bombs,
such as the Mk82 general-purpose, BLU-111 cluster, and CBEMS/Bang penetration bombs. The
guidance section includes an INS and GPS receiver enabling 10-meter accuracy in any weather. The
whole modernization kit is extremely cheap , which enables air forces to use this type of weapon en
mass to achieve high-destructive effects in a very short time. The bombs are also equipped with folded
wings, which enable a glide range of 15 km when dropped from low altitude or 50 km when dropped
from medium to high altitudes. Another interesting feature is that the guidance processor enables the
pilot or weapons officer to select the angle at which the bomb impacts the target.
Additionally, for contingency-type operations, the guidance section can include not only the INS/GPS
for aiming at a pre-selected point, but also an imaging-IR (IIR) seeker. Use of the IIR seeker restricts
attacks to a single target per "drop," while INS/GPS mode only enables every bomb to be aimed at a
different target and dropped simultaneously. The Rafale can carry up to six AASM bombs on two triple
racks under the wings.
ASMP-A Missiles: Nukes for the Rafale
The F3 standard will be nuclear capable, and Rafale aircraft in the both Navy and Air Force services
will be armed with new ASMP-A missiles. The ASMP-A [Air-Sol Moyenne Portee Ameliore; air-toground,
medium range, improved] missile is to replace the existing ASMP missiles that have been used
since 1988 on the French Air Force's Mirage 2000N and the French Navy's Super Etendard strike
aircraft . The ASMP missile and the French concept of "less-than-strategic" nuclear strikes were
developed during the Cold War with a major European war in mind. Defense requirements and policy
have changed dramatically since then, however. One of the most serious threats to any Western
country's national security is proliferation of weapons and ballistic-missile technologies that would
enable "rogue" states to launch a nuclear attack or threaten to do so. To deal with such situations, as
well as other contingencies involving conflict with established powers, the French MoD decided to
increase its nuclear deterrence capabilities. Now Mirage 2000N K3 or Rafale aircraft, with the
assistance of aerial refueling and/or forward airbases, would be able to attack almost any location in the
world. With the missile's range of over 500 km, in many cases, the attacking aircraft would be able to
launch a strike without penetrating the enemy's territory.
A host of sensor and weapon systems and mission-specific applications will be added to the
Rafale over time. This Rafale B carries the Damocles navigation and targeting pod. The
Damocles pod, in its baseline configuration, has a third-generation thermal-imagery camera, a
navigational forward-looking infrared (FLIR) sensor mounted in the pylon, and a pair of lasers
for range finding, target designation, and laser spot tracking.
The range increase to about 500-600 km is not the only improvement in the new missile. The additional
range is to be achieved without substantially increasing the missile's dimensions and weight.
Ultimately, after the future withdrawal of the Mirage 2000N, the ASMP-A missile would be carried by
the Rafale, from the both land bases and the aircraft carrier Charles de Gaulle, so missile is to fit the
Rafale's existing under-fuselage weapon station. To achieve this task, MBDA used a very modern
liquid-fuel ramjet engine called the Vesta [Vecteur a Stratoreacteur], developed by Aerospatiale
Missiles and Celerg. It was originally designed for the ANF anti-ship missile, development of which
has been cancelled. In addition to its fuel efficiency and high thrust-to-weight ratio, the engine is also
equipped with a thrust-vectoring system, enabling the missile to perform sharp maneuvers. The ASMPA
is to be also fitted with lightweight nuclear warhead called the TNA [Tete Nucleaire Aero-Portee].
Missile guidance is to be developed by Thales Avionics (Paris, France) and will be of an INS/GPS type.
The inertial system will be based on precise laser ring gyros, and the GPS-guidance system will be
provided with anti-jamming devices. The guidance computer will enable the missile to use various
routes and flight profiles to optimize air-defense-penetration capabilities. The missile will be able to
operate over a very broad flight envelope at high-supersonic speed. Also to increase air-defensepenetration
capabilities, the missile is to be built using stealth principles.
Reportedly, 47 nuclear-tripped ASMP-A missiles are to be produced and introduced to service on
Mirage 2000Ns in 2007 and on Rafales a year later. Presently, three Mirage 2000N K2 squadrons can
carry ASMP missiles. Two of these (EC 01.004 Dauphine and EC 02.004 La Fayette) are based at
Luxeuil, with the third (EC 03.004 Limousin) at Istres. The French Navy's 12F Squadron of Rafale Ms
will probably receive the ASMP-A missile as well.
Rafale in Service
In December 2001, the first Rafale Ms were delivered to Navy Squadron 12F at Landivisiau, which had
turned in its F-8E(FN) Crusaders in late 1999. In the spring of 2002, 12F Squadron became operational,
and with seven Rafales, it deployed aboard the aircraft carrier Charles de Gaulle, which went to the
Indian Ocean in support of Operation Enduring Freedom. In June 2002, mock fights were conducted
between Rafales and US Navy F-14s and F/A-18s, with results that reportedly were quite surprising to
the US Navy aviators. According to a French source, the Rafale was hardly detectable by radars on both
types of US aircraft and was always able to conduct the first attack with the use of medium-range
missiles. The Rafale was also very agile and maneuverable in a dog-fight engagements. Also during the
operation, Rafales executed touch-and-go landings of the US Navy aircraft carrier USS John C. Stennis
in a demonstration of NATO interoperability.
In March 2004, Charles de Gaulle again set off to the Indian Ocean, where her embarked Rafale
squadron took part in the Northwind 2004 joint exercises with French Mirage 2000s based at Djibouti
and with Mirage 2000-9s of the UAE. Later, the aircraft took part in the Varuna exercise conducted
with the Indian Navy, and Rafales were matched against Indian Sea Harrier FRS.51s. Another exercise,
Red Shark, conducted with Saudi Arabia, enabled Rafales to conduct practice engagements against
Saudi Tornado F3 aircraft. By the summer of 2004, Rafale Ms had accumulated 4,400 flying hours over
approximately 2,000 sorties and had live-fired 20 Magic-2 and 10 MICA missiles.
The next French Navy squadron to receive Rafales is to be 11F in 2006 and 17F in 2007-2008. The
squadrons will receive F2- and F3-standard aircraft, respectively. It is planned, however, that all Navy
squadrons will be gradually be brought up to the F3 standard. The 11F and 17F Squadrons both
presently fly Super Etendard aircraft, with air-to-surface as their primary mission. Interestingly, in 2004
it was decided not to proceed with the two-seat Rafale N for the Navy, and the first flight of the model,
planned for 2005, has been cancelled. All French Navy aircraft will now be delivered as single-seat
Rafale Ms.
One can speculate as to why the French Navy eliminated the two-seat Rafale N, particularly since the
