The Invincible class (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.

The SNLE 3G submarines are expected to join the fleet from 2035 and remain in service until 2080-2090. The first steel will be cut for the vessels in March 2024 and completed submarines delivered at a rate of one every five years from 2035, with the program completing in 2050.
