"WASHINGTON (AP) — America’s newest nuclear stealth bomber is making its public debut after years of secret development and as part of the Pentagon’s answer to rising concerns over a future conflict with China.
The B-21 Raider is the first new American bomber aircraft in more than 30 years. Almost every aspect of the program is classified. Ahead of its unveiling Friday at an Air Force facility in Palmdale, California, only artists’ renderings of the warplane have been released. Those few images reveal that the Raider resembles the black nuclear stealth bomber it will eventually replace, the B-2 Spirit."

"“The way it operates internally is extremely advanced compared to the B-2, because the technology has evolved so much in terms of the computing capability that we can now embed in the software of the B-21,” Warden said.
Other changes likely include advanced materials used in coatings to make the bomber harder to detect, new ways to control electronic emissions, so the bomber could spoof adversary radars and disguise itself as another object, and use of new propulsion technologies, several defense analysts said.
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.”"
