Mosquito production continued until 1948, by which time work had begun on DHA's third indigenous design, the DHA-3 Drover. On 29 June 1949, following selection of the type by the RAAF in 1946, the first of 190 licence-built DH.100 and DH.115 Vampires had its first flight with DHA's chief test pilot Brian "Black Jack" Walker at the controls. Production of the Vampire continued until 1960, the same year the parent company was purchased by Hawker Siddeley. At this time the company also entered the general aviation market when it became the Australian distributor for Beechcraft in 1959. Following the absorption of de Havilland by Hawker Siddeley, DHA was renamed Hawker de Havilland (HdH) in 1965. In 1959 the de havilland marine division was formed.
