Project history

L'Inflexible, the sixth boat, was an intermediate design between the Le Redoutable class and the new-generation SNLE of the Le Triomphant class, and incorporated a number of improvements. She was fitted from the outset to fire the M-4 missile, which carried six TN-70 150kt MlRVs out to a range of 4000km. She also had the new DSUX-21 multifunction sonar array, DUUX-5 passive ranging, a DSUV-61 towed array, and improved inertial navigation systems. The diving planes were mounted higher on a more streamlined fin, and diving depth had been increased from 200m to 300m. Considerable attention was given to reducing noise emissions.
