After three decades of waiting, it’s finally here — the big brother to the B-2 Spirit and now the world’s most lethal, most groundbreaking next-generation stealth bomber, welcome to the era of the B-21 Raider. The perfect embodiment of a century of technological advancements, the B-21 was built by Northrop Grumman in close partnership with the US Air Force and with more than $11 billion in funding — that’s more funding than it would take to build both of the UK’s most-advanced Queen Elizabeth-class aircraft carriers. Within the past year, this technological wonder of an aircraft has been unveiled in its full glory and more importantly, has just taken flight.
