The Napier Javelin was a British six-cylinder inverted inline air-cooled engine designed by Frank Halford and built by D. Napier and Son for light aircraft. Napier saw a market for such engines in 1930 and gave the project the go-ahead in 1932; it was first offered as the E97 and relaunched in 1933 as the Javelin, with a single gear-driven overhead camshaft working the poppet valves. The Javelin I gave 150 horsepower from 8.2 litres and the Javelin III 160. It first flew in March 1934 in the prototype Percival Mew Gull and was also used in the Spartan Arrow and the Percival Gull, but few were sold, and it was withdrawn in 1935 against the de Havilland Gipsy Six.
