Design

Y was 44.9 metres (147 feet 4 inches) long, with a beam of 3 m (9 ft 10 in) and a draught of 2.8 m (9 ft 2 in).[1][Note 1] The submarine had a surfaced displacement of 213 long tons (216 tonnes) and a submerged displacement of 226 long tons (230 tonnes).[1][Note 2] The submarine was powered by a 250 hp (186 kW) diesel engine for both surface and submerged running.[2][1] She had a maximum speed of 10 knots (19 km/h) on the surface and 6 knots (11 km/h) while submerged . She had a complement of 15 men.[1][2]

Her armament comprised two 450 mm (17.7 in) bow torpedo tubes, two 450 mm (17.7 in) Drzewiecki drop collar torpedo launchers and one external cradle aft 450 mm (17.7 in).[1][2]

Construction and career

Y was laid down in the Arsenal de Toulon, launched on 24 July 1905 and completed in 1906. Y was a single-hull diesel design by Louis-Émile Bertin. Y received the pennant number Q 37 and cost F924,300.[1]

Y was used for trials and experiments and never commissioned into the French Marine Nationale. In 1907, a reconstruction was proposed to install an electric motor and batteries for submerged running, but eventually the idea was abandoned.[2] Y was disarmed and stricken in May 1909.[1][2]
