Nakajima B5N

The Nakajima B5N1 was the standard torpedo bomber of the Imperial Japanese Navy for much of World War II. The Allied code name for the plane was Kate. While the B5N1 was substantially faster and more capable than its Allied counterparts, the TBD Devastator and Fairey Swordfish, 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.

The Nakajima B5N1 were used by the invading Japanese against the US forces at Hawaii, and later against the US fleet during their first attempt to retake Hawaii. The planes still proved to be useful, however, by 1943, the torpedo planes were hopelessly outmatched and nearly all of them were destroyed as they attacked their targets or attempted to return to their carriers.
