Airco DH.9

what is it?

The Airco DH.9 (from de Havilland 9) – also known after 1920 as the de Havilland DH.9 – is a British single-engined biplane bomber that was developed and deployed during the First World War. The DH.9 was a development of Airco's earlier successful DH.4, with which it shared many components. These were mated to an all-new fuselage and used the Beardmore Halford Pullinger 230 hp (170 kW) engine, which promised increased performance.
