Maurice Callot was a French Navy minelayer submarine commissioned in 1922, the first minelayer submarine designed and built in France. She was decommissioned in 1936.

Maurice Callot — originally named Pierre Callot — was named for the

Lieutenant de vaisseau Pierre Félix Maurice Callot, who perished when Pluviôse was sunk in a collision with the loss with all hands on 26 May 1910.[1]

Design

A

draft of 3.57 metres (11 ft 9 in).[2][3][4] Her surface displacement was 931 long tons (946 t), and her submerged displacement was 1,298 long tons (1,319 t).[2][3][4] She was propelled on the surface by two Schneider two-stroke diesel engines producing a combined 2,900 horsepower (2,163 kW).[2][3][4] Underwater propulsion was provided by two Schneider electric motors producing a combined 1,640 horsepower (1,223 kW).[2][3] The twin-propeller propulsion system made it possible to reach a speed of 16.5 knots (30.6 km/h; 19.0 mph) on the surface and 10.5 knots (19.4 km/h; 12.1 mph) when submerged.[2][3][4][5] She had a range of 2,800 nautical miles (5,190 km; 3,220 mi) at 11 knots (20 km/h; 13 mph) on the surface and 118 nautical miles (219 km; 136 mi) at 5 knots (9.3 km/h; 5.8 mph) underwater.[2][3]

Maurice Callot′s main armament consisted of 27 Sautter-Harlé 200-kilogram (441 lb)

trim.[6]

Rounding out Maurice Callot′s armament were six 450-millimetre (18 in)

officers and 45 petty officers and seamen.[2][3]

During Maurice Callot′s service life, her

minelaying system was modified, with the Laubeuf system being replaced by the Fernand Fenaux system, in which the mines were stored in wells placed in external ballast tanks, with a direct release mechanism.[3][7]

Construction and commissioning

Maurice Callot was ordered with the name Pierre Callot

laid down at Forges et Chantiers de la Gironde, in Lormont, France, in May 1917.[3][7] She was renamed Maurice Callot on 23 June 1920.[8] She was launched on either 26 March[3][7] or 23 June 1921,[2]
according to different sources.

During Maurice Callot′s

sea trials her port bow plane was torn off while she was at sea on 17 August 1921.[8] On 29 August 1921, her starboard bow plane also was torn off at sea.[8] She was completed in 1922.[7] She was commissioned either in 1922[7] or on 8 November 1923,[2] according to different sources. She had no Q-series pennant number.[3]

Service history

Maurice Callot spent her entire career in the Mediterranean Sea with the 3rd and 7th Submarine Squadrons.[9] On 19 December 1923, she again lost her port bow plane when it was torn off at sea.[8]

The 14 August 1925 edition of the magazine Engineering reported that Maurice Callot had "recently" completed a 50-day endurance test in the Mediterranean Sea.[6]

Maurice Callot suffered serious damage to her port diesel engine on 1 February 1926,[8] and the door of her No. 4 torpedo tube sustained damage while she was at sea on 19 February 1926.[8] One of her crewmen died on 24 June 1926, but sources do not describe the circumstances of his death.[2]

Disposal

Maurice Callot was placed in the "normal

decommissioned in 1936. She was condemned and stricken from the navy list on 28 January 1938[2] and sold at Toulon, France, on 24 November 1938[2]
for scrapping.
