The Nakajima B5N (Japanese: 中島 B5N, Allied reporting name "Kate") was the standard torpedo bomber of the Imperial Japanese Navy (IJN) for much of World War II.
While the B5N was substantially faster and more capable than its Allied counterparts (the TBD Devastator, Fairey Swordfish and Fairey Albacore), it was close to obsolescence by 1941. Nevertheless, the B5N operated throughout the whole war, due to the delayed development of its successor, the B6N. In the early part of the Pacific War, flown by well-trained IJN aircrews and as part of well-coordinated attacks, the B5N achieved particular successes at the battles of Pearl Harbor, Coral Sea, Midway, and Santa Cruz Islands.
Although primarily used as a carrier-based aircraft, it was also used as a land-based bomber upon occasion. The B5N had a crew of three: pilot, navigator/bombardier/observer, and radio operator/gunner.

As Described In
Aces of the Pacific: The Nakajima B5N Type 97 Kate served as the IJN's primary torpedo bomber from the outset of the war until late 1943. Its lack of armament made it an easy target for American fighters.
1942 Pacific Air War: The Kate is quite a stable platform for torpedo bombing. The maneuverability is adequate, but certainly no match for a fighter in a one-on-one fight. The stall on the Kate is easily handled and not at all dramatic. This plane can take more punishment than a Reisen, but a successful run requires fighter cover.
