I would rather that the USAF had bought 100 KC-10Bs (my personal designation for Mil-Spec tanker/cargo versions of the MD-11, fitted out as per the KC-10 but updated [the 60 KC-10As were built in the mid-1980s]).
These would be ordered in ~1995, and would be based on the MD-11F freighter, which was the last version in production (last deliveries 2001). They would, in addition to the under-tail hose/drogue unit, have hose pods under the outer wings.
Comparison of MD-11F and DC-10-30F - to the right DC-10-30F, to the left MD-11F (note the cargo door under the "AR" in the airline name).
