The USS Castine (IX-211), originally designated PC-452, was a distinctive experimental vessel built for the United States Navy during World War II. Constructed at the DeFoe Boat and Motor Works in Bay City, Michigan, she was laid down on March 14, 1940, as part of the Experimental Small Craft program initiated in May 1938. The ship was launched on August 23, 1941, and subsequently towed to the Philadelphia Navy Yard for outfitting with boilers. She was officially commissioned on May 1, 1944, initially serving as a submarine chaser. Designed as a 173-foot vessel, PC-452 was part of an experimental class known as "X-Boats," which included her sister ship PC-451. These ships differed in propulsion systems: PC-452 was fitted with a steam turbine, serving as a test bed for steam propulsion technology, while PC-451 employed a diesel-electric drive. Despite being listed as 165-footers, their actual length was 173 feet, reflecting their specialized design purpose. In March 1945, the vessel was reclassified as an Unclassified Miscellaneous Auxiliary and received the hull number IX-211, at which point she was renamed Castine after the town in Maine. Her role was primarily experimental, focusing on steam turbine propulsion, which was a significant aspect of naval engineering research at the time. Castine was decommissioned on October 3, 1945, shortly after the end of World War II, and was struck from the Naval Register. She was transferred to the Maritime Commission for disposal in January 1947. Her ultimate fate remains unknown. Notably, her executive officer, Lt. (j.g.) John W. Hazard, documented the steam propulsion experiments in an article for The New Yorker, which later inspired the 1951 film "You're in the Navy Now." The USS Castine holds maritime significance as a test vessel that contributed to the development of naval propulsion systems during the war era.
