The order for the production of 100 boats – U 4501 to U 4600 – was first placed on May 6, 1944, at the Schichau shipyard in Danzig, who already had relevant experience with the construction of sections through the production of the Type XXI boats. The amount of crude steel required for the hundred boats was estimated at 46,240 t.
During World War II, Nazi Germany's Kriegsmarine considered various submarine designs for specialized operations or improving U-boat performance. Many of these designs did not come to fruition for various reasons; some were abandoned due to practical considerations, while others towards the end of the war had to be abandoned as the yards where they were being built were overrun by allied forces.
German submarine U-451 was a Type VIIC U-boat in the service of Nazi Germany's Kriegsmarine during World War II.. Commissioned on 3 May 1941, with Korvettenkapitän Eberhard Hoffmann in command, she was assigned from then until 1 July to the 3rd U-boat Flotilla for training, and from 1 July 1941 until 21 December, she remained with the 3rd flotilla for operations.
German submarine U-2501 was a Type XXI U-boat (one of the "Elektroboote") of Nazi Germany's Kriegsmarine, built for service in World War II.The submarine was laid down on 3 April 1944 at the Blohm & Voss yard at Hamburg, launched on 12 May 1944, and commissioned on 27 June 1944 under the command of Oberleutnant zur See Otto Hübschen, who commanded her for her entire career.
Constructed at the docks of Hamburg, Germany, the U-505 was one of the German navy's Type IX-class submarines, a long-range attack boat developed with longer dive times and agility compared to its ...
The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use ...
The submarine was commissioned as a research vessel in the Bundesmarine, serving from 1 September 1960 until 28 August 1968 as a test boat (class 241). On relaunch she was renamed Wilhelm Bauer, after the designer of the first German U-boat, Brandtaucher, built in Kiel by August Howaldt in 1850.
Prototype "fleet submarines"—submarines fast enough (21 knots (11 m/s)) to travel with battleships. Twice the size of any concurrent or past U.S. submarine. A poor tandem engine design caused the boats to be decommissioned by 1923 and scrapped in 1930.
