The P-51 was
designed as the NA-73 in 1940 at Britain's request. The design
showed promise and AAF purchases of Allison-powered Mustangs
began in 1941 primarily for photo recon and ground support use
due to its limited high-altitude performance. But in 1942,
tests of P-51s using the British Rolls-Royce "Merlin" engine
revealed much improved speed and service ceiling, and in Dec.
1943, Merlin-powered P-51Bs first entered combat over Europe.
Providing high-altitude escort to B-17s and B-24s, they scored
heavily over German interceptors and by war's end, P-51s had
destroyed 4,950 enemy aircraft in the air, more than any other
fighter in Europe.
