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 either from before or after World War II. 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.
