US Air Force via AP hide caption toggle caption US Air Force via AP US Air Force via AP WASHINGTON — America’s newest nuclear stealth bomber makes its public debut after years of secret development and as part of the Pentagon’s response to growing concerns about 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 show is classified. Ahead of its unveiling Friday at an Air Force facility in Palmdale, California, only artist renderings of the fighter jet 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 bomber is part of the Pentagon’s efforts to modernize all three legs of its nuclear triad, which includes silo-launched nuclear ballistic missiles and submarine-launched warheads, as it transitions from the counterterrorism campaigns of past decades to rapid military modernization. from China. China is on track to have 1,500 nuclear weapons by 2035, and its achievements in hypersonics, cyber warfare, space capabilities and other areas present “the most significant systemic challenge to US national security and the free and open international system.” the Pentagon said. this week in its annual China report. Defense Secretary Lloyd Austin and other guests will be on hand Friday to witness the public unveiling of the bomber. “We needed a new bomber for the 21st century that would allow us to deal with much more complicated threats, like the threats that we fear one day facing from China, Russia,” Deborah Lee James, Secretary of the Air Force, said when the Raider contract was announced. in 2015. “The B-21 is more survivable and can take on these much tougher threats.” While the Raider may look like the B-2, once you get inside, the similarities disappear, said Kathy Warden, chief executive of Northrop Grumman Corp., who is building the Raider herself. “The way it operates internally is extremely advanced compared to the B-2, because the technology has evolved so much in terms of computing power that we can now integrate into the B-21 software,” Warden said.
