in 1943 the Luftwaffe was not in real fear of the combined RAF/US heavy bomber fleets. The Luftaffe could still deal huge blows and shown throughn history. On;ly through the immense and long battles on early 1944 into spring of that year did the Luftwaffe feel that the time was ripe for new projected wepaons to be released and tested on the Allied formations.......too late !
