 The B-21 is expected to operate out of bases currently servicing heavy bombers, such as Dyess Air Force Base, Texas, Ellsworth Air Force Base, South Dakota, and Whiteman Air Force Base, Missouri.On 27 March 2019, Ellsworth was selected as the Air Force Base to host the first operational B-21 Raider bomber unit and the first formal training unit.On 31 January 2020, new B-21 renderings were released by the USAF and Northrop Grumman, showcasing the distinctive flush and blended inlets and the two-wheel main landing gear design, potentially indicating the smaller size and weight of the aircraft in comparison to the B-2 Spirit.
