In June 1951, "Randolph" commenced her SCB-27A modernization program at Norfolk Naval Shipyard. To handle the new generation of carrier aircraft, the flight deck structure was reinforced. Stronger elevators, more powerful hydraulic catapults, and new arresting gear were installed. The island structure was rebuilt, the anti-aircraft turrets were removed, and blisters were added to the hull. Reclassified CVA-15 on 1 October 1952, "Randolph" recommissioned on 1 July 1953. After shakedown off Guantanamo Bay with Carrier Air Group 10, she took on Carrier Air Group 14, departed Norfolk for the Mediterranean, and joined the 6th Fleet on 3 February 1954. Deployed to the Mediterranean for 6 months of Fleet and NATO exercises in 1954–1955, "Randolph" entered the Norfolk Naval Shipyard on 18 June 1955 for installation of an angled flight deck and other SCB-125 modernizations.
