The system is mounted in an enclosed automatic turret and directed by MR-123 radar and television detection and tracking. The weapon's primary purpose is defense against aircraft and helicopters. As one of the tried-and-true CIWS systems available, effectiveness against anti-ship missiles has been demonstrated over the years in exercises,[12] making it the staple anti-air weapon of most Soviet naval vessels.
The AK-630 can also be employed against ships and other small craft, coastal targets, and floating mines. Once operational, the system was rapidly adopted and installed in every new Soviet warship (from mine-hunters to aircraft carriers) with up to eight units on larger vessels; hundreds have been produced in total.
