German submarine U-673 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 20 January 1942 at the Howaldtswerke yard at Hamburg, launched on 27 February 1943, and commissioned on 8 May 1943 under the command of Oberleutnant zur See Gerhard Haelbich.

Attached to 5th U-boat Flotilla based at Kiel, U-673 completed her training period on 31 May 1944 and was assigned to front-line service.

Service history

On 14 September 1944, U-673 left St. Nazaire, France, for Norway, reaching Bergen on 19 October 1944. There the U-boat joined a convoy south. Early on 24 October 1944, U-673 collided with U-382 north of Stavanger and was beached at Smaaskjaer. Later the U-boat was salvaged and towed to Stavanger. U-673 remained in Stavanger for the rest of the war and became British war booty in 1945. In 1946 the U-boat was broken up for scrap.[2]
