Number 63 on the "island" (starboard air traffic, radio/radar apparatus, ship command structure) and bow flat-top deck refers to carrier designation CVA-63 (changed to CV-63 in 1970s).

This naval designation used since 1920s enabled multiple US ships to have same name but in different service eras. For example, Langley referred to US first carrier CV-1 in 1920 and WW2-era Independence-class CVL-27. Enterprise referred to WW2-era CV-6 and nuclear carrier CVN-65. Yorktown referred to CV-5 (sunk 1942 Battle of Midway) and her Essex-class replacement CV-10. Hornet referred to Yorktown-class CV-8 (sunk 1942 Battle of Coral Sea) and her Essex-class replacement CV-12. Princeton was CVL-23 (sunk 1944 Battle of Surigao Strait) and current CG-59 Guided Missile Cruiser. F-4 Phantom II - en.wikipedia.org/wiki/F-4

A-3 Skywarrior bomber was US Navy version of US Air Force B-66 bomber. Original concept was to give carrier-based squadrons strategic bombing capabilities, but advancements in intercontinental missiles and air defense technologies by mid-1960s negated this practicality. Thus, A-3 bombers were converted to carrier-based EA-3 airborne electronic counter-measures, KA-3 airborne refueling tankers, RA-3 long-range recon planes.
