French submarine Cigogne

Cigogne was the second of two Aigrette-class submarines built for the French Navy between 1903 and 1905. Laid down in May 1902, she was launched in November 1904 and commissioned in July 1906. She was an essentially experimental submarine, and although in service during World War I, saw no action. The class was designed by Maxime Laubeuf and used Drzewiecki drop collar launchers and external cradles to launch torpedoes.

Design
Cigogne had a surfaced displacement of 178 LT and a submerged displacement of 253 LT. Her dimensions were 35.9 m long, with a beam of 4.04 m and a draught of 2.63 m. She had a single shaft powered by one diesel engine for surface running of 150 hp and an electric motor which produced 130 hp for submerged propulsion. The maximum speed was 9.3 kn on the surface and 6.2 kn while submerged with a surfaced range of 1300 nmi at 8 kn and a submerged range of 65 nmi at 3.8 kn. Her complement was 14 men.

Construction and career
Cigogne was laid down on 13 May 1902, launched on 11 November 1904 and commissioned on 18 July 1906.

Cigogne was retired from service on 12 November 1919 and sold for scrap at Toulon on 14 April 1920.
