USS Patrol No. 5

USS Patrol No. 5 (SP-29), often rendered as USS Patrol #5, was an armed motorboat that served in the United States Navy as a patrol vessel from 1917 to 1919.

Background
Patrol No. 5 was built as a private motorboat of the same name in 1916 by Britt Brothers at Lynn, Massachusetts. She was one of five motorboats built to the same design for private owners by Britt Brothers as part of the civilian Preparedness Movement program with an understanding that they would enter U.S. Navy service in time of war, the others being Patrol No. 1, which later became USS Patrol No. 1 (SP-45); Patrol No. 2, which later became USS Patrol No. 2 (SP-409); Patrol No. 3, which never entered U.S. Navy service; and Patrol No. 4, which later became USS Patrol No. 4 (SP-8).

The U.S. Navy purchased Patrol No. 5 from her owner, Roland C. Nickerson of East Brewster, Massachusetts, on 7 April 1917 and commissioned her for service during World War I as USS Patrol No. 5 (SP-29) on 13 April 1917. She operated in the 2nd Naval District, headquartered at Newport, Rhode Island, on patrol during the remainder of the United States' participation in World War I.

Patrol No. 5 was decommissioned postwar and sold to Reinhard Hall of Brooklyn, New York, on 23 April 1919.
