The E.III was basically an
E.II fitted with larger, newly designed wings that had a slightly narrower
chord of 1.80 meters ( in), compared to 1.88 meters (74 in) on the earlier Eindeckers, going back to Fokker's original
M.5 monoplane aircraft. The E.III retained the same 75 kW (100 hp)
Oberursel U.I engine, and therefore also used the larger-diameter "horseshoe" pattern cowling that also mandated the inclusion of the E.II's
soffit-like extensions to the sides of the upper nose sheet metalwork, but had a larger 81 L (21.5
gal) drum-shaped main fuel tank just behind the cockpit, which increased the
Eindeckers endurance to about hours, an hour more than the E.II. Most E.IIIs were armed with a single 7.92 mm (.312 in)
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. ==Operational history==
