“The [French] Air Force will benefit from more Rafale orders. This is imperative in the current context,” declared President Emmanuel Macron last spring, setting the Rafale F5 not just as an upgrade, but as a keystone of France’s future air power. Scheduled for deployment in about 2030, the Dassault Rafale F5, or the “Super Rafale,” is being designed to push aside the American F‑35 monopoly using a combination of propulsion technology, hypersonic strike power, and manned‑unmanned combat.
Safran’s M88 T‑REX engine is at the center of the revolution a re-engineered version of the existing M88. Producing 88 kN (19,841 lbf) of thrust with afterburner a 20 percent boost over the previous engine the T‑REX does this without increasing engine size or compromising fuel efficiency. Safran attributes “significant, targeted upgrades” such as a more efficient low-pressure compressor, new high-temperature materials, more effective turbine cooling, and an aerodynamically optimized nozzle. Christophe Bruneau, the executive vice-president of military engines at Safran, indicated that the program will “push the boundaries of the M88’s performance to meet the evolving needs of our armed forces customers in an increasingly unstable geopolitical context.” T‑REX and standard M88 module compatibility will ease fleet maintenance and logistics, an important consideration since France intends to fly Rafales through the 2060s.
The F5’s sensor suite is no less ambitious. Its successor Thales RBE2 XG radar will increase detection range, enhance multi‑target tracking, and incorporate sophisticated data fusion. Combined with an upgraded electronic warfare package, the aircraft will create what Dassault terms an impenetrable “self‑defense bubble,” able to jam hostile radars and spoof missile seekers. Such systems are intended to function in contested electromagnetic environments, where survivability depends on both stealth shaping and active countermeasures.
The most revolutionary addition is arguably the ASN4G hypersonic nuclear missile. MBDA designed ASN4G with ONERA research assistance, using a ramjet to maintain Mach 6–7 speeds and 35 km altitude with range over 1,000 km. Its stealth‑designed airframe, X‑shaped tailplane, and radar-absorbing materials decrease radar cross‑section to as little as 0.07 m². Side‑mounted RF‑transparent panels hide passive sensors and electronic warfare antennas, allowing the missile to detect and jam advanced air defense systems like the S‑400 or S‑500. At such speeds, interception is only possible by the very fastest interceptors, and even then within very limited engagement windows. ASN4G will succeed the ASMPA, maintaining France’s airborne nuclear deterrent deep into the 21st century.
The F5 will also be equipped with the Future Cruise Missile and Future Anti‑Ship Missile (FCM/FASM), collaborative UK‑French development under the FC/ASW program to substitute SCALP/Storm Shadow and Exocet. Two variants are being developed in parallel: a high‑subsonic, low‑observable variant optimized for penetration through thick air defenses, and a high‑supersonic ramjet‑powered anti‑ship variant. These weapons will provide the Rafale F5 with long‑range precision strike capabilities against both seaborne and hardened land targets, including suppression of enemy air defenses (SEAD).
Also revolutionary is the integration of Dassault’s new Unmanned Combat Air System (UCAS), a stealthy flying‑wing drone based on the nEUROn demonstrator. With a maximum take‑off weight of 14–16 tonnes and a wingspan of approximately 12–14 meters, the UCAS is intended for deep penetration missions, SEAD/DEAD, and reconnaissance. Its non‑afterburning M88 engine, dorsal intake, and cooled exhaust reduce radar and infrared signatures. The UCAS will be commanded by a Rafale F5 pilot as a mission manager, not as remote pilot, while onboard AI does navigation, target recognition, and threat evasion. This manned-unmanned teaming (MUM‑T) enables the Rafale to stay beyond the highest density threat zones while loyal wingman drones carry out high-risk attacks or function as forward sensors.
The operating versatility spreads to carrier operations, the UCAS being designed for catapult takeoffs, arrested landings, and even folding wings for deck stowage. Air refueling capability will allow Rafale and UCAS to perform missions out to more than 1,000 nautical miles from home base. French authorities have mentioned that the UCAS will form the centerpiece of restoring a strong SEAD capability by 2030, supplementing the Rafale’s own increased strike envelope.
France is counterbalanced by infrastructure investments. A €1.5 billion expansion of Luxeuil‑Saint‑Sauveur Air Base will double its staff to 2,000 and make it the initial operational base for the Rafale F5 and ASN4G. Luxeuil will return to the nuclear deterrent network and continue NATO air policing, underlining the F5’s dual capability in strategic and conventional missions.
In the world fighter market, Dassault is marketing the Rafale F5 as a sovereign alternative to the F‑35, especially for countries that want cutting-edge capability without U.S. export restrictions. Whereas Lockheed Martin is plotting its own F‑35 upgrades CEO Jim Taiclet compared them to making the jet “a Ferrari” the Rafale F5’s combination of hypersonic strike, loyal wingman integration, and propulsion breakthroughs is a distinctly European conception of sixth‑generation combat power.
