Design
Joessel was ordered in the French fleet's 1914 program as part of a two ship class. The ships were designed by Jean Simonot, as a modification of his previous project, Gustave Zédé, using two Parsons steam turbines with a power of 2,000 hp (1,491 kW). During construction, though, the idea was abandoned and the ships were instead equipped with diesel engines.[1][2][3]
The submarine had a surfaced displacement of 870 long tons (884 t) and a submerged displacement of 1,247 long tons (1,267 tonnes). The dimensions were 74 metres (242 feet 9 inches) long, with a beam of 6.4 m (21 ft 0 in) and a draught of 3.62 m (11 ft 11 in). She had two shafts powered by two diesel engines built by Schneider-Carels for surface running with a combined total of 2,700 hp (2,013 kW) and two electric motors which together produced 1,640 horsepower (1,220 kilowatts) for submerged propulsion. Her maximum speed was 16.5 knots (30.6 kilometres per hour; 19.0 miles per hour) on the surface and 11 knots (20 km/h; 13 mph) while submerged with a surfaced range of 4,300 nautical miles (8,000 kilometres; 4,900 miles) at 10 knots (19 km/h) and a submerged range of 125 nautical miles (232 km) at 5 knots (9.3 km/h). The boat's complement was 47 men.[1][Note 1][2][3]
Joessel was armed with eight 450 mm torpedo tubes (four in the bow, two stern and two external trainable mounts), with a total of 10 torpedoes and two 75 mm (3.0 in) guns.[1][2][3]
Service
Joessel was built in the Arsenal de Cherbourg.[2] She was laid down in November 1913,[1] launched on 21 July 1917,[2][3][Note 2] and completed in February 1920.[1] She received the pennant number Q 109.[2]
Joessel was refitted during the 1920s when she received a new conning tower, bridge and two periscopes of 7.5 m (at the conning tower) and 9.5 m (at Headquarters).[1][2][3]
Joessel served in the Atlantic until the early 1930s when she was transferred to Indochina.[3] She was stricken in May 1936.[1][2]
