Introduced in the late 1980s, the GIAT 30 is a revolver cannon with electric ignition and automatic recocking.

Primarily intended for helicopter use and offered in several fixed, podded, and turreted installations.

It is 1.87 m (6 ft 2 in) long with a total system weight of 65 kg (143 lb).

Typical muzzle velocity is 810 m/s (2,700 ft/s) with a rate of fire of 750 rounds per minute.

Given its considerable recoil, it is typically used for single shots or controlled bursts rather than continuous fire.
