Design

78 m (255 ft 11 in) long, with a beam of 6.8 m (22 ft 4 in) and a draught of 5.1 m (16 ft 9 in), Requin-class submarines could dive up to 80 m (260 ft). The submarine had a surfaced displacement of 1,150 tonnes (1,132 long tons) and a submerged displacement of 1,441 tonnes (1,418 long tons). Propulsion while surfaced was provided by two 2,900 hp (2,163 kW) diesel motors and two 1,800 hp (1,342 kW) electric motors. The submarines' electrical propulsion allowed it to attain speeds of 9 knots (17 km/h; 10 mph) while submerged and 15 knots (28 km/h; 17 mph) on the surface. Their surfaced range was 7,700 nautical miles (14,300 km) at 9 knots (17 km/h), and 4,000 nautical miles (7,400 km) at 12 knots (22 km/h), with a submerged range of 70 nautical miles (130 km) at 5 knots (9.3 km/h).[4][5]
