System Designed To Replace Mechanical-Scan Radars In F-16s

Northrop Grumman announced this week it recently conducted the first successful demonstration flight of the company’s newest Active Electronically Scanned Array (AESA) fighter sensor, the Scalable Agile Beam Radar (SABR). SABR is being developed as a significant avionics enhancement for the existing fleet of F-16s and other fighter aircraft worldwide.

"This first flight marks a major milestone in our effort to develop an AESA radar designed specifically to meet current F-16 power, cooling, and interface requirements," said Arlene Camp, director of Advanced F-16 Radar Programs at Northrop Grumman. "Although designed specifically for the F-16, SABR is scalable and adaptable to other platforms and missions."

SABR completed its first flight ahead of schedule on November 16, in the nose of (appropriately enough) a Rockwell Sabreliner. Camp said the new radar system successfully detected and displayed numerous aerial targets, exceeding first flight predictions.

"This demonstration flight is the first in a series scheduled over the next few weeks as we transition SABR from a laboratory environment to an operational flight environment," she said. "The Sabreliner testbed aircraft has an actual F-16 radome and avionics. We've used the Sabreliner for more than 20 years for developing and testing F-16 mechanically scanned radar hardware and software. It's as close as you're going to get to a real F-16 flight demonstration."

"SABR is Northrop Grumman's investment toward enhancing and sustaining the F-16's combat capability for decades to come," added Camp. "We plan to demonstrate SABR on an F-16 next year."

Northrop says that compared to the mechanically-scanned array radars it is designed to replace, SABR will provide the increased performance, multi-functionality, and greater reliability inherent in AESA radars. The improved situational awareness, greater detection, high-resolution synthetic aperture radar, and interleaved air-to-air and air-to-surface mode operations will provide pilots true all-environment precision strike capability.
