The B-21 Raider is the first new American bomber aircraft in more than 30 years, and almost everything about the development of the aircraft has been kept under wraps.
Those few images reveal that the Raider resembles the black nuclear stealth bomber it will eventually replace, the B-2 Spirit.
While the Raider may resemble the B-2, once you get inside, the similarities stop, said Kathy Warden, chief executive of Northrop Grumman Corp., which is building the Raider. In a fact sheet, Northrop Grumman, based in Falls Church, Virginia, said it is using “new manufacturing techniques and materials to ensure the B-21 will defeat the anti-access, area-denial systems it will face.”“When we talk about low observability, it is incredibly low observability,” Warden said. “You’ll hear it, but you really won’t see it.”
The Raider will not make its first flight until 2023. However, using advanced computing, Warden said, Northrop Grumman has been testing the Raider’s performance using a digital twin, a virtual replica of the one being unveiled. In October 2001, B-2 pilots set a record when they flew 44 hours straight to drop the first bombs in Afghanistan after the Sept. 11 attacks. But the B-2 often does long round-trip missions, because there are few hangars globally that can accommodate its wingspan. That limits where B-2s can land for needed post-flight maintenance. And the hangars needed to be air-conditioned — because the Spirit’s windows don’t open, hotter climates can cook cockpit electronics.
