The Cannon class destroyer escorts were built 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. The class was also known as the DET type from their Diesel Electric Tandem drive.[1] Of the 116 ships ordered 44 were cancelled and 6 commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting the vulnerable cargo ships.

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 2010.
