The Rudderow-class destroyer escorts were destroyer escorts launched in the United States in 1943 to 1945. Of this class, 22 were completed as destroyer escorts, and 50 were completed as Crosley-class high speed transports and were re-classified as high speed transport APDs. One ship was converted to an APD after completion. They served in World War II as convoy escorts and anti-submarine warfare ships.

The lead ship was USS Rudderow which was launched on 14 October 1943. The ships had General Electric steam turbo-electric drive engines. The ships were built at various shipyards in the United States, including the Philadelphia Navy Yard and Defoe Shipbuilding Company. They were very similar to the Buckley class, having the same hull and machinery. The main differences were the Rudderows had two 5-inch (127 mm) guns and two twin-40 mm mounts, instead of the three 3-inch (76 mm) guns and one twin-40 mm or one quad 1.1-inch (28 mm) mount of the Buckleys. The class was also known as the TEV type from their Turbo-Electric drive and 5-inch (V) guns.

The final 180 of the class were canceled near the end of the war. After World War II, some of the surviving units of this class were transferred to Taiwan, South Korea, Chile, Colombia, Mexico, and other countries. The rest were retained by the US Navy's reserve fleet until they were decommissioned.
