Scrapped in 1930 Lake went out of business in 1925. Generally similar to R class, but smaller and reverted to 18-inch torpedo tubes. Fired Mark 10 torpedoes and traveled 5,000 miles (8,000 km) at 10 knots (5.1 m/s).ĭesigned by Simon Lake. Larger conning tower to serve as commanding officer's battle station. A poor tandem engine design caused the boats to be decommissioned by 1923 and scrapped in 1930. Twice the size of any concurrent or past U.S. Prototype "fleet submarines"-submarines fast enough (21 knots (11 m/s)) to travel with battleships. Modified boats proved to be disappointing and were scrapped in 1930 Lake went out of business in 1925. O-11 through O-16 (built by Lake Torpedo Boat Company) also known as the "modified O-class". Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. First submarines with reliable diesel engines. Used for coastal patrol.Įach cost $550,000. Considered failure by the submarine community. Designed for coastal defense.ĭouble-hull design. 17 ordered by the Imperial Russian Navy, 11 delivered. G-1 (SS-19½) was given the number 19½ because SS- numbers were given after her decommissioning she was between SS-19 & SS-20.ģ originally ordered by U.S. In 1920, the class was designated SS-20–SS-23.

Also, boats are modified, sometimes extensively, while in service, creating departures from the class standard. Minor variations occur as improvements are incorporated into the design, so later boats of a class may be more capable than earlier. Submarines of the United States Navy are built in classes, using a single design for a number of boats.
