OVERVIEW: The AIM-7M Sparrow III is a medium-to-long range, semi-active radar-guided air-to-air missile with digital guidance and improved all-weather, look-down/shoot-down performance, representing the most capable operational Sparrow variant before the AIM-120 AMRAAM.

DETAILS: Introduced in the early 1980s, the AIM-7M featured a new inverse monopulse seeker, a digital programmable signal processor for improved target tracking in cluttered environments, and significantly enhanced electronic counter-countermeasures (ECCM). It retained the AIM-7F’s dual-stage motor and modular design but offered vastly improved reliability, accuracy, and lethality. The missile was widely integrated with aircraft like the F-14, F-15, F-16, and F/A-18. It saw extensive use in the Gulf War, where it achieved a much-improved kill ratio compared to earlier variants.
