AGO ("AktienGesellschaft Otto") Flugweugwerke of the German Empire was founded in Munich during 1911 and managed as existence until the end of World War 2 in 1945. As early as 1913, under the Otto name, the company put forth a pusher biplane. From this work spanned a series of other multi-winged aircraft of similar form and function that would soon be pressed into military service during the fighting of World War 1 (1914-1918).
With the war already underway by January of 1915, many aircraft were trialed and adopted by all sides, as powers looked to gain the advantage through use of these new-fangled aerial devices. In June of 1915, AGO was able to sell a new biplane type to the German Air Service and the Kaiserliche Marine (Navy) - the "AGO C.I".
The C.I utilized a typical biplane winged arrangement in which one primary member sat over the other. Struts were parallel and "bays" were created between these structures supporting the wings. As with other early-form reconnaissance platforms of the war, the C.I relied on a pod-and-boom fuselage arrangement in which the crew, armament, engine, fuel stores, and avionics were held in a centralized pod making up the fuselage while a twin-boom tail arrangement was used to support the tailplanes. The tailbooms connected to the mainplanes at the struts for added support and extended beyond the wing leading edges some. The crew numbered two, pilot and observer, with the observer positioned ahead of the pilot. On some aircraft, the observer was granted use of a single 7.92mm Parabellum air-cooled machine gun set atop a flexible mounting. The ground-running gear was made up of a four-wheeled arrangement for the best possible balance. These legs were interconnected by a network of struts under the aircraft and its lower mainplane member. At least one C.I example was reworked with floats to serve the German Navy in the maritime patrol role as the "C.I-W".
In an effort to provide the crew with the best possible vision out-of-the-cockpit - particularly to the front and sides - the engine was fitted at the rear of the pod so the propellers were arranged in a "pusher" configuration - literally pushing air so as to push the aircraft through the sky. The engine of choice became the readily-available Mercedes D.III outputting 158 horsepower and driving a two-bladed wooden propeller at the rear.
Structural dimensions included an overall length of 29.5 feet and a wingspan of 49.1 feet.
In practice, the aircraft could reach speeds of 90 miles-per-hour, which was good for an early-form biplane aircraft. Range was out to 300 miles giving the platform a good "reach". Its service ceiling was 16,000 feet.
