On 27 May 1945, the 5th Fleet was redesignated the 3rd Fleet when Admiral Halsey relieved Admiral Spruance. Three days later, "Springfield" anchored in San Pedro Bay at Leyte in the Philippines for maintenance and upkeep. One month later, she departed Leyte and joined TF 38 for further air strikes against the Japanese home islands. On 10 and 11 July, the carriers launched planes against Tokyo. On the 13th and 14th, their targets were northern Honshū and Hokkaidō. The task force conducted an anti-shipping sweep along the coast of Honshū on the night of 14/15 July, and then, two days later, returned to hit Tokyo and Yokohama again. The planes bombed battleships "Nagato" and "Haruna", on 18 July; then pounded Kobe and Kure on 24, 25, and 28 July. "Springfield" joined in a bombardment again on the night of 24/25 July; this time the targets were shore installations on southern Honshū. On 30 July, Tokyo once more suffered from the wrath of the flattops. Sweeping the coast of Honshū for enemy ships as they went, TF 38 returned to bomb northern Honshū and Hokkaido on 9 and 10 August. Three days later, the carriers sent their planes against Tokyo for the last raid of the war—on the 15th, hostilities in the Pacific ended. "Springfield" entered Sagami Wan with TF 35 and anchored there on 27 August. Three days later, she covered both the entry of TF 31 into Tokyo Bay and the occupation of the Yokosuka Naval Base; and then returned to her anchorage. On 3 September, the light cruiser entered Tokyo Bay itself. On 20 September, while she was still in Tokyo Bay, the 3rd Fleet became the 5th Fleet again upon the return of Admiral Spruance. "Springfield" remained in the Far East until early January 1946. During the intervening three months, she visited Sasebo and Yokosuka in Japan; Shanghai, Taku, Tsingtao, and Chinwangtao in China; and Jinsen, Korea. On 9 January 1946, she departed Tsingtao and headed east. She arrived in San Pedro, Calif., on 25 January en route to the Navy Yard at Mare Island. The light cruiser returned to San Pedro on the 15th. She operated along the West Coast until 1 November, when she headed back to the Western Pacific.
