The Martinsyde F.4 Buzzard was developed as a powerful and fast biplane fighter for the Royal Air Force (RAF), but the end of the First World War led to the abandonment of large-scale production. Fewer than 400 were eventually produced, with many exported. Of particular note was the Buzzard's high speed, being one of the fastest aircraft developed during World War I.
