"Does anyone know the criteria that decided which carrier received the SCB27a, 27c and 125 upgrades? Why did the ANTIETAM only get the angle deck; was that the test ship? It couldn't be condition, because the INTREPID sustained major battle damage in WWII and it still received all three upgrades. CV-39, 40, 45 and 47 weren't considered and they were 2-3 years newer."
Any assistance is greatly appreciated.
Educated guess - and that's all this is, so somebody call me out if I'm wrong - is that CV-40, 45 and 47 (among others), being newer ships, had remained active postwar and were still needed on the front line at the time, especially given the needs of Korea and other early '50s hotspots. Older ships that had been laid up and weren't in use at the time were available for the extended yard periods needed for modernization.
Antietam was indeed the test ship for the angle deck (and it was a pretty basic conversion for test purposes, though she retained the modification).
The two things I look at most carefully are funding and scheduling - when a ship was scheduled into a modernization program, the funding that was available, etc. I'm away from my books right now, but IIRC Friedman's
U.S. Aircraft Carriers: An Illustrated Design History went into the rationale a little bit. I remember funding, and scheduling, had a lot to do with why
Lake Champlain never received a planned SCB-125 modernization. And even if the funding had been there, by the time you would have been able to get the likes of CV-21, CV-40, -45 and -47 into the modernization pipeline, bigger carriers were starting to haul more of the frontline load, the sun was starting to set on what the smaller carriers could do, and other missions called (i.e., the three LPH conversions; the -27A units moving from the CVA mission to the supporting CVS mission, and so forth).
The two ships with the most intriguing stories are
Bunker Hill and
Franklin, which although extensively repaired after the war were never modernized. I've never been fully able to nail down why, unless their damage had been beyond what could be totally repaired.
