NAMC YS-11

what is it?

The NAMC YS-11 is a turboprop airliner designed and built by the Nihon Aircraft Manufacturing Corporation (NAMC), a Japanese consortium. It was the only post-war airliner to be wholly designed and manufactured in Japan until the development of the ultimately cancelled Mitsubishi SpaceJet during the 2010s, roughly 50 years later. Development of the YS-11 can be largely attributed to Japan's Ministry of International Trade and Industry (MITI), which had encouraged Japanese aircraft companies to collaborate on the development of a short-haul airliner as early as 1954.
