The Ho-5 (Army Type 2) was a Japanese aircraft autocannon used during 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 was belt-fed using typical Browning-style steel disintegrating links. The cartridge 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 fighters but saw limited cowl-mounted use in fighters and as flexible-mounted defensive armament (retrofit) in bombers.
