Westland Wapiti


The Wapiti was a two-seat general-purpose biplane incorporating in its design several de Havilland D.H.9A component parts including wings as requested by the Air Ministry. The prototype first flew in March 1927 and the initial order for 25 production Mk I included one specially modified aircraft with a more luxurious rear cockpit for the Prince of Wales to fly in.

Mk I were powered by 313kW Bristol Jupiter VI engines, but subsequent Mk II and Mk IIA had 343kW Jupiter VI and 391.2kW Jupiter VIIIF or similar engines respectively.

The Mk.II switched to metal construction.

Small numbers of lengthened Wapiti V and unarmed Mk VI trainers brought total production for the RAF to 501; while the type was also adopted by Australia, South Africa (also built under licence), Canada, India and China.
