The USS Miramar (SP-672), later designated USS SP-672, was a United States Navy patrol vessel active during World War I. Originally built in 1907 as a private motorboat named Lillian II, she was constructed in Long Island City, New York. The vessel’s design and specifications are not detailed in the provided source, but as a private motorboat converted for naval service, she would have been relatively small and maneuverable, suitable for patrol duties along the coast. In August 1917, with the United States actively involved in World War I, the Navy acquired the vessel from her owner for military use. She was commissioned as USS Miramar (SP-672) on August 31, 1917, and assigned to the 8th Naval District. Her primary role was to conduct patrols along the U.S. coastline, a typical duty for section patrol boats during the war, aimed at safeguarding maritime interests and preventing enemy activity. During 1918, her name was officially changed to USS SP-672, reflecting her identification as a section patrol craft. The vessel’s service was relatively brief; after approximately a year of patrol operations, she was returned to her owner on December 30, 1918, shortly after the end of World War I. Her service record indicates that she played a part in the Navy’s coastal defense efforts during the wartime period. The USS Miramar (SP-672)’s significance lies in her role as part of the United States’ broader naval mobilization during World War I, exemplifying the use of private vessels converted for wartime patrol duties. The vessel’s relatively modest scale and short service life highlight the Navy’s reliance on a diverse fleet of private craft to augment its wartime patrol capabilities.
