The United States D-class submarines were a trio of submarines built for the United States Navy in the first decade of the 20th century. All three ships served during World War I providing training for crews and officers on the US East Coast, before the class was decommissioned and sold for scrap in 1922.
The D-class submarines were enlarged versions of the preceding C class, the first American submarines armed with four torpedo tubes. They were built by the Fore River Shipbuilding Company of Quincy, Massachusetts, under a subcontract from the Electric Boat Company of Groton, Connecticut. They had a length of 134 feet 10 inches (41.1 m) overall, a beam of 13 feet 10 inches (4.2 m) and a mean draft of 12 feet 6 inches (3.8 m). They displaced 288 long tons (293 t) on the surface and 337 long tons (342 t) submerged. The D-class boats had a crew of 1 officer and 14 enlisted men. They had a diving depth of 200 feet (61.0 m).
For surface running, they were powered by two 300-brake-horsepower (224 kW) NELSECO gasoline engines, each driving one propeller shaft. When submerged each shaft was driven by a 130-horsepower (97 kW) electric motor. Two 60-cell batteries provided power when submerged. They could reach 13 knots (24 km/h; 15 mph) on the surface and 9.5 knots (17.6 km/h; 10.9 mph) underwater. On the surface, the boats had a range of 1,179 nautical miles (2,184 km; 1,357 mi) at 9.6 knots (17.8 km/h; 11.0 mph) and 24 nmi (44 km; 28 mi) at 8 knots (15 km/h; 9.2 mph) submerged.
