English: Surcouf was a French Navy submarine ordered to be built in December 1927, launched on October 18, 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 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.
