The Gloster Gamecock was a British biplane fighter developed in the 1920s by Gloster Aircraft Company.
It was an improved version of the Gloster Grebe, featuring a Bristol Jupiter radial engine for better reliability and performance.
The Gamecock was praised for its maneuverability and speed, but it had a high accident rate, leading to a relatively short service life with the Royal Air Force (RAF).
However, it remained in use longer with the Finnish Air Force, where it was produced under license as the Kukko and even saw action during the Winter War (1939–1940) against the Soviet Union.
