SURCOUF (submarine)
The Surcouf was a one-of-a-kind submarine. It was known as “submarine cruiser” due to the installation of two 203mm naval guns. Although the concept of this type of ship was of German origin, it was the French with this submarine, and the British with the “M” class boats, who carried it out. The Surcouf‘s main mission was to destroy single-sailing merchant ships and the pursuit of enemy convoys. The French Navy designated this ship as a “corsair submarine” and although they believed that a submarine armed with powerful guns capable of sinking merchant ships from a long distance seemed the right thing to do, in the case of the Surcouf it was not.
