While not the winning submission, nevertheless, the USAAC issued a production order on 20 September 1939 for the type. The prototype performed its maiden flight on 19 August 1940; shortly thereafter, a redesigned gull wing was adopted to correct a tendency to Dutch roll. The B-25 was a relatively forgiving aircraft to fly and durable under fire.
The B-25 entered service with the United States Army Air Forces (USAAF) in early 1941. Produced throughout World War II, numerous variants of the type were used operationally, contributing to nearly 10,000 B-25s being built. It was the most-produced American medium bomber and the third-most-produced American bomber overall. These included several limited models such as the F-10 reconnaissance aircraft...