French Air Force has increased the proportion of two-seat models it plans to order, with (ultimately)
140 two-seat and 95 single-seat aircraft. The official statements of both services are different. Air Force
representatives maintain that the experience from recent conflicts has shown that, in dense air-defense
environments, the workload is too great for a single pilot. That conclusion has been reached by many
air forces. Meanwhile, the French Navy officially announced that development of the two-seat Rafale N
was cancelled as unnecessary, primarily due to high costs.
However, behind these official and somewhat contradictory statements are some other factors. One of
them is that Rafale N was to be heavier by about 1,000 kg than the land-based single-seater, thus
reducing range and combat radius. Moreover, the two-seaters have slightly less internal fuel capacity.
Operating from land bases, the French Air Force is usually able to bring tankers to the mission area for
in-flight refueling, so the two-seater's decrreased range and combat radius penalty are not as important
as for the Navy. Another issue is that after 2015, considerably more of the tasks assigned to manned
tactical aircraft will be undertaken by unmanned combat aerial vehicles (UCAVS), such as the Neuron
being developed by Dassault.
According to the current French assessment, UCAVs will not replace manned aircraft in total but will
operate with them in mixed formations (see "The Robot's Got Your Back"). The man-in-the-loop factor
is very important in dynamically changing tactical situations, in which unexpected circumstances
emerge. Greater integration on UCAVs into the overall framework of modern combat aviation is being
enabled by the network-centric warfare concept. In the future, Rafales equipped with state-of-the-art
sensors and data-exchange capabilities will form the core of sensor-to-shooter networks over enemy
territory, supported by more dedicated sensors (AWACs, Airborne Ground Sensors, and signalsintelligence
platforms) operating over friendly territory. So France's Rafales will also perform a leading
role for the UCAVs in integrated strike packages, essentially serving as "UCAV leaders." In such a
case, the two-seat version is essential for the role. From the Navy perspective, carrier strike groups do
not have the capacity to support large numbers of UCAVs. Moreover, it must be assumed that losses
among UCAVs will be considerably higher than among manned aircraft, and replenishing the
battlegroup's stock of such systems would be difficult. Therefore, French naval aviation will continue to
rely on manned platforms to execute its tactical and strategic missions, so the Navy's requirement for
two-seat Rafales is not as pronounced as in the Air Force.
One could ask why such a capable and technically successful aircraft as the Rafale has had such
a difficult time finding export orders. Is the Rafale what the Russians call a "golden fish," an
expensive but useless piece of military equipment? The Rafale certainly is not cheap. But it is the
most impressive aircraft to come out of Europe in two decades. Time will tell whether the Rafale
will find a home among the great combat aircraft of the world.
The first operational French Air Force unit will be the 1/7 Provence at Saint-Dizier (Base Aérienne
113) beginning in 2006, replacing the Jaguar ground-attack aircraft the squadron currently operates.
Another Jaguar squadron at the base will be the next to convert. All Jaguars will eventually be retired
from the French Air Force and replaced by Rafales. The next aircraft to be replaced by Rafales are
Mirage F1CT fighter-bombers and Mirage F1CR reconnaissance aircraft, between 2008 and 2015. The
Mirage 2000 will remain in service alongside Rafales, at least until 2015. It is planned that, in 2008, the
French Air Force will have 40 Rafales, 30 Mirage 2000-5, 60 Mirage 2000C/D (reduced from 80 in
2005), 60 Mirage 2000D, 40 Mirage 2000N (reduced from 60 in 2005), 40 Mirage F1CR, and 40
Mirage F1CT (reduced from 60 in 2005) aircraft. These are currently authorized strengths, and there is
likely to be some slight variance when the time comes. In 2015, the number of Rafales deployed by the
French Air Force is scheduled to reach 140.
Rafale: Right Now?
The Rafale is a very capable aircraft. It can deliver of up to three to four tons of ordnance within a
tactical radius of 1,050-1,500 km. With a full internal and external fuel load, it can conduct over threeand-
a-half hours of combat air patrol 800 km away from its base, armed with eight air-to-air missiles.
The range on internal fuel is 2,100 km, but with three large drop tanks, it climbs 5,500 km (according
to unofficial figures). Range can be further enhanced by the use of conformal tanks on the upper part of
the connection between the fuselage and wings. The air-to-air and air-to-ground weapons set is very
impressive, enabling all-weather, day and night attack capabilities, including stand-off attacks with
conventional and nuclear payloads. When we add some stealth capabilities – less than F/A-22 Raptor
and F-35 Joint Strike Fighter, but close – then anyone must agree that the Rafale is a great technical
success.
So why has no export customer been found? The answer is complex. First, one has to consider that the
Rafale is an aircraft in a class between the F-16 and F-15 – or maybe more appropriately – in a class
between the F-35 and F/A-22. Regardless, it is not a cheap plane. It is simply not an option for poorer
countries. At the same time, Dassault is offering its successful Mirage 2000 fighter, which benefited
from the down-transfer of some technology from the Rafale. It seems that Dassault does not want the
Rafale to spoil Mirage 2000 sales, and it also does not really want to sell the system before it is fully
mature. From a marketing standpoint, it is possible that some customers might buy the Rafale in the
future to replace Mirage 2000s purchased today, so why skip ahead? Moreover, not all countries may
be offered Rafale, since the aircraft incorporates many critical technologies that are important for
France's security. (The reader might have noticed these security concerns in the amount of "not
officially confirmed" data throughout this article.)
Among the current potential foreign customers of the Rafale are Thailand and Singapore, especially the
latter. The Rafale was not selected in the tender for the Republic of (South) Korea Air Force, losing to
the Boeing (St. Louis, MO) F-15K, a version of the F-15E (see "EW Suite Flies on New Korean F-
15K"). According to Dassault (and most likely it is true), the Rafale was the clear performance winner
in Korea, but political pressure from US sources influenced Korea's choice.
The delay in procurement of the aircraft by France is caused primarily by the rapid development of the
concept of network-centric warfare and its implementation across the armed services. As networkcentric
forces materialize, the allocation of missions and roles between manned and unmanned aircraft
will change considerably, so manned aircraft systems will have to be reconfigured accordingly. Thus, it
is better to wait and adjust aircraft development to emerging requirements than to take the wrong way
prematurely.

