History Brief
Allied code-named “Kate,” the B5N2 was a highly maneuverable aircraft for its type, powered by one Nakajima Sakae 21, a twin-row 14-cylinder 1000 hp radial engine. With a top speed of 235 mph, it had a operational range of 610 miles. A three-man crew was standard. Its armament featured one 7.7mm machine gun for rearward defense and payload capacities of either one 800kg bomb, two 250kg bombs, six 60kg bombs, six 30kg bombs, or one 800kg torpedo. Officially adopted in December 1939 as a follow-up of the B5N1, the B5N2 Type 97 proved to be an accurate bombing and torpedo platform and easily found its way to all six IJN carriers in the Nagumo task force that attacked the U.S. Pacific Fleet in the Pearl Harbor raid. The type 97 became the Navy’s mainstay in the early stages of the war wherever it saw extensive action, including combat campaigns in the Solomons, Southwest Pacific, and Indian Ocean.
