History

First flying in January 1937, the B5N replaced biplane torpedo bombers and was considered the world's finest carrier torpedo bomber at its introduction. B5N2s flying from six carriers sank USS Arizona, Oklahoma, West Virginia, and California at Pearl Harbor on 7 December 1941. The type also participated in attacks on HMS Prince of Wales and Repulse, and in the battles of Coral Sea and Midway.

Variants

The B5N1 was the initial production version; the B5N2 with the more powerful Sakae 11 engine became the main combat variant and was distinguished by a slightly larger cowling.

Where you'll see it

By mid-war the B5N was outclassed by Allied fighters and gradually relegated to anti-submarine patrols; retired from front-line service by 1944. No complete airworthy examples survive; a few museum restorations exist.
