AD Scout AD Scout Role - Fighter Manufacturer - Air Department Designer - Harris Booth First flight - 1915 Primary user - Royal Naval Air Service - testing only Number built - 4 The AD Scout (also known as the Sparrow) was designed by Harris Booth of the British Admiralty's Air Department as a fighter aircraft to defend Britain from Zeppelin bombers during World War I. Design and development The Scout was a very unconventional aircraft - a biplane with a fuselage pod mounted on the upper wing. A twin-rudder tail was attached by four booms, and it was provided with an extremely narrow-track undercarriage. The primary armament was intended to be a 2-pounder recoilless Davis Gun, but this was never fitted. Four prototypes were ordered in 1915, and two each were built by Hewlett & Blondeau and the Blackburn Aeroplane & Motor Company. Operational history Trials flown by pilots of the Royal Naval Air Service at Chingford proved the aircraft to be seriously overweight, fragile, sluggish, and difficult to handle, even on the ground. The project was abandoned, and all four prototypes were scrapped. Operators 1.
