German submarine U-672

German submarine U-672 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 24 December 1941 at the Howaldtswerke yard at Hamburg, launched on 27 February 1943, and commissioned on 6 April 1943 under the command of Oberleutnant zur See Ulf Lawaetz.

Attached to 5th U-boat Flotilla based at Kiel, U-672 completed her training period on 30 September 1943 and was assigned to front-line service.

Service history
On the fourth and final war patrol, U-672 was attacked by the British frigate HMS Balfour north of Guernsey and heavily damaged on 18 July 1944. Forced to surface, the crew abandoned ship and scuttled the U-boat. All 52 crew members survived and were picked up the next day by British life-boats.
