| This page is about the Japanese fighter Ki-44-II otsu. For other versions, see Ki-44 (Family). |
The Ki-44-II otsu Shoki, designated as the Type 2 Single-Seat Fighter, Model IIb (二式単座戦闘機一型乙), was a Model II variant of the Ki-44, featuring an improved engine and nose-mounted 12.7 mm guns. While it was equipped with only its nose armament, it could also be optionally fitted with 40 mm cannons in the wings, although these were sometimes swapped out for 12.7 mm guns due to the 40 mm’s unsatisfactory performance. The 40 mm cannons were specifically intended for countering American bombers, but despite their lethality, the Ki-44 remained an underwhelming aircraft for high-altitude interceptions against the B-29, as the cannons were effective only at very short ranges with limited ammunition—essentially at a ramming distance. This tactic was later formalised by several Army Sentai under the "Shinten Seiku-Tai" (震天制空隊) units, which used standard army planes or those stripped of armour and armament to reduce weight, enabling them to ram bombers out of the sky more efficiently. This approach was akin to the German Sonderkommando "Elbe" 's mission in 1945 and the Russian "Taran" tactics of 1941. Although survival rates were low and the attacks were effectively kamikaze missions, some pilots managed to survive multiple sorties, ramming a bomber and then ejecting to continue fighting another day.
It was introduced in Update 1.55 "Royal Armour". The Ki-44-IIb features one of the slowest-velocity cannons ever mounted on an aircraft, but the 40 mm shells pack a significant punch if they manage to hit—though this is admittedly difficult to achieve. The Ki-44-II is equipped with a powerful engine, enabling the aircraft to reach interceptor altitudes quickly and effortlessly, making it ideal for strafing bombers at high altitudes and destroying them in a single pass. Pilots should reserve their 40 mm ammunition for bombers, focusing on getting close at high speeds, as targeting smaller aircraft with these cannons presents a considerable challenge. Once the 40 mm rounds are depleted, the Ki-44-IIb can still be a formidable boom-and-zoom fighter against other aircraft, with its nose-mounted 12.7 mm machine guns providing decent lethality thanks to their high-explosive rounds.

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.
The Ki-44-II otsu is armed with:
The twin Ho-103 machine guns are identical in performance to most other Japanese aircraft carrying this type. The air targets belt is recommended in most situations as it carries a great balance of armour piercing and incendiary components along with tracer rounds, not to mention high-explosive rounds, which is very unusual for machine guns. The twin Ho-301 autocannons are devastating to anything which it hits, making short work of most aircraft. The unfortunate drawback with these cannons is that they utilise very low-velocity rounds and will need a large lead on anything being attacked, with a larger lead time the further out the target is.
The Ki-44-II otsu can be outfitted with the following ordnance:
Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
