Description
The Ho-203 37 mm is a Japanese, early-rank cannon found on the Ki-45 (Family) of twin-engine fighters. It is a fast-firing, high-damage cannon that has the ability to one-shot many heavily armed planes. It is always paired with two fast-firing 20 mm Ho-5 cannons that allow you to preserve ammo by alternating which guns you use. They typically have a low ammo count but have a much higher fire rate than other 37 mm cannons, meaning trigger discipline is of the utmost importance. The low BR in which this cannon is found is a blessing in disguise because your opposition is generally moving at very low speeds, allowing you proper time to lead your shots.
The main downsides of the cannon are its low muzzle velocity and its inability to carry AP ammo. This severely limits its effectiveness in Ground RB, because you will be unable to get through any armor with this cannon. The low muzzle velocity makes it difficult to target small, nimble fighters.

General info
The cannon is a very fast-firing cannon in terms of its caliber, but it is still nothing compared to the fire rate of 20 mm cannons. It shines in the bomber-interception role, where it can be used to target large bombers. It usually takes a single hit to cripple a bomber or destroy it.

Comparison with analogues
The cannon is regarded as one of the fastest firing 37 mms when compared with other nations. However, it has a lower muzzle velocity and no access to AP ammo.
- ▀ BK 3.7: Germany's only 37 mm cannon is probably the best 37 mm cannon of the war. Although it has a lower fire rate, the cannon is deadly accurate, has a ridiculous muzzle velocity, great penetration on AP shells, and much more ammo than its counterparts when mounted in the belly.
- ▃ M4/M10: America's 37 mm found in the Kingcobra/Airacobra family of aircraft, as well as a few others. It has very poor accuracy and only half the fire rate of the Ho-203. It suffers from poor belt selection, and its AP rounds do not have much penetrating power. Its ammo count is what gives it a slight advantage when compared to the Ho-203

- ▅ Type 94: Currently the only cannon in the game that is used in both a tank and a plane, the Type-94 was the first anti-tank cannon that Japan built.

Currently, the cannon is found on the Ki-45 otsu variant, as well as the Ha-Go and Ro-Go series of tanks. It is a very poor choice of aircraft cannon.
Usage in battles
Boasting an incredible fire rate and good explosive filler, the Ho-203 cannon shines in hitting large, slow targets like bombers. It is usually a one-hit kill and requires skill to lead your shots due to its low muzzle velocity. It is found on interceptor aircraft and is mounted in the nose of most planes, making it easier to hit the designated target.
Pros and cons
Pros:
- Very fast fire rate for a 37 mm cannon
- Good explosive filler
- Mounted in the nose
- Will not jam quickly when upgraded
- Fairly accurate
Cons:
- Poor muzzle velocity
- No access to AP rounds
- Very limited ammo
History
The story of the Ho-203 begins in World War I with the French Canon d'Infanterie de 37 modèle 1916 TRP which was designed as a man-portable weapon for destroying machine gun nests. After the war ended, Japan began licensing multiple designs from France including the Modéle 1916 TRP which became the Type 11 pattern 1922 (37 mm) Infantry Support Gun, which has a vertically sliding breech block and steel tube frame that replaces the original wheeled carriage. The Ho-203 is a variant of the Type 11 adapted for a long recoil action enabling automatic fire at a rate of 120 rounds per minute at a muzzle velocity of 1,900f/s (570m/s) and an effective range of 3,000 feet (900 meters). The Ho-203 is fed with a 15-round drum magazine and mounted as a bomber killer weapon for the Ki-45-KAI and in a Schräge Musik mount on Ki-46 for use as heavy fighters.
