USS Hetman, a 20-ton motor patrol craft, was built in 1917 at Greenport, Long Island, for the Russian Government. Purchased by the U.S. Navy in August 1917 and commissioned in October under the name Greenport # 277, she was renamed Hetman a month later in recognition of her Russian origins. After initial service in the New York harbor area, she was sent to Miami, Florida, where she was employed in support of aviation operations from December 1917 until the end of the First World War. Subsequently transferred to Key West, Florida, Hetman was stricken from the Navy list in June 1919 and sold in March 1921.
