Hundreds and hundreds of millions of dollars so that the sortie rate will rise into the upper 70 to lower 80 percentile. That makes for a logistical nightmare having to schedule two aircraft for high priority cargo. Too bad that the C-17 can't address some of the more esoteric load capabilities of the C-5. However, the debate is whether to use that same money to buy more C-17s (and thus keep the production line open) and perhaps the more outsize cargo addressed by contract use of AN-124s like that in NATO.
