Assessment
Unlike the V-2, the V-1 was a cost-effective weapon for the Germans as it forced the Allies to spend heavily on defensive measures and divert bombers from other targets. More than 25% of Combined Bomber Offensive's bombs in July and August 1944 were used against V-weapon sites, often ineffectively.[10] In early December 1944, American General Clayton Bissell wrote a paper which argued strongly in favour of the V-1 compared to conventional bombers.[32]
