Caribou Air Force Station
Caribou Air Force Station, also known as North River Depot and East Loring, is a defunct Air Force Station that operated from 1951 until some time when it was absorbed into Loring Air Force Base in 1962. It was located in Limestone, Maine, adjacent to Loring. Between 1951 and 1962 Caribou was an Operational Storage Site for Air Materiel Command (AMC-OSS), one of five in the United States, and the weapons storage and maintenance facility for Loring alert aircraft.
Cape Charles Air Force Station
L-15 was designated as Cape Charles Air Force Station, and it was one of twenty-eight stations built as part of the second segment of the permanent radar network. Prompted by the start of the Korean War, on July 11, 1950, the Secretary of the Air Force asked the Secretary of Defense for approval to expedite construction of the permanent network. Receiving the Defense Secretary’s approval on July 21, the air force directed the Corps of Engineers to proceed with construction. Because of difficulties with the new radar equipment, Cape Charles AFS initially received its radar equipment from the former Fort Curtis Lashup site to expedite operational status. Thus it was redesignated as LP-56. The 771st AC&W Squadron, continued operating the AN/CPS-4 and as of April 1952 an AN/FPS-3 radar as well. The AN/FPS-3 remained operational until 1962. Initially 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 intruders picked up on the unit's radar.
