The USS Wissahickon (SP-852), also known as USS SP-852, was a United States Navy patrol vessel in service from 1917 to 1918, originally built as a private steam yacht. Laid down in 1899 by George Lawley & Son in Neponset, Massachusetts, the vessel was initially named Valda. Her construction featured a composite hull, combining an iron frame with wood planking, a common design at the turn of the century. She was completed in 1900 and later renamed Wissahickon in late 1901 or early 1902. At the time of her acquisition by the U.S. Navy, she was owned by Mrs. Charles W. Henry of Philadelphia. The vessel's transition to military service occurred during World War I, with the Navy acquiring her sometime between April and July 1917. Exact details of her commissioning remain uncertain, with sources indicating she was either commissioned as USS SP-852 or as USS Wissahickon (SP-852), with a possible name change in 1918. Her role was primarily coastal patrol, as she was considered too light for distant European waters. Assigned to the 1st Naval District in northern New England, she was initially based at Rockland, Maine, conducting patrols in its vicinity. During the winter of 1917-1918, her crew suffered from illnesses, leading to quarantine measures before she resumed patrol operations. In mid-summer 1918, Wissahickon was reassigned to Boston, where she operated from East Boston until the end of World War I and into early 1919. Her name was officially changed to USS Wissahickon (SP-852) sometime between September and November 1918. In January 1919, she moved to Camden, Maine, and was decommissioned on 12 February 1919. Shortly thereafter, she was stricken from the Navy List and returned to her former owner, Mrs. Henry, on 15 February 1919. This vessel exemplifies the adaptation of private yachts for wartime patrol duties, with her composite construction reflecting the maritime design practices of her era. Her service, though brief, contributed to coastal defense efforts during World War I, highlighting the Navy's reliance on civilian vessels for patrol and security roles during the conflict.
