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.

I don't want to know everything this cool bomber can do, because then my enemies would know, too. In addition, then you'd have to kill me, and all your viewers.
By “breaking“ and “just” I assume you mean two weeks ago when I heard about this flight on every other aviation news source I know of.
The B-21 has been flying for more than a year .
It not really a big brother its more like a little sister:)
