 The mission of the ECRS radar system was redirected to counter-narcotics surveillance and drug interdiction, and the ECRS operated in this capacity for several years.The three OTH radars of the WCRS were mothballed, and the incomplete North Sector in Alaska was cancelled.The Air Force currently maintains the six East Coast and West Coast OTH-B radars in a state called "warm storage", which preserves the physical and electrical integrity of the system and permits recall, should a need arise.
