Today the early warning role has been supplanted to a large degree by airborne early warning platforms. [1] By placing the radar on an aircraft, the line-of-sight to the horizon is greatly extended. This allows the radar to use high-frequency signals, offering high resolution, while still offering long range.

A Royal Air Force Boeing E-3 Sentry over North Yorkshire. An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack ...
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.
An early warning system is a warning system that can be implemented as a chain of information communication systems and comprises sensors, event detection and decision subsystems for early identification of hazards. They work together to forecast and signal disturbances that adversely affect the stability of the physical world, providing time ...

It primarily used the Chain Home radars for early warning, supplanted by Chain Home Low and a handful of other special-purpose early warning designs. For fighter direction, or ground controlled interception (GCI) as it was known, the primary system was the somewhat more modern AMES Type 7 , with smaller numbers of the advanced AMES Type 14 ...
