during Operation Tan No. 2. The initial damage assessment by the ship's captain and later confirmed by task force commander, Admiral Raymond Spruance, was that Randolphs damage was beyond the repair capabilities at Pearl Harbor and the ship would have to return to Navy facilities on the US west coast, effectively taking Randolph out of action for some five months, including the upcoming invasion of Okinawa. At this point, Randolphs catapult officer was able to convince the captain and Spruance that repairs could be completed at sea utilizing , a repair ship in the immediate vicinity. What ensued became the most extensive repair at sea ever performed by the US Navy. The captain's first act was to move number six (forward) arresting-gear catapult engine aft to replace the destroyed number one engine. This returned Randolph, very quickly, to an operational status. With Randolph able to launch and retrieve aircraft, and thus defend herself, repairs focused on the massive task, at the ship's stern, involving the replacement of structural steel components forming the hangar deck, aircraft elevator framework and flight deck support, all warped or destroyed by the fires ignited by the kamikaze hit. Some 29 tons of structural steel, including I-beams salvaged from a Japanese sugar mill on newly liberated Saipan, were utilized. An additional 7,500 board feet of lumber was required to repair Randolph’s flight deck. In the words of Cmdr. Charles Minter, assistant air officer on board Randolph, "That decision to remain in the forward area [for repairs] allowed us to complete the war in an operational status. I doubt anyone could estimate how long we would have been in the yard had we gone back to the States, and the loss of the Randolph at that particular time would have been crucial. Slingin' Sam (Lt. Cmdr. Samuel Humphreys) saved the day". Working twenty four hours a day at sea off Ulithi, Randolph’s repairs, initiated after the fires from the 11 March kamikaze attack were extinguished, were completed by 1 April, the launch date of the Okinawa invasion. Randolph joined Task Force 58 on 7 April. Combat air patrols (CAP) were flown daily until 14 April, when strikes were sent against Okinawa, Ie Shima, and Kakeroma Island. The following day, an air support mission of fighters, bombers, and torpedo planes hit Okinawa and a fighter sweep struck an airfield in southern Kyūshū. Under daily air attack from 17
