The brief career of Gloster’s F.9/37 is greatly overshadowed by the manufacturer’s later successes. Tony Buttler delves into the history of this lesser known prototype
A contemporary to Westland’s fearsome-looking Whirlwind, the Gloster F.9/37 was a moderately small twin-engined fighter designed as World War Two approached. Both types were armed with cannon rather than machine guns, and one F.9/37 later flew with the Whirlwind’s Rolls-Royce Peregrine powerplant. However, the Gloster type never entered production and subsequently gains little recognition today.
