The Vympel R-33 (AA-9 Amos) is a long-range air-to-air missile developed by the Soviet Union. It is the primary armament of the MiG-31 interceptor, intended to attack large high-speed targets such as the SR-71 Blackbird, the B-1 Lancer bomber, and the B-52 Stratofortress.
Generally similar to the U.S. Navy's retired AIM-54 Phoenix, it uses a combination of semi-active radar homing for initial acquisition and mid-course updates, and inertial navigation to reach the target at extreme range. The Zaslon phased array radar of MiG-31 allows four missiles to be guided simultaneously at separate targets.
The R-33 AAM remains in service with the CIS and Russian forces (See MiG-31 operators). It may have been deployed during the chechen conflicts as MiG-31's provided Air defense in conjunction with A-50 AWACS planes.
