[5], From a standing start in December 1954, many thousands of skilled workers were recruited, transported to the polar regions, housed, fed, and supplied with tools, machines, and materials to construct physical facilities – buildings, roads, tanks, towers, antennas, airfields, and hangars – in some of the most hostile and isolated environments in North America. The Navy was assigned the duty of providing the overwater radar-equipped aircraft for each end of the DEW Line. However, the American flags were lowered at the Canadian stations and only the Canadian flag remained. The Pacific Barrier (PACBAR III) C-band radar is being installed at the Western Space and Missile Center to furnish Revolution 0 detection of foreign launches. [20] The DEW Line has also been linked to depleted fish stocks and carelessness in agitating local animals such as the caribou, as well as non-seasonal hunting. [5], The initial contract with the U.S. Air Force and the Royal Canadian Air Force provided for the design and construction of a small experimental system to determine at the beginning whether the idea was practicable.

Robert F. and William W. Ward. Not visible is the AN/FPS-23 "gap filler" doppler antenna. "Distant Early Warning Line Radars: The Quest For Automatic Signal Detection." Internal structure of barriers consisting of sand, broken shell fragments and boulder-gravel in Georgia, Florida, Texas, Oregon and Washington States are illustrated using GPR. Costs for the Canadian sector were still subsidized by the US. The DEW Line was built during the Cold War to give early warning of a Soviet nuclear strike, to allow time for US bombers to get off the ground and land-based ICBMs to be launched, to reduce the chances that a preemptive strike could destroy US strategic nuclear forces. They repurposed the site with some repurposed equipment, cutting out a patch of dense foliage and replanting it with a 40-foot radar tower.

Severe signal loss is noted on all barriers at approximately the level of the low tide. The DEW Line grew out of a detailed study made by a group of the nation's foremost scientists in 1952, the Summer Study Group at the Massachusetts Institute of Technology. Gulf Coast barriers have thin freshwater lenses (<4 m), below which brackish water attenuates electromagnetic energy. were combined into AIRBORNE EARLY WARNING BARRIER [12] If an unknown flight was detected, the DEW Line station would contact AMIS to see if a flight plan might have been missed; if not, NORAD was notified. Advanced site preparation began in December 1954, and the construction was carried out in a massive logistical operation that took place mostly during the summer months when the sites could be reached by ships. [19] In assessing the cleanup, new research suggests that off-road vehicles damaged vegetation and organic matter, resulting in the melting of the permafrost, a key component to the hydrological systems of the areas. Reminiscences of an Airborne Combat Information Center Officer 1960-1962, Midway Deployment. It had a payload capacity of 150 tons, and could traverse nearly any terrain.
