CFB Shearwater
Royal Canadian Air Force Base Shearwater , commonly referred to as RCAF Shearwater, was a Canadian Forces base located east southeast of Shearwater, Nova Scotia, on the eastern shore of Halifax Harbour in the Halifax Regional Municipality. Following a base rationalization program in the mid-1990s, the Canadian Forces closed CFB Shearwater as a separate formation and realigned the property's various facilities into CFB Halifax. These include: History. 1918-1939. Shearwater is the second-oldest military aerodrome in Canada. In August 1918 the US Navy established Naval Air Station Halifax on the shores of Eastern Passage to support flying  boat patrol aircraft. The seaplane station was taken over by the Air Board in 1920 for civil flying operations, and later developed by the Canadian Air Force and the Royal Canadian Air Force. World War II. The station was known as RCAF Station Dartmouth through the Second World War. Aerodrome. In approximately 1942 the aerodrome was listed as RCAF Aerodrome - Dartmouth, Nova Scotia at with a variation of 23 degrees west and elevation of . The field was listed as "all hard surfaced" and had four runways but only the first is readable as follows: By January 1943 the runway information  had been updated and the four runways were listed as follows: Post-war. In 1948, the Royal Canadian Navy took over the facility, naming it HMCS "Shearwater", also known as Royal Canadian Naval Air Station Shearwater (RCNAS Shearwater). The combined land and sea-based aerodromes were used to station carrier-based maritime patrol and fighter aircraft. Shearwater was also the home to early experiments with ship-borne helicopters—something which was copied by navies around the world. During the 1960s, the aerodrome at the former RCAF Station Debert was attached to HMCS "Shearwater" as a training location for carrier landings . The February 1, 1968 unification of the three service branches into the Canadian Forces saw HMCS "Shearwater" change its name to Canadian Forces Base Shearwater (CFB Shearwater). Base rationalization and defence budget cutbacks for the Canadian Forces during the mid-1990s saw a largely administrative move when the formation CFB Shearwater stood down and the facilities transferred to the formation CFB Halifax and aircraft operations becoming the responsibility of newly formed 12 Wing. 12 Wing is headquartered at Shearwater and reports to 1 Canadian Air Division. Heliport conversion project. During the late 1990s and early 2000s the Shearwater airfield was scaled  back significantly as the facility transitioned to a heliport with surplus lands identified and transferred to Canada Lands Company. Prior to 2002, Shearwater had two asphalt runways: By 2002 only runway 10/28 remained open. As part of the Department of National Defence's Shearwater Heliport Conversion Project, runway 10H/28H was reduced in length to the east end only in July 2007. At the same time, runway 16H/34H was reopened, but for helicopter operations only. These changes allowed for heliport operations including instrument approaches and were accompanied with the construction of other non-airfield facilities in support of the Maritime Helicopter  Project. Shearwater Heliport opened July 31, 2008, consisting of a new 16H/34H and various helipads for helicopter operations only. As part of the heliport conversion project, the old runway 16/34 was permanently closed and placed outside (east) of a new fence for the Shearwater Heliport, as shown in the Canada Flight Supplement effective 31 July 2008. This land for the old runway 16/34 was then transferred by the Department of National Defence to the Canada Lands Company for sale. On 3 April 2009 the land for the old runway 16/34 was re-transferred from Canada Lands Company back to DND , however its future use is unknown. Shearwater Heliport's primary mission remains as a heliport in support of the Royal Canadian Navy's Maritime Forces Atlantic warships with shipborne helicopters operated by 12 Wing, a unit of the Royal Canadian Air Force. 12 Wing's squadrons at Shearwater Heliport in Nova Scotia and at Patricia Bay in British Columbia operate the Sikorsky CH-148 Cyclone. There are numerous construction projects ongoing at Shearwater Heliport in support of the Maritime Helicopter Project, including the Maritime Helicopter Training Centre where No. 406 Squadron will be located, as well as a new No.423 (MH ) Squadron hangar facility, a new 12 Air Maintenance Squadron facility with six repair bays, and a new Operational Support Facility where the Helicopter Operational Test and Evaluation Facility (HOTEF) and various 12 Wing headquarter functions will be located. Current operations. Current operations at Shearwater are administratively and operationally part of CFB Halifax and revolve around two functionally separate facilities: 12 Wing. The Shearwater Heliport is the location of the headquarters of 12 Wing, whose sole purpose is to support and operate shipborne helicopters for the Royal Canadian Navy. 12 Wing is a RCAF unit and reports to 1 Canadian Air  Division. 12 Wing operates out of two locations with four squadrons: Air shows. Beginning in the 1970s, CFB Shearwater began hosting an Armed Forces Day every fall, typically on the weekend following Labour Day, and included an air show where the long and wide runways at Shearwater hosted some of the largest aircraft in the world, including the U.S. Air Force's C-5 Galaxy transport planes and B-52 Stratofortress bombers. By the 1980s this air show came to be named the "Shearwater International Air Show" and was a popular event for military aviation enthusiasts in Eastern Canada and the Northeastern  United States as the location of CFB Shearwater, coupled with the popularity of the Halifax area among military aircrew, resulted in heavy international participation from the RCAF, as well as the USAF, United States Navy, United States Marine Corps, Royal Air Force and numerous other NATO air forces in Europe. Defence cutbacks and unit and facility realignments from 1994 to 1996 saw CFB Shearwater stand down as a separate formation and the facility merged as an airfield attached to CFB Halifax. At this time, the military-organized "Shearwater International Air Show" was transferred to a civilian organization that saw the  event renamed to the "Nova Scotia International Air Show." Organizers of the "Nova Scotia International Air Show" continued to make use the Shearwater airfield for both ground displays and the air show component until 2002. Modifications to the airfield from 2002 onward as part of the Shearwater Heliport Conversion Project saw runways closed, eliminating the ability of fixed-wing aircraft to land at Shearwater, forcing the airshow to remove the static (ground) display component of the event, with the air show component continuing to be staged in the skies over Shearwater (using the nearby Halifax Stanfield International Airport as the  fixed-wing airfield). The inconvenience of not having a ground component for the "Nova Scotia International Air Show" as a result of the Shearwater Heliport Conversion Project saw the entire event moved to Halifax Stanfield International Airport beginning in 2004. From 2004 to 2008 the show was held at Halifax Stanfield International Airport which allowed for both static (ground) display and air show at the same venue, however the airport was deemed unsuitable due to numerous interruptions in the air show component by civilian air traffic movements. The air show moved to Yarmouth Airport in 2009 but returned to Shearwater  in 2010, the first time since 2003 that an air show was held at the historic airfield (but again with no ground component). In 2011 the air show was renamed the "Atlantic Canada International Airshow" and was held at the Summerside Airport, formerly CFB Summerside, to commemorate the 70th anniversary of the establishment of that base. Organizers have stated that the "Atlantic Canada International Air Show" will likely rotate through the Shearwater airfield every second year.
