B-25A/B "Mitchell"
Attack aircraft
Douglas
 The North American B-25 Mitchell was an American designed twin-engined medium bomber, which was approved in September 1939,
Named in honor of US airpower proponent Brig. Gen. William "Billy" Mitchell, the B-25 served in every theater of World War II and was made in larger quantities than any other American twin-engine combat airplane.
As with all U.S. bombers in World War two, the development of the B-25 is marked by increasing armament, more armor, installation of self-sealing tanks, and, consequently, more weight. Until engines were correspondingly up-rated, performance inevitably suffered. Inadequate firepower in the nose and problems with gun turret installations, issues seen in many bombers, also challenged the Mitchell's designers.
The B-25A included pilot armor and self-sealing tanks. The B-25B introduced the notoriously unsuccesful Bendix ventral turret.
