The "ADC/FAA joint-use facility" began operations in 1961 with an FAA ARSR-1C radar. [1] After the April 1, 1961, move of the 670th Radar Squadron (SAGE)--formerly the 670th AC&W Squadron—from San Clemente Island Air Force Station, the Los Angeles Air Defense Sector was activated June 1. [6]
The former J-31 San Pedro JSS ARSR-1 radar site, California USAF Battle Control System operators monitor the skies from the floor of the program's Eastern Air Defense Sector location. The Joint Surveillance System (JSS) is a joint United States Air Force and Federal Aviation Administration system for the atmospheric air defense of North America.
ARSR-2 was developed in the 1960s, also with a 200-mile range. From a user perspective, the ARSR-1 and ARSR-2 function nearly identically. Components that had proved troublesome in the ARSR-1 were redesigned in order to improve reliability. Existing ARSR-1 systems were retrofitted with the more reliable ARSR-2 components.
The FAA replaced the AN/FPS-7E with an ARSR-3 search radar, leaving the Air Force only responsible for the height-finder tower (by then an AN/FPS-116), which was removed c. 1988. In the late 1990s, the ARSR-3 was replaced by the ARSR-4. Today Mount Laguna is an FAA site, tied into the Joint Surveillance System (JSS). The former Air Force ...
Post-World War II radar stations included those of the 1948 "five-station radar net" and the Lashup network completed in 1950, followed by the "Priority Permanent System" with the initial (priority) radar stations completed in 1952 [3]: 223 as a "manual air defense system" [4] with Manual ADCCs (e.g., using Plexiglas plotting boards as at the 1954 Ent Air Force Base command center for ADC.) [3 ...
A Ground Equipment Facility of the Federal Aviation Administration (FAA) is a radar station or other designated Air Traffic Control site of the United States. Several of the facilities originated as Cold War SAGE radar stations, including some facilities of the joint-use site system (JUSS) [1] (e.g., San Pedro Hill Air Force Station provided radar tracks for both the Army and USAF).
The aircraft was at an altitude of 498 feet (152 metres) flying at 161 knots (298 km/h or 185 mph) about 1.1 nautical miles (2 km or 1.3 miles) from the runway at the moment the flight recorders ...
On 31 December 1962, Air Force moved the 635th RADS to Dauphin Island AFS, Alabama, however a detachment operated at Fort Lawton until March 1963. The Army continued operations at the site until the AADCP was inactivated 1 September 1974. The Fort Lawton radar site remains in use by the FAA today, still operating the ARSR-1E search radar.
