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.

Pfalz E.V

  The Pfalz E.V used a 100 hp Mercedes D.I in-line six-cylinder engine cooled by a nose-mounted, automobile-type radiator, giving it a distinctive appearance. Based on the E.IV airframe, the more streamlined E.V was slightly faster despite its lower power, but the basic pre-war Morane-Saulnier design was incapable of further development. To offset the extra weight of the liquid-cooled engine, only a single machine gun was mounted. By the time the E.V passed its Typenprufung (Type Test) in July 1916, the first German biplane fighters, Halberstadt D.IIs, were already at the front. Because the performance and maneuverability of the E.V were inferior to the Halberstadt biplane already in service, only 20 Pfalz E.V aircraft were built, mostly to keep the Pfalz factory active, and a maximum of only three were recorded in the frontline inventory in June 1916. Two were later transferred to the navy.