The Dassault Rafale

v1.0.2 / 01 nov 06 / greg goebel / public domain

* In the final years of the Cold War, in the belief that the USSR was developing improved fighter aircraft, a number of Western nations began their own efforts to develop advanced "fourth generation" fighters to counter the Soviet threat.

The French entry into this field was the Dassault "Rafale". Although the collapse of the Soviet Union meant that the threat the Western fourth-generation fighters were built to face didn't materialize, air forces still need improved fighters to replace aging existing aircraft, and the Rafale is now going into service. This document provides a history and description of the Rafale.

[1] RAFALE ORIGINS

* Different Western nations had slightly different specific motives for developing a fourth-generation fighter. In the late 1970s, the Armee de l'Air (AdA, the French air force) was already fielding their new Dassault Mirage 2000 multirole fighter, and was considering a next-generation successor. The AdA also was faced over the next two decades with the obsolescence of many of their current first-line aircraft, including the Dassault Mirage III, 5 and F1 fighters; the Dassault Mirage IV bomber; and particularly the SEPECAT Jaguar strike aircraft. The AdA requirement for a replacement emerged as the "Avion de Combat Tactique (ACT / Tactical Combat Aircraft)".

Similarly, the Aeronavale (the French naval air arm) needed a replacement for their Dassault Etendard and Super Etendard strike aircraft, and in particular their US-built Vought F-8 Crusader fighters. The Aeronavale requirement emerged as the "Avion de Combat Marine (ACM / Naval Combat Aircraft).

There were many areas of convergence between the AdA and Aeronavale requirements, and so the two services were able to agree to develop a single multirole fighter to meet their needs. This agreement emerged in the form of a requirement for a demonstrator, designated the "Avion de Combat Experimental (ACX / Experimental Combat Aircraft)", as a first step towards an operational aircraft. The ACX requirement specified an aircraft with a weight of about 9 tonnes (10 tons) that could carry at least six air-to-air missiles (AAMs) in the air combat role, and up to 3,500 kilograms (7,715 pounds) of ordnance over a combat radius of 650 kilometers (405 miles) in the attack role. This would turn out to be a relatively modest specification compared to the aircraft that finally emerged.

