(Question)
Information: - Hawker Aircraft Limited was a British aircraft manufacturer responsible for some of the most famous products in British aviation history. - Squadron Leader Neville Frederick Duke DSO , OBE , DFC & Two Bars , AFC , FRAeS ( 11 January 1922 -- 7 April 2007 ) was a British test pilot and fighter ace of the Second World War . He was the most successful Western Allied ace in the Mediterranean Theatre , and was credited with the destruction of 27 enemy aircraft . After the end of the war , Duke was acknowledged as one of the world 's foremost test pilots . In 1953 , he became holder of the world air speed record when he flew a Hawker Hunter at 727.63 mph ( 1,171.01 km / h ) over Littlehampton . - The Royal Air Force (RAF) is the United Kingdom's aerial warfare force. Formed towards the end of the First World War on 1 April 1918, it is the oldest independent air force in the world. Following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world. Since its formation, the RAF has taken a significant role in British military history, in particular, playing a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. - The Hawker Hunter is a transonic British jet-powered fighter aircraft that was developed by Hawker Aircraft for the Royal Air Force (RAF) during the late 1940s and early 1950s. It was designed to take advantage of the newly-developed Rolls-Royce Avon turbojet engine and the swept wing, and was the first jet-powered aircraft produced by Hawker to be procured by the RAF. On 7 September 1953, the modified first prototype broke the world air speed record for jet-powered aircraft, achieving a speed of . - A swept wing is a wing which angles either backward or, occasionally, forward, from its root rather than in a straight sideways direction. Wing sweep has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore often used on jet aircraft designed to fly at these speeds. Swept wings are also sometimes used for other reasons, such as structural convenience or visibility. - Squadron leader (Sqn Ldr in the RAF and PAF; SQNLDR in the RAAF and RNZAF; formerly sometimes S/L in all services) is a commissioned rank in the Royal Air Force and the air forces of many countries which have historical British influence. It is also sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. - A fighter aircraft is a military aircraft designed primarily for air-to-air combat against other aircraft, as opposed to bombers and attack aircraft, whose main mission is to attack ground targets. The hallmarks of a fighter are its speed, maneuverability, and small size relative to other combat aircraft. - An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. - The Rolls-Royce Avon was the first axial flow jet engine designed and produced by Rolls-Royce. Intended as a jet successor to the Merlin, introduced in 1950 it went on to become one of their most successful post-World War II engine designs. It was used in a wide variety of aircraft, both military and civilian, as well as versions for stationary and maritime power. - A test pilot is an aviator who flies new and modified aircraft in specific maneuvers, known as flight test techniques or FTTs, allowing the results to be measured and the design to be evaluated. Given the information above, choose from the list below the object entity that exhibits the relation 'military branch' with the subject 'neville duke'. Choices: - aircraft - royal air force - squadron
(Answer)
royal air force
