6-barreled OTO 30mm Rotary

The KKD-630 is a ship based close in weapons system employed by the Imperial Navy of Huvakia, based on a six-barreled 30 mm rotary cannon. In "KKD-630", "KKD" standing for close capital defense in Huvakian, "6" denoting 6 barrels and "30" meaning 30mm. It is mounted in an enclosed automatic turret and directed by MR-123 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. Once operational, this weapon system was rapidly adopted, with units installed in every new Imperial warship (from mine-hunters to aircraft carriers), and hundreds produced in total.

The gun mount is fully automated, and can also be remotely controlled by an operator from either the control console or via a remotely mounted gunsight. It has a higher firing rate than both the Goalkeeper and Phalanx (Block 1 and older) CIWS models. They are often mounted in pairs, with as many as four pairs mounted on the larger ships, providing an effective point defence (last) layer. However, like all gun-based CIWS, they suffer from short engagement times and the need for multiple volleys to effectively eradicate a threat.

A modernized version of the KKD-630 with two 30mm rotary cannons was showcased by A.I.E under the new name "Duet". Visually "Duet" differs from it's predecessor in having a new mount with a stealthy low RCS design compared with the more traditional rounded KKD-630 mounts. The updated weapons systems has roughly the same size and weight however allowing installation in existing ship mounts with little alterations.
