Northrop Grumman has introduced its Scalable Agile Beam Radar – Global Strike (SABR-GS) developed for the US Air Force B-1B Lancer. The development of the radar has taken place under a $21 million risk reduction contract awarded in 2011 by the US Air Force B-1 Systems Program Office.
The SABR-GS is a full performance, multi-function, Active Electronically Scanned Array (AESA) radar developed as a low-risk radar retrofit solution. It offers improved operational capabilities and system reliability over the legacy passive ESA.
The AESA radar features large synthetic aperture radar maps, advanced image processing and sensor integration for new capabilities for intelligence, surveillance, reconnaissance and targeting. Open architecture standards have also been used to integrate data from other on-board sensors.
The SABR-GS is a derivative of the AN/APG-83 SABR. It builds on hardware, legacy modes and advanced operating modes proven on the F-35, F-22 and F-16 aircraft.
With the radar's advanced B-1 AESA and advanced sensor and fusion processing demonstrated in flight, the company is readying it for the engineering, manufacturing and development phase.
Paul Kalafos, vice president, surveillance systems business unit, Northrop Grumman, said: 'By developing SABR-GS, we've enabled capabilities now critical to the mission – a significant milestone for SABR technology and the B-1.
'By leveraging the successes of the SABR for the F-16 fighter, we have activated cost savings for the US air force's B-1 programme, proven that SABR AESA technology is scalable and extended the survivability of the aircraft for the next 25 years.'
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
The Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) counter-improvised explosive device (C-IED) and Drone Restricted Access Using Known Electromagnetic Warfare (DRAKE) counter-UAS (CUAS) systems are mounted and dismounted RF jammers.
Adarga’s Vantage information analysis tool is in service with the UK MoD and individual UK forces. It builds on the company’s Knowledge Platform which processes, organises and analyses open source material, as well as information held by the user’s military, security and intelligence services.
