ww2dbaseIn 1925 the Imperial Japanese Army rejected Mitsubishi's experimental 2MB2 Washi two-seat light bomber designed by Alexander Baumann, in favour of Herbert Smith's more conventional 2MB1 design. The 2MB1, which entered service in 1927 under the designation Army Type 87 Light Bomber, was a large two-seat biplane with a wide-track divided landing gear.
ww2dbaseForty-eight aircraft were built for the IJA, each powered by a 450-hp Hispano-Suiza engine which gave a maximum speed of 115 mph. Defensive Armament consisted of a single fixed forward-firing 7.7mm machine gun, plus twin guns of a similar calibre on a ring mounting in the rear fuselage for the observer. In addition provision was made for a fourth gun firing through a ventral trap-door.
ww2dbaseThe 2MB1 biplanes participated in ground support roles in northeastern China in the region known as Manchuria from late 1931 until early 1932, but by the mid-1930s, they were considered obsolete for further front-line service and relegated to a training duties for the remainder of their service life.
