The Type 2 20 mm AA machine cannon was a Japanese-designed anti-aircraft gun. It entered service in 1942.
Introduced in 1942, compared to the earlier Type 98 20 mm AA machine cannon, Type 2 20 mm had higher maximum rate of fire, could be elevated to 95 degrees and had a central fire-control system.[1] The central fire-control system developed for the Type 2 could control and direct six of the guns at once. The gun was based on the German 2 cm Flak 30/38/Flakvierling.[2] It was driven by electric motors, obtaining its power from a generator trailer. 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.[3]
Two of the guns mounted together formed a variant known as the Type 2 20 mm twin AA machine cannon. The prototype Type 98 20 mm AAG tank was equipped with this twin Type 2 variant as its main armament. The Type 98 20 mm AAG tank did not enter production.
