Actually somebody almost brought up a GREAT use for them..... resupplying a carrier.
We could fly them from land base, land them in water within carrier group (its sphere of influence). And then with a return to tower, you've resupplied the carrier. That or have them land and then have to sit in the area for a while (kinda like rearming pads, except reversed) until a little text message pops up saying "Carrier resupplied" It would require a bit of skill, since the pilot would have to land in such a place that they will stay within the carriers "sphere of influence" for the entire rearming, as well as it would be difficult should the carrier run them down doing maneuvers during a big fight.
