The ship was transferred to the Chilean Navy as part of the Security Assistance Program on 30 September at San Diego. The LST was renamed "Valdivia" (LST-93) for a battle during the Chilean War of Independence. The ship arrived at its new Chilean homeport, Valparaíso, on 1 December 1995. In Chilean service, the LST operated with the Amphibious and Naval Transport Command (), performing operations from Arica to Puerto Williams. In mid-1997, "Valdivia" was damaged after going aground but repaired. During 2010, "Valdivia" was heavily involved in relief efforts following the series of earthquakes affecting Chile throughout 2010. The intense workload caused structural and component fatigue to the already old vessel, and an inspection in August 2010 concluded that repairing the ship would be uneconomical. "Valdivia" was decommissioned on 14 January 2011. The Chilean Navy planned to replace the LST with two landing platform dock type vessels.
