The AIM-120 Advanced Medium-Range Air-to-Air Missile, or AMRAAM (pronounced "am-ram"), is a modern beyond-visual-range air-to-air missile (BVRAAM) capable of all-weather day-and-night operations. Designed with 7-inch diameter instead of 8-inch diameter form-and-fit factors, and employing active transmit-receive radar guidance instead of semi-active receive-only radar guidance, it is a fire-and-forget upgrade to the previous generation Sparrow missiles. When an AMRAAM missile is being launched, NATO pilots use the brevity code Fox Three.
The AIM-7 Sparrow medium range missile (MRM) was purchased by the US Navy from original developer Howard Hughes in the 1950s as its first operational air-to-air missile with "beyond visual range" (BVR) capability. With an effective range of about 12 miles (19Â km), it was introduced as a radar beam-riding missile and then it was improved to a semiactive radar guided missile which would home in on reflections from a target illuminated by the radar of the launching aircraft. It was effective at visual to beyond visual range. The early beam riding versions of the Sparrow missiles were integrated onto the F3H Demon and F7U Cutlass, but the definitive AIM-7 Sparrow was the primary weapon for the all-weather F-4 Phantom II fighter/interceptor, which lacked an internal gun in its U.S. Navy, U.S. Marine Corps, and early U.S. Air Force versions. The F-4 carried up to four AIM-7s in built-in recesses under its belly.
