Oakdale Air Force Station (ADC ID: RP-62, NORAD ID: Z-62) is a United States Air Force General Surveillance Radar station. It is located 1.3 miles (2.1 km) east of the Pittsburgh suburb of Oakdale, Pennsylvania. It was closed in 1969.

## History

Oakdale Air Force Station was established in 1959 at the Oakdale Army Installation near Pittsburgh and activated in August 1960 with the transfer of the 662d Radar Squadron from Brookfield Air Force Station, Ohio, which was closed. Oakdale was designated RP-62, reflecting the replacement (R) of P-62 site at Brookfield. The move of the 662d Radar Squadron was part of a consolidation of Army and Air Force Radar units for budget considerations.
The United States Army had established Army Air-Defense Command Post (AADCP) P-70DC for the Nike Missile air-defense system, Pittsburgh Defense Area. The site had an FAA ARSR-lA search radar providing air-traffic-control data, as well as a pair of AN/FPS-6B height-finder radars, and 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 unidentified intruders picked up on the unit's radar scopes.
During 1960 Oakdale AFS joined the Semi Automatic Ground Environment (SAGE) system, initially feeding data to DC-03 at Syracuse AFS, New York. After joining, the squadron was re-designated as the 662d Radar Squadron (SAGE) on 15 July 1960. The radar squadron provided information 24/7 the SAGE Direction Center where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile.
An AN/FPS-20 search radar was installed in 1962. On 31 July 1963, the site was redesignated as NORAD ID Z-62. In 1963 this radar operated with AN/FPS-24 search radar as well as AN/FPS-26A and AN/FPS-90 height-finder radars (the Army also operated a pair of height-finder radars for a while, in support of Nike missile defense operations). The AN/FPS-20 was retired in 1966.
In addition to the main facility, Oakdale operated two unmanned AN/FPS-14 (RP-62B/G) and AN/FPS-18 (P-62A/E) Gap Filler sites

The Thompson and Lewisville sites, along with the former Brookfield AFS were transferred to Oakdale when Brookfield AFS was deactivated in 1960. The Thomas site was reassigned to Oakdale with the closure of Manassas AFS, VA in 1958. All Gap filler sites ere closed in June 1968.
Air Force operations ended with 662nd Radar Squadron (SAGE) inactivating on 31 December 1969. Army operations ended in 1974. The FAA retained the radar site, and replaced the AN/FPS-24 with an AN/FPS-67B search radar, still in use today on the old FPS-24 tower.
