 The Germans, however, lost at least six fighters shot down by the bombers, a loss of 17-20% for the intercepting force, plus five or six more shot down away from the target area by prowling Beaufighters and Mosquitos of Fighter Command.The raid was later estimated to have delayed the V-2 rocket programme by two months.In the spring of 1944, the Air Ministry requested a further raid on Friedrichshafen, this time aimed at the tank engine and gearbox factories close to the Zeppelin shed.
