Northrop Grumman Delivers 500th AN/APG-81 AESA Radar for F-35 Lightning II

Northrop Grumman Corporation has delivered its 500th AN/APG-81 active electronically scanned array (AESA) fire control radar for the F-35 Lightning II stealth fighter aircraft, the company announced.

The Northrop Grumman AN/APG-81 is the cornerstone of the F-35’s advanced sensor suite, providing unparalleled battlespace situational awareness that translates into platform lethality, effectiveness and survivability.

“As a principal member of the Lockheed Martin-led F-35 industry team, our continued investment in facilities and equipment, production enhancements in process and design, and expanded supply chain capability through second sourcing helped reach this milestone,” said Chris Fitzpatrick, director, F-35 programs, Northrop Grumman. “The 500th delivery of this top-of-the-line fighter radar was made possible by our continuous focus on quality and excellence across our company.”

The AN/APG-81 radar has long-range active and passive air-to-air (A2A) and air-to-ground (A2G) modes that support a wide range of demanding missions. These modes are complemented by an array of stealth features as well as electronic warfare (EW) and intelligence, surveillance and reconnaissance (ISR) functions.

Northrop Grumman plays a key role in the development, modernization, sustainment, and production of the F-35. In addition to producing the AN/APG-81 radar, the company manufactures the center fuselage and wing skins for the aircraft, produces and maintains several sensor systems, avionics, mission systems, and mission-planning software, pilot and maintainer training systems courseware, electronic warfare simulation test capability, and low-observable technologies.
