The Cannon class was a class of destroyer escorts built by the United States primarily for antisubmarine warfare and convoy 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 cancelled and six were commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting vulnerable cargo ships.

With the decommissioning of the Philippine Navy's BRP Rajah Humabon (PS-11) in March 2018; HTMS Pin Klao (DE-413) of the Royal Thai Navy is the only ship of the class in commission.

The class was also known as the DET type from their diesel electric tandem drives.^[1] The propulsion system of the Evarts-class (GMT = General Motors Tandem) was identical. The DET's substitution for a turboelectric 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]

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

• DE-99 through DE-113 (six are French)
• DE-162 through DE-197
• DE-739 through DE-750
• DE-763 through DE-771

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.
