What the AN/FPS-132 Actually Does
The AN/FPS-132 is not an ordinary radar. It belongs to a small family of strategic early warning systems — the kind that exist to give a nation minutes of warning before a ballistic missile arrives. The United States operates a handful of these systems worldwide: at Thule in Greenland, Clear in Alaska, Cape Cod in Massachusetts, Fylingdales in the United Kingdom, and at Al Udeid in Qatar. Each one watches a different arc of the sky. Together, they form an unblinking ring around the globe.
Related Questions
What is the AN/FPS-132 radar?
The AN/FPS-132 Block 5, also called SSPARS, is a strategic early-warning radar built by Raytheon. It uses three electronically steered phased-array faces for 360-degree coverage and can detect ballistic missiles out to about 5,000 kilometres. Its job is to give a nation minutes of warning before a ballistic missile arrives, while also cueing missile defences and tracking objects in space.
How much does an AN/FPS-132 radar cost?
The AN/FPS-132 sold to Qatar cost about $1.1 billion in 2013, closer to $2.1 billion in 2026 dollars. It is not an off-the-shelf item — Raytheon builds these systems on multi-year production timelines, so a heavily damaged array can take months to years to restore to full capability.
What does a missile early-warning radar do?
An early-warning radar detects incoming ballistic missiles at long range and passes that data to interceptor systems, giving them precious extra seconds to react. Without it, defences such as THAAD, Patriot, and Aegis lose their long-range cueing and must rely on shorter-range sensors, compressing warning timelines and reducing their effectiveness.
Where are US ballistic-missile early-warning radars located?
The United States operates a small family of strategic early-warning radars positioned around the globe, including sites at Thule in Greenland, Clear in Alaska, Cape Cod in Massachusetts, and Fylingdales in the United Kingdom. Together they form an unblinking ring designed to detect ballistic missiles approaching from any direction.
What is THAAD?
THAAD (Terminal High Altitude Area Defense) is a US missile-defence system that intercepts ballistic missiles in their terminal phase. It depends on long-range early-warning radars for cueing data; without that feed, its reaction time shrinks. THAAD hardware is highly sensitive — a THAAD seeker was once found intact in the Syrian desert.
Why was the strike on the Al Udeid radar significant?
Degrading the AN/FPS-132 at Al Udeid Air Base forced US Central Command to operate with compressed missile-warning timelines, weakening the cueing that Patriot, THAAD, and Aegis batteries rely on. It also highlighted how exposed advanced US sensors can be — much like when America's secret missile technology was found intact in Syria.
