 Since manned bomber raids by the Soviet Union in the area were considered quite likely, it was felt that RCAF Station Beaver Bank fulfilled a critical role in the early days of Canada's and North America's air defence.The station was originally financed by the United States Air Force, although operational responsibility rested with the RCAF, until 1962 when the RCAF assumed financial responsibility as well.In the mid-1970s the base was converted for a short time to a cement plant.
