French submarine Gymnote (Q1)

Gymnote was one of the world's first all-electric submarines and the first functional submarine equipped with torpedoes.

Launched on 24 September 1888, she was developed in France following early experiments by Henri Dupuy de Lôme, and, after his death, by Gustave Zédé (1825–1891) and Arthur Krebs, who completed the project. For Gymnote, Arthur Krebs developed the electric engine, the first naval periscope and the first naval electric gyrocompass. The name "Gymnote" is French for Gymnotidae.
