LST-504 was laid down on 21 July 1943 at Jeffersonville, Indiana by the Jeffersonville Boat & Machine Company; launched on 19 October 1943; sponsored by Mrs. W. J. Griffin; and commissioned on 18 December 1943. During World War II, LST-504 was assigned to the European Theater and participated in the Invasion of Normandy.
D-Day
As part of Operation Overlord, LST-504 departed Weymouth, England, on 4 June 1944. However, she turned back due to bad weather and would later re-embark on the night of 5 June. LST-504 reached Omaha beach the next morning, and dropped anchor about a half mile off shore to avoid floating mines.[1] In subsequent round trips made over the course of 30 days, the ship did land directly on the beach. On one such trip, the ship carried members of the 38th Cavalry Reconnaissance Squadron (Mechanized).[2]
Later Service
Following her service in Operation Overlord, LST-504 was directed towards Sicily to prepare for the invasion of Southern France. En Route, the convoy that LST-504 now led spotted a German ship. Orders were given for the convoy to turn, however one ship misinterpreted the order and turned the wrong way. A collision with that ship damaged the bow door of LST-504. The 504 was diverted to Bizerte, Tunisia for repairs.[3] Once the repairs were completed, the 504 embarked for her original destination of Italy. For the months of August and September, 1944, LST-504 carried troops between Italy and Southern France. She was then assigned to the Asiatic-Pacific Theater and took part in the assault and occupation of OkinawaGunto in April and June, 1945. Following the War, LST-504 performed occupation duty in the Far East until mid-January, 1946.She was decommissioned on 15 January 1946 in Tokyo Bay. The decommissioning ceremony took place on the main deck of the 504 at 5 minutes after 4 o'clock (1605 hours). At that time 19 officers and 30 enlisted men of the Japanese navy came aboard and the 504 was given to the Japanese. .
LST-504 earned three battle stars for World War II service.
