Luftschiffbau Zeppelin stopped manufacturing in 1938 and operations by 1940. In the autumn of 1941, the company had accepted contracts to produce V-2 rocket propellant tanks and fuselage sections.[4] By 17 August 1942, the Allies had suspected that the Zeppelin Works in Friedrichshafen (as well as the Henschel Raxwerke) were involved with the V-2 rocket,[5] and on 25 July 1943, Duncan Sandys reported[to whom?] that Friedrichshafen photos depicted rocket firing sites like Test Stand VII at Peenemünde.[citation needed] Previously in June 1943, Allied bombing during Operation Bellicose had hit the Zeppelin V-2 facility, and production was subsequently moved to the Mittelwerk.
