Like many of Fokker's projects, the D.VII
was designed almost casually. It's historical position as World War I's
most famous fighter is therefore especially remarkable. It's ability to
"hang on the prop" — in reality, a very slow, controlled climb - and to
perform exceptional manoeuvres without airframe damage made it a
formidable, if not especially fast, opponent. It was the only aircraft
type specifically mentioned in the Armistice Agreement, Article IV of
which notes..."to be handed over... especially all machines of the
D.VII type." This unique notation, Tony Fokker's desperate, frantic,
and ultimately successful effort to smuggle airframes and parts into
his native Holland for later sale, Travel Air's later clones of the
fighter, and the use of the type by many nations into the 1930's
constitute unique but true part of the legend of Fokker's D.VII.
Reinhold Platz designed the D.VI and D.VII side-by-side for the
January, 1918 D-class (single seat biplane fighter) competitions at
Aldershof. No prototype existed until less than sixty days before the
"fly-off", and only one short hop was made before entry. It was
anticipated that the aircraft which won the competition would turn the
tide in the air. The Fokker won handily, but never did regain real
supremacy over the Western Front. At that stage of the war, Allied
production could bury anything the Germans could produce, and all any
single type could do was pick away at local superiority during
short-term operations.
The airframe was designed to accept the Mercedes D-III or the 185 h.p.
B.M.W. powerplants. Fuselage construction was box-girder, of welded and
braced steel tube, covered with metal forward, plywood and fabric at
the rear. The single-bay wings were wooden, two box-spar units, using
N-form interplane struts with no external wire bracing. In fact, the
wings were of true cantilever design, and the struts were there solely
as a concession to traditionalists who refused to fly in or consider
for procurement any aircraft lacking them. They were not necessary. As
usual on Fokkers, an airfoil section enclosed the undercarriage axle.
D.VII's began to reach the Western Front in April of 1918. Fokker
produced 366 aircraft, most coming from Albatros and Scneldermohl. A
whole new crop of German aces and new kills for the old veterans
resulted from the introduction of the new, agile fighter.
Production did not end until several years after the war, and postwar
powerplants imbued the D.VII with splendid performance, such that it
sold well even in a world cluttered with cheap surplus fighters.
