Editing North Warning System (section)

==History==
The [[Distant Early Warning Line|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 [[Brian Mulroney|Mulroney]] and President [[Ronald Reagan|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.

The NWS began limited operation in 1988 with the commissioning and acceptance of the three newly constructed east coast sites BAF-3 [[Brevoort Island]], [[Nunavut]], LAB-2 [[CFS Saglek|Saglek]] and LAB-6 [[Cartwright Long Range Radar Site|Cartwright]], both in [[Labrador]]. Throughout the late 1980s and early 1990s, new NWS LRR radars replaced former DEW Line sites. DEW sites that were not transitioned to North Warning operation were eventually closed down. The official activation of the NWS and inactivation of the DEW Line took place on 15 July 1993.

The bi-national North Warning System Office (NWSO) is located in Ottawa, Ontario and staffed with both Canadian and American military and civilian personnel. Staffed sites are operated by the [[Royal Canadian Air Force]], but physically staffed by civilian contractors. Logistical and maintenance support for the NWS is supplied by the [[Air Force Materiel Command]] of the United States Air Force, located at [[Ogden Air Logistics Center]] (OO-ALC), [[Hill Air Force Base]], Utah.
