The USS Osprey (AMS-28/YMS-422) was a YMS-1-class minesweeper of the YMS-135 subclass, constructed for the United States Navy during World War II. Built at Astoria Marine Construction in Oregon, she was laid down on October 9, 1943, launched on June 1, 1944, and commissioned on September 27, 1944. The vessel featured a wooden hull typical of minesweepers of her class, designed to reduce magnetic signatures and facilitate effective mine clearance. Initially, YMS-422 operated along the California coast, conducting patrols and minesweeping training. In early January 1945, she reported for duty with the Hawaiian Sea Frontier. Her activity primarily involved patrols and minesweeping operations, notably in the western Pacific. She played a significant role in clearing minefields around the Japanese home islands, including Nagoya in October 1945 and Kobe in December. Her operational service extended into the post-war period, demonstrating the ongoing need for minesweeping vessels even after World War II concluded. Renamed USS Osprey and redesignated AMS-28 on February 17, 1947, she actively participated in the Korean War. She conducted pre-assault minesweeping at Pohang in July 1950 to support the 1st Cavalry Division's landing operations and prepared firing bases for the USS Missouri at Inchon in September. During her service in Wonsan Bay, North Korea, she endured enemy fire, receiving three shell hits in October 1950, which required her to retreat briefly to Japan. Despite these dangers, her aggressive minesweeping and shore bombardment efforts were instrumental in clearing the way for major amphibious operations, earning her crew multiple medals and promotions. Redesignated MSC(O) in February 1955, Osprey was loaned to the Japanese Maritime Self Defense Force in March 1955, serving as Yakushima (YTE-10) until 1969. She was ultimately struck from the Navy Directory on June 15, 1969. Throughout her service, USS Osprey earned two battle stars for post-World War II operations and ten for her distinguished role in the Korean War, marking her as a vessel of notable maritime significance in both mine countermeasures and Allied naval operations.
