ASROC launcher replaced with a Tartar SAM launcher..
The Mk11 launcher on ships were later incorporated to fire RIM-66 Standard SAMS.
SAM launchers go either fore or aft for field of fire issues. Make sure there are no obstructions to that field of fire. Same with their associated directors and radars.
There was design work done on operating Tracker-Trader-Tracers (and presumably A-4s for strike and air defense) off of a Commencement Bay that had an angled deck refit).
Huh, that's interesting. Keep in mind though that Commencement Bay CVEs were fast for CVEs but still slow compared to fleet carriers - I don't know if they would've been fast enough to launch A-4s even with cats.
