That's a total fuel load-not a giveaway! Not sure about the burn for the Osprey but it is hard to see an offload of 4000lbs per AC for a 4 ship on even a short sortie. Question then is would the Rx have room? If the Osprey had to go further to allow room for the fuel then the offload available goes down. On the other hand, I can see value for the AC as a tanker to cover recoveries.
