USS Fli-Hawk (SP-550) was a United States Navy patrol vessel in commission from 1917 to 1919.
Fli-Hawk was built as a private motorboat [3] or motor yacht [4] of the same name in 1912. In 1917, the U.S. Navy acquired her under a free lease from her owner for use as a section patrol vessel during World War I. She was commissioned as USS Fli-Hawk (SP-550) on 12 May 1917.
Assigned to the 5th Naval District, Fli-Hawk operated on patrol duties in the Norfolk, Virginia, area for the rest of World War I.
On 31 December 1917, Fli-Hawk was getting underway when she collided with the steamer SS Gratitude in Norfolk Harbor. Fli-Hawk sank three hours later, but was raised, repaired, and returned to service.
Fli-Hawk was decommissioned on 8 February 1919 and returned to her owner.
