The Invincible class submarine (Sous-Marin Nucléaire Lanceur d'Engins de Troisieme Génération) "third generation nuclear ballistic missile submarine") is a class of submarines under development for the French Navy's nuclear deterrent, part of the Force de dissuasion. It is being designed as a replacement for the current Triomphant class beginning around 2035, and could remain in service to as late as 2090. Steel was cut on the first vessel in the class in March 2024. On 2 March 2026 President Emmanuel Macron announced that the lead vessel would be named Invincible and was planned to be in commission in 2036.
