Carriers have TACAN approaches that usually incorporate a marshalling stack off a DME arc. ACLS (Automatic Carrier Landing System) uses radar and a data link to provide vertical/lateral guidance to the deck. The ACLS can also be used to "hand-fly" using a display that looks similiar to an ILS, but projected on the HUD. Finally, a CCA (Carrier controlled Approach) can be used which is very similar to a PAR/GCA. So, lots of ways to make it aboard for mid-rats!

Pretty good except you left out the ICLS which is a carrier version of an ILS (not compatible). In a hornet, the ILS looks like a ILS needles and is called "bullseye" and the ACLS looks like a bullseye and is called "needles." I'm sure it made sense back in the day on some old jet.
