The SNLE 3G (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.[2]
