The aircraft has one Shipunov 2A42 autocannon with selective fire, and a dual-feed, giving it a cyclic rate of fire between 200 and 800 rounds per minute.[1] It is mounted near centre of gravity for accuracy, and carries 460 high-fragmentation, explosive incendiary, or armour-piercing rounds. The type of ammunition is selected by the pilot during flight.[2] The integrated 30 mm cannon is semi-rigidly fixed on the helicopter's side, movable only slightly in elevation and azimuth.[citation needed] Semi-rigid mounting improves the cannon's accuracy, giving the 30 mm a longer practical range and better hit ratio at medium ranges than with a free-turning turret mount.
