USS Calvert (APA-32) was a Crescent City-class attack transport that served with the United States Navy during World War II and the Korean War. In addition to her ten battle stars, Calvert was awarded a Navy Unit Commendation.

Calvert was launched 22 May 1942 as Delorleans by Bethlehem Sparrows Point Shipyard under a Maritime Commission contract. Acquired by the Navy 30 September 1942, she became the second Navy ship named after Calvert County, Maryland, designated transport AP-65. She was commissioned the next day, Captain D. W. Loomis in command. She was reclassified as attack transport APA-32, on 1 February 1943. 

Mediterranean Theatre

Calvert began the consistently superior service which was to win her a Navy Unit Commendation when she sailed from Norfolk, Virginia on 25 October 1942 for the invasion of North Africa. She landed her troops at Safi, French Morocco, on 8 November, and six days later sailed for Norfolk to train troops in Chesapeake Bay for other invasions. On 8 June 1943 she departed for the Mediterranean and her second major assault landing, the invasion of Sicily. She put her troops ashore at Scoglitti, Sicily, on 12 July.

Pacific Theater

By 3 August 1943, Calvert was back at Norfolk, a veteran of assault landings in the Atlantic, and now Pacific-bound for stepping stone invasions to the Japanese homeland. She arrived at Pearl Harbor on 26 September to train and land troops of the 27th Infantry Division on Makin, Gilbert Islands, 20 November. Her busy schedule took the transport back to the west coast the following month to train troops for forthcoming amphibious assaults, and in January 1944 she was underway for theMarshalls where on 1 February her troops stormed ashore on Kwajalein for another successful invasion.

Calvert's next operation was in the Marianas, where she conducted diversionary landings off Tanapag Harbor at Saipan (15–24 June) and Tinian (24 July), an effort which added to the success of the main assault on Saipan. She returned to Pearl Harbor in August carrying 420 Japanese and Korean prisoners of war, and the following month was again westward bound to take part in theinvasion of the Philippines.

On 20 October 1944 Calvert was off Leyte dispatching her troops for the initial landings. She made a quick turn around and was back on 18 November to pour more men and equipment fromNew Guinea into the Philippines to ensure the Allied advance. At Cape Gloucester she embarked troops for another assault on the Philippines (9 January 1945) at Lingayen Gulf to begin the capture of Luzon. The following month, with troops embarked at Biak, Calvert successfully landed her assault waves at Mindoro on 9 February.

The veteran Calvert was now ordered to the west coast for overhaul and conversion to an amphibious flagship, arriving Bremerton on 26 March. Calvert completed her conversion as the war ended in the Pacific, and on 24 August 1945 cleared for the Philippines to lift troops to Hiro Wan for the occupation of Japan. Magic Carpet duty, returning troops home to the west coast, was her assignment between 7 November 1945 and 31 May 1946.

Calvert arrived at Norfolk where she was placed out of commission in reserve 26 February 1947.

Korean War

With the outbreak of the Korea War in the summer of 1950, Calvert was recalled to active service and recommissioned 18 October 1950. During her two tours ( actually, the Calvert made three tours ) in theFar East she trained troops in Japan and Korea, redeployed Korean troops, and transported troops to and from Korea from the west coast.
