Regardless, the B-21 Raider is set to become a key component of America's strategic bomber force, alongside
re-engined and
otherwise upgraded B-52 bombers, for decades to come, providing both nuclear deterrent and conventional strike capabilities. Air Force officials have made clear in the past that they see the Raider
as being particularly essential to
ensuring America's deterrent capabilities in the face of
China's growing strategic arsenal. It is also a centerpiece of America's conventional weapons strategy in countering China militarily over great distances in an anti-access/area-denial combat environment like what could be experienced in a future war in the Pacific.
The Air Force expects to ultimately replace all of its
existing B-2 Spirit stealth bombers, as well as
its swing-wing B-1s, with B-21s in the coming years. The service hopes to begin receiving operational Raiders in the mid-2020s, with the first squadron of these bombers to be based at Ellsworth Air Force Base in South Dakota. Additional units will follow at
Whiteman Air Force Base in Missouri and Dyess Air Force Base in Texas.
