USS Porpoise/A-6 (SS-7), also known as "Submarine Torpedo Boat No. 7", was one of seven Plunger-class submarines built for the United States Navy (USN) in the first decade of the 20th century. She was the third boat in the USN named for the porpoise. Used primarily for training, she was partially disassembled and transported to the Philippines, in 1908. During WWI she was used for harbor defense in Manila Bay.
