 Nevertheless, the Fokker Dr.I was the winner of the contest, which is not surprising considering that it was the only aircraft entered that was designed from the outset as a triplane, as opposed to being a quickly-adapted biplane.About a dozen Dr. Is were built and used operationally for some time.The final major production model was the Pfalz D.XII, a development of the D.III that abandoned the sesquiplane configuration in favor of two-bay wings, similar in appearance to what looked like two-bay wings on the French SPAD fighters designed by Louis Béchereau.
