The US Air Force unveiled its world's first sixth-generation nuclear stealth bomber plain, the B-21 Raider. It has a 9,600-kilometre range and roughly 10-ton payload, though, as expected, further specific details have not been revealed.
The ceremony took place at manufacturer Northrop Grumman's facility in Palmdale, California.

The B-21 Raider has been known to be developed as a subsonic aircraft and not meant for the tight maneuvers of a fighter. At the unveiling ceremony, US Defence Secretary Lloyd Austin said it was "a testament to America's enduring advantages in ingenuity and innovation".
The first flight by a B-21 is expected to take place next year.
The US Air Force is planning to acquire at least 100 of the aircraft.

The B-21 features stealth technology, which minimises an aircraft's signature through both its shape and the materials it is constructed from, making it harder for adversaries to detect.
The plane is also built with an "open system architecture," which allows for the incorporation of "new weapons that haven't even been invented yet," Austin said.

The B-21 will eventually replace the B-1 and B-2 models and the fleet is estimated to cost $203 billion to develop, buy and operate over 30 years, according to Bloomberg.
With B-21, Pentagon aims to modernise all three parts of its nuclear triad, including silo-launched nuclear ballistic missiles and submarine-launched warheads, as it shifts from the counterterrorism campaigns of recent decades to meet China’s rapid military modernization, reports AP news agency

US has been keen on neutralising China's reach in major US bases. Beijing has DF-16, DF-17, DF-21, DF-21D, and DF-26 missiles, which have the capability to strike any US base in the Pacific.
The B-21 Raider has been designed to participate in the full scale war, along with the B-2 Spirit, B-1 Lancer, and B-52s.
In a statement given to Air and Space Forces Magazine, Northrop Grumman said that the Raider “has been designed as the lead component of a larger family of systems that will deliver intelligence, surveillance and reconnaissance, electronic attack and multi-domain networking capabilities.”
