BACKGROUND & OBJECTIVES
Barracuda, the second generation of French SNA
Nuclear-powered attack submarines (SNA), based in Toulon, are designed for naval combat, the protection of the French aircraft carrier, and intelligence gathering. These submarines, which are larger than the Rubis-class SNA submarines they are replacing, are among the most compact in the world. They are scheduled to remain in service through the 2060s.
our role
6 onboard nuclear reactors
TechnicAtome is the prime contractor responsible for the design and construction of the nuclear reactors for the six attack submarines in the series. These submarines are equipped with an onboard nuclear reactor that offers ever-increasing availability, power capacity, and nuclear safety.
