The wooden-hulled vessel was built in 1918–19 as the Yomachichi by the Oscar Daniels Shipbuilding Company of Tampa, Florida[1] for the United States Shipping Board.

[2] Ocelot transited the Panama Canal and, following a brief stop in San Diego, arrived at Pearl Harbor to undergo conversion to flagship for Service Squadron 10.

[4] The conversion was completed in October, and Ocelot sailed via Eniwetok for Ulithi where she spent the next six months providing an administrative post at the advanced base.

[6] She was eventually refloated,[5] but on 9 October during Typhoon Louise she was struck by the repair ship Nestor (ARB-6), which severed her stern section.

[5] Ocelot was returned to the custody of the WSA on 5 April 1946[5] and her hulk was sold by the Maritime Commission, along with seven other wrecks and five civilian liberty ships, to China Merchants and Engineers, Inc. for scrapping on 19 February 1948.
