Missile approach warning system

A missile approach warning system (MAWS) is part of the avionics package on some military aircraft. A sensor detects attacking missiles. Its automatic warning cues the pilot to make a defensive maneuver and deploy the available countermeasures to disrupt missile tracking.

Guided surface-to-air missile (SAM) systems were developed during World War II and began to make their presence felt in the 1950s. In response, electronic countermeasures (ECM) and flying tactics were developed to overcome them. ECM proved to be quite successful provided that a reliable and timely threat warning was given.

The first air-to-air IR missiles appeared in the 1950s. Subsequent miniaturization enabled IR man-portable air-defense systems (MANPADS)—i.e., shoulder-launched missiles, to become operational in the 1960s.

Since the 1960s, 70% of aircraft lost to enemy action were downed by passive heat-seeking—i.e., infrared (IR)—guided missiles[citation needed]—not radar-guided SAMs that generally have longer engagement ranges, are faster, can maneuver more sharply, carry larger warheads, and have proximity fuzes. The early-1970s development of radar warning receivers helped pilots evade radar-guided missiles, while defenses against passive-IR-guided missiles appeared later.

IR MANPADS are relatively cheap, quite robust, easy to operate and difficult to detect. They also do not require the infrastructure, such as radar dishes, associated with radar-guided SAM deployments that often reveals their presence.

Vast quantities of MANPADS have been manufactured (as many as 700,000 produced since 1970). They proliferated during the Cold War and immediate post Cold War era. Substantial quantities are available and affordable on the black market and have found their way into the hands of "non state" organizations or the so-called "asymmetric" threat. (An estimate by Jane's Intelligence Review of February 2003 puts this number as high as 150,000). An article "Proliferation of MANPADS and the Threat to Civil Aviation" of August 13, 2003 by Jane's Terrorism and Insurgency Centre estimates that the black market price of MANPADS like the SA-7 could be as low as $5,000.

Intelligence regarding the whereabouts of MANPADS, especially in the hands of "non state" organizations, is usually vague and unreliable. This, in turn, makes it difficult to anticipate where and when to expect MANPADS attacks.

The 2nd- and 3rd-generation MANPADS that appeared by the 1980s further increased the performance and effectiveness of MANPADS due to advanced new seeker head technology, improved rocket motors, and aerodynamic refinements. Their performance improved in terms of lethal range, minimum launch angle, maneuvering potential and all aspect engagement angles (1st-generation MANPADS were restricted to only rear sector attacks). They also became more electronic counter-countermeasure (ECM) resistant.
