The B-21 Raider, the U.S. Air Force’s next generation of stealth bomber, has successfully completed loads calibration testing and is on track to take its first flight next year, according to Northrop Grumman.

The news emerged as Ellsworth Air Force Base, South Dakota—location of the first operational B-21 Raider unit—broke ground last week on a 95,000-square-foot Low Observable Restoration Facility. The facility is the first of more than 30 projects slated for the base to support the aircraft, the Associated Press reported.
