It has a radar cross-section similar to that of a Super Hornet. That means it is nowhere near as stealthy as an F-35.
by Sebastien Roblin
In January 2019, French Defense Minister Florence Parly announced France would commit $2.3 billion to develop an F4 generation of the Dassault Rafale twin-engine multirole fighter. This would include production in 2022–2024 of the last twenty-eight of the original order of 180 Rafales, followed by the purchase of an additional thirty Rafales F4.2s between 2027–2030, for a total of 210. Since 2008, France has deployed land- and carrier-based Rafales into combat in Afghanistan, Iraq, Libya, Mali and Syria.
Despite incorporating stealth technology, the Rafale (“Burst of Fire” or “Gust of Wind”), is not a true stealth aircraft like the F-35. True, the French jet's wings and fuselage are primarily composed of radar-absorbent composite materials and lightweight titanium. Other stealthy design features include S-shaped engine inlets, serrated edges and a channel exhaust cooling scheme designed to reduce infrared signature.
These give the Rafale an estimated Radar Cross Section (RCS) of slightly above one square meters—comparable to peers like the Super Hornet and Typhoon, but orders of magnitude greater than that of the F-35 jet. Land-based Rafales are currently priced $76–$82 million per plane, only modestly cheaper than the F-35A which benefits from vastly greater economy of scale, though the Rafale's operating costs are likely lower.
Paris particularly prizes maintaining an independent domestic arms industry and has never seriously considered purchasing F-35s. Instead, France is working with Germany and other partners to develop a sixth-generation Future Combat Air System stealth jet to enter service in 2035-2040. Until then, France is doubling down on the 4.5-generation Rafale by integrating additional F-35-style avionics and improving its network-centric warfare capabilities.
The Rafale is much more agile than the F-35, with superior climb rate, sustained turn performance, and ability to super-cruise (maintain supersonic flight without using fuel-gulping afterburners) at Mach 1.4 while carrying weapons. The Rafale's all-moving canards—a second set of small wings near the nose—give the Rafale excellent lift and low-altitude speed and performance, as you can see in this majestic airshow display.
However, compared to larger fourth-generation twin-engine jets like the Su-35 or F-15, the Rafale can't fly quite as high (service-ceiling of 50,000 instead of 60,000 ft), and has a lower maximum speed (only Mach 1.8 compared to Mach 2-2.5).
The Rafale's agility won't help as much if it is engaged at long distances by enemy surface-to-air missiles and stealth jets. To compensate, the Rafale boasts an advanced Spectra electronic warfare system that supposedly can reduce the Rafale's cross-section several times over—it is rumored by reflecting back signals using ‘active canceling.' Spectra also incorporates powerful jammers and flare and chaff dispensers, provides 360-degree early-warning, and can even assist Rafale pilots in targeting weapons to retaliate against attackers.
Spectra's capabilities reportedly allowed Rafales to deploy on raids over Libyan airspace in 2011 before air defense missiles had been knocked out.
Other key capabilities include sensor fusion of the Rafale's RBE-2AA Active Electronically Scanned Array multi-mode radar, which can track numerous targets over 124 miles away, with its discrete OSF infrared-search and track system, which has an unusually long range of sixty-two miles. Rafale pilots also benefit from uncluttered instrumentation combining voice command with flat-panel touch screens.
The multirole jet carries a punchy thirty-millimeter revolver cannon and up to twenty-one thousand pounds of weapons on fourteen hardpoints, making it a versatile air-to-ground platform. Because Paris requires expeditionary capability in Africa, the Rafale can refuel in flight and carry up to five fuel tanks for very long transits, and can be operated from relatively unprepared airfields, unlike most high-performance jets.
What's new in the Rafale F4?
Dassault produces three basic types of Rafales: the single-seat Rafale-C, the two-seat Rafale-B (the additional weapon systems officer being preferred for strike and reconnaissance missions) and the carrier-based single-seat Rafale-M, which has an arrestor hook, reinforced landing gear and buddy-refueling pod capability. Each type has evolved in common generations designated F1, F2, F3 and F3R.
The F4 generation introduces additional network-centric warfare capabilities and data-logistics similar to those on the F-35 Lightning, enabling Rafales on patrol to build a more accurate picture of the battlespace by pooling their sensors over a secure network, and even exchange data using new satellite communications antenna. The pilots also benefit from improved helmet-mounted displays.
The Spectra defensive system will receive more powerful jammers and new threat libraries tailored to meet the improving capabilities of potential adversaries. Furthermore, Dassault seeks to use “Big Data” technology to develop a predictive maintenance system reminiscent of the F-35's troubled ALIS system to cost-efficiently implement preventative repairs.
