F18F+
So lets say we do get some (Updated with new motors etc), from a maint point of view a carrier aircraft is built to last (Brick outhouse comes to mind). If flown from land that gives you years of fatique life.
If we do then both the Light and Dark blue could use the same airframes even if the light blue do not fly from the decks.
We used to have a simulated angled deck at at least one airfield so would not be impossible to do again.
The two crew thing. Chap/Chapess in front does that pilot thing which another set of hands 'N' eyes to fight with. Yes in pure A2A single seat is as good(Possibly), but in todays CAS role talking to ground troops watching the pod feed and looking out for the ground at the same time. Now do that at night i think two seat wins. I seem to remember a two seat Fairchild A10- for bad weather night time. Only 1 was made, makes sense though.