Dassault was authorized to begin full development of an ACX demonstrator in early 1983, naming the machine the "Rafale (Squall)", while SNECMA began work on a new afterburning turbofan for the ACX, the "M88". Two Rafale demonstrators were actually specified at the outset, but the order was later cut to one.

There were discussions with other potential European partners before and after this decision, but the French were insistent on developing a machine tailored to their own requirements, with France firmly in the driver's seat, and were not inclined to compromise. Their position was a "nonstarter" and the British, Germans, Italians, and Spanish moved off in 1985 to develop their own fourth generation fighter, the "EuroFighter", in parallel with the Rafale. The French went it almost completely alone in building the Rafale, not even leveraging major subsystems off of foreign technology, as the Swedes did with their Gripen fourth-generation fighter.

* Dassault began work on a "Rafale A" technology demonstrator effort in March 1984, with the machine rolled out on 14 December 1985. It was a sleek, single-seat, canard delta machine, fitted with two General Electric F404-GE-400 afterburning turbofans as used by the US F-18 Hornet, since the SNECMA M88 was not ready at that time. The demonstrator performed its first flight on 4 July 1986. It exceeded Mach 1.3 on its first flight and Mach 1.8 a few days later. The Rafale A made its first formal public debut in September 1986. The demonstrator's capabilities were impressive enough to encourage the French Ministry of Defense to place a production order for the Rafale in April 1988.

The Rafale A continued to perform test flights in support of the development program. Although not capable of carrier operations, its flight test program included approaches and "touch and go" landings on the carriers CLEMENCEAU and FOCH to see if the design had any inherent "show stoppers" for carrier operations. As it turned out, the Rafale A's approach speed was even lower than that of the Super Etendard or the Crusader.

In May 1990, the Rafale A was refitted with one SNECMA M88 afterburning turbofan, intended for production Rafales, replacing the left-side GE F404. The Rafale A was finally retired in 1994, with prototypes for operational Rafales taking its place in the flight test program. The Rafale A ended up on display at EPNER, the French test pilot school in Istres, but was later moved to the Dassault plant at Saint-Cloud. It remained on display there until the local authorities claimed that it was causing an unusual number of traffic accidents on the road outside the plant. Dassault was forced to remove it.

* The production order envisioned three versions of the Rafale:

• The single-seat "Rafale C" for the AdA, where "C" stood for "Chasseur / Fighter".

• The two-seat "Rafale B" for the AdA, where "B" stood for "Biplace".

• The single-seat "Rafale M" for the Aeronavale, where "M" stood for "Marine". Although it wasn't specified at the outset, the Aeronavale also later decided to obtain a two-seat "Rafale BM".

Due to the defense shufflings that followed the end of the Cold War, the Rafale program encountered repeated delays but still managed to go forward. The black-painted "C01" prototype of the Rafale C performed its first flight in May 1991. Although two Rafale C prototypes had been planned, the second was judged redundant, but two prototypes, numbers "M01" and "M02", were built for the Rafale M. M01 took to the air in December 1991 and M02 followed in November 1993. The prototype for the Rafale B two-seater, "B01", performed its initial flight in April 1993, before the flight of M02.

M01 took a trip to the US in the summer of 1992 to perform initial carrier catapult trials at a land-based facility at US Naval Air Station Lakehurst in New Jersey, Europe having no comparable facility. M01 performed its first true carrier landing, on the FOCH, in April 1993.

[2] RAFALE DESCRIBED

* The Rafale C defines a baseline configuration for the Rafale family. The remarks below apply to the Rafale C, and are followed by descriptions of the other variants and their differences from the Rafale C.

The production Rafale has essentially the same general configuration as the Rafale A, but is slightly smaller. It also features changes to reduce its "radar cross section (RCS)", such as improved airframe contours, use of "radar absorbing material (RAM)", and a gold-plated canopy. In fact, for a time in the early 1990s, Dassault advertised the type as the "Rafale D", where "D" stood for "Discreet", to emphasize its semi-stealthy nature.

The Rafale also features much more use of composite materials than the Rafale A, which reduced both the aircraft's RCS and weight. It it relatively small for a twin-engine fighter, with a empty weight about 1,360 kilograms (3,000 pounds) greater than that of a single-engine F-16C and a maximum takeoff weight about 4,535 kilograms (10,000 pounds) greater.

The Rafale is powered by two SNECMA M88-2 turbofans, with 50 kN (5,100 kgp / 11,240 lbf) dry thrust and 75 kN (7,645 kgp / 16,860 lbf) afterburning thrust each, and fitted with "full authority digital engine controls (FADEC)". The engine inlets are fixed. The engines are started by a Microturbo auxiliary power unit (APU), which also provides ground power for aircraft systems. The M88-2 is designed powerful, reliable, and easy to maintain, with a modular configuration that makes it relatively simple to swap out subassemblies. SNECMA is working on an uprated M88-3, which would have 90 kN (9,175 kgp / 20,233 lbf) afterburning thrust. The Rafale will require larger engine intakes for the M88-3, but new intakes can be retrofitted to older aircraft with little difficulty.

