The Solid State Phased Array Radar System [1] (SSPARS, colloquially "BMEWS radar network'" as late as 2004) [2] is a United States Space Force radar, computer, and communications system for missile warning and space surveillance. There are SSPARS systems at five sites: Beale Air Force Base, CA, Cape Cod Space Force Station, MA, Clear Space Force Station, AK, RAF Fylingdales, UK, and Pituffik Space Base, Greenland. [3] The system completed replacement of the RCA 474L Ballistic Missile Early Warning System when the last SSPAR was operational at then-Clear Air Force Station in 2001. [1]

Classification of radar systems

Under the Joint Electronics Type Designation System (JETDS), all U.S. military radar and tracking systems are assigned a unique identifying alphanumeric designation. The letters “AN” (for Army-Navy) are placed ahead of a three-letter code. [4]

The AN/FPS-132 Upgraded Early Warning Radar (UEWR) is a series of phased array radar systems used for long-range early warning and space surveillance, operating as part of the United States Missile Defense and Space Surveillance Network.

Thus, the AN/FPS-132 represents the 132nd design of an Army-Navy “Fixed, Radar, Search” electronic device. [4] [5]

History

The Solid State Phased Array Radar System is a phased array radar with 2500 "solid state transmitter" modules. [6]

It began replacing PAVE PAWS when the first AN/FPS-115 face was taken off-line for the radar upgrade. New AN/FPS-123 Early Warning Radars became operational in (Beale) and (Cape Cod) in each base's existing PAVE PAWS "Scanner Building". [7]

In 2001 SSPARS equipment included:

After the Fylingdales BMEWS radars had been replaced by Raytheon/Cossor AeroSpace and Control Data Corporation (embedded CDC-Cyber computer) at a cost of US $100M,[ citation needed ] in February 1995 the "missile warning center at Cheyenne Mountain AS [was] undergoing a $450 million upgrade program". [15] The entire SSPARS became operational on January 31, 2001 when the "SSPARS Site" [16] at Clear AFS (separate from the BMEWS site) had Initial Operational Capability. [17] The Clear AN/FPS-120 was subsequently "upgraded to the AN/FPS-123 model" SSPA Radar, [18] and the SSPARS was modified in the Early Warning Radar Service Life Extension Program [1] The US approved sale of an[ which? ] AN/FPS-115 to Taiwan in 2000 [19] and it was introduced in 2006. [20]

The UK and Alaska BMEWS stations became SSPARS radar stations when their respective AN/FPS-126 radar [21] and 2001 AN/FPS-120 became operational. [22] In 2007, 100 owners/trustees of amateur radio repeaters near AN/FPS-123 radars were notified to lower their power output to mitigate interference, [23] and AN/FPS-123s were part of the Air Force Space Surveillance System by 2009. [24] BAE Systems began a 2007 contract for SSPARS maintenance. [25] The SSPARS radar electronics was subsequently upgraded, e.g., the Beale radar [19] and the Fylingdales FPS-126 each became an AN/FPS-132 Upgraded Early Warning Radar (UEWR) [26] by Raytheon. [27] The Beale AN/FPS-123 was upgraded to a Raytheon AN/FPS-132 (UEWR) with capabilities to operate in the Ground-based Midcourse Defense (GMD) ABM system—the Beale UEWR included "Avionics", "T/R modules", [28] "FEX/TTG", "BSG", "Signal Processor", and other changes. [29] After additional UEWR installations for GMD at Thule Site J and the UK (contracted 2003), [30] a 2012 ESD/XRX Request for Information for replacement, and remote operation, of the remaining "PAVE PAWS/BMEWS/PARCS systems" at Cape Cod, Alaska, and North Dakota was issued. [31] The Alaska AN/FPS-132 was contracted in fall 2012 [32] and the Cape Cod installation in 2013. [19]

The AN/FPS-132 Block-5 was ordered by the Qatar Emiri Air Force, and is in construction. [33]

<span class="mw-page-title-main">PAVE PAWS</span> Early warning radar

PAVE PAWS is a complex Cold War early warning radar and computer system developed in 1980 to "detect and characterize a sea-launched ballistic missile attack against the United States". The first solid-state phased array deployed used a pair of Raytheon AN/FPS-115 phased array radar sets at each site to cover an azimuth angle of 240 degrees. Two sites were deployed in 1980 at the periphery of the contiguous United States, then two more in 1987–95 as part of the United States Space Surveillance Network. One system was sold to Taiwan and is still in service.

The RCA 474L Ballistic Missile Early Warning System was a United States Air Force Cold War early warning radar, computer, and communications system, for ballistic missile detection. The network of twelve radars, which was constructed beginning in 1958 and became operational in 1961, was built to detect a mass ballistic missile attack launched on northern approaches [for] 15 to 25 minutes' warning time also provided Project Space Track satellite data.

<span class="mw-page-title-main">Active electronically scanned array</span> Type of phased array radar

An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).

Royal Air Force Fylingdales or more simply RAF Fylingdales is a Royal Air Force station on Snod Hill in the North York Moors, England. Its motto is Vigilamus. It is a radar base and is also part of the Ballistic Missile Early Warning System (BMEWS). As part of intelligence-sharing arrangements between the United States and United Kingdom, data collected at RAF Fylingdales are shared between the two countries. Its primary purpose is to give the British and US governments warning of an impending ballistic missile attack. A secondary role is the detection and tracking of orbiting objects; Fylingdales is part of the United States Space Surveillance Network. As well as its early-warning and space-tracking roles, Fylingdales has a third function – the Satellite Warning Service for the UK. It keeps track of spy satellites used by other countries, so that secret activities in the UK can be carried out when they are not overhead. The armed services, defence manufacturers and research organisations, including universities, take advantage of this facility.
