The Eagle-class patrol craft were anti-submarine vessels of the United States Navy that were built during World War I using mass production techniques. They were steel-hulled ships smaller than contemporary destroyers but having a greater operational radius than the wooden-hulled, 110-foot (34 m) submarine chasers developed in 1917. The submarine chasers' range of about 900 miles (1,400 km) at a cruising speed of 10 knots (19 km/h; 12 mph) restricted their operations to off-shore anti-submarine work and denied them an open-ocean escort capability; their high consumption of gasoline and limited fuel storage were handicaps the Eagle class sought to remedy.