The Rafale features a compound-sweep low-mounted main wing, and all-moving high-mounted canard foreplanes mounted just behind the cockpit. The wing has full-span elevons and leading edge slats. There is an airbrake on either side of the fuselage, just forward of the tail.

The Rafale is aerodynamically unstable to provide agility, and the machine features a digital "fly-by-wire (FBW)" system to keep it flying right. The fighter also has excellent short-field capabilities. A brake parachute is fitted in a fairing below the tailfin.

The aircraft has a fixed, removable inflight refueling probe mounted on the upper right side of the nose, and tricycle landing gear. The nose gear has twin wheels and retracts backward, while the main gear have single wheels and hinge in the wings toward the fuselage. The Rafale is designed to be reliable and easy to maintain under austere field conditions.

* The Rafale is fitted with a single 30 millimeter GIAT 791B cannon, mounted on the right engine duct. The GIAT 791B has a cyclic rate of fire of 2,500 rounds per minute, and the fighter carries an ammunition store of 125 rounds.

The Rafale features 14 external stores attachments, including wingtip rails for "dogfighting" AAMs, as well as for airshow smoke generators; three stores pylons under each wing; fore and aft conformal stations for AAMs on each side of the fuselage; and fore and aft centerline pylons. Total external warload capacity is 9,500 kilograms (20,925 pounds). Possible AAM loads include the proven Matra / BAE Dynamics Magic heat-seeking AAM, and the newer Matra / BAE Dyanmics "Missile d'Interception, de Combat d'Autodefense (MICA / Missile for Interception, Combat, & Self-Defense)".

The MICA was designed in parallel with the Rafale development effort. It is a highly agile, relatively long-range missile and comes in two versions, including the MICA IR, a heat-seeker, and the MICA EM (Electromagnetique), which has an active radar seeker. The MICA IR has a "launch before lock" capability allowing it to engage distant targets without giving much warning of its approach through a radar signal. The MICA EM is capable of "fire and forget" operation. In the air defense role, the Rafale can carry up to ten MICAs. Rafale will also very likely carry the long-range, ramjet-powered Matra / BAE Dynamics "Meteor Beyond Visual Range AAM (Meteor BVRAAM)" when that missile becomes available late in the decade.

While the aircraft can carry dumb bombs and unguided rocket pods, the push these days is towards smart munitions. The Rafale will carry US Paveway laser-guided bombs, using the Thales Damocles targeting pod, and the fighter will also carry the Matra-BAE Dynamics "Apache / Scalp" cruise missile. The Apache and Scalp are almost identical externally, with a boxy fuselage, pop-out "switchblade" wings, and a belly air intake, but the Apache carries a submunition warload while the Scalp carries a unitary penetrating warhead. The Apache will not actually be carried by French Rafales, being reserved for the Mirage 2000, but it will be an option for export Rafales.

The French have also introduced a new guided-bomb system, under the designation "Armament Air-Sol Modulaire (AASM / Modular Air To Surface Armament)". ASSM will provide modular components to fit dumb bombs with a Global Positioning System / Inertial Navigation System (GPS/INS) guidance kit, or a INS guidance kit with a "smart" imaging infrared seeker, either guidance system using a nose fin assembly to steer the bomb, as well as a tailfin assembly with a rocket booster and popout fins to increase span and range.

Another store that will be carried by the Rafale is the "Air Sol Moyenne Portee A (ASMPA / Air to Surface Medium Range A)" ramjet-powered, Mach 2.5, nuclear standoff missile. ASMPA is a follow-on to the current ASMP standoff missile carried by the Mirage 2000, with double the range. The Rafale is currently expected to obtain the ASMPA in 2009. An antiship variant of the ASMPA, the "ANF", is also being considered, but the Rafale will be qualified for the proven Exocet solid-fuel antiship missile in any case.

French Rafales will be able to carry the "Reconnaissance Nouvelle Generation (Reco NG)" digital reconnaissance pod, which will contain day-night electro-optical sensors, resident processing power, a solid-state recorder, and a high-speed datalink. The Reco NG is now in service for use on Mirage 2000N fighters, and will begin service with the Rafale in 2008.

The Rafale's rear centerline pylon and the two inner wing pylons on each wing are "wet" and can be used for carriage of external tanks. All five wet pylons can carry 1,150 liter (304 US gallon) fuel tanks or 1,250 liter (330 US gallon) supersonic fuel tanks. Up to three of the big bulbous-nosed 2,000 liter (528 US gallon) external tanks, much like those developed for the Mirage 2000 but lacking tailfins, can also be carried, with one on the centerline pylon and one on the inner wet pylon on each wing.

* The pilot sits on a Martin-Baker Mark 16F "zero-zero" (zero speed, zero altitude) ejection seat, inclined 29 degrees to improve pilot tolerance to gee forces, under a canopy that hinges open to the right. An "on-board oxygen generating system (OBOGS)" is provided to eliminate the need to stockpile oxygen canisters.

The pilot flies the aircraft with a sidestick controller mounted on the right side of the seat and a throttle on the left, with both studded with "hands on throttle and stick" controls. The Rafale will also provide "direct voice input (DVI)" capabilities, allowing the pilot to perform actions through spoken commands. The DVI system will have a vocabulary of 90 to 300 words, with first-time recognition 95% of the time. DVI will not be included in initial production Rafales.

