The Defense Security Cooperation Agency (DSCA) said it notified Congress Monday of a possible foreign military sale (FMS) to Qatar of one A/N FPS-132 Block 5 Early Warning Radar (EWR) and associated parts and support worth an estimated $1.1 billion.

The proposed sale would also include a prime mission equipment package, technical and support facilities, communication equipment, encryption devices, and spare and repair parts, among others.

The AN/FPS-132 radar provides modernized hardware and software to improve midcourse ballistic missile defense sensor coverage and provide critical early warning, tracking object classification and cueing data, according to the Missile Defense Agency (MDA). The AN/FPS-132 is a solid-state, phased array, all-weather long-range radar. It also detects sea-launched ballistic missiles or ICBMs and provides threat ballistic missile tracking data to commit the launch of interceptors. It can also update the target tracks to the interceptor while it is in flight.

The AN/FPS-132 also detects objects out to 3,000 miles and operates in the ultra high frequency (UHF) band.

The deal is contingent on Congress’ approval.
