- The B2M was a British-designed aircraft built by
Blackburn, which submitted the design to the Japanese Navy and which was
subsequently accepted in 1929. Four prototypes were subsequently built. The
aircraft entered production in 1932 with the Mitsubishi designation of B2M1
and the Navy designation of Type 89, Model 1. Serviceability modifications
resulted in the B2M2. Production ceased in 1935 with a total of 204 B2M’s
(less prototypes) built.
