While Germany continued construction works on the two destroyers, neither were completed, with one sunk by sabotage in 1944 and the other by British bombers in 1945.

[3][4] 300 long tons (300 t) of oil could be carried, giving a range of 3,100 nautical miles (5,700 km; 3,600 mi) at 19 knots (35 km/h; 22 mph).

[3][4] The two as-yet unnamed destroyers[c] were laid down in April 1939 at the naval dockyard at Horten,[3] with completion planned for 1943.

[1] They were still at an early stage of construction when Germany invaded Norway in April 1940, and were captured when German forces seized Horten.

[5][6][10] After the end of the war in Europe in 1945, the wreck of TA8 was raised by the Norwegians, who decided to complete the ship with the name Ålesund,[5][6] but work was abandoned in 1950 and the hulk sold for scrap in 1956.
