" At the end of April 1944, a bomber attack to Friedrichshafen revealed the German tank industry´s vulnerability. Factories in Friedrichshafen produced 40 to 50% of the drive gear assemblies for the Pz III,IV and V tanks; 40% of motors for Pz V´s and VI´s. The works, badly damaged by the attack took at least two to three months to disperse to other factories. Thus, there was a production shortfall of at least 30% for May and June 1944.
