Description

The 37 mm Type 11 pattern 1922 is a Japanese medium-calibre infantry gun adopted for naval use, one of the first slow-firing Japanese weapons that the player will use while going through the research tree. Its effectiveness is average at best, however its explosive power is capable of piercing through nearly anything it might encounter.

Comparison with analogues

The Type 11 comes with the best explosive filler of a comparable cannons, however at the same time it's above average targetting speed and one of the lowest rates of fire. Note that the table below is meant only as an overview, not a detailed analysis.

Usage in battles

Due to the weapon's low targetting speed, combined with an extremely low muzzle velocity it's very difficult to use at range of above 1,000 m, forcing to close in in order to accurately inflict damage. The weapon's strength lies in its explosive filler, able to handle most small boats within few shots.

Pros and cons

Pros:

  • Effective against small, cramped vessels
  • Very high maximum range for its battle rating
  • High firing angle makes it possible to shoot while from behind a complete cover

Cons:

  • Low muzzle velocity makes it difficult to lead targets

History

The 37 mm Type 11 (37 mm狙撃砲, 37 mm sniper) was designed as an infantry gun with the objective of destroying enemy machine gun emplacements. Serial production began in 1918 and the gun saw a number of improvements and evolutions over the years, including pattern 22 (十一年式平射歩兵砲, 11th year model low trajectory infantry gun) until it was finally replaced in 1934 by the Type 94 of the same calibre. The weapon was originally derived from the French Canon d'Infanterie de 37 modèle 1916 TRP.

The gun saw wide use in Japanese forces, from being an infantry support gun, through use in tanks (e.g. Chi-Ro), to the first Japanese armoured boat (with subsequent designs using the 57 mm Type 97 cannon instead). While the gun was up to the task during the Second Sino-Japanese War, it was severely lacking by the time of the Pacific War and unable to penetrate >30 mm armour on allied armoured vehicles even from as close a distance as 50 m.

The weapon featured a wide range of ammunition, including various types of high-explosive rounds with different fillers, armour-piercing, anti-concrete rounds, and of course training rounds.
