The M-4 generation of ballistic missiles, developed and produced by Astrium for the ballistic missile systems in France’s nuclear deterrent force, features multiple warheads and a range of more than 4,000 kilometres. They were incrementally deployed on the first-generation of nuclear-powered ballistic missile submarines (SNLEs) from 1985, taking over from the previous M-20 missiles.
Astrium also developed an enhanced version, the M-45, with higher-performance TN75 nuclear warheads (stealthier and with penetration aids). The M-45 entered service aboard Le Triomphant in spring 1997.
M-4/M-45 through-life support: Astrium's role
As prime contractor for the ballistic missile systems of the French Ministry of Defence armaments procurement agency DGA, Astrium is also responsible for the development and manufacture of the weapon systems and weapon deployment systems, covering analysis of technical events occurring in service at the maritime base and onboard SNLEs, system design support and examination of engineering changes, user technical assistance, preparation and analysis of missile launch acceptance.
