I should not have said "missile base". I just meant any kind of forward base outside the US.
The B-52, etc.. is just different. It's not as high value of an asset as the B-2 or the B-21 will be and gets treated differently.
The Air Force already periodically deploys B-2's to forward bases within range of Chinese missile strikes.

Current plans are to purchase a relatively large number of B-21's. Some losses are expected and accepted.
Not a "missle base", but: "The B-52...is one of two currently at RAF Fairford in England as part of a routine Bomber Task Force (BTF) deployment." [0]
Also, more pertinent to location in scope, US has been increasing forward-based capabilities in south pacific, for example [1].
