United States general surveillance radar stations

For military and civilian sites of the U.S. with similar radars for air traffic control, see United States air traffic control radar stations.

United States general surveillance radar stations include Army and USAF stations of various US air defense networks (in reverse chronological order):

• Joint Surveillance System (JSS), with radar stations controlled by joint FAA/USAF ROCCs beginning in 1980
• SAGE radar stations, for the Semi-Automatic Ground Environment network prior to the JSS (the 1st SAGE squadrons were designated in 1958)
• Alaska Ring radar net, the radar stations of Alaskan Air Command
• Permanent System radar stations, the Air Defense Command manual network of radar stations prior to deployment of SAGE
• Pinetree Line, a series of radar stations located across southern Canada at about the 50th parallel north.
• Lashup Radar Network radar stations, the radar stations deployed 1950-2 when the "Radar Fence" Plan was not approved
• Temporary radar net, the "five-station radar net" established in 1948
• Army Radar Stations, World War II installations of the Aircraft Warning Service with radars (cf. filter centers, Ground Observer Corps stations, etc.)

By usage:

• RBS Express sites, temporary stations for Radar Bomb Scoring trains which had AN/MPS-9 general surveillance radars
• Nike Integrated Fire Control sites, with general surveillance radars used to acquire the target (i.e., defense acquisition radar, "ACQR", such as the General Electric AN/MPQ-43 High Power Acquisition Radar)
• Army Air Defense Command Posts, which used general surveillance radars for coordinating fire from several Nike batteries (e.g., FAA Air Route Surveillance Radars at JUSS radar stations like Fort Heath)
