I know the original was designed to fly fast and low to make it hard to track and shoot at in a pre-stealth world, but then got modified to reduce radar signature at the cost of nearly half its speed (both because of the advent of reliable stealth technology and because the fast-&-low approach was found not to be as effective as expected). But exactly what were those changes and why did they have to compromise speed? I've seen some pictures of B-1A and don't notice anything different about its shape from B-1B. Is it entirely because of what they did to the airflow into the engines to hide the fans in front, or are there also changes to the body and control surfaces that I haven't spotted yet? And are radar-absorbing materials used at all?
