Northrop Grumman and Raytheon have been awarded contracts worth an initial $56.2 million to design and integrate a new radar antenna on the B-2 stealth bomber.
Northrop Grumman’s Integrated Systems sector has been awarded a $34.2 million contract by the US Air Force for the first phase of the B-2 radar Pathfinder program, a multiyear effort to design and integrate a new radar antenna on the B-2 stealth bomber.
The total program value for Northrop Grumman, prime contractor for the B-2 program, is estimated at more than $900 million. Installation of the radar antenna on the B-2 fleet is scheduled to be completed by the end of this decade.
Raytheon, which provided the original B-2 radar, has been awarded a $22 million contract as principal subcontractor to Northrop Grumman on the radar program.
The total program value to Raytheon is approximately $575 million, including the remaining development work and the upcoming production contract.
The effort on the B-2 radar upgrade began last year with a study contract defining two alternatives the US government could pursue to change the radar operating frequency while remaining within the existing frequency band.
The US Air Force stated it chose the AESA option because of the inherent reliability and growth potential it offered.
