The second USS Osceola, later AT-47, was a United States Navy armed tug in commission in 1898 and in combat in the Spanish–American War, and from 1911 to 1922.

Completed in 1897, Winthrop was purchased by the U.S. Navy from Staples Coal Company on 21 March 1898 and commissioned on 4 April 1898, as the United States made final preparations for the approaching war with Spain.

On 16 March 1912, she would tow the hulk of the USS Maine, whose 1898 destruction precipitated the Spanish–American War, to its final resting place in international waters.

In 1920, as part of the U.S. Navy's institution of an alphanumeric hull classification system, she was designated AT-47 as a seagoing tug.

In 1921 Osceola became part of a special U.S. Navy squadron organized to patrol Caribbean waters to promote friendly relations between the United States and Latin America.
