NAMC designed a low-winged twin- turboprop -engined monoplane , capable of seating up to 60 passengers, dubbed the YS-11 . Amongst the design team was Jiro Horikoshi , who had previously been the designer of the famed wartime Mitsubishi A6M Zero fighter. Another prominent engineer on the project was Teruo Tojo, the second son of Prime Minister Hideki Tojo , who later became chairman of Mitsubishi Motors . The twin-engined YS-11 was projected as delivering similar operational performance to the four-engined British-built Vickers Viscount , while possessing 50% greater capacity than the similarly configured Dutch-built Fokker F27 Friendship . MITI supervised the pricing of the aircraft in order to ensure that it was competitive with the American-built Martin 4-0-4 .^[source]NAMC YS-11 · Development and design / Origins; only the objects and conditions stated in this passage

Although the tentative aircraft was mainly designed and manufactured in Japan, the engine selected to power the airliner was the 2,275 kW (3,050 ehp) Rolls-Royce Dart RDa.10/1 powerplant, which was both developed and produced by British-based company Rolls-Royce . Furthermore, according to author Stephen C Mercado, due to the lack of available domestic technology at the time, several of the key aircraft systems, such as cabin pressurization , were copied from foreign sources; such information was gleaned from a combination of Japanese airlines, trading companies and diplomats. Throughout the YS-11's production lifetime, its electronic equipment, avionics, mechanical and fuselage components were supplied by a combination of Japanese companies and foreign suppliers.^[source]NAMC YS-11 · Development and design / Origins; only the objects and conditions stated in this passage

In 2007, the YS-11 was added to the Mechanical Engineering Heritage of Japan as item number 13. As of 2014 , fifteen were operated by the Japanese military, and two in Mexico. As of 2017 , only eight remained in service with the Japan Air Self-Defense Force , which were being used for flight checks and other ancillary purposes. As of August 2020 , two aircraft remain in commercial service in South America and Africa. As of March 2021 , the Japan Air Self-Defense Force retired the YS-11 after 57 years of service.^[source]NAMC YS-11 · Operational history / End of production; only the objects and conditions stated in this passage
