Suffren-class submarine

The Suffren-class submarine is France's Barracuda-class nuclear-powered attack submarine family built by Naval Group for the French Navy. The class is intended to replace the Rubis-class boats and combines hybrid propulsion, optronic masts, a dry deck shelter option, and a weapons fit that includes MdCN naval cruise missiles, F21 torpedoes, SM39 missiles, and mines.

Launched Weapons

The class's fitted weapons give it long-range strike and conventional undersea attack options.
