1943

Langley was launched on 22 May 1943 and commissioned on 31 August 1943, Captain W.M. Dillon in command. After shakedown in the Caribbean Sea, Langley departed Philadelphia on 6 December 1943 for Pearl Harbor, where she participated in training operations.

1944

On 19 January 1944, she sailed with Task Force 58 (TF 58) for the attack on the Marshall Islands. From 29 January to 6 February, Langley's Carrier Air Group 32 (CVG-32) conducted raids on Wotje and Taroa Island to support the landings at Kwajalein, and from 10 through 28 February at Eniwetok. After a brief respite at Espiritu Santo, New Hebrides, Langley's aircraft hit Japanese positions on Palau, Yap, and Woleai, Caroline Islands, from 30 March to 1 April. She next proceeded to New Guinea to take part in the capture of Hollandia on 25 April. A mere 4 days later, the carrier engaged in the 2‑day strike against the Japanese bastion Truk. During the raid, Langley and her aircraft accounted for some 35 enemy planes destroyed or damaged, while losing only one aircraft herself.

Langley next departed Majuro on 7 June 1944 for the Mariana and Palau Islands campaign. On 11 June, TF 58 launched a strike of 208 fighters and eight torpedo bombers against enemy bases and airfields on Saipan and Tinian. From 11 June to 8 August, Langley operated with TF 58 and also took part in the Battle of the Philippine Sea, 19 to 20 June 1944.

The carrier departed Eniwetok on 29 August and sortied with TF 38, under the command of Adm. William F. Halsey for air assaults on Peleliu and airfields in the Philippines as the preliminary steps in the invasion of the Palaus from 15 to 20 September 1944. During October, she operated off Formosa and the Pescadores Islands. Later in the month, TF 38 supported the landings on Leyte. The Japanese efforts to stop the U.S. advance included the counterattack by most available major fleet units ("Operation Sho-Go"). On 24 October, Langley's planes took part in the Battle of the Sibuyan Sea. Aircraft of TF 38 attacked the Japanese Center Force, as it steamed toward the San Bernardino Strait and the American beachhead at Tacloban. The Japanese units temporarily retired. The following day, upon word of Japanese aircraft carriers north of Leyte, TF 38 raced to intercept. In the ensuing Battle off Cape Engaño, the Japanese lost four carriers, two battleships, four heavy cruisers, one light cruiser, and five destroyers. Langley's aircraft assisted in the destruction of the carriers Zuihō and Zuikaku, the latter being the only remaining carrier of the six that had participated in the Pearl Harbor attack.

During November 1944, Langley supported the Philippine landings and strikes the Manila Bay area. Aircraft of Langley's CVG-44 attacked Japanese reinforcement convoys, and airfields on Luzon and in the Cape Engaño area. On 1 December, the carrier withdrew to Ulithi for reprovisioning.

1945

During January 1945, Langley participated in the South China Sea raid supporting Invasion of Lingayen Gulf. Raids were made against Formosa, French Indochina, and the China coast from 30 December 1944 to 25 January 1945. Langley's task group was attacked by two dive bombers on 21 January. One 50 kg (110 lb) bomb struck the center of Langley's flight deck forward and penetrated to the gallery deck to explode among the officers' staterooms just aft of the forecastle. The fire was quickly extinguished, and the flight deck repaired to continue flight operations. The second bomber inflicted greater damage on USS Ticonderoga.^[1]

Langley next joined in the sweeps against Tokyo and Nansei Shoto in support of the landings on Iwo Jima between 10 February and 18 March 1945. She next raided airfields on the Japanese homeland, and arrived off Okinawa on 23 March. Until 11 May, the ship operated either off Okinawa or took part in strikes on Kyushu, Japan, in an effort to destroy kamikaze bases in southern Japan which were launching desperate and deadly suicide attacks.

After touching Ulithi and Pearl Harbor, she steamed to San Francisco, arriving on 3 June for repairs and modernization at the Hunters Point Naval Shipyard. She departed 1 August and reached Pearl Harbor on 8 August 1945. While there, word arrived that hostilities had ended. She completed two "Magic Carpet" voyages to the Pacific, transporting soldiers back to the United States, and got underway on 1 October for Philadelphia.

1946

She departed from that port 15 November for the first of two trips to Europe transporting U.S. Army troops returning home from that theater. She returned to Philadelphia on 6 January 1946 and was assigned to the Atlantic Reserve Fleet, Philadelphia Group, on 31 May 1946. Langley was decommissioned on 11 February 1947.
