The Short Admiralty Type 81 was a series of British two-seat floatplanes built prior to the First World War and used by the Royal Naval Air Service in the early years of the war. They were powered by 160 hp (119 kW) Gnome rotary engines and had folding wings to aid storage on ship hence the popular name Short Folder shared with a number of other seaplanes made by Short Brothers.
