11/30/2010. Essentially similar to the D.XIII, the D.XIV was ordered by Idflieg in April 1918 to evaluate the new Goebel Goe III eleven-cylinder rotary engine of 160 hp. Fitted with the standard twin 0.311 in (7.9 mm) LMG 08/15 gun armament, the prototype D XIV was completed in time to participate in the second D-type contest in May 1918. Flying was strictly limited by the recalcitrant engine, and this, in accordance with competition protocol, eliminated the D.XIV from further consideration as a production type. No data relating to the D.XIV are available.
