USS Dauntless (SP-1002)

USS Dauntless (SP-1002) was a United States Navy patrol vessel in commission from 1917 to 1919.

Dauntless was built as a private motorboat of the same name around 1917 by W. Frank Harrison at Essex, Connecticut. On 11 September 1917, the U.S. Navy – whose inspectors had described Dauntless as a "new well built vessel ... suitable for gov't use as scout patrol in conn. with aeroplane work" – leased her from her owner, R. T. H. Barnes of Roxidge Avon, Connecticut, for use as a section patrol boat during World War I. She was commissioned as USS Dauntless (SP-1002) on 1 October 1917.

Assigned to the 2nd Naval District in southern New England, Dauntless served on patrol duties for the rest of World War I and into the early months of 1919.

The Navy returned Dauntless to Barnes on 17 May 1919.
