Short Knuckleduster Photo Gallery
    Introduced in 1933, the Short S.18 Knuckleduster was a General Purpose Open Sea Patrol Flying Boat that was powered with an experimental steam-cooled, cast block Rolls-Royce Goshawk engine. The conspicuous cooling condensers were mounted vertically above the engine nacelles. It never saw military service, but it led to the development of the successful Empire and Short Sunderland aircraft. Only one aircraft was built.
