I wonder if they could make version where the wings fold up, and make it submarine launchable. It would be nice to have a modern-day verison of the Japanese WW2 I-class submarine-carrier
you would have to have a flight deck. Not impossible, but space is at a premium on a sub. The old Jap method was to fill every space inside the aircraft with oil and bolt it to the outside of the sub. Not a low drag way to go.
You could, but why bother -- it has a 1200 mile combat radius with a 4500 lb payload.
