Once the Japanese aircraft industry had been cleared to begin production again in 1953, the government awarded a number of substantial contracts to Fuji with the aim of producing indigenous jet-powered aircraft to replace American-supplied piston-engined T-6 Texans. The company had already constructed a small turbojet engine to power just such an aircraft, hut the first T1F1 was powered by an imported Bristol Siddeley Orpheus engine. The design leant heavily on the North American F-86 Sabre. Designated T-1 A by the JASDF, the Orpheus powered aircraft began to enter service in 1961 and by July of the following year 40 had been delivered. The company also produced a T1-B version, powered, or rather underpowered, by the Japan Jet Engine Co. J3-3. This engine delivered only two-thirds of the thrust of the Bristol engine.
