The Type 2 20 mm AA machine cannon was a Japanese-designed anti-aircraft gun.

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.

[3] The central fire-control system developed for the Type 2 could control and direct six of the guns at once.

[1] It was driven by electric motors, obtaining its power from a generator trailer.

[5] Two of the guns mounted together formed a variant known as the Type 2 20 mm twin AA machine cannon.
