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.

I’m not worthy! Thank you for your service. My dad shot rockets off in the Pacific in the early 60s.
