Oglethorpe is a county in Georgia named in honor of James Oglethorpe, founder of the state.

Oglethorpe (AKA-100) was laid down 26 December 1944 by the Federal Shipbuilding and Drydoek Co., Kearny, New Jersey, under contract for the Maritime Commission. Transferred to the Navy while still on the ways, she was launched 15 April 1945, sponsored by Mra Ellsworth Buck, wife of the New York Congressman, and commissioned at the Navy Yard, Brooklyn, N.Y., 6 June 1945, Captain James Campbell, USNR, in command.

Following shakedown in Cheseapeake Bay, she served as a training vessel at Little Creek, Va. and Newport, R.I. On 1 August 1945, the ship sailed for Pearl Harbor via the Panama Canal. Receiving news of Japan's surrender enroute, the ship continued on to the western Pacifie. After carrying general cargo between Pearl Harbor, Kwajalein, Guadalcanal, and Noumea, in December 1945, she returned to the United States and was assigned to NTS and, later, MSTS. Remaining a commissioned ship, she carried cargo in the Western Pacifie until 25 June 1950.

When the Communists invaded the Republic of Korea, she joined amphibious forces in Yokosuka, Japan 9 July. Quickly converted in Japan for wartime operation, Oglethorpe carried equipment for the 1st Calvalry Division to Po Hung Dong, Korea, where the troops landed 18 July. Returning to San Diego in August, she embarked men and equipment of the 1st Marine Division. Arriving off Inehon, Korea 15 September, for six days she supported the amphibious assault which briefly reversed the course of the war, sending Communist troops scurrying baek to North Korea.

After a round trip to Japan, she reloaded equipment of the 1st Marine Division for the assault at Wonsan. Arriving off Wonsan 25 Oetober she supported the operation until the 30th and then returned to the West Coast.

Transferred to the Atlantie Fleet in January 1951, Oglethorpe participated in amphibious training along the East Coast, in the Carribean, and the Mediterranean. In October 1955, she made two trips to aid flood stricken Tampico, Mexico. Crewmen in six LCMs distributed food, clothing, and medicine to flood victims far up the swollen and treacherous Panueo River.

Resuming her pattern of operations alternating East Coast training and Mediterreanean deployments, the ship was part of the fleet that brought the Marines to Lebanon in July 1958. In October 1962, Oglethorpe stood ready off Cuba when President Kennedy demanded the removal of Soviet missiles. The The prompt and firm employment of U.S. Naval power forced the rapid withdrawal of the offensive missiles and maintained peace in the Western Hemisphere. Once again in the Mediterranean, the ship joined the ready forces as hostilities heightened between Greek and Turkish factions on Cyprus in early 1964.

Returning from the Mediterranean in August 1966, the ship entered Boston Naval Shipyard in early January 1967. Following overhaul she continued her pattern of East Coast training and Mediterranean deployments until struck from the Navy List 1 November 1968.

Oglethorpe received two battle stars for Korean service.
