This Article is a list of United States Air Force aircraft control and warning squadrons active, inactive, and historical. The purpose of an aircraft control and warning squadron is to provide an airborne radar picket to detect vessels, planes, and vehicles before they enter an area of operations, as well as providing command and control in an engagement by directing aircraft strikes.
The Distant Early Warning (DEW) Line, constructed in the late 1950s, was reaching obsolescence in the 1980s.With the signing of North American Air Defence Modernization agreement at the "Shamrock Summit" between Prime Minister Mulroney and President Reagan in Quebec City on 18 March 1985, the DEW Line began its eventual upgrading and transition becoming the North Warning System (NWS) of today.
The Ballistic Missile Early Warning System (BMEWS) was a radar system built by the United States (with the cooperation of Canada and Denmark on whose territory some of the radars were sited) during the Cold War to give early warning of a Soviet intercontinental ballistic missile (ICBM) nuclear strike, to allow time for US bombers to get off the ground and land-based US ICBMs to be launched, to ...
Coverage of the original PAVE PAWS and BMEWS systems, later upgraded to SSPARS and eventually to UEWR BMEWS solid-state phased-array radar at RAF Fylingdales. The Solid State Phased Array Radar System [1] (SSPARS), colloquially Ballistic Missile Early Warning System radar network (BMEWS radar network), [2] is a United States Space Force radar, computer, and communications system for missile ...
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external ("offboard") source—as it reflects off the target [1] [2] (in contrast to active radar homing, which ...
Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat.
