- On January 25, 1939, the Army Air Corps announced a competition for a
medium bomber design, but instead of waiting for the prototypes, the Army
awarded production contracts to North American for the B-25 and Martin for the
B-26.
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. The 17th Bomb
Group at McChord Field, Wash., was the first unit to receive B-25s in 1941. On
April 18, 1942, Lt. Col. James H. "Jimmy" Doolittle led the Doolittle Raid, in
which 16 B-25B crews took off from the aircraft carrier USS Hornet (CV-8) and
bombed Tokyo and other targets, the first time US aircraft had bombed Japan.
The 75-mm cannon in the B-25G/H was used with mixed results, primarily against
ships. Recoil from the cannon was 21 inches and momentarily stopped the plane
in flight. The Marine Corps received 706 B-25Bs, Cs, and Ds, which were
redesignated PBJ-1, and used for antisubmarine patrol duties. Mitchells were
later relegated to support duties and did not see service in Korea. The last
B-25s were used to train pilots assigned to fly bombers and tankers. Large
numbers of B-25s were flown by the Soviet Union and Britain. It was also flown
by the Netherlands, Taiwan, and Brazil. A number of surplus B-25s were used by
civilian operators as aerial camera ships for Hollywood movies. On May 21,
1960, the last serving aircraft, a VB-25J staff transport, was retired from
service at Eglin AFB, Fla.
