Sané was one of two s built for the French Navy during World War I. She played a minor role in the war and was sold for scrap in 1938.

Design and description The Dupuy de Lôme class were built to satisfy a requirement for steam-powered, high-speed submarines. They displaced surfaced and submerged. The boats had an overall length of , a beam of , and a draft of . Their crew numbered 41 officers and crewmen.Roberts, p. 452

For surface running, the Dupuy de Lôme-class boats were powered by a pair of three-cylinder vertical triple-expansion steam engines, each driving one propeller shaft using steam provided by two oil-fired du Temple boilers. The engines were designed to produce a total of to give a speed of , but during Sanés sea trials on 20 April 1916, she only reached . When submerged each shaft was driven by a electric motor.Smigielski, p. 211 The designed speed underwater was , but Sané only reached during her trials. The boat demonstrated a surface endurance of at and a submerged endurance of at .

The Dupuy de Lôme class was armed with a total of eight torpedoes. Two internal torpedo tubes in the bow angled outwards three degrees. Four more were located in four external rotating launchers amidships, two on each broadside; one pair each fore and aft of the conning tower that could traverse 143 degrees to the side of the boats. The last pair were in external tubes in the stern aimed outboard at an angle of seven and a half degrees. While the boats were under construction, a anti-aircraft (AA) gun was ordered to be installed in August 1915, but this was ordered to be replaced by a light gun later that year. Another 75 mm gun was added to the boats in an order dated April 1916. Sané had her forward 75 mm gun replaced by a gun in 1917.Garier 2000, pp. 106–107

Construction and career Sané was laid down by the Arsenal de Toulon on 29 December 1913, launched on 27 January 1916 and commissioned in September 1916. She was condemned on 27 August 1935, and sold for scrap on 6 August 1938.
