USS LST-480 was an LST-1-class tank landing ship built for the United States Navy used in the Asiatic-Pacific Theater during World War II.

LST-480 was laid down on 31 August 1942, under Maritime Commission (MARCOM) contract, MC hull 1000, by Kaiser Shipyards, Yard No. 4, Richmond, California; launched on 29 October 1942; and commissioned on 3 May 1943.^[1][3][2]

During World War II, LST-480 was assigned to the Asiatic-Pacific theater and participated in the following operations:

• Gilbert Islands operation: Capture and occupation of Gilbert Islands, 13 November to 8 December 1943.
• Marshall Islands operation: Occupation of Kwajalein and Majuro Atolls, 29 January to 8 February 1944.

On 21 May 1944, LST-480 and at least 28 to 33 other LSTs were gathered near Waipio peninsula, in Pearl Harbor's West Loch, loading ammunition and supplies in preparation for the invasion of Saipan.^[4][5]

At 15:08, an explosion onboard LST-353, which may have originated near LCT-963, caused a chain reaction that would eventually sink LST-480, LST-353, and four other LSTs. At least two other LSTs were severely damaged and 163 sailors were killed with another 396 wounded.^[4][5]

While the other ships were removed and sunk at sea,^[5] the wreck of LST-480 can still be seen in the West Loch.^[6] 21°21′26″N 157°59′50″W / 21.35725°N 157.9972°W / 21.35725; -157.9972

LST-480 earned two battle stars for World War II service.^[3]
