The USS B-1 (SS-10), also known as "Submarine Torpedo Boat No. 10," was the lead vessel of her class of early 20th-century American submarines. Built by the Fore River Shipbuilding Company under a subcontract from the Electric Boat Company, she was laid down on September 5, 1905, in Quincy, Massachusetts, and launched on March 30, 1907. She was commissioned on October 18, 1907, and served primarily as a training vessel. The B-1 measured 82 feet 5 inches (25.12 meters) in length, with a beam of 12 feet 6 inches (3.81 meters) and a mean draft of 10 feet 7 inches (3.23 meters). Displacing 145 long tons (147 tonnes) on the surface and 173 long tons (176 tonnes) submerged, she was crewed by one officer and nine enlisted men. Her operational depth was 150 feet (45.7 meters). Powered for surface travel by a 240-horsepower gasoline engine and by a 115-horsepower electric motor when submerged, she could reach speeds of 9 knots (17 km/h) on the surface and 8 knots (15 km/h) underwater. Her range was approximately 540 nautical miles (1,000 km) at 9 knots on the surface. The vessel was armed with two 18-inch (450 mm) torpedo tubes located in the bow, carrying two reloads for a total of four torpedoes. Her operational history included patrols along the Atlantic coast and later in the Philippines, where she was transported aboard the collier Hector to Olongapo, Luzon, arriving in 1915. She was assigned to the First Submarine Division of the Asiatic Fleet, serving as the flagship under division command. Throughout her service, B-1 contributed to submarine tactics development, participating in diving tests and torpedo exercises, notably in the waters around the Philippines during World War I. She faced operational hazards such as hull pressure limits and the dangers of gasoline fumes from her internal combustion engine, which nearly led to disaster in 1916. Despite never engaging in combat, her operational experience helped refine submarine warfare techniques. Decommissioned at Cavite on December 1, 1921, B-1 was later used as a target during destroyer gunnery practice, and her name was struck from the Navy list in January 1922. Her service laid important groundwork for the development of submarine tactics and contributed to the evolution of the U.S. Navy's undersea fleet.
