USS O'Bannon (DD-177) was a Wickes-class destroyer built for the United States Navy during World War I.
The turbines were designed to produce a total of 27,000 shaft horsepower (20,000 kW) intended to reach a speed of 35 knots (65 km/h; 40 mph).
The ships carried 225 long tons (229 t) of fuel oil which was intended gave them a range of 2,500 nautical miles (4,600 km; 2,900 mi) at 20 knots (37 km/h; 23 mph).
O'Bannon sailed out of San Diego for exercises and training maneuvers along the coast of California and in Hawaiian waters throughout her career.
In the spring of 1920 she conducted experiments with torpedoes, and then was in reserve commission from June to November, when she resumed her training schedule.
