R-33E

The R-33E is a long range, air-to-air missile designed to be the weapon of choice for the Mig-31 air defense aircraft against highly valuable airborne threats such as strategic bombers and high altitude aircraft. It is capable of operation into heavy jamming environments and all weather conditions. Its ranges varies according to some reports from 120 km to 160 km depending on the launch altitude and airspeed. Once launched, the R-33 missile uses an inertial navigation and a semi-active radar system for midcourse guidance. In the terminal phase of the flight an active radar homing head is responsible for the missile guidance and target interception. The Mig-31 Foxhound is the sole aircraft enabled to use the R-33E missile.
