To this day, I am convinced that substantial deployment of
Wasserfall from the spring of 1944 onward, together with an uncompromising use of the jet fighters as air defense interceptors, would have essentially stalled the Allied strategic bombing offensive against our industry. We would have well been able to do that -- after all, we managed to manufacture 900
V2 rockets per month at a later time when resources were already much more limited.
