I must say that during the war .. there simply wasnt much need for rockets like a v1 or v2... its not that america or the british didnt have any expertise in it.. but the the payloads and effective range just were not that useful..
once you could do the R&D to make long range missiles and have payloads that were really destructive then its a different story for bang for the buck.. precision bombing was much more effective and carpet bombing much more scary then just a few missiles falling from the sky.
Whats gogin to be more effective? 200 bombers or 10 missiles? i'm gogin for the bombers with the ordinence of the time..
