The Sopwith Triplane was a British single seat fighter aircraft designed and manufactured by the Sopwith Aviation Company during the First World War. Pilots nicknamed it the Tripehound or simply the Tripe. The Triplane became operational with the Royal Naval Air Service in early 1917 and was immediately successful. The Triplane was nevertheless built in comparatively small numbers and was withdrawn from active service as Sopwith Camels arrived in the latter half of 1917. Surviving aircraft continued to serve as operational trainers until the end of the war.

As Described In
Red Baron: Although underpowered, the Triplane is a nimble aircraft, and climbs quickly. It only mounts one machine gun.
Knights of the Sky: In an attempt to push the excellent Sopwith Pup design even further and get more maneuverability, speed, and altitude, Sopwith company produced a triplane version in May of 1916. It was quickly nicknamed "Tripe." The test flights were very successful and resulted in immediate orders from both the RFC and RNAS; in fact, the navy traded its Spad 7s for the new Tripe. The Tripe had an outstanding rate of climb, due to the increased lift provided by the added wing, and was extremely agile and maneuverable, due to the extra control surfaces.
