L’INFLEXIBLE
The S-615 L’Inflexible submarine was the last built within the Le Redoubtable SSBN class, which were France’s first nuclear powered ballistic missile submarines. However, this submarine was designed to carry the new M-4 submarine launched ballistic missiles (SLBM), larger and superior in range and performance to the M-2 and M-20 SLBM missiles in service. Because of this and because it incorporated the most modern electronics, L’Inflexible boat was considered a class on its own.
