The Northrop Grumman AN/APG-83 Scalable Agile Beam Radar (SABR) is a full-performance fire control radar for the General Dynamics F-16 Fighting Falcon and other aircraft. 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 (Taiwan) Air Force.[2]

The capabilities of this advanced AESA are derived from the F-22's APG-77 and the F-35's 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.[citation needed]

In 2010, SABR was installed on a USAF F-16 at Edwards AFB and flew 17 consecutive demonstrations 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] At August 2018, Northrop Grumman had APG-83 fit-in test on F-18[6] A derivative of the AN/APG-83 SABR, SABR-GS (Global Strike) will be retrofitted to airworthy Rockwell B-1 Lancer airframes beginning in 2016.[7][8][9]
