Daytime bomber raids on Germany cause problem very quickly for allies, the fuel autonomy of aircraft…Not for the bombers but for the escort made up of fighters.
Indeed the bombers are vulnerable to barrage from the German Flak and its fighters who must intercept the bombers at all costs., the losses are enormous. A permanent escort of the bomber formations is therefore needed..
These raids with escort are therefore limited by the range of action of the hunters and can only operate in the heart of Germany from November. 1943 with the Lockheed P38 Lightning.
December 1943, the high-performance North America P-51 Mustang and its radius of action of more than 1000 kilometers will provide the solution to this problem.
