Very likely. At the very least, electronics don't like moisture, and A/C mitigates that. The USN retrofitted the Essex and Midway classes with A/C during their SCB-125 and SCB-110/101.66 refits, respectively, and the Forrestals had A/C from the beginning.Looking at these photos with open hanger doors, one question came to my mind. Do these carrier hangers have air conditioning?
If not, these hangers will become furnaces in hong kong summer weather
