The M45 SLBM is a French Navy submarine-launched ballistic missile (In French terminology, the MSBS - Mer-Sol-Ballistique-Stratégique (Sea-ground-Strategic ballistic missile).) Forty-eight M45 are in commission in the Force océanique stratégique, the submarine nuclear deterrent component of the French Navy.^{[needs update]} The missiles, derived from the M4, were produced by Aérospatiale (now EADS SPACE Transportation). Initially, an ICBM land-based version was considered, but these plans were discarded in 1996 to favour an all-naval deployment.

The M45 differs from its predecessor by its increased range (6,000 km vs. 4,000 km), its increased accuracy and penetration capabilities and its new TN-75 warheads. Each missile carries six MIRVs, each armed with a thermonuclear warhead of 110 kt.The M45 has a reported accuracy of 350 m CEP using an inertial missile guidance system coupled with computer payload control. It will be succeeded by the M51 SLBM.

Tests

In March 1986, a M-4 missile was launched and covered 6,000 km to its target; this flight is rumoured to have been the first test flight for the M-45.^{[citation needed]}

On the night of the 1–2 June 2004, the Triomphant-class submarine Vigilant fired a version of the M45 from the southern part of Brittany; the missile hit its target near French Guiana.
