After returning to Ulithi, the fast carrier task force began a series of strikes on targets on Formosa, the coast of French Indochina, occupied China, and the Ryuku Islands in January 1945. "North Carolina" remained in TG 38.3 for the operation, and her carrier group struck northern Formosa on 3–4 January, but poor weather hampered flight operations. Further attacks struck targets on Luzon on 6 and 7 January to destroy reserves of kamikazes there. On 10 January, the carrier groups entered the South China Sea to strike targets in French Indochina on the assumption that significant Japanese naval forces were present, but only merchant ships and a number of minor warships were caught and sunk there. During these raids, other elements of the Allied fleet invaded Lingayen Gulf on Luzon.
