Raytheon delivered the first prototype of the new AESA (active electronic scanning) radar APG-79(V)4 to the US Marine Corps (USMC) on April 29th. The sensor will be equipped on F/A-18C/D Hornet fighters. Delivery of the radar prototype allows for early flight testing and completion of the integration of weapons systems on the Hornet platform.
The APG-79(V)4 is a scaled version of the APG-79 radar already used on the F/A-18E/F Super Hornet, sharing technology and a large number of parts used in the previous version. Its biggest difference is the use of gallium nitride (GaN) transmission/reception modules, increasing the system's operating speed and allowing greater detection and tracking distance for enemy aircraft.
The new feature also represents the first use of GaN on a US fire control radar. The APG-79(V)4 is much more agile and capable than the APG-73 currently in use on Hornets.
The radar's enhanced targeting capabilities provide an advantage in critical operations, including air-to-air, maritime attack and air-to-surface missions, says the manufacturer.
“Crews must have access to new tools to readiness,” said Eric Ditmars, vice president of Secure Sensor Solutions at Raytheon Intelligence & Space.
“Upgrading to AESA radar offers greater reliability and sustainability for the customer, which equates to lower maintenance and repair costs and increased aircraft availability.”
According to Raytheon, the first 25 production AESA radars will be delivered to the USMC starting in December 2021, as part of the $83,6 million production contract awarded to the manufacturer last year.
