Design and development
The Wolf was a two-bay biplane of unorthodox design, with the fuselage mounted between the two sets of wings. No production order was placed, and the three machines built served their days at the Royal Aircraft Establishment at Farnborough as experimental testbeds.
Alongside the RAF's order in 1923, Armstrong Whitworth also built two for the RAF Reserve Flying School at Whitley, and a final, sixth aircraft in 1929. As trainers, they proved popular with pilots, although less so with ground crews for whom the rigging and undercarriage were awkward to maintain.
All Wolves were retired from service in 1931 and all but the most recently built were scrapped. The final aircraft was taken to Hamble for use as an instructional airframe.
