Surcouf was a French submarine ordered to be built in December 1927, launched on 18 October 1929, and commissioned in May 1934. Surcouf – named after the French privateer Robert Surcouf – was the largest submarine ever built until surpassed by the first Japanese I-400-class submarine in 1943. Her short wartime career was marked with controversy and conspiracy theories. She was classified as an “undersea cruiser” by sources of her time.
