USS O-2 (SS-63) was one of 16 O-class submarines built for the United States Navy during World War I.
The O-class submarines were designed to meet a Navy requirement for coastal defense boats. The submarines had a length of 172 feet 3 inches (52.5 m) overall, a beam of 18 feet 1 inch (5.5 m) and a mean draft of 14 feet 5 inches (4.4 m). They displaced 521 long tons (529 t) on the surface and 629 long tons (639 t) submerged. The O-class submarines had a crew of 29 officers and enlisted men. They had a diving depth of 200 feet (61.0 m).
For surface running, the boats were powered by two 440-brake-horsepower (328 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 370-horsepower (276 kW) electric motor. They could reach 14 knots (26 km/h; 16 mph) on the surface and 10.5 knots (19.4 km/h; 12.1 mph) underwater. On the surface, the O class had a range of 5,500 nautical miles (10,200 km; 6,300 mi) at 11.5 knots (21.3 km/h; 13.2 mph).
The boats were armed with four 18 inch (450 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes. The O-class submarines were also armed with a single 3"/50 caliber deck gun.
O-2 was laid down on 27 July 1917 by the Puget Sound Navy Yard. She was launched on 24 May 1918, and commissioned at Puget Sound on 19 October 1918 with Lieutenant Commander F. T. Chew in command.
