The US Air Force (USAF) announced on 24 March that the service proceeds with integration work of the active electronically scanned array (AESA) Northrop Grumman AN/APG-83 Scalable Agile Beam Radar (SABR) aboard the Lockheed Martin F-16 Fighting Falcon. The service is now conducting developmental tests according to the announcement.
SABR is able to be fitted without any major modifications to the structure of the aircraft. The first SABR equipped F-16 flew in 2010.
