The D I was in essence the C II two-seater scaled down as a single-seat fighter. The type was nicknamed Haifisch (shark) for its deep fuselage with the slightly swept upper wing attached directly to it. The D I first flew in July 1916, and was produced in small numbers. The D II began to enter service early in 1917, and was complemented by the D.Ia with a more powerful engine. The D II and D la were not popular in service, pilots complaining about lack of vision and heavy controls.
