Design

The Lagrange class submarines were constructed as part of the French fleet's expansion programmes from 1913 to 1914. [1] [2] The ships were designed by Julien Hutter, slightly modifying his previous project Dupuy de Lôme, using two Parsons steam turbines with a power of 2,000 hp (1,491 kW). [3] During construction, though, the idea was abandoned and the ships were instead equipped with diesel engines. [1] [3]

75.2 m (246 ft 9 in) long, with a beam of 6.3 m (20 ft 8 in) and a draught of 3.6 m (11 ft 10 in), [1] [4] Lagrange-class submarines could dive up to 50 m (160 ft). The submarine had a surfaced displacement of 920 tonnes (905 long tons ) and a submerged displacement of 1,318 tonnes (1,297 long tons ). [1] [4] Propulsion while surfaced was provided by two 2,600 hp (1,939 kW) diesel motors built by the Swiss manufacturer Sulzer and two 1,640 hp (1,223 kW) electric motors. [5] [3] The submarines' electrical propulsion allowed it to attain speeds of 11 knots (20 km/h; 13 mph) while submerged and 16.5 knots (30.6 km/h; 19.0 mph) on the surface. [3] [4] 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). [1] [3]

The ships were equipped with eight 450 mm torpedo tubes (four in the bow, two stern and two external), with a total of 10 torpedoes and two on-board guns. [5] [3] The class was also armed with a 75 mm with an ammo supply of 440 shells. The crew of one ship consisted of four officers and 43 of officers and seamen. [5] [3] [6]

Service history

Romazotti was built in the Arsenal de Toulon. [7] [8] It was laid down in 1914, launched on 31 March 1918, [7] [3] and completed in 1918. It was named in honor of the distinguished French nineteenth-century naval engineer Gaston Romazotti.[ citation needed ]Romazotti served in the Mediterranean Sea until 1937. [1] [7]
