The de Havilland dh9A went into production in 1918 and 885
aircraft were produced by the end of WW1 by a dozen British
manufactures, the primary contractors being de-Havilland and
Westland. As the DH9A only entered service at the end of
WW1, only four operational squadrons were sent to France.
Although the DH9A's only operated for a short period during
WWI it rapidly gained
a reputation for rugged reliability with their air-crews and
the nickname 'Ninak' (Nin + Ack = Nine +A = 9A).
After WW1 the de Havilland dh9A
bomber along with the
Bristol F2b fighter formed the
backbone of the newly formed Royal Air Force and were used
notably in 'Policing duties' in Iraq from 1921 to 1927. The Airco
DH9a's remained in RAF use up to the end of the
1930's although it was retired from it's original bombing
role in early 1931. When production of the 'Ninak' finally
ceased in excess of 2,500 aircraft had been produced.
Unlicensed production took place in Russia for the Red Air
Force and additional aircraft were made in the US and many
European countries most noticeably those made by SABCA in Belgium and Hispano-Suiza powered
dh9A aircraft in Spain. One notable unusual feature of the
dh9A was a spare tail-wheel tyre carried as standard under
the rear fuselage.
