BAE Systems will provideĀ Northrop Grumman electronic support measure systems for 20 B-2 bombers, BAE announced Thursday.
Under the contract BAE will replace the aircraft's 30-year-old legacy AN/APR-50 systems.
The systems detect electronic threats and the Air Force uses them on the F-22 and F-35 aircraft.
Brian Walters, BAE vice president and general manager for electronic combat solutions, said the B-2 must have stealth, mission planning and situational awareness capability for crews to complete their missions.
BAE will perform work in Nashua, N.H. and Cambridge, Mass.
Northrop is the prime contractor for all B-2 modernization efforts.
