Parschau's aircraft also had an aft-cockpit-located main fuel tank. The aircraft would later be taken back by Fokker for factory armament installation trials, which also allowed the wing location to be lowered to mid-fuselage, a position that would become standard for all regular production Eindeckers. The initial batch of five M.5K/MG production prototypes were completed by the Fokker factory with the shoulder-mount wing mounting location that the original M.5s had used.

All Eindeckers used a gravity fuel tank which had to be constantly filled by hand-pumping from the main fuel tank, which starting with the Fokker E.II

Total production for the entire Fokker E.I through E.IV series was 416 aircraft (one aircraft's type is unknown).

Operational history

The first Eindecker victory, though unconfirmed, was achieved by Leutnant Wintgens on 1 July 1915 when, while flying one of the five M.5K/MG production prototype aircraft, numbered 'E.5/15', he forced down a French Morane-Saulnier L two seat "parasol" monoplane. By this time the first E.Is were arriving as supplementary equipment, one per unit as "attached" aircraft, for the ordinary Feldflieger Abteilung

 - initially to provide escort protection for their usual quantity of six two-seat reconnaissance biplanes per unit.

Three days after his "unconfirmed" victory, Wintgens would down another "Morane Parasol" with the same E.5/15 aircraft, and a full fortnight after his initial engagement, on 15 July 1915, he became the first Eindecker pilot to be credited with such an official victory.

Boelcke scored the most Eindecker victories; 19 out of his final tally of 40, his last coming on 27 June 1916. Immelmann had the second-highest Eindecker score, having achieved all his 15 victories in the type before being killed when his E.III broke up in June 1916. 11 pilots scored five or more victories in the Eindecker. Boelcke, Immelmann and Wintgens all received Germany's highest military decoration, the Pour le Mérite
