It retained the same 100 hp Oberursel U.I engine but had a larger 21.5 gal main fuel tank which increased the Eindecker's endurance to about 2½ hours; an hour more than the E.II. Most E.IIIs were armed with a single Spandau LMG 08 machine gun with 500 rounds of ammunition however after the failure of the twin-gun Fokker E.IV as a viable successor, some E.IIIs were fitted with twin guns. Fokker production figures state that 249 E.IIIs were manufactured however a number of the 49 E.IIs were upgraded to E.III standard when they were returned to Fokker's Schwerin factory for repairs.
