The first air-to-air IR missiles appeared in the 1950s. The technology allowed more compact missile designs and made it possible to develop IR man-portable air-defense systems (MANPADS) i.e. shoulder-launched missiles, which became operational by the 1960s. IR MANPADS are relatively cheap, quite robust, easy to operate and difficult to detect.
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.
Thule Site J (J-Site) is a United States Space Force (USSF) radar station in Greenland near Pituffik Space Base for missile warning and spacecraft tracking.The northernmost station of the Solid State Phased Array Radar System, the military installation was built as the 1st site of the RCA 474L Ballistic Missile Early Warning System and had 5 of 12 BMEWS radars.
The 12th Space Warning Squadron is a unit of the Space Delta 4 which is under Air Force Space Command. To accomplish its mission, the squadron operates the solid-state phased-array radar located at the Ballistic Missile Early Warning System (BMEWS), Site I.
The site was known as the Concrete Missile Early Warning System (CMEWS) after the nearby town of Concrete, but when that town's post office closed in 1983 it became Cavalier Air Force Station, renamed Cavalier Space Force Station in 2021.
During deployment of the computerized air defense network for the United States, the Soviet Union announced that they had successfully tested an ICBM. BMEWS General Operational Requirement 156 was issued on November 7, 1957 (BMEWS was "designed to go with the active portion of the WIZARD system") and on February 4, 1958; the USAF informed Air Defense Command (ADC) that BMEWS was an "all-out ...
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 ...
The AN/AAR-47 Missile Warning System is a Missile Approach Warning system used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft's countermeasures systems. Its main users are the U.S. Army, U.S. Marine Corps, Navy and Air Force, but
