The Mitsubishi 2MB1 (service designation 八七式軽爆撃機, Army Type 87 Light Bomber) was a light bomber produced in Japan in the mid-1920s to equip the Imperial Japanese Army. It was developed in parallel to the 2MB2, but while that aircraft featured an innovative and unorthodox design, the 2MB1 was a more conservative approach 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.
