Just a note B-1 Bomber is not stealth.
BONE wasn't advertised as stealthy, but the basic design resulted IIRC in a radar signature (for equipment in the 70's) about the size of a hawk. (The B-52's is/was more on the scale of a billboard---too many large almost flat surfaces.)
Also and in addition to an already quite extensive electronics capability (radar detection/jamming etc) designed into the B-1A, there were whole frame sections in the aft fuselage that only showed on drawings and the full-scale mockup used to verify parts locations/cable runs as "Reserved for future systems growth".
Considering the amount of miniaturization in electronics since I last worked on that bird, even if those voids were only fractionally used, the BONE today would have to pack a very serious counter-radar punch indeed.
I wouldn't like to be any OPFOR Anti-aircraft site with either BONE or Spirit coming at me no matter what the media called 'em.
