AN/APG-77 AESA Radar

Northrop Grumman Corporation is the world leader in airborne fire control radars and the sole supplier for both USAF fighter platforms of the future: the F-22 Raptor and the F-35 Lightning II. Northrop Grumman is unmatched as the largest producer of airborne fire control Electronically Scanned Arrays (ESAs).

AN/APG 77 AESA radar and the F-22 Raptor

Providing the F-22 Raptor with air-to-air and air-to-ground superiority, the AN/APG 77 AESA radar builds on Northrop Grumman's wealth of design experience with AESA fire control radars and sensors. (SEE RADAR PAGE) Our mature production environment reflects decades of AESA development. We have continuously improved strong designs and reduced the cost while expanding capabilities that are reflected in the AN/APG 77 AESA radar.

This radar provides an unprecedented stealth capability in air-to-air combat, allowing the pilot to track and shoot at multiple threat aircraft before the adversary's radar detects the F-22 Raptor. Solid state-of-the-art technology and elimination of mechanical moving parts enables the AN/APG-77 to leap ahead of standards for system reliability and field sustainability.

Northrop Grumman is responsible for the overall design of the AN/APG-77 radar system, including the control and signal processing software. Northrop Grumman also has responsibility for radar systems integration and test activities.

The main component of the radar sensor is a highly reliable Active Electronically Scanned Array (AESA), which provides the rapid beam agility, low radar cross section and target detection capability that enables the air dominance fighter to achieve "first look, first kill" capability. The system exhibits a very low radar cross section, supporting the F-22's stealthy design.

AN/APG 77 provides superior battlespace situational awareness that translates into lethality and survivability.
