| The D.H. 9 was once, aptly, described
as a "D.H. 4 which had been officially
interfered with so as to be suitable
for mass-production and the B.H.P. Beardmore-Halford-Pullinger)
motor". The chief alterations being
the repositioning of the pilot's cockpit
to a point behind the centre section,
and a partially cowled motor with the
radiator beneath the fuselage instead
of behind the airscrew. At the expense
of a lower top speed, the bomb load
was increased by 500 lbs. Widely used
as a day bomber, the D.H. 9 certainly
had its share of troubles, particularly
with the B.H.P. motor, which proved
unreliable and was largely obsolete
by the time the aircraft reached production.
Bombing formations were often reduced
in strength before they crossed the
lines since the motors of some machines
could not develop sufficient power to
enable them to keep station. Despite
these shortcomings the type was produced
on a grand scale, with no less than
2100 being built by the war's end. |
