USS Percival (DD-452) was an experimental United States Navy destroyer who was never laid down and cancelled in 1946.

Percival and sistership Watson were planned to be a variation of the Fletcher-class destroyer, with Percival fitted with an experimental high-pressure boiler system and Watson designed to run on diesel engines, compared to the standard design of 4 oil-burning boilers.^[1]^[2]^[3]^[4]

She was contracted out to Federal Shipbuilding on 1 July 1940. Like her sistership, more pressing matters delayed their construction and were both canceled on 7 January 1946.^[2]^[5] After cancelation, her novel machinery was installed in USS Timmerman, a modifed Gearing-class destroyer, for testing. Timmerman was able to produce 100,000 shaft horsepower (shp) and a top speed of about 40 knots compared to a standard output of 60,000 shp.^[6]^[7]
