resulting in mutual kills. What was needed was Phoenix-type multiple-launch and terminal active capability in a Sparrow-size airframe. This led to a memorandum of agreement (MOA) with European allies (principally the UK and Germany for development) for the US to develop an advanced, medium-range, air-to-air missile with the USAF as lead service. The MOA also assigned responsibility for development of an advanced, short-range, air-to-air missile to the European team; this would become the British ASRAAM. Requirements By the 1990s, the reliability of the Sparrow had improved so much from the dismal days of Vietnam that it accounted for the largest number of aerial targets destroyed in the Desert Storm part of the Gulf War. But while the USAF had passed on the Phoenix and its own similar AIM-47 Falcon/Lockheed YF-12 to optimize dogfight performance, it still needed a multiple-launch fire-and-forget capability for the F-15 and F-16. The AMRAAM would need to be fitted on fighters as small as the F-16, and fit in the same spaces that were designed to fit the Sparrow on the F-4 Phantom. The European partners needed AMRAAM to be integrated on aircraft as small as the BAe Sea Harrier. The US Navy needed the AMRAAM to be carried on the F/A-18 Hornet and wanted capability for two to be carried on a launcher that normally carried one Sparrow to allow for more air-to-ground weapons. Finally, the AMRAAM became one of the primary air-to-air weapons of the new Lockheed Martin F-22 Raptor fighter, which needed to place all of its weapons into internal weapons bays in order to help achieve an extremely low radar cross-section. Development AMRAAM was developed as the result of an agreement (the Family of Weapons MOA, no longer in effect by 1990), among the United States and several other NATO nations to develop air-to-air missiles and to share production technology. Under this agreement, the U.S. was to develop the next generation medium range missile (AMRAAM) and Europe would develop the next generation short range missile (ASRAAM). Although Europe initially adopted the AMRAAM, an effort to develop the MDBA Meteor, a competitor to AMRAAM, was begun in UK. Eventually, the ASRAAM was developed solely by the British, but using another source for its infrared seeker. After protracted development, the deployment of AMRAAM (AIM-120A) began in September 1991 in US Air Force McDonnell Douglas F-15 Eagle fighter squadrons. The US Navy soon followed (in
