AK-230
Encyclopedia
AK-230 is a Soviet
fully automatic naval twin 30 mm gun
. Its primary function is anti-aircraft. It is mounted in an enclosed automatic turret and directed by radar
. AK-230 is probably the most popular gun of its class in the world, mounted on big warships as well as small crafts. About 1450 guns were produced in the USSR and about 300 were produced in China
as the Type 69. It was succeeded by the more powerful AK-630
from the mid to late 1970s.
Development of the weapon began during the 1950s with the first trail weapon fitted to the Osa class of fast attack missile boats and Shershen class torpedo boats. The weapon was officially accepted into service in 1969.
s, which are mounted inside a riveted steel turret. The gun mechanism is driven by the recoilling barrel (recoil-operated revolver gun). The guns each weigh 155 kg and have barrels 1930 mm long, and a total length of 2670 mm. 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 gasses are used to eject the spent shells and belt links into a space between the magazine and the hull. Ballistic maximum range for the weapon is about 6.7 km - but realistic ranges for engaging air targets are quoted as between 2.5 and 4 km.
The weapon is remote directed, typically by a fire-control system linked to either a Drum Tilt or Muff Cobb radar systems.

Description
The weapon consists of two stabilized NN-30 30 mm water-cooled four chamber revolver cannonRevolver cannon
A revolver cannon is a type of autocannon commonly used as an aircraft gun. It uses a cylinder with multiple chambers, like those of a revolver handgun, to speed up the loading-firing-ejection cycle. Some examples are also power-driven, to further speed the loading process, but this is by no means...

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 RomaniaRomania
