Almost every aspect of the program is classified.
"We needed a new bomber for the 21st Century that would allow us to take on much more complicated threats, like the threats that we fear we would one day face from China, Russia, " said Deborah Lee James, the Air Force secretary when the Raider contract was announced in 2015. "The B-21 is more survivable and can take on these much more difficult threats."
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. Northrop Grumman’s B-21 Raider will be unveiled on Dec. 2, 2022, at the company’s site in Palmdale, Calif., marking the first time the world’s first sixth-generation aircraft will be seen by the public.
The B-2 was also envisioned to be a fleet of more than 100 aircraft, but the Air Force ultimately built only 21 of them, due to cost overruns and a changed security environment after the Soviet Union fell. 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.
