The Kondor E 3, sometimes erroneously known as E.III, was a German single seat, monoplane fighter aircraft designed and built close to the end of World War I.
The result was a very strong structure; Kondor claimed that the slight though clearly visible rib protrusion also improved the aerodynamics.
Behind the engine, the fuselage was flat-sided, with the single open cockpit under a large cut-out in the wing's trailing edge for enhanced visibility, tapering to the tail under shallow, rounded decking.
The E 3 had a fixed, conventional undercarriage, the mainwheels on a single axle with V-strut legs to the lower fuselage and cross-wire braced.

[2] One senior pilot there reckoned the Kondor the best machine present; it was judged as having flight characteristics only marginally less good than the recently ordered Siemens-Schuckert D.IV biplane and showed none of the high-speed parasol wing vibrations experienced with the Fokker D.VIII.
