Fighters are really redundant.
That is somewhat correct for this particular case (fighters for a naval air wing) in theory provided that you do not want to "project power". If you want to operate strictly from friendly airbases, defend established positions and intercept things coming into "your" airspace you do not need an aircraft carrier and a carrier wing.
Aircraft carriers are purely a tool of power projection so you can do all of the above on the other side of the globe. You also do not know which of all the jobs they will have to do. So you end up using multi-role aircraft. Or so the theory goes. IMHO that theory does not compute for the current cost of 5th generation multi-role fighter aircraft. There is definitely a role for an auxiliary force of something in the SuperTucano class in addition to the jets. They are way too expensive.
By the way, as far as "Civilian intercept by any plane you've got hanging around.", try intercepting a LearJet (15,000m ceiling) or Yak 40 (ridiculous thrust to weight) or An-72 (ridiculously low stall speed). If they have managed to McGuiver an ECM pod to prevent you from locking on, you may find that this statement needs some revising.
