I-Go-1A Anti-Ship Missile on Trailer Fussa 1944
Mitsubishi Ki-147
With the addition of the Ki-148, the Ki-147 missile, which is a more powerful missile from Mitsubishi, should appear. Here is a suggestion about this very interesting rocket.
Japan has been researching remotely guided weapons since the 1930s. Already at the end of 1938 it was possible to test a remote-controlled glider. Work on the future I-Gо̄ missiles began in 1942 with the assumption that they would be used to sink ships without exposing themselves to anti-aircraft fire.Rocket development was split between Mitsubishi (I-Gō Model 1 Kо̄), Kawasaki (I-Gō Model 1 Otsu) and the University of Tokyo (I-Gō Model 1 Hei). The companies were supposed to take care of everything except the control systems, which were to be handled by the University of Tokyo. Mitsubishi was to create a heavy version of the rocket with an 800kg warhead. Research and development continued until May 1944, when the military realized the futility of the Kamikaze and increased its efforts for I-Gō rockets.Thanks to increased funding for the project and previous research, the first prototype was ready in October. At that time, tests began on this rocket without propulsion and showed a lot of problems with the autopilot systems. The carrier aircraft was the Ki-67, which underwent minor modifications. 10 test rockets were produced, but due to raw material shortages and the defeat in Leyte Gulf, the project was halted in favor of the lighter Ki-148 missile.

Comparison of Ki-147 and Ki-148


Structure description
The airframe design has been greatly simplified for one-off use. It was a high-wing aircraft with a straight wooden wing, and the fuselage was manufactured by stretching corrugated sheets on a round metal frame. The main wing is near the front of the fuselage, and the vertical stabilizer and injection nozzle are located at the rear and tail of the fuselage, which is the same as the Ki-148, but the difference is that there is a cylinder above the main wing and the main wing has a slight oblique angle.The guidance system is a manual command-line matching guidance system, and a Tokoro No. 1 Type 3 liquid-propellant rocket is used for power. The engine used hydrogen peroxide as fuel and sodium permanganate as a catalyst. These two chemicals were pumped into the combustion chamber using compressed air and a thrust of 240 kgf was generated for 75 seconds.

This racket, due to its performance, weight and strength, should be very interesting and rare things added to War Thunder. Its weight allows it to be carried by the Ki-67 and G8N1, but the G5N1 cannot be classified as one of these aircraft due to the fact that in 1944 it was only a transport aircraft. Although the possibility of mounting on the G8N1 has never been officially mentioned, it was created at the right time and has the appropriate lifting capacity.In addition, Gaijin can and does do do whatever he wants (adding the F-16AJ and the Yak-141 armament), so I suggest that this missile go to Raizen as well. The mode of operation of this missile is like the Ki-148 and would be easy to balance.This would enable Japan to have a precise CAS of 4.7 and 6.0, which is very much needed for it. In addition, I’m a fan of Japanese technology, of which in some places they were precursors (I-400, Yamato, Ka-tsu) or were very interesting (GCS-1, KI-148, Ki-147, OI, Ke-Go, AAM-1, AAM-2,Ki-91,Ki-98).I encourage you to discuss in the comments.
Finally, I apologize for the linguistic and logical errors because unfortunately English is not my main language and I had to use google translator.

+1. How do you feel about the ohka, do you think it could be possible to implement?

At the moment, there is no carrier aircraft for the Ohki because it was carried by the G4M2e Model 24 Tei, which would be at the H8K2 level by War Thunder standards. But it would be nice to have such a powerful “rocket” from the Japanese.
