Why The US Air Force Is Turning The B-21 Raider’s Test Jets Into Its 1st Combat Bombers

The United States Air Force has a couple of test Northrop Grumman B-21 Raiders that are blurring the line between testing and fielding. The B-21 Raider is expected to enter service in 2027, making it the world’s first all-new strategic bomber to enter service since the B-2 Spirit entered service in 1997. China is also working to develop its Xi’an H-20 stealthy strategic bomber, but it is unclear when it will enter service.
