The USS Tern (SP-871) was a United States Navy patrol vessel built as a private motorboat in 1907 by Murray and Tregurtha in South Boston, Massachusetts. Originally owned by E. F. Nail of Atlantic City, New Jersey, the vessel was acquired by the U.S. Navy on 28 May 1917 for wartime service during World War I. Upon acquisition, she was commissioned immediately as USS Tern (SP-871). The vessel served primarily within the 4th Naval District, conducting patrol duties along the U.S. East Coast. As a patrol craft, her role was to monitor and secure maritime approaches during a period of heightened naval activity, contributing to the broader wartime effort to safeguard the coastline and maritime traffic from potential threats such as enemy submarines and surface raiders. In 1918, to avoid confusion with a new minesweeper also named USS Tern (Minesweeper No. 31), the vessel was renamed USS SP-871. Her service with the Navy was relatively brief, spanning from her commissioning in May 1917 until her return to her owner on 21 November 1918, shortly after the end of World War I. The USS Tern (SP-871) exemplifies the common practice of the U.S. Navy acquiring private vessels for auxiliary and patrol roles during wartime, quickly converting civilian craft into military assets to bolster coastal defenses. Her service history reflects the vital contribution of small patrol vessels in maintaining maritime security during a period of global conflict.
