Armaments
Offensive armament
The Ki-108 Kai is armed with:
- 1 x 37 mm Ho-204 cannon, nose-mounted (35 rpg)
- 2 x 20 mm Ho-5 cannons, chin-mounted (200 rpg = 400 total)
Usage in battles
The Ki-108's assets are its excellent guns (especially the 37 mm Ho-204 with its quick rate of fire; the 20mm are unimpressive but will give you a chance to finish a wounded enemy), its climbing speed, and its fairly good manoeuvrability for a plane with so much firepower. Its main weakness is its engine vulnerability. Use the climb rate and speed to engage bombers from the front or front-side, down or cripple, disengage to reload, climb back and repeat. Do not engage bombers from behind as even a B-18A or B-34 has a good chance of crippling you with its tail gunners. Fighters climbing towards you are reasonably easy prey, but try to avoid confrontations where you do not have an altitude advantage, as your dogfighting ability is low and your escape speed is unimpressive if you don't start with a strong advantage.
In Air AB, it's best to side climb, as even when fully upgraded, the Ki-108 will not outclimb aircraft such as the Bf-109 F-4. The Ki-108 performs best when there are teammates above you to provide you with cover - if you find yourself alone at high altitude against single-engine enemy fighters, you'll have to be very wary of them and take them out when they least expect it - a Ki-108 probably won't beat something like a Bf-109 F-4 in a 1 v 1 engagement unless it comes in with an element of surprise or a significant altitude or speed advantage.
Overall, a fantastic interceptor at its battle rating, good enough to regularly score Survivor awards.

Pros and cons
Pros:
- Powerful armaments

Cons:
- Serious overheating issues even without WEP
- The 37 mm are inaccurate even once upgraded
- Low ammo counts; require trigger discipline
- Poor roll rates at low and high speeds
- Highly flammable
History
Development of the Ki-108 began in April 1943 after Kawasaki wanted to fulfil a standing requirement with the Japanese Army for a heavy interceptor that initially began with the Ki-45 heavy fighter series. The Ki-108's design was derived mostly from the previous Ki-102 project and took some elements of the Ki-96 as well, effectively combining the two designs into one. After the first B-29 Superfortress bombers made their appearance over the Japanese home islands, the need for such a high-altitude interceptor became even more emphasized. Two Ki-102 otsu airframes were taken from the assembly line in 1944 to produce the initial Ki-108 prototypes. Compared to the Ki-102, which was intended as a low-altitude attack aircraft, the Ki-108 was an interceptor meant for high altitude operations. To allow for this, the Ki-108's cockpit had to be significantly reduced in size and was to be hermetically sealed. This effectively turned the Ki-108 into a single-seater, reduced weight and decreased the strain on the engines all at the same time, which allowed for better performance at higher altitudes.
The two initial prototypes were completed in July and August 1944, respectively. An improved version of the Ki-108 was designed based around the Ki-102 Hei, featuring a wider wingspan and a longer fuselage, in an effort to improve high-altitude handling. Two examples of the Ki-108 Kai variant were built and subsequently tested in 1945. However, the worsening war situation for Japan prematurely concluded testing of the type and both versions never left prototype stage, yet alone seeing combat. A total of four Ki-108s were manufactured between 1944 - 1945.
