Type 98 20 mm AA machine cannon

The Type 98 20 mm AA machine cannon was the most common light anti-aircraft gun of the Japanese military. It entered service that same year and first saw combat in Nomonhan. It was used until the end of World War II. This weapon and its variants were based on the French design of the 13.2 mm Hotchkiss machine gun of the 1930s, which the Japanese forces had bought and further developed at home. The Type 98 was also one of the two armament options for the IJA's Submersible gun mount Model 1. ==Ammunition==

• Type 100 armour piercing tracer. Weight 162 g projectile and 431 g complete round. • Type 100 high-explosive tracer (with self-destruct). Weight 136 g projectile and 405 g complete round with 890 m/s. ==Variant==

Two of the guns mounted together formed a variant known as the Type 4 20 mm twin AA machine cannon. Approximately 500 to 548 of these guns were produced. ==See also==
