Design
78 m long, with a beam of 6.8 m and a draught of 5.1 m, Requin-class submarines could dive up to 80 m. The submarine had a surfaced displacement of 1150 LT and a submerged displacement of 1441 LT. Propulsion while surfaced was provided by two 2900 hp diesel motors and two 1800 hp electric motors. The submarines' electrical propulsion allowed it to attain speeds of 9 kn while submerged and 15 kn on the surface. Their surfaced range was 7700 nmi at 9 kn, and 4000 nmi at 12 kn, with a submerged range of 70 nmi at 5 kn.
