Harry Lee, APA-10, was the only ship of her class. New York Shipbuilding built her at Camden in 1931 as the American Export Lines passenger liner Exochorda, one of the four Aces on the Mediterranean run. The Navy acquired her on 30 October 1940 and had Tietjen and Lang convert her at Hoboken. She was commissioned as the transport Harry Lee (AP-17) on 27 December 1940, Captain Robert P. Hinrichs in command, and was redesignated APA-10 on 1 February 1943.
She carried Marines to the Caribbean and troops to Iceland in 1941, then spent about eighteen months testing landing craft and boat control in the Caribbean. She landed her troops through heavy surf at Scoglitti, Sicily, on 10 July 1943 and withstood several air attacks. She then returned German prisoners to the United States and went to the Pacific. She launched her Marines at Tarawa on 20 November 1943.
At Kwajalein on 31 January 1944 she landed troops on two small islands of the atoll, which met little opposition, and she stayed until 5 February before leaving for Funafuti. She arrived at Aitape on 23 April for Hollandia, after the first assault. For Guam she was held in reserve, landed her troops at Agat on 21 July 1944, and stayed offshore loading and relanding troops until 25 July. After an overhaul she was at Lingayen Gulf on 9 January 1945, escaping the kamikaze and bomber attacks on the way, and her last amphibious operation was Iwo Jima, where she arrived on 22 February.
She was decommissioned at New York on 9 May 1946, laid up in the Hudson River Reserve Fleet on 12 September, and struck on 20 September 1946. NavSource lists her final disposition as destroyed by fire on 14 December 1960 in a three-ship collision in the Bosphorus. She earned seven battle stars.
