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.

Design[edit]

Introduced in 1942, the gun was similar to the Type 98 20 mm AA machine cannon, but these 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.[1] 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.[2]

Variant[edit]

Type 2 20 mm Twin AA machine cannon

Two of the guns mounted together formed a variant known as the 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 did not enter production.[3]
