Description

The DH9 was once, aptly, described as a DH4 that 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 pilots cockpit to a point behind the centre section and a partially cowled motor with the radiator beneath the fuselage rather than behind the air screw. At the expense of top speed, the  load was increased by 500 lbs. The aircraft were slow and the BHP engine prone to failures. However over 2, 100 were produced by the end of the war.
