Variants

2MB1 was based closely on the 2MT carrier-based torpedo bomber that was already in production for the Imperial Japanese Navy.

Like the 2MT, the 2MB1 was a conventional two-bay biplane with open cockpits in tandem and fixed tailskid undercarriage.

The 2MT’s Napier engine and side-mounted radiators were exchanged for a Hispano-Suiza engine and frontal radiator, and specific naval features such as folding wings were deleted.

The type saw action in the early stages of Japan’s Invasion of Manchuria in 1931, but it was found to be obsolete and was soon relegated to training duties.

48 Built.
