Type 2 20 mm AA machine cannon

The Type 2 20 mm AA machine cannon was a Japanese-designed anti-aircraft gun, based on the German Flak 38. It entered service in 1942. A central fire-control system was developed for the Type 2, which could control and direct six of the guns at once. The Type 2 number was designated for the year the gun was accepted, 2602 in the Japanese imperial year calendar, or 1942 in the Gregorian calendar.

Two of the guns were mounted on together to form the 20 mm Twin AA machine cannon.
