Raytheon Intelligence & Space (RI&S) successful conducted the first flight of its pre-production radar system APG-79 (V) 4 with active electron scanned array (AESA).

The radar flies multi-purpose F / A-18 Hornet aircraft of the United States Marine Corps (USMC) at the Naval Air Weapons Station in China Lake, California.

During the flight test, USMC pilots demonstrated the integration of the radar system with classic Hornet avionics.

The final stage comes after the delivery of the prototype of the radar system in 2021.

The company received a contract in 2019 to provide the APG-79 (V) 4 radar system for USMC’s Hornet fleet.

Thomas Shoret, vice president of RI&S F / A-18 and Global Strike Radars, said: “After successful ground tests and the delivery of a prototype radar, this flight test was crucial for monitoring airborne performance.

“This allowed our partners to see improved V4 radar detection and tracking capabilities in real time.”

Raytheon’s APG-79 (V) 4 is a derivative of the APG-79 radar system. It features the first AESA gallium nitride (GaN) fire control technology.

GaN-AESA radar helps pilots identify and track enemy aircraft from long distances with greater accuracy, while meeting the power and cooling requirements of the aircraft.

The new APG-79 (V) 4 radar system is similar in technology and components to the current AN / APG-79 radar used in the USMC F / A-18 Hornet fleet.

This makes the integration of a new radar system more cost-effective and easier to maintain.

Last year, the U.S. Naval Air Command ordered a further modification of the contract to provide more radars for the Hornet fleet.

The total value of the production has reached more than 300 million dollars, which includes local and foreign customers for the sale of military.
