The third USS Porpoise (SS-7) was an early Plunger-class submarine in the service of the United States Navy, later renamed as A-6.

She was laid down on 13 December 1900 in Elizabeth, New Jersey at the Crescent Shipyard under the direction of shipyard superintendent, Arthur Leopold Busch. This craft was launched on 23 September 1901, and commissioned at the Holland Torpedo Boatyard at New Suffolk, New York on 19 September 1903, with Lieutenant Charles P. Nelson in command.

Assigned initially to the Naval Torpedo Station at Newport for experimental torpedo firing work, Porpoise entered the New York Navy Yard in September 1904 for repairs and alterations, remaining there until February 1906. Assigned then to the First Torpedo Flotilla on 7 March 1907, she operated at Annapolis, Maryland — temporarily assigned to the United States Naval Academy for instruction of future naval officers — until June. Taken subsequently to the New York Navy Yard, she was decommissioned on 21 April 1908. Partially disassembled, she was then loaded onto the after well deck of the collier Caesar for a voyage to the Philippines as deck cargo along with her sister ship Shark via the Suez Canal.

Arriving at the Naval Station at Cavite, Porpoise was launched on 8 July 1908, and recommissioned on 20 November. Due to the small size of Plunger-class boats, officers and men lived on board the gunboat Elcano.
