Scalable Agile Beam Radar - Global Strike (SABR-GS) AESA for the B-1B

SABR-GS AESA radar for the B-1 bomber

Supporting the global strike mission for the next 30 years

As the provider of the B-1’s radar for more than three decades, Northrop Grumman has a deep understanding of the aircraft and its demanding global strike mission. Maintaining the B-1’s dominance in the face of growing threats points to the need for a significant increase in capability that only active electronically scanned array (AESA) technology can provide.

  • Faster ground searches: SABR-GS’s electronically scanned beams enable much faster ground searches, resulting in earlier and longer range target detections and tracking, a key operational need for the B-1 bomber.
  • Synthetic Aperture Radar (SAR) mapping and processing: SABR-GS will provide the most detailed SAR maps ever available from a B-1 radar. Northrop Grumman’s image and video processing algorithms automatically scan entire SAR maps, precisely locating and classifying targets of interest and greatly reducing workload.
  • Multiple modes: SABR-GS incorporates proven hardware and operating software modes from Northrop Grumman’s F-35 and F-22 AESA radars, as well as hosting new modes unique to the B-1. Approximately 85% of SABR-GS’s new mode software suite comes directly from the AN/APG-81 radar.
  • Open architecture processing: The new SABR-GS architecture, along with the currently fielded AN/ APQ-164 Radar Reliability and Maintainability Program (RMIP) backend, uses open architecture standards to manage data from multiple sensors. These open architecture principles enable continued innovation and affordability for the life of the system. Advanced video processing allows for interleaved radar modes, moving maps and EO/IR imagery.
  • Survivability: SABR includes robust and proven electronic protection to counter advanced threats.

Maximum performance, reduced cost

With SABR-GS, economies of scale and advanced technologies make exceptional performance affordable. SABR-GS will share an assembly facility, selected parts and a unified logistics network with other Northrop Grumman radars. As an AESA radar with solid state components and no moving parts, the system is projected to be up to seven times more reliable than a mechanically scanned radar. Software commonality with the AN/APG-83 SABR and the F-35’s AN/APG-81radar will further reduce costs and enhance interoperability and supportability within the bomber fleet.
