The Westland C.O.W. Gun Fighter was an attempt to produce a fighter aircraft armed with a heavy calibre gun. The Coventry Ordnance Works (COW) 37 mm automatic gun was used, which had been developed for this purpose some years earlier.
The Westland Wizard was Westland Aircraft's first attempt to produce a monoplane fighter. The project was privately funded and the prototype design was done in the spare time of the company's engineers.[1] This all happened during 1926, with high-speed performance as the primary goal.
