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.
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the T-1B version (prototype aircraft).The T-1Bs remained in service until 3 March 2006, when the last T-1 aircraft was withdrawn from service.

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.

A gorgeous aircraft that would be perfect for 8.3 +1!

I’d say with the Sea Hawk already having AIM-9Bs at 8.0 it is very much possible for T-1 to be placed at an appropriate BR with full armament.

But no matter where it ends up, +1 for one of my all time favorite Japanese aircraft


I like this and would love to have the other trainers to be added to WT but as it stands, this will be controversial since it was never seen with any armaments attached.

I guess the brochure does give leeway to the T-1 but I dont think it would be the same for the others. At the same time, WT is a game - the addition of the trainers will not be as problematic as WT adding the F-16AJ

Failed to unearth any pictures of the T-1 with armament, if they ever carried them they were kept well hidden.

HOWEVER, perusing a thread on the T-1 design origins including all 3 proposals for the competition I discovered a handy post that might swing the balance in the planes favour…

Halfway down are pages from an official English language brochure for the Fuji Heavy Industries T1F2 aka 2nd & 3rd prototypes of the Fuji T-1 and what is included in the drawings…missiles, rockets, bombs, napalm!
