Klamath Air Force Station (ADC ID: P-33, NORAD ID: Z-33) is a closed United States Air Force General Surveillance Radar station. It is 3.4 miles (5.5 km) northwest of Klamath, California, and was closed in 1981.

History

Klamath Air Force Station was one of twenty-eight stations built as part of the second segment of the

Secretary of Defense for approval to quicken construction of the permanent network. Receiving the Defense Secretary's approval on 21 July, the Air Force directed the Corps of Engineers to begin construction[1]
adjacent to the town of Requa, California, about 3 miles northwest of the town of Klamath and within sight of the mouth of the Klamath River.

The 777th Aircraft Control and Warning Squadron (AC&W Sq) was activated at the new station on 18 December 1950. The station initially was a "Lashup-Permanent" site (LP-33), operating an AN/TPS-1B radar. It joined the Permanent radar network,[2] 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.

From April 1952, the 777th AC&W Sq operated

AN/FPS-90, while the AN/GPS-3 was removed.[3]

During 1960, Klamath AFS joined the

Semi Automatic Ground Environment (SAGE) system, feeding data to DC-13 at Adair AFS, Oregon. After joining, the squadron was re-designated as the 777th Radar Squadron (SAGE) on 15 July 1960.[4]
The radar squadron provided information 24/7 to the SAGE Direction Center where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile.

By the end of 1961, the AN/FPS-20A long-range search radar had been upgraded and re-designated as an

AN/FPS-27 long-range search radar in operation there, and the AN/FPS-66 was subsequently retired.[3]

In addition to the main facility, Klamath personnel operated one

AN/FPS-14 Gap Filler site:[2]

Over the years, the equipment at the station was upgraded or modified to improve the efficiency and accuracy of the information gathered by the radars. In 1979, Klamath came under

ARSR-4.[2]

After military use ceased, the site's residential housing area was used by the

Redwood National Park. Following the opening of the park's North Operations Center near Crescent City, California
in 2009, the NPS began work to remove nearly all remaining buildings and infrastructure, to return the site to a more natural state. As of 2012, all former Air Force, FAA and NPS facilities had been removed, with only some cellular telecommunications equipment remaining at the site.
