NAMC YS-11
The NAMC YS-11 is a turboprop airliner built by a Japanese consortium, the Nippon Aircraft Manufacturing Corporation. The program was initiated by the Ministry of International Trade and Industry in 1954: the aircraft was rolled out in 1962, and production ceased in 1974. To date, the YS-11 is the only successful commercial aircraft made by a Japanese firm. 182 were produced in total. Although most of the aircraft was designed and manufactured in Japan, the engines were built by Rolls-Royce. The twin-engined YS-11 delivered similar operational performance to the four-engined Vickers Viscount, and had 50% more capacity than the similarly-configured Fokker F.27.
