The Kortik is a major improvement over the AK-630, but is also a much large, more complicated and more expensive system.

3K95 Kinzhal

The Kinzhal is a naval SAM system with vertical launch system. This system was rumored to be favored over the Kortik since its engagement zone against aircraft is significantly large and performance against incoming anti-ship missiles reportedly better than the original 9M311K missiles.
