Fokker E.III

The Fokker E.III was the main variant of the Eindecker fighter aircraft of World War I.

The E.III was basically an E.II fitted with larger, newly designed wings that had a slightly narrower chord of 1.80 meter (70-7/8 in), compared to 1.88 meter (74 in) on the earlier Eindecker’s, 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, it had a larger 81 l (21.5 gal) drum-shaped main fuel tank just behind the cockpit, 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 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.
