The Westland IV first flew on 21 February 1929 at which time it was powered by the 95 hp Cirrus engine. The Wessex of 1930 used more powerful Armstrong Siddeley Genet Major engines as well as some other changes; the two Westland IV were subsequently converted to Wessexes giving 10 aircraft in total.
