The Mitsubishi "Babs" was known as the C5M when flown by the Navy and as the Ki-15 when flown by Army pilots. It was reliable but suffered from appalling forward visibility. Like most Japanese aircraft, it was fragile and lacked self-sealing fuel tanks, and its relatively low speed for a reconnaissance aircraft caused it to be withdrawn from service early in the war. However, it was a C5M2 out of French Indochina that spotted Force Z and sealed its fate.

The aircraft was well-known in the West even before war broke out, since the second prototype was sold to Asahi Shinbun for civilian use and set a speed record in April 1937 during a flight between Japan and England. The design originated in July 1935 with an Army specification for a fast reconnaissance aircraft. The first prototype flew in May 1936 and exceeded all specifications and was pleasant to fly. Its only weaknesses were its poor forward visibility, somewhat longer takeoff and landing runs than desired, and a tendency to lose speed rapidly in turns. The first production aircraft began to be delivered in May 1937.

Prior to the outbreak of war in the Pacific, "Babs" was used to great effect in China, where Japanese air supremacy meant that it could pretty much go where it wanted and provide the Japanese army with excellent intelligence on Chinese troop movements. Its performance attracted the attention of the Navy, which lacked high performance reconnaissance aircraft, and the Navy ordered fifty aircraft for its own use. The Navy often used the C5M as a guide aircraft for fighter formations flying long distance missions in the Netherlands East Indies during the Centrifugal Offensive. After the C5M was withdrawn from front-line service in the second year of the war, the survivors were used as trainers, and a few were eventually expended as kamikazes.
