The Distant Early Warning Line
  • The Distant Early Warning Line (DEW line) is a system of radar stations in the northern Arctic region of Canada stretching from Alaska through Canada and over to Greenland and Iceland and was used to detect external threats/attacks that could threaten North American cities.
  • The DEW system was active from 1957-1993 and was built during the Cold War as a means of protection for the United States and Canada.
  • Due to evolving technology, the DEW Line was shut down and the North Warning System took its place.
