Fuji T-1B Hatsutaka (富士 T-1B 初鷹)
The Fuji T-1B is a Japanese upgrade of the Fuji T-1A aircraft. It replaced the engine from British to Japanese. 20 copies of this version were made.
History
From the very beginning, JASDF wanted to equip the T-1 aircraft with Japanese-made engines, but the work on the Ishikawajima-Harima J3 engines was delayed, so it was decided to install British Bristol Siddeley Orpheus Mk 805 engines. Although the first prototypes of the J3 engine were ready in 1957, there were many problems related to it, so the Japanese had to refine it, which took almost 3 years.As a result, the first two production series (40 T-1 aircraft) and 6 prototypes were equipped with British engines. At the very beginning, the production of the J3 engine was carried out by 5 different companies (Ishikawajima Heavy Industries (now IHI), Fuji Heavy Industries, Fuji Seimitsu Industries, Mitsubishi Heavy Industries and Kawasaki Heavy Industries), but at the behest of the JASDF headquarters, it was recommended that the production be carried out by one company, so that all engines would have the same technical control.After lengthy negotiations between the companies, it was decided that Ishikawajima Heavy Industries (IHI) would be the engine manufacturer. With this change, IHI was able to contribute to the improvement of the prototype J3 engine. By July 1959, the improved engine was ready for testing, which it successfully passed. In 1960 it was mounted on the T-1 aircraft with number 05-5801 and practical tests were carried out on the mime.Engines for the J3 was accepted into service in 1961 under the name J3-3. The T-1 aircraft were equipped with these engines in the third production series and received the designation T-1B (aircraft from 851 to 870). They were produced from September 1962 to June 1963, in addition to 2 T-1A aircraft were converted to the T-1B version (prototype aircraft).The T-1Bs remained in service until 3 March 2006, when the last T-1 aircraft was withdrawn from service.
Structure description
The T-1B aircraft was fitted with Ishikawajima-Harima J3-3 engines with a power of 11.77 kN. Other than that, no modifications were made to the aircraft.

Summary
The Fuji T-1B trainer would be a very nice addition to the Japanese aviation tree. Although it has two AIM-9 missiles, which classifies it as around 9.0 this year, it is better to have them without them in the game, which will allow this aircraft to be used more effectively at lower BRs as a CAS aircraft. Along with its T-1A and T-1C brethren, it would be a great complement to the early Japanese jets. I encourage you to discuss in the comments and to share your own knowledge on this topic.
Finally, I apologize for the linguistic and logical errors because unfortunately English is not my main language and I had to use google translator.
