The Siddeley Puma is a British aero engine developed towards the end of World War I and produced by Siddeley-Deasy. The first Puma engines left the production lines of Siddeley-Deasy in Coventry in August 1917, production continued until December 1918. In operational service, the engine was unreliable and failed to deliver its rated power. At least 4,288 of the 11,500 ordered engines were delivered, orders were cancelled following the Armistice. Production was continued under the name Armstrong Siddeley Puma when the manufacturer was bought by Armstrong Whitworth and became Armstrong Siddeley.
