USS Somers may refer to:
The third USS Somers (Torpedo Boat No. 22/TB-22/Coast Torpedo Boat No. 9), a steel torpedo boat built as a private speculation by Friedrich Schichau, Elbing, Germany, was launched in 1897 as yard No. 450; purchased for the United States Navy on 25 March 1898; commissioned on 28 March 1898, Lieutenant John J. Knapp in command; and named Somers the next day.
Purchased through Schichau's London representative as the U.S. prepared for a possible war against Spain, Somers sailed for England on 30 March, manned by a German contract crew. On 5 April, she arrived at Weymouth, whence she was to be escorted across the Atlantic by the gunboat Topeka. However, the British crew contracted for the voyage thought Somers was unsafe and refused to take her out to sea. A second attempt to sail also failed, and the torpedo boat was ordered laid up at Falmouth until the conclusion of the Spanish American War.
Somers arrived at New York, on board SS Manhattan, on 2 May 1899 and remained at the New York Navy Yard until 8 October 1900, when she got underway for League Island, Pa. Subsequently decommissioned there, she was reassigned to the Reserve Torpedo Flotilla at the Norfolk Navy Yard, where she was based from 1901-1909. On 26 June 1909, she was loaned to the Maryland Naval Militia and made periodic training cruises from Baltimore until returned to the Navy in 1914.
The second USS Somers was a brig in the United States Navy during the John Tyler administration which became infamous for being the only U.S. Navy ship to undergo a mutiny which led to executions.
Somers was launched by the New York Navy Yard on 16 April 1842 and commissioned on 12 May 1842, with Commander Alexander Slidell Mackenzie in command.
After a shakedown cruise in June–July to the Spanish colony of Puerto Rico and back, the new brig sailed out of New York harbor on 13 September 1842 bound for the Atlantic coast of Africa with dispatches for frigate Vandalia. On this voyage, Somers was acting as an experimental schoolship for naval apprentices.
After calls at Madeira, Tenerife, and Praia, looking for Vandalia, Somers arrived at Monrovia, Liberia on 10 November and learned that the frigate had already sailed for home. The next day, Cdr. Mackenzie headed for the Virgin Islands hoping to meet Vandalia at St. Thomas before returning to New York.
