USS St. Joseph's River (LSM(R)-527) was laid down on 19 May 1945 by the Brown Shipbuilding Co., Inc., in Houston, Texas; she was launched on 16 June 1945 and commissioned on 24 August 1945.

Active for less than three months, LSM(R)-527 joined the 16th (Inactive) Fleet in November 1945; decommissioned on 28 March 1946, she remained berthed for the next four years at Green Cove Springs, Florida.

In the fall, she underwent overhaul at Mare Island Navy Yard; and with the winter of 1951-52, she resumed operations off southern California.

From 3 to 15 July and again from 16 August to 3 September, she helped to defend the islands held by United Nations forces, particularly Cho-Do and Sok-To in the approaches to the Taedong estuary.

Steaming via Midway Atoll and Pearl Harbor, LSM(R)-527 arrived in San Diego on 23 March and remained on the west coast until 10 February 1954.

The USS St. Joseph's River remained berthed at San Diego until activated in the summer of 1960, when she was transferred to the Republic of Korea Navy and commissioned as ROKS Si Hung (LFR-311).
