Radar delivery upgrades USMC F-18 Hornet fleet to AESA radars​

APG-79 installation

EL SEGUNDO, Calif., (April, 29, 2021) – Raytheon Intelligence & Space, a Raytheon Technologies business (NYSE: RTX), delivered the APG-79(V)4 AESA radar prototype to the U.S. Marine Corps. The prototype allows for early flight testing and completion of weapon systems integration on the Hornet platform.

The APG-79(V)4 is a scaled version of the APG-79 AESA radar that helps pilots detect and track enemy aircraft from farther distances and with more accuracy than the legacy APG-73 system. The radar’s improved targeting capabilities provide an edge in crucial operations including air-to-air, maritime strike and air-to-surface missions. Powered by gallium nitride (GaN), the APG-79(V)4 is the first domestic implementation of a GaN-based fire control radar, with GaN Transmit/Receive Modules embedded directly into the array.

“Aircrews must have access to new tools to support readiness,” said Eric Ditmars, vice president of Secure Sensor Solutions for RI&S. “The upgrade to AESA radar offers increased reliability and sustainability for the customer, which equates to lower maintenance and repair costs, and increased aircraft availability.”

The smaller radar shares much of the same parts and technology as the AN/APG-79 radar used in the F/A-18 Super Hornet aircraft.

The first 25 production AESA radars will be delivered starting in December 2021 as part of the $83.6 million production contract awarded in 2020.
