Just check out what this L-1011 can do for Navy. Big monies made by Tempus. This is monster plane.
The TriStar tanker in question is a mult-irole leviathan of the skies. She can seat 266 passengers and can carry a whopping 300,000lbs of jet fuel that can be passed to any aircraft that can keep up with her and is equipped with a standard "hose and drogue" refueling probe.
If you are not interested in refueling everything from Super Hornets to RAF E-3 Sentries, or taking 266 of your friends a third of the way around the world, then you can use the TriStar for hauling outsized cargo, as its massive clam-shell cargo door can swallow anything from cargo containers to Humvees.
