The USS Pike (SS-6), also known as A-5, was a Plunger-class submarine built for the United States Navy in the early 20th century. Laid down on December 10, 1900, by Union Iron Works in San Francisco, she was launched on January 14, 1903, and commissioned on May 28, 1903, at Mare Island Navy Yard. As a Plunger-class vessel, Pike measured approximately 63 feet 10 inches (19.5 meters) in length, with a beam of 11 feet 11 inches (3.6 meters) and a mean draft of 10 feet 7 inches (3.2 meters). She displaced 107 long tons (109 tons) on the surface and 123 long tons (125 tons) submerged. Her crew consisted of one officer and six enlisted men. Designed primarily for experimental and training roles, Pike operated out of Mare Island and participated in important relief efforts following the 1906 San Francisco earthquake. She was decommissioned later that year but was recommissioned in June 1908 to serve with the Pacific Torpedo Flotilla along the U.S. West Coast. In 1911, she was renamed A-5. In 1912, A-5 moved to Puget Sound Navy Yard and was placed in reserve. She was transported as deck cargo aboard the collier Hector to the Philippines in 1915, arriving at Olongapo and being recommissioned shortly afterward. During World War I, A-5 patrolled the waters near Manila Bay and was briefly sunk on April 15, 1917, at the Cavite Navy Yard due to a slow leak in her ballast tank. She was raised and repaired, continuing her patrol duties during the war. A-5 was reclassified with the hull number SS-6 in 1920 and was decommissioned on July 25, 1921. Her maritime service included early U.S. submarine development, coastal defense, and wartime patrols in the Pacific, marking her as a notable vessel in the evolution of American undersea warfare. She was ultimately struck from the Naval Vessel Register in 1922, earmarked as a target vessel, and serves as an important part of early submarine history.
