B-21 Raider covertly completes preliminary design review: The US Air Force’s new B-21 bomber stealthily hit a milestone recently, wrapping up its preliminary design review.
During a House Armed Services Committee hearing on nuclear deterrence, Gen. Stephen Wilson, the Air Force’s vice chief of staff, told lawmakers that he receives regular updates on the uber-classified program and is happy with its progression.
“They just finished a preliminary design review recently,” he said. “It's making great progress, and we’re pleased with the way it’s headed."
The Air Force awarded Northrop Grumman a contract to develop and produce the B-21 Raider in October 2015. The company beat out a Boeing-Lockheed Martin team, a decision that was sustained even after the losing competitors filed a protest with the Government Accountability Office.