Other systems to be tweaked include the air-to-ground mode of the RBE-2AA radar, the M88 turbofan's digital computers, and a new AI-system for its reconnaissance and targeting pod allowing it to rapidly analyze and present information to the pilot. Rafale-Ms will also receive a new automated carrier landing system.
New weapons set for integration most notably an improved model of the Mica short-to-medium range air-to-air missile, which has a range of forty-nine miles. The Mica can be launched without initially being locked and guided remotely by a data link on the fighter before engaging either an infrared or AESA radar seeker to close in for the kill, using a vector-thrust motor to pull off tight maneuvers. Because both the Rafale and the Mica missile can employ passive infrared targeting without using an indiscrete active-radar for guidance, the MICA can be launched with little warning for the target.
The Mica-NG model will incorporate new infrared-matrix sensors for better performance versus stealth fighters, carry additional propellant for longer range, and integrate internal sensors to reduce maintenance costs. Its dual pulse motor will allow it to accelerate just prior to detonation for a greater probability of achieving a kill.
For longer range engagements, newer Rafales F3Rs and F4s can launch British Meteor missiles which can sustain Mach 4 speeds.
Another weapon set for integration is heavier 2,200-pound variants of the AASM HAMMER, a guidance kit similar to the U.S. JDAM. Previously, the Rafale could only carry 485-pound variants of the weapon which can use either GPS-, laser- or -infrared guidance to deliver precise strikes. Unlike the JDAM, the HAMMER also incorporates a rocket-motor, allowing it to hit targets up to thirty-seven miles away when released at high altitude.
The Rafale will also be modified to integrate future upgrades of the French SCALP-EG stealthy subsonic cruise missile and the supersonic ASMP-A cruise missile which carries a 300-kiloton-yield nuclear warhead. Reportedly France may develop a hypersonic AS4NG variant increasing range from 300 miles to over 660 miles.
Currently, the French Armée de l'Aire has three Rafale multi-role squadrons and two nuclear-strike squadrons based in Mont-de-Marsan (south-western France), Saint-Dizier (north-eastern France) and al-Dhafra in the UAE. There are also an operational conversion unit and a testing and evaluation squadron.
The French Navy has three Rafale-M squadrons which rotate onboard France's nuclear-powered carrier Charles de Gaulle. In 2018, a squadron of Rafale-Ms proved their capability to operate from the U.S. carrier George H. W. Bush.
The forthcoming Rafale F4s will progressively replace France's fourth-generation Mirage 2000s, over 110 of which remain in service today. French periodical Le Figaro claims that older Rafales will also eventually be updated to the F4 standard.
Abroad, Dassault is finish delivery of orders from Egypt (twenty-four), Qatar (thirty-six) and India (thirty-six). All three countries may order additional Rafales, though the price of its initial Rafale order has caused a political scandal in New Delhi.
As France must wait nearly two decades before a European stealth fighter can enter service, its armed forces are betting that in the interim adding networked sensors and weapons to the Rafale's superior kinematic performance and powerful electronic warfare systems will keep the agile jet relevant in an era of proliferating stealth aircraft and long-range surface-to-air missiles.

Safran Electronics & Defense et Sodern offrent à la France une technologie inédite, applicable à plusieurs domaines stratégiques. Un nouveau potentiel de croissance économique pour les industriels. Un projet innovant Nous avions présenté en juin 2020 le projet de système de navigation innovant qui vise les étoiles en plein jour, et est capable de fonctionner sur avion, malgré le Soleil et au travers de l'atmosphère. Le projet est développé depuis 2016 par Safran Electronics & Defense (responsable du projet et de la fonction navigation) et Sodern (responsable de la fonction de visée stellaire), à la demande de la Direction Générale de l'Armement (DGA) et de l'Agence de l'innovation de défense (AID). Désormais appelé Vision, le démonstrateur de visée stellaire diurne a été testé pour la première fois en novembre-décembre dernier à bord d'un banc d'essais volant. Embarquement sur banc d'essai volant Quatre vols d'essais (trois de jour et un de nuit) ont été réalisés par la DGA Maîtrise de l'information (DGA MI), l'expert technique du Ministère des Armées pour les systèmes d'information et de communication, la cybersécurité, la guerre électronique et les systèmes de missiles tactiques et stratégiques. Les vols ont duré une dizaine d'heures au total, à différentes altitudes. Tout au long des trajectoires de chaque vol, de nombreuses étoilées ont été accrochées et poursuivies de manière fine par le démonstrateur. Vers une production en série La France se retrouve ainsi pionnière sur cette technologie d'avant-garde, tandis que Sodern y voit un fort potentiel de croissance. Le concept désormais prouvé, l'industriel prévoit de développer un prototype raffiné cette année, puis préparer la production en série du produit d'ici 2025, d'abord pour les Armées, puis éventuellement pour le marché civil. C'est un grand nombre d'appareils qui pourrait bénéficier de ces nouveaux viseurs d'étoiles : aéronefs de transport et de ravitaillement, drones longue endurance, avions d'arme, navires, voire même, selon l'AID, des missiles à long terme. Sodern se réjouit que sa technologie puisse ainsi profiter à d'autres technologies et être essaimée dans d'autres secteurs. https://www.air-cosmos.com/article/la-dga-officialise-la-russite-des-premiers-essais-en-vol-du-viseur-dtoiles-diurne-vision-24060

