What that looks like and how that evolves.... The Polaris aircraft, for example, were retrofitted for that capability. Again, the Herc-Hs were modified. Fuel bladders are installed so they can be.... I won't say it's simple, but it's a different thing that could be done. Potentially, you even could modify the Herc-Js to pick up some of that.
So is it a bespoke fleet or is it stuff we're doing with existing aircraft? There is thinking around it, led by the air force and our chief of force development, but I would say it's secondary to what direction we take with fighters and where we go.
