France Advances Rafale F5 Fighter for First Entry Missions and Airborne Nuclear Strike Capability.

France has launched initial Rafale F5 development work to equip the fighter with a new radar, data links, electronic warfare systems, and increased engine thrust for contested-airspace operations. The programme will also prepare the aircraft for the ASN4G nuclear missile and collaborative missions with a future stealth combat drone.

Dassault Aviation, MBDA, Safran and Thales are developing key F5 systems including the RBE2-XG radar, IVDL communications link, digital SPECTRA suite and M88 T-REX engine with 20 percent more maximum thrust. At least 47 Rafales are planned to reach the F5 standard by 2035, with qualification expected around 2033 before service with the French Air and Space Force and French Navy.

The F5 standard goes beyond a conventional avionics upgrade. It will modify the aircraft architecture, particularly its mission system, to facilitate the integration of new sensors, weapons, and software. Dassault Aviation is notably working on a very-low-drift inertial navigation unit based on a hemispherical resonator gyroscope, or HRG. The system is intended to maintain accurate navigation when satellite signals are degraded, jammed or unavailable, a constraint that has become increasingly important in high-intensity air operations.

In a statement published on September 10, 2026, the French Defence Procurement Agency, or DGA, said the contracts had been awarded during the summer to reduce development risks before the F5 programme enters its full implementation phase. The DGA describes F5 as a major mid-life renovation focused on collaborative combat and the ability to conduct first-entry operations in hostile environments. The standard is expected to be qualified around 2033 before entering service with the French Air and Space Force and subsequently the French Navy.

Thales is developing the new Inter-Vehicle Data Link, or IVDL, based on a high-bandwidth waveform designed to remain discreet and resistant to jamming. It is intended to maintain tactical exchanges between aircraft in heavily contested areas. The Rafale F5 will also receive the RBE2-XG radar, an evolution of the current RBE2 AESA. Higher output power is expected to extend detection range and improve identification of targets with extremely low radar cross-sections. Processing capacity will also increase, allowing sensors to cooperate more extensively while reducing pilot involvement in some data-processing functions.

Electronic protection is being developed in parallel through the F5 upgrade of the SPECTRA self-protection suite by Thales and MBDA France. Its transition to a fully digital architecture is intended to improve detection and jamming against a denser electromagnetic spectrum and increasingly complex hostile waveforms. Safran is meanwhile developing the M88 T-REX, whose maximum thrust is planned to rise from 7.5 to 9 tonnes, an increase of 20 percent. The engine will retain the modular architecture and low fuel consumption of the M88-2 while providing additional margin for future systems and weapons.

The F5 programme is also taking shape within a more clearly defined force structure. By 2035, France plans to operate 225 combat aircraft, including at least 47 Rafales upgraded to the F5 standard. This figure applies to the overall French combat aircraft fleet and does not yet determine the precise allocation between the French Air and Space Force and the French Navy. The F5 is also expected to operate alongside a stealth combat drone drawing on technologies developed through the nEUROn demonstrator. Initial experimentation with accompanying drones is planned around 2028, followed by an operational demonstrator expected by approximately 2035.

The combination of the RBE2-XG, IVDL, SPECTRA F5, M88 T-REX and a combat drone gradually changes how the Rafale can be employed. The aircraft will be expected to detect some low-observable threats at greater distances, maintain communications under electronic attack, and distribute information to remote platforms. The accompanying drone could extend sensor coverage, complicate an opponent’s defensive picture or undertake missions involving greater exposure. F5 does not turn the Rafale into a structurally stealth aircraft, but its combat environment increasingly reflects a distributed architecture designed to operate inside heavily defended airspace.

This development has taken on additional importance following the end of the FCAS. Rafale F5 can sustain France’s high-end air combat capability beyond 2035, but it remains an extensive evolution of an existing airframe rather than a sixth-generation fighter. Paris must therefore prepare for the post-Rafale period as the United Kingdom, Italy and Japan move forward with GCAP for a planned 2035 entry into service, the United States develops the F-47 and the F-35 maintains a broad presence across European air forces. France now plans a national sixth-generation demonstrator while keeping the option of international partnerships open. Dassault is positioned to play a central role in such a programme, although this does not necessarily imply that development would be conducted by France alone. The challenge will be to retain national design capabilities and the technologies required to prevent a generational gap from emerging after the F5 as new American and European combat air systems enter service.
