Japan’s government gathered the designer of the Zero and six rival firms to build one airliner, the YS-11; it carried the 1964 Olympic flame and served for 57 years, but sank its maker under debt.

その物語

NAMC: the company and the aircraft that made its name

A national airliner

In the mid-1950s Japan’s Ministry of International Trade and Industry wanted a home-built airliner to replace the DC-3s on domestic routes, and a way to revive an aircraft industry flattened by defeat. In 1957 Mitsubishi, Kawasaki, Fuji, Shin Meiwa, Showa and Japan Aircraft Industry formed a joint venture, formalised in 1959 as NAMC. The state held 54 per cent. NAMC was essentially a paper company, relying on the staff and factories of its members.

The Zero’s designer and the Olympic torch

Among the designers was Jiro Horikoshi, creator of the wartime Mitsubishi Zero; another was Teruo Tojo, son of the wartime prime minister. Their YS-11, a 60-seat twin turboprop with Rolls-Royce Darts, first flew from Nagoya on 30 August 1962. All Nippon Airways used one to carry the Olympic torch before the 1964 Tokyo Games, and deliveries began on 30 March 1965. Piedmont Airlines in the United States became the biggest foreign customer, with 21.

182 aircraft and a mountain of debt

Commercially it was a failure. Prices were set to undercut rivals rather than cover costs, NAMC had no airline salesmen, and the yen’s rise after 1971 finished any hope of breaking even. Production stopped at 182, the last delivered on 11 May 1973, with debts of about $600 million. NAMC was dissolved on 23 March 1983, yet its airliner outlived it: the Japan Air Self-Defense Force retired its last YS-11 in March 2021, 57 years after the type entered service.

質疑応答

Everything people ask about NAMC

What was NAMC?
The Nihon Aircraft Manufacturing Corporation, a government-backed consortium of Japanese manufacturers formed to build the YS-11 airliner.
How many YS-11s were built?
182, between 1962 and 1973.
Who designed the YS-11?
A NAMC team that included Jiro Horikoshi, designer of the wartime Zero fighter.
Why was the YS-11 a commercial failure?
It was sold below cost, NAMC lacked airline sales experience, and the yen’s rise after 1971 ended any chance of breaking even; the programme ran up about $600 million in debt.
What does YS stand for?
The first sounds of the Japanese words yusō (transport) and sekkei (design).
