Providing Generations of Aircraft with Advanced AESA Capabilities

The AN/APG-83 Scalable Agile Beam Radar (SABR) is an Active Electronically Scanned Array (AESA) fire control radar (FCR). It incorporates advanced technology and capabilities from Northrop Grumman’s family of fifth generation radars including the AN/APG-77 on the F-22 and the AN/APG-81 on the F-35.

SABR was developed to provide the F-16 and other legacy platforms with a cost-efficient AESA modernization option, ensuring fleets remain operationally viable and sustainable for decades to come. Designed with a modular architecture and scalability in mind, SABR can be easily installed and integrated on a wide variety of aircraft with minimal modifications.

Maintaining Operational Relevancy in Highly Contested Environments

To remain relevant in the increasingly lethal and evolving multi-dimensional battlespace, fourth generation platforms need modernized systems, to include advanced AESA sensors.

With SABR, operators can better detect, track, identify and engage a greater number of targets faster, more accurately and at longer ranges compared to mechanically scanned radars. Its electronically scanned beams, processing power and highly advanced modes provide aircrews with improved mission effectiveness, survivability and situational awareness.

The multi-dimensional battlespace has also created complex challenges where aircrews are required to quickly adapt and operate across domains. SABR’s low size, weight and power (low-SWaP) further enhances agility and performance, allowing effective operations in various mission scenarios while ensuring no compromise in capabilities.
