The Sopwith Pup was a British military fighter biplane that served with the Royal Flying Corps and Royal Naval Air Service during the First World War. It became particularly well regarded for its pleasant handling and manoeuvrability. Beyond land combat, the Pup took part in experiments that helped establish aircraft operations from ships.[1]Sopwith PupRAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details
Frontline service
Pups reached the Western Front in the autumn of 1916. Their agility gave British pilots a useful advantage in close combat, and the type contributed to Allied fighter operations until newer German aircraft changed the balance during 1917. The Pup served with both British air services at home and overseas.[1]Sopwith PupRAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details
Its informal name was disliked by officials, who preferred Sopwith Scout. The attempted change failed to displace the familiar nickname. The name subsequently became part of the wider association between Sopwith aircraft and animal names, including Camel and Dolphin.[1]Sopwith PupRAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details[2]The Sopwith Menagerie, 1915–1916RAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details
Naval experiments
The Pup's handling made it attractive for trials from small shipboard platforms. Aircraft were flown from platforms constructed on cruiser gun turrets, extending the possibilities for scouting and air defence at sea beyond the use of floatplanes.[1]Sopwith PupRAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details
On 2 August 1917, Squadron Commander Edwin Dunning landed a Pup aboard HMS Furious, a landmark in carrier aviation. The experiment remained extremely dangerous: Dunning died when a later landing attempt ended with his aircraft falling over the side of the ship.[1]Sopwith PupRAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details
Training and development
As frontline demands outgrew the Pup, aircraft continued in flying schools. The RAF Museum records their use for teaching aerial fighting and notes that instructors sometimes retained examples for personal flying. Aircraft at the Central Flying School and School of Special Flying acquired distinctive decorative markings.[2]The Sopwith Menagerie, 1915–1916RAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details
The Pup also formed part of Sopwith's development background for subsequent fighters. The Triplane retained a related fuselage and similar armament while exploring a very different wing arrangement. That progression connects the Pup's straightforward biplane layout with the rapid experimentation in fighter design during 1916 and 1917.[2]The Sopwith Menagerie, 1915–1916RAF Museum · rafmuseum.org.uk · Accessed 2026-09-13Open source details
