Due to the commonality and modularity of the F-22/F-35 the latter is in fact a naval variant of the F-22. The F-35 is cheered and geared for a primary air to ground focus with air to air being a secondary role. I can't help but imagine there will be a number of craft modified for a primary air to air role. If you can't protect the fleet you can't bust the ground with ships on the bottom.
