Vendémiaire was a Pluviôse-class submarine built for the French Navy (Marine Nationale) in the late 1900s. She was sunk with all hands when she was rammed by the pre-dreadnought battleship Saint Louis on 8 June 1912 while on maneuvers off the Casquets in the English Channel.

Design and description
The Pluviôse class were built as part of the French Navy's 1905 building program to a double-hull design by Maxime Laubeuf.[1] The submarines displaced 404 metric tons (398 long tons) surfaced and 553 metric tons (544 long tons) submerged. They had an overall length of 51.12 meters (167 ft 9 in), a beam of 4.96 meters (16 ft 3 in), and a draft of 3.15 meters (10 ft 4 in). Their crew numbered 2 officers and 23 enlisted men.[2]
For surface running, the boats were powered by two 350-metric-horsepower (345 bhp; 257 kW) triple-expansion steam engines, each driving one propeller shaft using steam provided by two Du Temple boilers. When submerged each propeller was driven by a 230-metric-horsepower (227 bhp; 169 kW) electric motor.[3] On the surface they were designed to reach a maximum speed of 12 knots (22 km/h; 14 mph) and 8 knots (15 km/h; 9.2 mph) underwater.[1] The submarines had a surface endurance of 865 nautical miles (1,602 km; 995 mi) at 11.6 knots (21.5 km/h; 13.3 mph) and a submerged endurance of 70 nmi (130 km; 81 mi) at 2.8 knots (5.2 km/h; 3.2 mph).[4]
The first six boats completed were armed with a single 450-millimeter (17.7 in) internal bow torpedo tube; Vendémiare had one fitted in early 1910 while she was still under construction. All of the boats were fitted with six 450 mm external torpedo launchers; the pair firing forward were fixed outwards at an angle of seven degrees and the rear pair had an angle of five degrees. Following a ministerial order on 22 February 1910, the aft tubes were reversed so they too fired forward, but at an angle of eight degrees. The other launchers were a rotating pair of Drzewiecki drop collars in a single mount positioned on top of the hull at the stern. They could traverse 150 degrees to each side of the boat. The Pluviôse-class submarines carried eight torpedoes.[5]
Construction and career
Vendémiaire, named after the first month of the French Republican calendar, was ordered on 26 August 1905 from the Arsenal de Cherbourg. The submarine was laid down in 1906, launched on 7 July 1910 and commissioned on 4 February 1911.[6]
Vendémiaire sank with the loss of her entire crew of 24 on 8 June 1912 after colliding with the battleship Saint Louis in the English Channel off the Casquets during maneuvers.[7][8]
