The Pfalz Dr.II was a German triplane fighter prototype of World War I built by Pfalz Flugzeugwerke.

Development

[edit]

The Pfalz Dr.II was a lightweight development of the Dr.I with a reduced wing area. The first prototype had a 110 hp (81 kW) Oberursel Ur II engine, and the second prototype (Dr.IIa) used a Siemens-Halske Sh I engine, which developed the same power. However, the Dr.II did not enter production.[1][2]
