Miles M.20

During the Battle of Britain, a shortage of fighters was expected. That's why Miles was asked to design a machine that was easy and quick to manufacture and could easily complement the range. Walter Capley at Miles designed a simple machine, which was an all-wood construction, with a fixed chassis, so it did not need complex hydraulics, and instrumentation largely taken over from a classic training machine Miles Master. The engine and its storage was again identical to the engine groups Avra Lancaster and Bristolu Beaufighter. For the first time among British fighters, it also had a teardrop-shaped canopy. The armament consisted of eight machine guns, but with the possibility of building another four. Only 65 days passed from the design to the first takeoff, which took place on September 14, 1940. In the meantime, however, the need for an additional fighter disappeared, so further development was stopped and this prototype was later scrapped at Woodley.
However, Miles used the proposal for specifications N.1/41, issued by the Naval Air Force, which required a simple onboard fighter, which could take off from the so-called CAM ships (Catapult Aircraft Merchantmen), classic merchant ships, which were modified to provide air protection convoys. , but which did not have enough landing area. The aircraft was therefore to take off once, had a disposable landing gear and landed at sea level. This prototype first started on May 8, 1941. But in the end these machines were not needed until the introduction of a new type, it paid off to use the old and actually discarded Hurricans, the second prototype so soon followed its older sibling.
