The AN/APG-79 is a variant of an active electronically scanned array (AESA) radar developed for the United States Navy's Boeing F/A-18E/F Super Hornet and Boeing EA-18G Growler aircraft, providing a high level of aircrew situational awareness. The beam of the AESA radar provides fast track updates and multi-target tracking capability. The APG-79 AESA uses transmit/receive (TR) modules populated with Gallium arsenide Monolithic microwave integrated circuits.[1] In the F/A-18E/F, the radar is installed in a slide-out nose rack to facilitate maintenance.

The APG-79 features an entirely solid-state antenna construction, which improves reliability, durability, and reduces the cost compared to a traditional radar system.[2]

The radar has a range of up to 150 km (80 nm) and multi-target tracking capabilities.[3]

The APG-79 is compatible with current F/A-18 weapon loads and enables aircrew to fire weapons such as the AIM-120 AMRAAM,and simultaneously guide several missiles to several targets widely spaced in azimuth, elevation or range.

The APG-79 radar completed formal operational evaluation (OPEVAL) testing in December 2006. As of January 2007, the radar was installed in 28 aircraft; some were experiencing software problems but that issue was expected to be resolved by the end of fiscal year 2007.[4] As of July 2008, Raytheon had delivered 100 APG-79 sets to the United States Navy; on 3 June 2008, the Navy received the first APG-79-equipped Boeing EA-18G Growler. The Navy expects to order approximately 437 production radars.[5]

In January 2013, the Director, Operational Test & Evaluation (DOT&E) disclosed a long history of problems for the APG-79 radar in initial operational testing.[6]

In December 2020, Raytheon offered AN/APG-79 for retrofitting the F/A-18 C/D.[7] In July 2021 the United States Marine Corps selected AN/APG-79(V)4 with gallium nitride (GaN) transmitters to upgrade their fleet of F/A-18 fighters.[8] The new radar was flight-tested in May 2022.[9]

The APG-79B4 version is slated to be installed inverted on the B-52 during its Commercial Engine Replacement Program (CERP)[10][11][12]

In 2022 Malaysia chose the APG-79(V)4 for an F/A-18C/D Hornet upgrade and the newly developed FA-50 Golden Eagle[13]
