Mitchell bombers participated in campaigns in the Solomon Islands, Aleutian Islands, Papua New Guinea, and New Britain, among others. Owing to the tropical nature of the environment, mid-level bombing was less efficient, and thus the B-25s were adapted to serve as low-altitude attack bombers.
During the Southwest Pacific campaigns, the B-25 enormously contributed to Allied victories as the 5th Air Force devastated the Japanese forces through skip-bombing attacks on ships and Japanese airfields.
In the China-Burma-India theater of the war, B-25s were widely used for interdiction, close air support, and battlefield isolation.
The B-25’s extraordinary capabilities as a bomber were first brought to the limelight following their performance in the Tokyo Raid of 18 April 1942, in which the hitherto impregnable home islands of Japan were attacked.
