The Lebed XII was a Russian military reconnaissance aircraft produced during the First World War for the Imperial Russian Air Force. It was one of the few domestically-designed aircraft to see production in Russia during the war, but was based on designs and techniques learned from Lebed's rebuilding of captured German types. The fuselage was a plywood structure of rectangular cross-section with seating for the pilot and observer in tandem, open cockpits. The wings were built around a pine spar and covered in fabric, and the empennage (tail assembly) was of welded steel tube with fabric covering.
