used by all three branches of the armed forces. On February 1, 1968, the merger of the three service branches into the unified Canadian Forces saw the end of flight operations at the Debert aerodrome and in 1971 the Department of National Defence designated , consisting of the aerodrome and the majority of the training area used by the former Camp Debert, as surplus. The provincial government purchased this land for development into the "Debert Air Industrial Park" while the aerodrome continues to be used as a municipal airfield, known as Debert Airport. Maritime "Diefenbunker” In 1958, at the height of the Cold War and the infancy of the ICBM threat, Debert was selected as the site for 1 of 6 communication centres and "Regional Emergency Government Headquarters" complexes being located across Canada. The Debert facility would be the only such complex built in the Maritime provinces. A small part of Camp Debert was proposed to be used for the complex along with supporting surface structures and personnel housing. Construction began in 1960 on an underground 2-storey bunker (approximately half the size of the CEGHQ, located in Carp, Ontario) capable of withstanding a near-hit from a nuclear explosion (an approximate radius). The underground building had blast doors at the surface, as well as extensive air filters (mainly against biological, chemical and radioactive contaminants). Underground storage was built for food, fuel, fresh water, and other supplies for the facility which was capable of supporting 350 people for 90 days. These blast shelters, nicknamed "Diefenbunkers", were administered by the Canadian Corps of Signals. Opening in 1964, the Debert facility was already outdated, since ICBM targeting had improved to the point where a direct hit was possible on the bunker. However the site persisted as a Provincial Warning Centre (for Nova Scotia), staffed by the 720 Communication Squadron, along with the space for the emergency government. Antenna farms were dispersed from the bunker and were located on the shores of Cobequid Bay in nearby Masstown as well as in the Cobequid Hills near Londonderry. On February 1, 1968, the merger of the three service branches into the Canadian Forces saw the Diefenbunker and support facilities, the last remnants of Camp Debert, change its name to Canadian Forces Station Debert (CFS Debert), in keeping with the naming convention for minor military facilities across Canada. In the 1970s, CFS Debert, as with most Diefenbunker facilities
