The AN/APG-83 Scalable Agile Beam Radar (SABR) is a full-performance active electronically scanned array fire control radar for the General Dynamics F-16 Fighting Falcon and other aircraft developed by Northrop Grumman. SABR is a multi-function active electronically scanned array (AESA) radar.[1] In a 2013 competition, Lockheed Martin selected SABR as the AESA radar for the F-16 modernization and update programs of the United States Air Force and Republic of China Air Force.[2] 5th Generation Fighter Radar Capability for the 4th Gen Aircraft. The SABR APG-83 is an Active Electronically Scanned Array (AESA) fire control radar.

The capabilities of this advanced AESA are derived from the F-22's AN/APG-77 and the F-35's AN/APG-81. It is designed to fit F-16 aircraft with no structural, power or cooling modifications.[3] The SABR is scalable to fit other aircraft platforms and mission areas.

In 2010, a SABR was installed on a USAF F-16 at Edwards AFB and flew 17 consecutive demonstration sorties without cooling or stability issues.[4]

In addition to equipping F-16V for Taiwan and other US allies, US Air Force also selected APG-83 SABR to upgrade 72 of its Air National Guard F-16s.[5]

In January 2014, Singapore ordered 70 AN/APG-83 SABR for its 60 F-16C/D/G+ Block 52 upgrade, in a $2.43 billion deal.[6][7][8]

At August 2018, Northrop Grumman conducted an APG-83 fit test on an F-18.[9]

A derivative of the AN/APG-83, the SABR-GS (Global Strike), will be fitted to the Rockwell B-1 Lancer beginning in 2016.[10][11][12]

In February 2019, Northrop Grumman offered SABR for retrofitting Boeing B-52H Stratofortress, which currently uses mechanically scanning AN/APQ-166 attack radar.[13] In July 2019, Boeing selected AN/APG-82(V)1/(AN/APG-79) from Raytheon for its B-52H radar modernization program.[14]

Northrop Grumman to offer SABR radar for Seoul's FA-50 Block 20 fighter.[15][16]

The US Air Force is installing the AN/APG-83 SABR on 608 of its F-16C/D Block 40/42 and F-16C/D 50/52 fighters.[17][18]
