Variants

The K11W2 was an all-wood version built in small numbers.

The Q3W1 Nankai ("South Seas") was a two-seat antisubmarine version that failed to reach production after the prototype made a belly landing.


The K11W Shiraguki was a trainer for bomber crewmen with a rather unusual configuration. The pilot and radio operator/gunner sat in a greenhouse canopy above the wing while the instructor, navigator, and bombardier were in a cabin located under the wing.

The design originated in 1940 at Watanabe Tekkosho K.K. as a replacement for the K3M. The design resembled the American O-47. The prototype made its first flight in November 1942 and proceeded rapidly into production as no significant bugs were encountered. However, by the time production started, Watanabe Tekkosho had been absorbed into Kyushu Hikoki K.K.
