, launched on 22 September 1941, and commissioned on 8 December 1941 under the command of Kapitänleutnant Friedrich Steinhoff.
After training with 4th U-boat Flotilla, from May 1942 U-511 was used for testing the possibility of launching Wurfkörper 42 30 cm (11.8 in) artillery rockets from U-boats. A rack of six rockets were mounted on deck, and were successfully launched while on the surface and while submerged up to a depth of 12 metres (39.4 ft). However, the rockets were not particularly accurate, and the racks on the deck had a negative effect on the U-boat's underwater handling and performance, so the project was abandoned.
The U-boat was attached to 10th U-boat Flotilla for front-line service on 1 September 1943. In that role she carried out four war patrols, two commanded by Kptlt. Steinhoff, and two by Kptlt. Fritz Schneewind, sinking five ships totalling and damaging one of .
