Below here, for reference, is a short History for the U.S. Enterprise CV-6:
U.S.S. Enterprise, a 19,800 ton Yorktown class aircraft carrier, was built at Newport News, Virginia. Commissioned in May 1938, she made a shakedown cruise to South America, then operated in the Caribbean. In April 1939, Enterprise was ordered to the Pacific, where she was to play an unparalleled role in the great sea war that began with Japan’s 7 December 1941 attack on Pearl Harbor.
At the time of that raid, Enterprise was at sea. On 10 December, her planes sank a Japanese submarine, the first of many enemy ships that would fall victim to her air group. Later in December, she participated in the abortive Wake Island relief expedition. In February 1942, after escorting convoys to the South Pacific, Enterprise attacked Japanese positions in the Marshalls. During the following three months, she hit Wake and Marcus islands, covered the Doolittle raid on Japan and was en route to the South Pacific when the Battle of the Coral Sea took place in early May.
In June 1942, Enterprise played a vital role in the Battle of Midway, in which her planes sank or helped sink three Japanese aircraft carriers, and a cruiser. She was next involved in the Guadalcanal Campaign, including the landings there in early August, the Battle of the Eastern Solomons later in that month and the Battle of the Santa Cruz Islands in October. Badly hit by Japanese bombs in August and October, Enterprise was the only available fleet carrier in the area in November, and despite her damaged condition, launched her air group against enemy ships during the climactic Naval Battle of Guadalcanal. Remaining in the Solomons area into the Spring of 1943, she received the Presidential Unit Citation for her exploits there.
In late 1943 and early 1944 Enterprise participated in the Gilberts and Marshalls invasions and in attacks on Japanese bases in the Central and Southern Pacific. In June and July, she took part in the Marianas operation and the Battle of the Philippine Sea. From August to December, her planes joined in more raids and again engaged enemy ships during the Battle of Leyte Gulf in late October. At the end of 1944 Enterprise received a special night operations air group, with which she took part in the Luzon campaign, strikes in the South China Sea, the Iwo Jima invasion, raids on the Japanese home islands and the Okinawa campaign. She was repaired locally for bomb damage received on 13 March 1945 and Kamikaze damage on 11 April, but had to the return to the U.S. after being badly hit by another Kamikaze on 14 May.
Enterprise’s repairs were finished in September 1945, after the Japanese surrender. She helped return servicemen from the war zones and was present for the Fleet Review off New York City in October 1945. Inactive after early 1946, Enterprise decommissioned in February 1947. While laid up, she was redesignated CVA-6 in October 1952 and CVS-6 in August 1953. After the failure of efforts to make her into a memorial, the U.S.S. Enterprise was sold for scrapping in July 1958.
