DEW Line - DISTANT EARLY WARNING LINE. A system and network of radar stations in the far northern Arctic region of Canada, with additional stations along the North Coast and Aleutian Islands of Alaska, in addition to the Faroe Islands, Greenland, and Iceland. It wa designed to detect Soviet long range bombers during the years of the Cold War. It largely became redundant with the development of ICBMs as the preferred delivery method of nuclear warheads.
The DEW Line was the northernmost and most capable of three radar lines in Canada; the joint Canadian-US Pinetree Line ran from Newfoundland to Vancouver Island, and the Mid-Canada Line ran somewhat north of this. The line started to lose much of its purpose. It was useless against ICBMs and submarine-launched attacks. A number of stations were decommissioned, but the bulk were retained to monitor potential Soviet air activities and to assert Canada's sovereignty in theArctic.
