 In April 1942, Adolf Hitler made the production of aerial torpedoes a German priority, and the "Luftwaffe" took the task over from the "Kriegsmarine".The quantity of available aerial torpedoes outstripped usage within a year, and an excess of aerial torpedoes was on hand at the end of the war.From 1942 to late 1944, about 4,000 aerial torpedoes were used, but some 10,000 were manufactured during the whole war.
