Spotted Island Air Station (ADC ID: N-27B) is a closed General Surveillance-Gap Filler radar station. It is located 195 miles (314 km) east of CFB Goose Bay, Newfoundland and Labrador.[1] It was closed in 1961.


The site was established in 1957 as a manned Gap Filler radar station, built by the United States Air Force, under operational control of Cartwright Air Station and part of the Pinetree Line of Ground-Control Intercept (GCI) radar sites.

The station was assigned to Aerospace Defense Command in 1957, and was given designation "N-27B". Aerospace Defense Command stationed the 922d Aircraft Control and Warning Squadron at the station in 1957. It operated an AN/FPS-14 manned Gap Filler search radar.[2]
