The Cannon class was a class of destroyer escorts were built by the United States primarily for ocean anti-submarine warfare escort service during World War II. The lead ship, USS Cannon, was commissioned on 26 September 1943 at Wilmington, Delaware. Of the 116 ships ordered 44 were canceled and six commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting the vulnerable cargo ships. BRP Rajah Humabon (FF-11) of the Philippine Navy, formerly USS Atherton, remains the only confirmed commissioned ship of this class as of 2016.

The class was also known as the DET type from their Diesel Electric Tandem drive. The DET's substitution for a turbo-electric propulsion plant was the primary difference with the predecessor Buckley ("TE") class. The DET was in turn replaced with a direct drive diesel plant to yield the design of the successor Edsall ("FMR") class.

A total of 72 ships of the Cannon class were built.

During World War II, six ships of the class were earmarked for the Free French Naval Forces and a further eight were transferred the Brazilian Navy.

After the end of World War II the United States Navy transferred many ships of the Cannon class to other navies
