thingiverse

Surcouf was the largest French submarine cruiser ever built, serving in both the French Navy and the Free French Naval Forces during World War II. She disappeared on February 19, 1942, possibly after colliding with an American freighter in the Caribbean Sea. The Surcouf was named after Robert Surcouf, a famous French privateer. She was the largest submarine built until the Japanese I-400-class submarine surpassed her in 1943.
