The US Air Force has unveiled a new B-21 stealth bomber which is expected to help strengthen US deterrence against China. An unveiling ceremony was held in California on Friday. The B-21 Raider was developed by US manufacturer Northrop Grumman, which makes the currently deployed B-2 stealth bomber. The company says the new strategic bomber is capable of delivering nuclear payloads and has advanced stealth capabilities which make it difficult for enemy radar to detect it. The aircraft can also be flown without a pilot. Defense Secretary Lloyd Austin noted that the B-21 is the first strategic bomber that the US military has introduced in more than three decades. He said strengthening and sustaining US deterrence is at the heart of the national defense strategy. The administration of President Joe Biden is working to modernize US nuclear capabilities as it remains on heightened vigilance against China's growing nuclear arsenal. The US Air Force plans to bring the B-21 into service in the mid-2020s and maintain a fleet of at least 100. US media say the new bomber is expected to play a core role in deterring China.
