    The Aero A.11 was a successful, multi-faceted performer for the Czech Army Air Force in the interwar years between World War 1 and World War 2. Equally respected for its adaptability and capability, the A.11 was designed from the outset as a multi-purpose airframe to replace the aging series of aircraft still in service at the time. In the end, the Aero A.11 would see no fewer than 20 different variant types, owing to the adaptable design envisioned when the aircraft first flew in 1923.

    The A.11 was of a basic design. The pilot and gunner sat in tandem along the box-type fuselage. The biplane wing structure was fitted just in front and around the pilot's position with the single liquid-cooled engine mounted forward. A single .303 caliber machine gun was fitted for self defense.

    The Aero A.11 was seen in its typically reconnaissance platforms but was equally adept in the role of day or night bombing. Other notable variants would go on to include the ever-important target tug (in the form of the A.29) and several day and night bombers of similar design. The A.29 target-tug variant would also form the basis for the first Czech sea-operating float plane.
