The Fort Meade radar station was a Cold War military site with several sets of radar equipment in various Army and USAF radar networks. The site operated c. 1950 until 1979 and had a Project Nike command post and radar network.

Lashup site L-14[edit]

Site L-14 of the temporary Lashup Radar Network was the ground-controlled interception radar station established at Fort George G. Meade until the radar's surveillance area was covered by a Quantico AFS radar in 1955. The Fort Meade radar station also had the first experimental AN/GSG-2 Antiaircraft Defense System in 1955.[1]

ARAACOM site W-13DC[edit]

In 1957 the Fort Meade station was designated an Army Air-Defense Command Post (AADCP) for the Washington-Baltimore Defense Area.[2] The site had the first operational Martin AN/FSG-I Antiaircraft Defense System, a fire distribution center for Nike Missiles and which was operated by the 35th Antiaircraft Artillery Brigade.[3] Designated W-13DC, the site had an AN/FPS-67 search radar and later a solid-state Hughes AN/TSQ-51 Air Defense Command and Coordination System.[4] After 1957, Fort Meade became the Headquarters, 2nd Region, Army Air Defense Command.

ADC site RP-54[edit]

On October 1, 1961, W-13DC was integrated[clarification needed] with the Aerospace Defense Command network as replacement site RP-54 operated by the USAF's 770th Airborne Control and Warning Squadron that transferred from former site P-54 at Palermo Air Force Station, New Jersey. Site RP-54 became part of the 1957 Washington Air Defense Sector) with an interface with the DC-04 SAGE system direction center at Fort Lee Air Force Station (inactivated March 1, 1983).

NORAD site Z-227[edit]

On July 1, 1963, the station was redesignated as site Z-227 (Palermo AFS re-opened as site Z-54), and the USAF unit was renamed the 770th Radar Squadron assuming control of the AN/FPS-67 and installing one each AN/FPS-6 and AN/FPS-6B height-finder radars by 1962. In 1964 an AN/FPS-90 replaced Meade's AN/FPS-6B, and the AN/FPS-6 was shut down; while in 1966 the AN/FPS-67 was upgraded to an AN/FPS-67B.[5][verification needed]

In addition to an annex at the former Manassas Air Force Station,[6] the Fort Meade radar station had unmanned AN/FPS-14 Gap Filler annexes at Hermanville, Maryland (RP-54A/Z-227A, 38°13′40″N 076°24′33″W / 38.22778°N 76.40917°W / 38.22778; -76.40917 (RP-54A)) and Hanover, Pennsylvania (RP-54B/Z-227B, 39°51′28″N 076°56′52″W / 39.85778°N 76.94778°W / 39.85778; -76.94778 (RP-54B)).[citation needed] The Washington AADCPs at Suitland & Ft Meade were deactivated on September 1, 1974; and USAF air defense operations at Ft Meade ended October 1, 1979 (a plan to use the site in the 1983 Joint Surveillance System was not implemented).[citation needed]
