Kh-31A high-speed anti-ship intermediate-range ballistic missile

This missile is designed to destroy surface vessels (up to destroyer type targets, inclusive) navigating either individually or as a part of naval strength groups, capable of operating under any weather conditions and at any time of the day.

It’s in service since 1988-1990, now it’s operating as a part of modern airborne weapon systems such as Su-24M, Su-32, Su-35, Su-30MKI, Su-30KN, Su-30MK, MiG-29.

The missile features active radar homing head, radio altimeter and powered by combined power plant consisting of solid-fuel booster und ramjet sustainer running on kerosene. Payload type – penetration.

Kh-31A  features normal aerodynamic design with X-shaped location of wing panels and fins. It works in coordination with armament and navigation system, as well as weapon-control system as a part of carrier’s airborne hardware.

Used in two modes: in shared one with autofollowing target acquisition performed by radar homing head that is situated on the load under the carrier. In automated one with autofollowing target acquisition performed by radar homing head on the missile’s path (after launching) over a distance in 7-20 km to the target. Carrier crew decides which mode is better depending on flight altitude and target. After the cross shape generator of carrier’s radar has found its target and sent a command, it begins the calculation of authorized launching zone and informs about the launching preparation process. 

When the aircraft is in authorized launching zone, it’s given a signal of weapon employment.
