France's Directorate General of Armaments awarded MBDA a development contract for the ASN4G, a fourth-generation hypersonic air-to-surface nuclear cruise missile. The weapon will equip the upgraded Rafale F5 fighter and enter service around 2035 to replace legacy ASMPA-R stocks.
What's happening
- The DGA awarded MBDA the ASN4G development contract and implementation framework agreement on June 2, 2026.
- ASN4G is designed to operate at speeds exceeding Mach 5 with active mid-flight maneuverability to penetrate advanced air defenses.
- The missile will equip both the French Air and Space Force's Strategic Air Forces and the French Navy's Nuclear Naval Aviation Force.
- Rafale F5 qualification is targeted for around 2033, with ASN4G operational service entry planned for around 2035.
Why it matters
- ASN4G renewal sustains France's visible, recallable airborne nuclear strike capability alongside its submarine-launched ballistic missile fleet.
- Hypersonic speed and maneuverability compress enemy response timelines and complicate air defense prediction, preserving penetration probability against sophisticated surface-to-air systems.
- The program requires integrated modernization of the Rafale platform, including new radar, electronic warfare systems, optronic sensors and enhanced connectivity.
- France's nuclear deterrent relies on pairing an advanced missile with an aircraft capable of surviving the approach to launch position.
Going deeper
- Rafale F5 includes development of a stealth combat drone to support contested airspace missions, including potential enemy air defense suppression.
- DGA awarded preparatory contracts to Dassault Aviation, MBDA, Safran and Thales in September 2026 ahead of the planned F5 implementation phase launch at year-end.
- ASN4G replaces the current ASMPA-R missile across both land-based and carrier-based French nuclear aviation.
- The program remains in development; maximum speed, range, missile mass and warhead yield remain undisclosed.
The fine print
- Contract value and specific technical specifications remain undisclosed.
- Stated program objectives should be distinguished from demonstrated operational performance.
- Integration requires separate development paths for the Rafale F5 and ASN4G, with qualification milestones staggered between 2033 and 2035.
