T-3

The Subaru T‑3 is a single‑engine, low‑wing primary trainer that entered service in 1979 after a development program that began in 1974 under the auspices of the Japanese Ministry of Defense. Designed and built by Subaru Corporation – better known for its automotive expertise – the T‑3 marked the company’s first full‑scale entry into fixed‑wing aviation. The aircraft combines a tubular steel fuselage with an all‑composite wing structure, providing a lightweight yet robust airframe that tolerates the harsh training environment. Power is supplied by a 210‑horsepower Lycoming IO‑360‑B2A engine driving a two‑bladed constant‑speed propeller, delivering smooth handling and reliable performance at low altitudes. Cockpit ergonomics were emphasized; dual side‑by‑side seats feature fully duplicated flight controls, modern avionics and a glass‑panel display that can be upgraded to simulate advanced fighter systems. Over 150 units were produced, serving the Japan Air Self‑Defense Force, the Korean Air Force and several civilian flight schools. The T‑3’s significance lies in its role as a bridge between piston‑engine trainers and modern jet trainers, proving that a non‑traditional manufacturer could deliver a durable, cost‑effective platform that helped shape pilot training standards throughout Asia.
