USS President Polk

Shortly after delivery in 1941 the SS President Polk began operating under government charter to supply and reinforce Pacific bases. The ship was then acquired by the War Shipping Administration (WSA) on 5 December 1941 with American President Lines operating the ship as WSA's agent.[3][4]

In a particularly critical delivery the ship was diverted from a planned shipment to Hawaii and departed San Francisco on 19 December 1941 along with a tanker and two freighters with arrival in Brisbane, Australia on 12 January 1942. There she delivered 55 P-40E and 4 C-53 aircraft including 55 pilots, 20 million .30 caliber, 447,000 .50 caliber, 30,000 three-inch AA and 5,000 75 mm rounds of ammunition along with five carloads of torpedoes, over 615,000 pounds of rations and 178 officers and men in addition to the pilots.[5][6] From Brisbane Polk, making a stop at Townsville, sailed to Soerabaja arriving on 30 January with ammunition, bombs, airplanes, and rations for forces in Java. Of eight vessels planned for relief of Java, and indirectly the Philippines, only Polk and the chartered Dutch vessel Bloemfontein, one of the Pensacola convoy vessels, arrived before that island fell on 9 March.[7]

Polk transported elements of the 7th Naval Construction Battalion composed of 7 officers and 433 enlisted men departing American Samoa 6 August 1942 arriving Espiritu Santo, New Hebrides on 11 August. The other element, 15 officers and 465 enlisted men, were embarked aboard USS Wharton.[8]

After acquisition 6 September 1943 and conversion by the Navy the ship was assigned to the Naval Transportation Service. USS President Polk loaded construction battalion men and cargo at Port Hueneme, California and sailed 12 October 1943 for Pearl Harbor.[3][2]

On 16 November 1943 she got underway for the invasion of Tarawa, Gilbert Islands, where she unloaded her troops and cargo and then stood by as casualty receiving ship. Returning to Pearl Harbor 11 December, she weighed anchor again 22 January 1944 to carry troops to Kwajalein in the Marshall Islands. Again used as an emergency hospital ship, she carried casualties to San Francisco, 24 February, then got underway with troops and cargo for New Caledonia, in the Solomon Islands, and the Admiralty Islands.[2]

In July she carried reinforcements to Guam and again sailed east with wounded personnel, arriving at Pearl Harbor 11 August and continuing on to California where she took on personnel and cargo for New Guinea. Arriving at Milne Bay 6 November, she loaded passengers and cargo, then proceeded to Bougainville Island to prepare for the invasion of Luzon. Disembarking troops on the Lingayen assault beaches, 11 January 1945, she ferried reinforcements from Leyte, then sailed to Ulithi to take on Marines at Iwo Jima and return them to Hawaii. Thence she steamed to San Francisco, took on fresh troops, and headed west to Okinawa 24 July.[2]

V-J Day found her in Apra Harbor, Guam, whence she returned to San Francisco. Next, she transported troops from Seattle to Tinian, reported for Operation Magic Carpet 13 October, and completed runs from Espiritu Santo and Manila to San Francisco before the end of the year. USS President Polk, with six battle stars for her World War II service, decommissioned and was transferred to the War Shipping Administration for return to her owner 26 January 1946, President Polk was struck from the Navy List 25 February 1946.[2]
