What is the B-25 aircraft?
The B-25, a U.S. medium bomber used in World War II, was designed by North American Aviation, Inc. in response to a prewar requirement, with the first flight in 1940. It is a high-wing monoplane with a twin tail and tricycle landing gear, powered by two 1,700-horsepower Wright radial engines. The B-25 had a range of 1,350 miles, a maximum speed of about 300 miles per hour, and a ceiling of 24,000 feet. It could carry 3,000 pounds of bombs.
About 9,800 B-25s were produced and used in all theaters of the war by the U.S., British Royal Air Force, and the Soviet Red Air Force. The B-25's most spectacular exploit was the April 18, 1942, bombing raid on Tokyo led by Lieutenant Colonel James Doolittle.

How was the B-25 used in World War II?
The B-25, a U.S. medium bomber, served in every theater of World War II with the U.S. Army Air Forces, the British Royal Air Force, and the Soviet Red Air Force.
The B-25 saw action in the Mediterranean and Pacific theaters. Its most noteworthy mission was the April 18, 1942, Doolittle Raid on Tokyo, where B-25s launched from the USS Hornet, which was unprecedented for medium bombers. In the Southwest Pacific, the 5th Air Force used it to skip-bomb Japanese ships and drop fragmentation bombs via parachute on Japanese airfields with devastating results.
The B-25 proved easy to maintain in primitive field conditions and was a pleasant aircraft to fly. The Air Force used it as a liaison aircraft and light transport into the mid-1950s.

Why is the B-25 famous in military history?
The B-25, a U.S. medium bomber from World War II, achieved military fame through its versatility and impact in various theaters. Its most notable exploit was the Doolittle Raid on April 18, 1942, where it was launched from the USS Hornet to bomb Tokyo, a feat never before accomplished by a medium bomber. Beyond this morale-boosting raid, the B-25 significantly contributed to Allied victory in the Southwest Pacific through skip-bombing attacks on Japanese shipping and airfield bombardments. Its ease of maintenance in primitive conditions further solidified its importance in the Pacific theater.

B-25, U.S. medium bomber used during World War II. The B-25 was designed by North American Aviation, Inc., in response to a prewar requirement and was first flown in 1940. A high-wing monoplane with a twin tail and tricycle landing gear, it was powered by two 1,700-horsepower Wright radial engines, had a wingspan of 67 feet 7 inches (20.6 metres), was 53 feet 6 inches (16.3 metres) long, and carried a crew of four to six. The B-25 had a range of 1,350 miles (2,175 km), a maximum speed of about 300 miles (480 km) per hour, and a ceiling of 24,000 feet (7,300 metres). It could carry 3,000 pounds (1,360 kg) of bombs internally in the bomb bay and more externally on underwing racks.
The B-25 was built in a number of versions with wide variations in offensive and defensive armament. The B-25B, the first version to see widespread combat, had turrets mounting twin 0.50-inch (12.7-mm) machine guns in the upper fuselage and belly. Both turrets were powered; in addition, the belly turret was retractable and was fired remotely by a gunner inside the fuselage. Though the B-25 was intended primarily for short-range daylight bombing missions, a considerable number had the Plexiglas nose for bomb aiming replaced with a “solid” nose mounting heavy forward-firing armament for ground strafing and for flak suppression during attacks on enemy shipping. In these cases the most common forward-firing armament was the 0.50-inch machine guns, eight being the typical number; however, the B-25H and G versions were armed with a 3-inch (75-mm) cannon plus four forward-firing machine guns. The final production version, the B-25J, had a larger internal bomb bay and no belly turret, but it had flexible manually operated single 0.50-inch guns in waist positions and four fixed forward-firing guns in external “package” mounts on the sides of the forward fuselage. The B-25J was built both with a transparent nose for bombing and with a solid nose mounting eight machine guns for strafing.
About 9,800 B-25s were produced during the war. They saw service in all theatres, though in larger numbers and to greater effect in the Mediterranean and Pacific. They were used by the British Royal Air Force and the Soviet Red Air Force as well as the U.S. Army Air Forces. The B-25’s most spectacular exploit was its use in the April 18, 1942, bombing raid on Tokyo led by Lieutenant Colonel (later Lieutenant General) James Doolittle. These planes were launched from the aircraft carrier USS Hornet, an unprecedented feat for medium bombers. The B-25’s most important contribution to Allied victory was in the Southwest Pacific area, where the 5th Air Force used it with devastating effect in skip-bombing attacks on Japanese shipping and to drop fragmentation bombs by parachute on Japanese airfields. The B-25 was a pleasant aircraft to fly and was easy to maintain under primitive field conditions, a significant factor in the Southwest Pacific. It was used by the Air Force as a liaison aircraft and as light transport into the mid-1950s.
