AK-630The design of the AK-630 CIWS was initiated in 1963, with the first operational prototype completed in 1964. Trials of the complete system, including radar and controls went on until 1976 when the system was accepted for service.
AK-630MDuring the deployment of the system, numerous problems that did not appear in trials were exposed in its application, and some modification of the original AK-630 was made to correct these problems, and in 1979, the new system was named as AK-630M and was accepted into service.
AK-306A derivatives of AK-630M was developed for light craft and this system was named as AK-306. Externally, the air-cooled AK-306 can be distinguished from the AK-630 by the absence of the water cooling system (a cylindrical jacket that surrounds the barrel cluster of the AK-630). Internally, the AK-306 (A-219) used electricity to power the automatics, instead of using the exhaust. This version also lacked radar control, being only optically guided, hence making it less of an anti-missile weapon and more of a surface-to-surface weapon, and the designation of the overall system is consequently changed from A-213-Vympel-A to A-219. The design started in 1974 and the system was accepted into service in 1980. When production completed in 1986, 125 systems entered service.
