The Royal Aircraft Factory R.E.5 was a British two-seat reconnaissance and artillery observation biplane designed and built by the Royal Aircraft Factory for the Royal Flying Corps. The R.E.5 was designed as a reconnaissance biplane using the experience of earlier R.E. series aircraft. It was a two-bay equal-span biplane with a fixed tailskid landing gear, with the wheels supported on skids and powered by a nose-mounted 120 hp (89 kW) Austro-Daimler engine driving a four-bladed propeller. The aircraft had two open cockpits with the observer/gunner in the forward cockpit under the upper wing and the pilot aft.
