The Type 1940 torpedo boats were a group of 24 torpedo boats that were intended to be built for Germany's Kriegsmarine during World War II. Although classed as fleet torpedo boats (Flottentorpedoboot) by the Germans, they were comparable to contemporary large destroyers. They were designed around surplus Dutch propulsion machinery available after the Germans conquered the Netherlands in May 1940 and were to be built in Dutch shipyards. Hampered by uncooperative Dutch workers and material shortages, none of the ships were completed before the Allies invaded Normandy (Operation Neptune) in June 1944. The Germans towed the three ships that were most complete to Germany to be finished, but one was sunk en route by Allied fighter-bombers and no further work was done of the pair that did arrive successfully. The remaining ships in the Netherlands were later broken up for scrap and the two that reached Germany were scuttled in 1946.
