| Variants | |||
| Pfalz experimental D types | During the development of the D.XII, Pfalz produced several Pfalz D.III-derived prototypes with SPAD-type wings and Windhoff "ear" radiators. | ||
| Pfalz D.XIIf | The overcompressed BMW IIIa engine would have provided improved performance in the D.XIIf variant. Records show that Pfalz received 84 such engines between July and October 1918, but there is no photographic evidence of any production D.XII equipped with the BMW IIIa. In his autobiography, Anthony Fokker claimed that pilots deliberately wrecked D.XIIf aircraft so the engines could be salvaged and installed on Fokker D.VIIs. | ||
| Pfalz D.XIV | The Pfalz D.XIV was a derivative of the D.XII, utilizing the same fuselage and basic wing structure. The D.XIV differed primarily by replacing the 180 hp Mercedes D.IIIaü with the 200 hp Benz Bz.IVü, a substantially heavier engine. To cope with the increased power and weight, the D.XIV featured longer span wings and an enlarged vertical stabilizer. Enlarged ailerons were used to maintain rate of roll. A few prototypes were tested at the second Adlershof competition and a small production order ensued. Production was quickly terminated, however, and the D.XIV did not see active service. The D.XIV did not offer an appreciable increase in performance over the D.XII, and the Benz Bz.IVü engine was needed for reconnaissance aircraft. | ||
