The Typhoon was originally designed to mount twelve .303 inch (7.7 mm) Browning machine guns and be powered by the latest 2,000 hp engines. Its service introduction in mid-1941 was plagued with problems and for several months the aircraft faced a doubtful future. When the "Luftwaffe" brought the formidable Focke-Wulf Fw 190 into service in 1941, the Typhoon was the only RAF fighter capable of catching it at low altitudes; as a result it secured a new role as a low-altitude interceptor.
