German submarine U-752 was a Type VIIC U-boat built for the German Kriegsmarine for service during World War II. She served with 3rd U-boat Flotilla from 24 May 1941 to 23 May 1943 under the command of Karl-Ernst Schroeter.[1] U-752 completed nine[2] wartime patrols and sank eight ships totalling 33,492 GRT, and damaged one for a total of 4,799 GRT.

Thirty-two days into her ninth patrol, on 23 May 1943, U-752 was attacked by Fairey Swordfish aircraft attached to the British escort carrier HMS Archer in the mid-Atlantic. A Rocket Spear, a new weapon with a solid cast iron head,[3] entered and left the pressure hull leaving large holes, and the U-boat went down with twenty-nine crew members, including her commander. Of the forty-six crewmen aboard, seventeen survived the sinking. This was the first success of the Rocket Spear.
