The Napier Javelin was a British six-cylinder inline air-cooled engine designed by Frank Halford and built by D. Napier & Son. First flown in March 1934 in the prototype of the Percival Mew Gull racing aircraft, the engine was also used in the Spartan Arrow biplane and the Percival Gull.
The six cylinders were arranged inverted and inline. Unlike the similar de Havilland Gipsy Six the poppet valves were operated by a single gear driven overhead camshaft.
