Ship Designation: 
Date Lost: 
Friday, June 14, 1918
Lost in the Bermuda Triangle
Except for a voyage to Halifax, Nova Scotia, Cyclops served along the east coast until January 9, 1918 when she was assigned to Naval Overseas Transportation Service. She then sailed to Brazilian waters to fuel British ships in the south Atlantic, receiving the thanks of the State Department and Commander-in-Chief, Pacific. She put to sea from Rio de Janiero February 16, 1918 and after touching at Barbados on 3 and 4 March, was never heard from again. Her loss with all 306 crew and passengers, without a trace, is one of the sea's unsolved mysteries.
