Cartwright Air Station
Cartwright Air Station (ADC ID: N-27) is a closed General Surveillance Radar station. It is located  east-northeast of CFB Goose Bay, Newfoundland and Labrador. It was closed in 1968. History
The site was established in 1953 as a General Surveillance Radar station, funded by the United States Air Force (USAF). It was used initially by the Northeast Air Command, which stationed the 922d Aircraft Control and Warning Squadron on the station on 1 October 1953. The station functioned as a Ground-Control Intercept (GCI) and warning station. As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes. It was equipped with the following radars:
 Search Radar: AN/FPS-3C, AN/FPS-502, AN/FPS-20A, AN/FPS-87A, AN/FPS-93A
 Height Radar: AN/TPS-502, AN/FPS-6B, AN/FPS-90

The station was reassigned to the USAF Air Defense Command on 1 April 1957, and was given designation "N-27". In 1963, the site was connected to the Manual Data Center at Goose AFB. In addition to the main facility, Cartwright operated several AN/FPS-14 manned Gap Filler sites:
 Cut Throat Island Air Station (N-27A): 
 Spotted Island Air Station (N-27B):  
 Fox Harbour Air Station (N-27C): 

On 18 June 1968, the USAF transferred control of the site to the Canadian Armed Forces. It was inactivated, closed and the remains of the station are abandoned. USAF units and assignments
