The Cannon class 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 (DE-99) 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.

The class was also known as the DET type from their Diesel Electric Tandem drive.^[1] The DET's substitution for a turbo-electric propulsion plant was the primary difference with the predecessor Buckley ("TE") class.^[2] The DET was in turn replaced with a direct drive diesel plant to yield the design of the successor Edsall ("FMR") class.^[3]

BRP Rajah Humabon (PF-11) of the Philippine Navy, formerly the USS Atherton (DE-169), remains as the only confirmed commissioned ship of this class as of 2013.
