The USS Caspian (ID-1380) was a proposed United States Navy vessel that ultimately never entered naval service. Originally, she was a commercial tugboat named SS Caspian, constructed in 1912 by the shipbuilding company John Dialogue and Son, located in Camden, New Jersey. The vessel featured a steel hull, typical of early 20th-century tugboats, designed for durability and strength required for towing and harbor duties. In early March 1918, during World War I, the Commandant of the U.S. Navy’s 4th Naval District ordered that SS Caspian be taken over for naval service, reflecting the wartime expansion and need for auxiliary vessels. The Navy assigned her the hull classification ID-1380, indicating her intended role as a support vessel. The plan was to commission her as USS Caspian and incorporate her into the naval fleet to assist with wartime operations. However, despite the Navy’s designation and plans, the transfer of the vessel was never completed. The Navy did not take possession of SS Caspian, and she remained in civilian hands throughout the war. She continued to serve her original owner, P. F. Martin of Philadelphia, Pennsylvania, and retained her commercial function. As a result, the USS Caspian (ID-1380) is notable primarily as a vessel that was designated for Navy service but never actually served in the U.S. Navy fleet. This vessel’s history highlights the wartime practice of requisitioning commercial ships for auxiliary roles, many of which were ultimately returned to civilian service. The SS Caspian stands as an example of a ship prepared for potential military use but that, for reasons not specified, was never transferred or commissioned into naval service.
