Service history

World War II, 1945

Following shakedown in the Gulf of Mexico, LST-904 loaded cargo at New Orleans and departed on 1 March for the Pacific. She reached Pearl Harbor on 2 April, thence sailed in convoy on 16 April via Eniwetok and Guam to Saipan where she arrived on 12 May. There she embarked Army Signal Corps troops and equipment, and on 12 June steamed to the Ryukyu Islands. Reaching Okinawa the 18th, from 23 to 28 June she beached at Ie Shima before returning to Hagushi to complete cargo operations. In addition she embarked marines for transfer to the Marianas. Departing on 10 July, she touched Guam the 16th and arrived Saipan two days later for availability. Between 30 July and 2 August, LST-904 steamed to Iwo Jima where she loaded a cargo of steel pilings.

Post-war activities, 1945–1946

After returning to Saipan the 23rd, she headed for Okinawa on 29 August and began discharging cargo on 4 September. Unloading completed, she embarked men of the Fifth Air Force and carried them to Yokohama, Japan between 29 September and 4 October. Between 12 October and 8 November she sailed to the Philippine Islands and transported additional occupation troops to Japan. She operated along the Japanese coast from Aomori to Yokohama until departing for the Marianas on 7 December. She reached Saipan on 13 December, thence steamed via Guam to Pearl Harbor where she arrived on 21 January 1946.

After loading LCT-1458 on her main deck, LST-904 departed for San Francisco on 29 January. She arrived in early February and operated along the west coast until 10 July when she was placed in commission, in reserve with the 19th Fleet.

Decommissioning and disposal

LST-904 decommissioned on 15 November 1946 and joined the Pacific Reserve Fleet in the Columbia River. She was named USS Lyon County (LST-904) on 1 July 1955. On 20 October 1958 the Secretary of the Navy recommended that she be used as a target to destruction. Her name was struck from the Naval Vessel Register on 1 November. Towed to Bremerton, Washington on 31 December, her hulk was sunk in 1,280 fathoms of water off the coast of Washington on 13 May 1959 by torpedoes fired from the Capitaine (SS-336).


LST-904 received one battle star for World War II service.
