Permanent System radar stations
The Permanent System ("P system") was a 1950s radar network ("P radar net") used for the CONUS "manual air defense system" and which had a USAF aircraft control and warning (AC&W) organization of personnel and military installations with radars to allow Air Defense Command ground-controlled interception of Cold War bombers attacking the United States.
During World War II the United States Army organized a network of "Army Radar Stations", Aircraft Warning Corps information centers, Ground Observer Corps filter centers, and Fighter Control Centers (which were "inactivated...in April 1944") to provide air defence.
A similar post-war system was planned. The Distant Early Warning Line was "first conceived—and rejected—in 1946." General Stratemeyer forwarded an air defense plan to General Spaatz in November 1946. In the spring and summer of 1947, three Air Defense Command Aircraft Control and Warning (AC&W) plans went unfunded. e.g., the 8 April 1947, "air defense plan (long term)".
With only 5 "Air Warning Station" radars operating in 1948, the "Radar Fence Plan (code named Project SUPREMACY)" was planned for completion by 1953 with 411 radar stations and 18 control centers. The Radar Fence was rejected by ADC since "no provision was made in it for the Alaska to Greenland net with flanks guarded by aircraft and radar picket ships [required] for 3 to 6 hours of warning time" (the Alaska to Greenland net was eventually built as the Distant Early Warning Line).
ADC's Interim Program and its First Augmentation were planned "until the Supremacy plan network could be approved and constructed", and an $85,500,000 March 1949 Congressional bill funded both the Interim Program "for 61 basic radars and 10 control centers to be deployed in 26 months, with an additional ten radars and one control station for Alaska" and the augmentation's additional 15 radars ("essentially Phase II of Supremacy"). The resulting Lashup Radar Network was completed in April 1950 and was operational in June 1950.[citation needed]
On 13 February 1950, HQ USAF had "advanced the completion date from July 1, 1951, to December 31, 1950, for the most essential radar stations. The USAF reallocated $50 million for the "permanent Modified Plan" (modified from Supremacy) to "start construction on the high Priority Permanent System of radars in February 1950 with the first 24 radar sites to be constructed by the end of 1950". Early June 1950 exercises "in the 58th Air Division [tbd Lashup sites] indicated insufficient low-altitude coverage," and the Secretary of the Air Force requested a 2nd stage of 28 stations on 11 July 1950 (Secretary of Defense approval was on 21 July.)[citation needed]
By November 1950, Ground Observation Corps filter centers (7 in the west, 19 in the east) were being installed. By 10 November a separate Air Defense Command headquarters was approved, the Federal Civil Defense Administration was created in December 1950, and command centers communicated radar track information to the national ADC center that had moved from Mitchell Field to Ent Air Force Base on 8 January 1951.
The "original construction program for the Permanent System" was completed in May 1952, USAF AC&W squadrons were established (renamed Radar Squadrons in the mid-1950s), and the Ground Observation Corps was expanded in 1952 (Operation Skywatch) with over 750,000 volunteers at over 16 thousand posts (98 per post in shifts) and 75 centers.
