November 26/19: Technical Support The US Air Force awarded Raytheon a deal worth $72 million for advanced medium range air to air missile (AMRAAM) technical support. The contractor will provide technical services and analysis supporting the AMRAAM weapon system. AMRAAM is a continuation of the AIM-7 Sparrow missile series. The missile is faster, smaller and lighter, and has improved capabilities against low altitude targets. It incorporates an active radar with an inertial reference unit and a microcomputer system, which makes the missile less dependent on the aircraft’s fire control system. Once the missile closes on a target, its active radar guides it to intercept. This allows the pilot to aim and fire several missiles simultaneously at multiple targets. The pilot can perform evasive maneuvers while the missiles are guided to their objectives. Raytheon will perform work in Tucson, Arizona. Estimated completion date is September 30, 2025.

Raytheon’s AIM-120 Advanced, Medium-Range Air to Air Missile (AMRAAM) has become the world market leader for medium range air-to-air missiles, and is also beginning to make inroads within land-based defense systems. It was designed with the lessons of Vietnam in mind, and of local air combat exercises like ACEVAL and Red Flag. This DID FOCUS article covers successive generations of AMRAAM missiles, international contracts and key events from 2006 onward, and even some of its emerging competitors.

One of the key lessons learned from Vietnam was that a fighter would be likely to encounter multiple enemies, and would need to launch and guide several missiles at once in order to ensure its survival. This had not been possible with the AIM-7 Sparrow, a “semi-active radar homing” missile that required a constant radar lock on one target. To make matters worse, enemy fighters were capable of launching missiles of their own. Pilots who weren’t free to maneuver after launch would often be forced to “break lock,” or be killed – sometimes even by a short-range missile fired during the last phases of their enemy’s approach. Since fighters that could carry radar-guided missiles like the AIM-7 tended to be larger and more expensive, and the Soviets were known to have far more fighters overall, this was not a good trade.
