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,^[1] mounted on large warships as well as small craft. 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.
