It was about 1938 when the U.S. Army put out a request for a medium bomber that would fill the gap between its light and heavy bombing aircraft. North American came up with the NA-40 that eventually became the B-25 bomber, known as the Mitchell.
The B-25 bomber went on to become a primary medium bombing aircraft of World War II. Production aircraft first flew in 1940 and were deployed to the U.S. Army Air Force in 1941. They remained deployed throughout the War. B-25 aircraft first saw action in January of 1942 when they sunk a Japanese submarine off the coast of Washington.
Perhaps the B-25 bomber is best remembered as the bomber that carried out the “Doolittle Raid” over Tokyo on April 18, 1942. A total 16 B-25 aircraft, led by then Lt. Colonel “Jimmy” Doolittle took off from the U.S. aircraft carrier Hornet to bomb Tokyo in retaliation for the Pearl Harbor attack.
The B-25 bomber aircraft flew just above the waves, some 650 miles to Japan. The mission began about 10 hours earlier and was about 195 miles longer than planned. The USS Hornet was spotted by a Japanese picket boat that radioed a warning prior to its being sunk. As a precaution the B-25 bombers launched early. However, it appears that the transmission was never received.
None of the B-25 bomber aircraft were damaged over Japan and all were able to drop their bombs. The light bomb loads and small number of aircraft caused minimal damage. It did, however, prove that Japan could be reached by United States aircraft. Upon completion of the bombing, a total of fifteen aircraft turned for Chinese air fields, while a single aircraft tried to reach Russia.
The fifteen B-25 bomber aircraft ran out of fuel before making it to friendly air fields and made forced landings. Three bomber crews perished. Eight crewmen were captured by the Japanese of which three were executed. The other crews were aided by the Chinese. The remaining B-25 bomber reached Russia where it landed, with the crew being interned and aircraft confiscated. Fourteen crews eventually made it back to American Forces with the exception of one crew member who chose to remain in the Soviet Union.
The medium bomber was named after General Billy Mitchell, one of the earliest proponents of air power. Its pilots appreciated the aircraft for its predictable handling, and ground crews appreciated its low maintenance.
The B-25 bomber, produced by North American Aircraft, was their first mass manufactured warplane. Its design made it relatively easy to produce and simple to maintain.
One of the most versatile U. S. aircraft of World War II, its missions included strafing, low and medium altitude bombing, training, anti-shipping, and reconnaissance.
B-25 bomber maneuverability is surprisingly nimble for a larger aircraft. It is possible to fly it more like a fighter than a bomber. Yet it is best to keep up moderate speed until after turning on to final because the aircraft responds very slowly to control inputs at lower speeds. Flying in a restored B-25 bomber is an adventure. The sound of its twin radial engines is music to the ears, and being able to fly in the warbird is a thrill.
The B-25 bomber models C and D were much improved over their predecessors. The C models were produced in Inglewood, California, while the D models were produced in Dallas, Texas.
Over 3,900 B-25 bomber C and D models were built. Some 530 of the aircraft were exported to Great Britain for use by the Royal Air Force. A total of over 800 B-25 bomber aircraft were eventually acquired by Great Britain under the “Lend-Lease Act”. About 870 B-25 C and D models were also exported to the Soviet Union.
B-25 bomber aircraft first entered RAF service with 98 and 180 Squadrons in September of 1942. The aircraft were assigned to the Second Tactical Air Force in August of 1943. They flew sorties into Northern France to soften enemy positions for “D-Day” landings. Other B-25 bomber aircraft raided V-1 sites in France.
The B-25 bomber model G was a descendant of the C model. Over 400 of the aircraft were produced, fitted with a 75 mm cannon in the nose. Model G aircraft were used for ground attack and anti-shipping.
Over 1,000 B-25 bomber model H aircraft were produced. They were used primarily in the Pacific. They were equipped with a lighter, quicker firing 75mm cannon. They also carried four .50 cal. machine guns in the nose and an additional four .50 cal machine guns in blisters, with two on each side of the nose. Pairs of .50 cal. machine guns were also located in the waist, dorsal turret, and tail. A typical bomb load was around 3,000 lbs. Up to eight rockets could be carried under its wings.
About 4,300 model J B-25 bomber aircraft were produced, more than any other model. They retained the armament and ordnance of the model H, but without the 75mm cannon. These aircraft were deployed by the U.S. and Great Britain throughout the Mediterranean, the Pacific, and South East Asia.
The United States Marine Corps. began deploying the B-25 bomber starting in January of 1943. By the end of the war, the Marines had about 700 of the aircraft. Their primary mission was to support the U.S.M.C. ground troops against Japanese troops while they landed on Pacific Islands.
During World War II the B-25 bomber was deployed by the air forces of Australia, Canada, China, France, Great Britain, the Netherlands, and the United States. Demand by U.S. Allies for the airplane was so great that U.S. forces never had more than about 2,700 B-25 bomber aircraft deployed at any one time.
When World War II ended, the B-25 was used primarily as a trainer. Flight schools appreciated the easy ground handling of the aircraft due to its wide spread main landing gear and steady in-flight handling. The steady flight characteristics made them a favorite camera ship for movie producers. Some post-war aircraft were used by the U.S. military as VIP transports until they were eventually retired in May of 1960.
Over 9,950 of the B-25 bomber aircraft were built by North American. It is estimated that some forty are still flying today, with about another 50 on display throughout the United States and around the world in museums.