The Rafale features a "glass cockpit" and a comprehensive combat avionics suite. The glass cockpit is startlingly austere and would probably come as a complete shock to a fighter pilot from the days of dials and indicators. It includes a wide-angle holographic "head up display (HUD)" to display most of the relevant information using sophisticated symbology, and two accessory color flat-panel multifunction displays (MFDs) with touch input overlays. Pilots will wear special silk-lined leather gloves with no seams on the fingertips to use the touch overlays, and the gloves will also have chamois pads for cleaning the screens. In addition, in full development, the pilot will have a Sagem Gerfaut helmet-mounted sight.

The avionics suite includes:

• A multimode radar system, the Thales (previously Thomson-CSF) "Radar a Balayage Electronique 2 (RBE2)". It uses a phased array (electronically steered) antenna, has a range of up to 100 kilometers (60 miles), and is advertised as the first "look-down / shoot-down" airborne multimode phased-array radar developed in Europe.

  The RBE2 can track up to 40 targets and engage up to eight of them at once with the MICA EM, performing automatic "identification friend or foe (IFF)" interrogation when in dogfight mode. It also supports air-to-surface attack for both ground and naval targets, as well as navigation and automatic terrain following modes, and can operate in intense jamming environments.

  Functions such as terrain following can be used while tracking targets elsewhere. A "synthetic aperture radar (SAR)" mode is also being developed to provide a radar imaging capability for targeting and reconnaissance.

• An optical sensor suite, the Thales / Sagem "Optronique Sector Frontale (OSF)" or "Frontal Sector Optronics (FSO)" system, mounted on the nose in front of the windscreen. A wide-angle "infrared search and track (IRST)" unit is mounted on the left, and a TV / laser rangefinder unit known as a "combat identification unit (CIU)" is mounted on the right. The CIU can track a target and display it on the pilot's HUD, with modes allowing it to automatically select targets.

• A ring-laser gyro inertial navigation system with a GPS receiver.

• A voice and data communications suite, including a secure "Have Quick" radio system and a "Link 16" tactical datalink.

• The Thales / Matra BAE Dynamics "Self-Protection Equipment Countering Threats to Rafale Aircraft (SPECTRA)" defensive countermeasures system. SPECTRA includes radar, laser, and missile warning sensors, along with active jamming and four chaff-flare dispensers, and can automatically identify and categorize threats and take the necessary defensive actions.

  SPECTRA's elements are all built into the airframe, ensuring that all stores pylons are free for carriage of stores. Receiving antennas are mounted alongside the engine intakes and in a module on the top of the tailfin, with the module also incorporating laser warning sensors. Jammer antennas are also fitted in the canard mounts, and laser warning sensors are mounted on each side of the fuselage below the cockpit. The upward-firing chaff-flare launchers are fitted on the fuselage, just forward of the engine exhausts, in the wing roots.

  SPECTRA can record threat data obtained during a mission to provide electronic intelligence. Ultimately, Rafale datalink capabilities will allow multiple Rafales to use their SPECTRA systems cooperatively to pinpoint adversary emitters.

  It appears that Thales has been working on "active cancellation" technology for the SPECTRA system, with the jamming transmitters picking up a hostile radar and then feeding back the signals out-of-phase to cancel out the echo from the aircraft. The French have been quiet about this capability and it is probably a future item.

• A mission computer, the "Modular Data Processing Unit (MDPU)", based on commercial components. The MDPU provides redundancy and high throughput, and features a modular design that makes it easy to update. It coordinates and controls all the aircraft's avionics. It also runs an integrated aircraft health monitoring and maintenance-data system, and performs "sensor fusion" to give the pilot a seamless view of what the aircraft's sensor systems see in the world around them.

* The Rafale B is very similar to the Rafale C, except of course for the tandem seats. The two seats are covered by a one-piece canopy that hinges open to the right. The Rafale B is fully equipped with operational kit, and the control layout for the front and back seats is as similar as possible to ensure maximum operational flexibility. It has an empty weight about 350 kilograms (772 pounds) greater than the Rafale C, and less internal fuel capacity.

The Rafale B was originally seen primarily as a conversion trainer, to be purchased in small quantities. It was believed that improvements in aircraft avionics would allow the pilot of the single-seat Rafale C to perform all operational missions. However, the Gulf War in 1991 demonstrated to the AdA that strike and reconnaissance missions often required two aircrew, and so the service then increased the proportion of two-seaters in their buy.

* The Rafale M is very similar to the Rafale C, the only really visible differences being taller, longer nose gear, with catapult attachment fixtures, and fit of a stinger-type arresting hook under the tail. The longer nose gear, which gives the Rafale M a nose-up attitude on the ground, required removal of the front centerline stores pylon.

The Rafale C and B actually do have a runway arresting hook, but it is much less prominent. The Rafale M requires a much more formidable since a carrier jet snags the cable at full throttle in case the landing is a "bolter" and the aircraft has to come around for another try.

