History

Early air-to-air missiles used semi-active radar homing guidance, that is the missile used the radiation produced by the launching aircraft to guide it to the target. The latest generation of BVR missiles use a combination of semi-active and active radar. The first such missiles were relatively simple

became the first operational BVR missile in 1954. These primitive BVR missiles were soon replaced by missiles using semi-active radar homing (SARH). This is where the launching aircraft's radar is "locked" onto the target in a single target track (STT) mode, directing a radar energy at the target that the missile seeker can "see" as it reflects off the target. The radar antenna must "illuminate" the target until impact. Missiles like the Raytheon

homes in on the reflected laser radiation. Some of the longest-range missiles in use today still use this technology. An AIM-7 variant called Sparrow II was the first attempt at producing a semi-active radar homing missile, however the first air-to-air missile to introduce a terminal active seeker operationally was the AIM-54 Phoenix carried by the F-14 Tomcat, which entered service in 1972. This relieved the launch platform of the need to illuminate the target until impact, putting it at risk. The Phoenix and its associated Tomcat radar, the

. These types of missiles have the advantage of not requiring the launching aircraft to illuminate the target with radar energy for the entire flight of the missile, and in fact do not require a radar lock to launch at all, only target tracking information. This gives the target less warning that a missile has been launched and also allows the launching aircraft to turn away once the missile is in its terminal homing phase or engage other aircraft.

Criticism

The efficacy of BVR air-to-air missiles has been criticized. A 2005 paper by USAF officer Patrick Higby showed that BVR missiles fell short of expected performance, despite incurring great cost. Because such missiles required large radars, they made aircraft heavier and increased drag, increasing aircraft procurement and operating costs. Fighters with BVR tended to be less agile than previous ones. Fighter pilots have been reluctant to use BVR missiles at BVR range because of difficulty in distinguishing friends and foes. As a result, most BVR missiles are fired at visual range. Western airforces only scored 4 BVR kills out of 528 kills made during 1965–1982; most kills during that period were made with guns or WVR missiles (

). The increased success rate of BVR combat during 1991 Gulf war may have significantly depended on other factors, such as assistance of AWACS, NCTR system of F-15Cs, as well as enemy incompetence. None of the Iraqi pilots took any evasive measures, either because of poor training or their radar warning receivers malfunctioned. One major issue with BVR is still unreliable IFF technology (

). In 2015 United States Naval Air Forces commander Vice Adm. Mike Shoemaker cited the sensor fusion of the Fifth-generation jet fighter Lockheed Martin F-35 Lightning II as the way to "bring that long-range ID capability and then share that information" with other platforms.
