[edit] Design and development
In 1919 the Royal Navy had an urgent need for a three-seat spotter/reconnaissance aircraft. The solution was a conversion of the Airco DH.9 to fit a third-crew member. The prototype was produced as the Armstrong Whitworth Tadpole.
The production contract was won by Westland Aircraft, who built 36 aircraft as the Westland Walrus with a 450 hp (336 kW) Napier Lion II engine. Other changes from the DH.9 included jettisonable main landing gear, flotation bags, arresting gear and easily detachable wings.
