The USS Ostrich (MSC(O)-29/AMS-29/YMS-430) was a YMS-1-class minesweeper built for the United States Navy during World War II, belonging to the YMS-135 subclass. Constructed by the Tacoma Boatbuilding Company in Tacoma, Washington, she was laid down on November 10, 1943, launched on March 23, 1944, and commissioned on October 10, 1944. The vessel’s design was typical of minesweepers of her class, optimized for clearing naval mines to ensure safe passage for Allied ships. Following her commissioning, the USS Ostrich undertook shakedown training before sailing to Pearl Harbor on December 19, 1944, as part of a convoy screening operation. She arrived at Pearl Harbor on December 28 and soon thereafter escorted a convoy to Eniwetok, departing on January 4, 1945. She continued her operations in the Pacific, arriving at Ulithi on February 5, where she remained until June 14. She then proceeded to Okinawa to participate in minesweeping activities, vital for maintaining safe passage during the final stages of the Pacific campaign. After Okinawa, YMS-430 moved to Japanese waters, arriving at Wakayama on September 8, 1945. She operated in Japanese harbors and waters, clearing mines until February 16, 1946, when she departed for the United States. She arrived in San Pedro, California, on April 2, and later moved to Charleston, South Carolina, arriving on July 3. Due to personnel shortages, she was placed in reduced commission but was reactivated on December 10, 1946, for training along the Atlantic coast, extending her operational range from Labrador to Florida. On February 18, 1947, the vessel was named Ostrich and redesignated AMS-29. She continued minesweeping exercises and occasionally performed hydrographic work until her decommissioning at Green Cove Springs, Florida, in January 1958. Struck from the Naval Vessel Register in November 1959, USS Ostrich was sold for scrap in early 1960. Her service exemplifies the vital role of minesweepers in ensuring safe naval and maritime operations during and after World War II.
