Am I missing something? The B-21 will replace the B-1. The B-1 is supersonic. Does this suggest the B-21 will be supersonic as well.
The article says: “A concept image of the Raider released in early 2016 shows a similar design to the B-2, suggesting the new bomber will be an upgraded B-2 design that “allows for the use of mature systems and existing technology,” according to an Air Force statement.”
What does it mean?
