The Ho-5 (Army Type 2) was a Japanese aircraft autocannon used in World War II. Developed from the Ho-103 machine gun, it was a version of the American Model 1921 Browning aircraft machine gun. It replaced the Ho-1 and Ho-3 (Army Type 97) in general service. The Ho-5 used using typical Browning style steel disintegrating link belts. The round used was a shortened version of the Allied 20 x 110mm Hispano-Suiza HS.404.
The Ho-5 was used mostly as wing mounts in late-war fighter planes, but saw limited use as cowl mounted in fighters and as flexible mounted in bombers.
