The Albatros Dr.II was a German prototype single-seat fighter triplane, the sole example of which flew in the spring of 1918. It was similar in many respects to the D.X biplane, employing amongst other features the same 145 kW (195 hp) Benz Bz.IIIbo engine and twin 7.92 mm (.312 in) machine guns. The three pairs of wings were sharply staggered, braced by broad I-struts and shared parallel chords. All three pairs were equipped with ailerons, linked by hinged struts.
