YS-11A-200

The YS‑11A‑200, developed by Nihon Aircraft Manufacturing Corporation in the early 1960s, represents Japan’s first successful foray into modern turboprop airliners after World War II. Originating from a joint venture with the United States’ Lockheed and Douglas, the YS‑11 series was designed to replace aging piston‑engine transports and to serve regional routes across Asia. The A‑200 variant introduced a refined airframe, upgraded AlliedSignal Garrett TPE331‑12U turboprop engines delivering 1,800 shp each, and an extended wingspan that improved lift and fuel efficiency. Its pressurised cabin could accommodate up to 64 passengers, while the reinforced landing gear allowed operations from short, unpaved runways, making it ideal for remote islands and mountainous regions. Avionics were modernised with VHF navigation, autopilot, and weather‑radar systems, enhancing safety and operational flexibility. Though production ceased in the late 1970s, the YS‑11A‑200 left a lasting imprint on Japanese aviation by demonstrating indigenous design capability and fostering a skilled aerospace workforce. Many aircraft remain in service with cargo operators and preservation groups, underscoring the model’s durability and its role as a bridge between early post‑war aviation and contemporary regional transport.
