Never heard it put that way before, but the problem with that is, that B-1s turn like an old car missing three wheels. Which is to say, they will be lucky to pull out of the dive. Especially after being shot at. And as for the whole stealth thing, Doppler Effect is still a thing. I may not be an aeronautical engineer, but I have lived next to an AFB my entire life. The Zoomies, regardless of how fast they're going, even over Mach 1, can still be heard, because of the noise of the sonic boom. And these are F-22s and -16s, and they're kind of easy to pick out of the southern New Mexico sky. A B-1, over the ocean, I'd imagine, is probably easy as well, though I don'tknow for sure..
