but other platforms might see them
Other than F16/Stealth, where might you expect to see foils?
Would you expect to see lifting foils?
The Stealth uses them on their rudders for stabilization of the platform which seems to be effective, but they don't try to lift the platform out of the water from what I can tell.
If you were to do a "clean sheet" approach to the F16, would you try to incorporate "lifting" foils?
