From the online Los Angeles Times, Oct. 8, 2003:

"The Air Force also is considering putting new engines on the B-1 to
double the speed of what is already one of the fastest bombers in the
world."

The link to the whole story follows, but the above sentence is all they
say about the Lancer.

Never heard this one before. I knew the B-1A was faster, and that
engine inlet changes were made to favor low radar cross section over
speed in the B-1B. Can they have speed and stealth nowadays, or will
the faster plane have a more B-1A-like cross section?

TIA.
