Nakajima B5N

The Nakajima B5N (Allied reporting name: Kate) was the Imperial Japanese Navy standard torpedo bomber for the first years of World War II. While the B5N was substantially faster and more capable than its Allied counterparts, it was close to obsolescence by the time of the Pearl Harbor attack. Nevertheless, the B5N operated throughout the whole war. Although primarily used as a carrier-based aircraft, it was also used as a land-based bomber on occasions.
