The radar to be installed is the AN/APG-83 scalable agile beam radar (SABR) from the Northrop Grumman Corp. Electronic Systems segment in Baltimore. Northrop Grumman's SABR is a full-performance fire-control radar that offers all the advantages of an AESA array, but at significant cost savings, company officials say. The radar upgrade will ensure compatibility with fifth-generation fighter fleets around the world.

It optimizes radar system performance within existing power and cooling allocations of legacy F-16s of Taiwan and the U.S. Air Force, and began flying in 2008. SABR will be part of an upgrade to 144 F-16A/B models operated by Taiwan.
