PFALZ E V Germany

  Although, by early 1916, the more rugged and manoeuvrable biplane configuration was demonstrating a clear superiority over the monoplane in the fighting role, the Pfalz Flugzeug-Werke persisted with the latter and developed the E V and E VI. The E V, which completed its Typen-Prufung in July 1916, employed an essentially similar airframe to that of the E IV, this being mated with a 105 hp Daimler D I six-cylinder water-cooled engine, armament reverting to a single LMG 08/15 machine gun. Twenty E Vs were built, but the advent of more efficient and more powerful biplanes rendered the E V obsolescent prior to delivery and only three saw frontline service.
