The Hawker F.20/27 was a British fighter design built to an Air Ministry specification for an interceptor in the late 1920s. It was a single-seat biplane powered by a radial engine; the very similar but V-12-engined Hawker Fury development proved superior and only one F.20/27 was built.

The Hawker Fury is a British biplane fighter aircraft used by the Royal Air Force in the 1930s. It was a fast, agile aircraft, and the first interceptor in RAF service capable of speed higher than 200 mph in level flight. It was the fighter counterpart to the Hawker Hart light bomber.
