The AK-630 is a Soviet fully automatic naval close-in weapon system based on a six-barreled 30 mm Gatling gun. It is mounted in an enclosed automatic turret and directed by radar and television detection and tracking. The system's primary purpose is defense against anti-ship missiles and other precision guided weapons. However it can also be employed against fixed or rotary wing aircraft, ships and other small craft, coastal targets, and floating mines. The AK-630 was one of the first ever CIWS systems: when it was developed, there were no Phalanx, DARDO or Goalkeeper systems; however, the long development time of the AK-630 partially negated this advantage. Once operational, this weapon system was rapidly adopted, with up to 8 units installed in every new Soviet warship (from mine-hunters to aircraft carriers), and hundreds produced in total.
