The construction of the first of four third-generation nuclear ballistic submarines (SNLEs), which, starting in 2035, will embody the oceanic component of France’s nuclear deterrent force, began on Wednesday with the symbolic cutting of the first sheet of metal in Cherbourg, the defense ministry said, citing AFP.

The aim is to replace the Le Triomphant-class nuclear-powered ballistic submarines (SNLEs) in service and launched between 1994 and 2008, hence their name “SNLE 3G”, for the third generation since the first launched by France in 1967.

According to the ministry, in February 2021, a contract worth “several billion euros” was signed for the “general design” stage of these underwater vehicles.

According to Naval Group, the contract covers “development studies until the end of 2025, long-term procurement, production of the first hull and boiler components for the first SNLE 3G, and the adaptation of Naval Group’s industrial production resources to the specific requirements of SNLE 3G.”

Only in 2024, approximately 634 million euros have been allocated for this program. More than 400 companies are participating, representing 3,000 direct jobs, according to Naval Group.

France sees deterrence as insurance against threats to its existential interests.

France’s SNLEs, of which there are four, so one is always on patrol, are the backbone of the nuclear strategy, along with two squadrons of Rafale fighter jets capable of carrying the ASMP-A nuclear missile.

According to the ministry, the 3G SNLEs will carry “future versions of the M51 strategic missile.”
