I can only assume you've picked up the old Revell SCB-125 box scale kit...so you've already run into a couple of problems...Antietam never received any of the SCB refits, although she did get an angled deck, it was not considered part of the SCB-125 modernization program. As a result, she did not get an enclosed bow, and she didn't have her 5in. turrets removed. You've got an oddball ship to model, since the Revell kit is the SCB-125 with all of the changes noted above.
You r best best would be to get your hands on an old Lindbergh Essex kit (1/525), and mix and match parts to get what you need....insofar as aircraft are concerned, between '59 and '61she was used as a training carrier, so she carried T-2s, T-28s, S-2s, and most like AD-1s...
No one, to my knowledge, has ever done any aftermarket parts for this kit that I'm aware of, although with this scale (1/535th) you can use the Gold Medal Model photoetch set for the Midway/Forrestal Class. The model was released numerous times over the years with a variety of aircraft, including:
an ASW set, including E-1 Tracers, S-2 Trackers and Sea King helos.
a trainer set, which includes T-2 Buckeyes, T-28 Trojans, some S-2 Trackers, some A-4 Skyhawks, F-9 Cougars, and F-4 Phantoms.
an attack set, including some S-2 Trackers, four A-4 Skyhawks and six F-8 Crusaders.
several different spacecraft recovery sets for Apollo & Gemini, which typically include some S-2 Trackers, SH-3 Sea King helos, and E-1 Tracers.
It will be an ambitious project to say the least. Attached is a photo of how she looked during your father-in-law's tour.