Other changes to the Rafale M include a stronger airframe and main gear to withstand "smackdown" landings on carriers; a built-in, power-operated pilot boarding ladder; a carrier microwave landing system that makes landings procedure much easier than with earlier French carrier aircraft; and a "Telemir" inertial navigation system that can obtain position reference data from the carrier.

The modifications to the Rafale M added about 500 kilograms (1,100 pounds) to its empty weight relative to the Rafale C. In the interests of commonality with other Rafale variants, the Rafale M does not have folding wings.

[3] RAFALE INTO SERVICE

* Although the Rafale development program has gone well, the program has not gone quite so smoothly politically. The generally unexpected end of the Cold War caused complications for all the Western fourth-generation fighter efforts, resulting in program stretchouts and reduced buys.

First flight of a production Rafale, an Aeronavale Rafale M, was in July 1999, the same day the M02 prototype Rafale M landed on the new French aircraft carrier CHARLES DE GAULLE. The Aeronavale's requirements were regarded as more pressing than those of the AdA, since the Aeronavale's "first line" air combat fighter was the honored but antiquated Vought Crusader, while the AdA had the perfectly modern Mirage 2000.

Initial service deliveries of the Rafale M were in December 2001, with the first Aeronavale Rafale M squadron fully operational, on the CHARLES DE GAULLE, in the summer of 2002. As with the EuroFighter, the Rafale is going into service in a phased fashion:

• The first Rafales to be delivered are configured to "F1" standard, which only includes capabilities for air-to-air combat and a baseline avionics suite. They armed with cannon and the Magic and MICA EM missiles.

  The first few production Rafale Ms, which were put into service in a relative hurry, were delivered in a "sub-F1" standard designated "LF1", which featured an older mission computer instead of the MDPU and lacked the built-in cannon. The LF1 machines have since been improved to F1 standard.

• The "F2" standard, now being introduced, adds strike capabilities, including carriage of the Apache / Scalp cruise missile; provision of air-to-surface and terrain-following modes to the RBE2 radar; and brings the OSF sensors and Link 16 datalink on board. Along with the surface attack weapons, the F2 specification permits carriage of the MICA IR, replacing the Magic, and Rafale Ms will also be able to carry a buddy tanker pod.

• The definitive "F3" standard, scheduled for introduction in 2008, will bring the Rafale up to full multirole operational capability, with implementation of all currently planned modes for the RBE2 radar, adding AASM capability, as well as missions such as nuclear strike, with the ASMPA; antiship attack with the Exocet or ANF; and reconnaissance with the Reco NG pod.

  The F3 standard will also add DVI, the Gerfaut helmet-mounted sight, and support for an improved tanker pack. All F1 and F2 standard Rafales will be brought up to F3 standard in the course of scheduled high-level maintenance. There is also some talk of fitting the uprated M88-3 engines.

An F4 standard is being considered but has not yet been defined.

The Aeronavale expects to receive its first F3-standard full multirole single-seat Rafale M in 2007. All 60 Aeronavale machines are expected to be delivered by 2012. Although the Aeronavale had planned that 35 of the 60 would be Rafale BM two-seaters, the Rafale BM was cancelled in late 2004 as an economy measure. Ironically, the planned uses of the money released by the cancellation included updates to Rafale systems that had become obsolete during the extended development cycle, as well as funding for the next Rafale production batch.

Initial delivery to the AdA, of a two-seat Rafale B, was in December 2000. By late 2004, 61 Rafales had been delivered to the AdA, with 27 of them being Rafale B two-seaters. Introduction to operational AdA squadron service, with aircraft to F2 standard, was in the summer of 2006. Some of the aircraft were placed on "quick reaction alert" to help defend against terrorist actions, and the AdA expects to fly their Rafales with the NATO Reaction Force. There were hints about deploying them to support French forces in Afghanistan as well.

The AdA expects to obtain 212 Rafales. Originally the plan had been for 60% of them to be two-seaters, but along with the cancellation of the Rafale BM in late 2004, the decision was made to only acquire two-seaters for conversion training and the nuclear strike mission, reducing the proportion of two-seaters to about 40%. Dassault officials believe that the improved software provided by the F2 and F3 standards will allow the single-seaters to perform complex missions without overwhelming the pilot.

* Dassault officials are considering next-generation improvements to the Rafale. One high-profile future option is next-generation computing systems and data links to allow a two-seat Rafale B to control unmanned aerial vehicles (UAVs) for reconnaissance and strike support.

Reconnaissance UAVs would be able to identify targets and even designate them with a laser for attacks with guided munitions launched by the Rafale, or an armed UAV could perform the attacks directly. Communications between the Rafale and the UAVs could be performed over satellite links, and such communications links could also be used by the Rafale to obtain information from surveillance platforms, such as an AWACS or Joint-STARS aircraft.

