The AK-230 is a Soviet radar-controlled 30mm naval anti-aircraft autocannon. It is mounted in an enclosed automatic turret and directed by radar. The AK-230 is widely used, The guns each weigh and have barrels long, and a total length of . The barrels are rifled with 12 grooves. The guns each have a rate of fire of 1,000 round per minute; they are fed by independent 500-round belts of ammunition.

The rounds are electrically fired; propellent gases are used to eject the spent shells and belt links into a space between the magazine and the hull. The ballistic maximum range for the weapon is about , but realistic ranges for engaging air targets are quoted as between .

The weapon is remote-directed, typically by a fire-control system linked to either a MR-104 Rys (NATO reporting name: Drum Tilt) or MR-103 Bars (NATO reporting name: Muff Cobb) radar systems.

Ammunition

The AK-230 fires specially developed 30x210B 30 mm ammunition that is electrically primed. Two rounds were developed: a high-explosive round with an impact fuze, and an armour-piercing round. The Chinese Type 69 fires only a locally produced version of the high-explosive round. Ammunition is also produced in Romania and Serbia.
