USS LST-919 was an LST-542-class tank landing ship in the United States Navy. Like many of her class, she was not named and is properly referred to by her hull designation.

LST-919 was laid down on 11 April 1944, at Hingham, Massachusetts, by the Bethlehem-Hingham Shipyard; launched on 17 May 1944; and commissioned on 31 May 1944.^[3][2]

During World War II, LST-919 was assigned to the Asiatic-Pacific theater and took part in the Leyte landings in October and November 1944, the Lingayen Gulf landings in January 1945, and the Mindanao Island landings in April 1945.^[3]

Following the war, LST-919 performed occupation duty in the Far East and saw service in China until early April 1946. She returned to the United States and was decommissioned on 5 August 1946, and struck from the Navy list on 25 September, that same year. On 10 January 1948, the ship was sold to Pablo N. Ferrari & Co. for operation.^[3] On 1 March 1948, she was resold to the government of Argentina.^[2][4]

In Argentine service, LST-919 was renamed Cabo San Isidro and redesignated BDT-6 (Buque Desembarco de Tanques), later Q46. She was retired in 1979.^[5] She still existed at the time of the Falklands War, but was not available for use.^{[citation needed]}

LST-919 earned three battle stars for World War II service.^[3]