Another improvement in planning is an "Active Electronically Scanned Array (AESA)" version of the RBE2 radar. An AESA can be thought of as an "RF array processor", made up of a grid of "transmit/receive (T/R)" modules that each have transmitter and receiver circuitry. The T/R modules operate together, with some modules being programmed to perform one set of functions, say to operate as a radar, while others simultaneously operate as, say, a jammer. In the summer of 2004, Thales was awarded a contract to develop an AESA antenna, with a demonstrator flying by the fall of that year. Dassault officials hope that AESA radar deliveries will begin as early as 2008. The F3 standard already includes support for an AESA.

* Dassault has banded together with Thales and SNECMA in the "Rafale International" business group, which is working on a Mark 2 export version of the fighter. Dassault has a 60% share in the group, while Thales and SNECMA both have a 20% share. The Rafale Mk.2 will have the uprated SNECMA M88-3 powerplant with 20% more thrust; improved ground attack software; the AESA RBE2 radar; and conformal fuel tanks.

So far, the Rafale has won no export orders. In 2002, Dassault lost the award for a South Korean competition to the Boeing F-15, which frustrated Dassault officials to the point where they considered for a time a legal challenge to the award. Ironically, Dassault is still having good luck with export sales of the cheaper Mirage 2000, with the latest versions of this proven fighter benefiting from technology developed for the Rafale.

GERFAUT: SAFRAN’s eye, sharper and sharper

GERFAUT: SAFRAN’s eye, sharper and sharper
Military Aviation and Defense | Wednesday 11 May 2005

Sagem Défense Sécurité, a SAFRAN Group subsidiary, now enters the select few members of HMDS manufacturers by winning, with the Gerfaut HMDS, the competition for the development, the industrialisation and the serial production of the HMDS for the Rafale aircraft.

Technological breakthrough: miniaturisation of LCD displays and optical Head Tracking System (HTS)

The new generation combat avionics systems comprise equipment that multiplies the offensive capacities of the aircraft : the Helmet Mounted Display & Sight (HMDS). With the help of this new helmet, which provides symbology on the visor, the pilot can designate his target simply by looking at it thus saving previous seconds in dogfight, which gives full meaning to the saying “first sight, first shot”.

Technological breakthrough

The Gerfaut success once again demonstrates the ability of SAFRAN Group companies to choose the technological breakthrough at the right time, here with the miniaturisation of LCD displays and the optical Head Tracking System (HTS).

Regarding the LCD displays, they are already part of mature technologies used in the field of military avionics and it is the miniaturisation that can be achieved today (here, for the Gerfaut, the size of the display is similar to the one of a 1 Euro coin) that makes them nicely suitable of HMDS applications since they dramatically outcome their predecessors, the Cathode Ray Tubes (CRT): light weight, no high voltage in the helmet, no distorsion due to temperature. The use of such displays significantly improves the ergonomy of the helmet and enables the pilot to concentrate on his mission.

For the French Rafale, 336 Gerfaut HMDS have been ordered so far

Growth opportunities

Regarding the optical Head Tracking System, this is based on the following principle: clusters of Light Emitting Diodes (LED), the geometry of which being well known, are fitted on the helmet outer shell and are continuously recorded by small cameras installed in the aircraft cabin. Image processing, at high frequency, allows to restitute the geometry of the clusters and thus to compute the position and line of sight of the pilot. Compared to previous techniques, the major advantages of this optical technology is the accuracy and the immunity to electromagnetic perturbations; this enables the pilot to force his missile seekers or his optical captors on the line of sight indicated by his head.

For the French RAFALE, 336 Gerfaut HMDS have been ordered so far. The Gerfaut is also part of the avionics suite of the export Rafale. With this success in the field of individual equipment for pilots, Sagem Défense Sécurité enters new growth opportunities.

IRST & Missile warning system & Gerfaut helmet-mounted display

IRST

IRST (Infra Red Search and Track) are passive infrared surveillance systems, allowing automatic detection and multitarget tracking on modern fighter aircrafts. Compared to radars, they are fully passive and insure a complete stealthiness of the aircraft.

Thus, Rafale aircraft is fitted with Front Sector Optronics (FSO), multi-spectral (IR and TV) equipment, in which the IR Surveillance and Imagery channel is developed by Sagem Défense Sécurité. The IR Surveillance and Imagery channel implement sophisticated processing algorithms for automatic detection and tracking of aerial threats and ground targets, providing the mission system with data allowing the operation of aircraft weapons.

Missile warning system

Sagem Défense Sécurité has developed the SAMIR system to protect fighter planes. Several hundred products have been delivered to equip Mirage 2000 and Rafale aircraft.

The SAMIR system consists of two infrared sensors mounted on either side of the Rafale's tail fin. Each sensor is a wide-field imager which is passive and therefore discreet. Radiometric and time-based algorithms enable missiles that represent a threat to the outfitted aircraft to be detected with a very low false alert rate. Information provided by SAMIR enables decoy/jamming tactics to be employed.

Gerfaut helmet-mounted display

This equipment is developed by Sagem Défense Sécurité for the Rafale and can be adapted to any other aircraft. It is mainly used for air-to-air close-combat missions. It enables the target to be located by measuring the position of the pilot's head when facing the target. The position of the helmet is obtained in real time using optronic techniques (diodes on the helmet and micro-cameras in the cockpit).