"I think a three month slow-down in program activity is an optimistic projection based on the level of damage the economy is currently sustaining." By PAUL MCLEARYon April 21, 2020 at 3:33 PM WASHINGTON: Defense industry and Pentagon leaders are struggling to assess what impact the COVID-19 pandemic will have on building and maintaining the global US arsenal, but early assessments agree there'll be some disruption and delay as the global economy teeters. How much, how long, and where those disruptions will occur are something of an open question. With massive supply chains across the globe that run from small mom and pop manufacturing shops to massive global conglomerates, there's no one formula to assess what will happen to the industrial base in the weeks and months to come. On Monday, Pentagon acquisition chief Ellen Lord said she expects the largest programs to see three-month delays, but some analysts say that assessment could be too rosy. “I think a three month slow-down in program activity is an optimistic projection based on the level of damage the economy is currently sustaining,” said Andrew Hunter, former chief of staff to two heads of Pentagon acquisition. Hunter is now at the Center for Strategic and International Studies. The designation of the defense industry as critical infrastructure has ensured that shipyards, factories, and shops have generally remained open, as workers stagger shifts and companies provide liberal leave and teleworking where possible. That has placed the defense industry in a good position relative to other parts of the economy. But the supply chain those companies rely on “is tightly interlinked with the commercial economy, especially the aviation and automotive sectors, and this will transmit a degree of economic disruption into defense in the coming months,” Hunter said. Lord singled out the aerospace sector, along with shipyards and space launch as areas most at risk of slowdown and disruption. So far, though, the Navy and its largest shipbuilder say they're mostly working through the issues, and are staying away from putting a specific length of time on any delays. “We do not have a list of programs that are delayed, but as Ms. Lord and [Navy acquisition head James] Guerts have both said, while it's too soon to identify specific delays, generally we are expecting and planning for program disruptions,” Navy spokesman Capt. Danny Hernandez told me in an email. Geurts has moved to accelerate funding for some work and parts supplies so industry can eventually ramp up once the entire workforce is back on the job. Speaking to reporters last week, Geurts said over the “next three four weeks we'll get a better view of the exact delay and disruption and then how we might mitigate that, or quite frankly, where do we have opportunities where we can accelerate things” due to some excess capacity in the supply base because it's not being consumed by commercial aviation or shipbuilding. At the country's largest shipbuilder, Huntington Ingalls, company executives told me recently they're not seeing significant reductions in the number of parts they're receiving. “We are working with a few critical suppliers that are having challenges, but I think for the most part are going to be able to get through that,” said Lucas Hicks, vice president of new construction aircraft carrier programs. “We have reached out to all the suppliers and are working with them to try to help them.” There will be some pain, though how much is up for debate. Analyst Byron Callan of Capital Alpha Partners said in a note Monday that a three-month impact might not force companies to drastically change their expectations for the whole year. Any slippages this spring “could conceivably be made up in subsequent months, but that may be a challenge. Contractors could sustain prior guidance and just call out COVID-19 as a risk for the full year, or drop guidance altogether. No one has a perfect crystal ball.” Hawk Carlisle, president of the National Defense Industrial Association, said on a Monday conference call organized by the Jewish Institute for National Security of America that the slowdown in the global economy “is going to cause things to cost more, whether it's service agreements or products and manufacturing capability.” He's looking to the next congressional stimulus package for an acknowledgment “that these programs are going to exceed budget,” he added, “because of this two to three months of delays, partial workforce, paying the workforce, inability to perform on contract.” But Hunter thinks, so far, the Pentagon has handled the situation as well as can be expected: “To the department's credit, they have been aggressively looking for issues in the supply chain, which means that Ms. Lord's estimate becomes a lot more likely if they succeed in staying ahead of these problems.” https://breakingdefense.com/2020/04/pentagon-industry-struggle-to-chart-impacts-of-covid-on-arsenal
