Introduction

日本陸軍が開発した陸戦用の迫撃砲の艦載型改良型です。十分な対潜装備のなかった船舶に装備され、前方投射型の対潜火器としても運用された同迫撃砲をさらに強化改良、これを集中配備した代替対潜火器装備です。同兵装をさらに集中運用、大量の迫撃砲弾の連続発射による対地制圧攻撃も可能です。

An improved shipborne model of the mortar was developed by the Imperial Japanese Army for land warfare. This is the concentrated deployment of the improvised anti-submarine equipment. These upgraded mortars were mounted forwards on ships that did not have sufficient anti-submarine equipment. Further concentrated deployment also allows these mortars to be used for ground suppression by firing multiple large salvos.

Notes

As an ASW Mortar, provides some damage bonus against Installations.

ASW Damage Modifiers: [math]\displaystyle{ \text{Mod}_\text{synergy} = {Mod}_\text{1} \times {Mod}_\text{2} }[/math]
[math]\displaystyle{ {Mod}_\text{1} }[/math]	+ (Any Sonar + Any Depth Charge)	1.15
[math]\displaystyle{ {Mod}_\text{2} }[/math]	DCP + DCR and NO Small	1.1
	Small + DCP + DCR	1.25
Examples
[math]\displaystyle{ \text{Mod}_\text{synergy} }[/math]	Small + DCP + DCR	1.4375[math]\displaystyle{ 1.15 \times 1.25 }[/math]
	Large + DCP + DCR	1.265[math]\displaystyle{ 1.15 \times 1.1 }[/math]
Armor Penetration
Indepentant of synergies, some equipment provides additional armor penetration to ASW attacks. The affected equipment are: DCR: Type 95 DC, Type 2 DC, Lightweight ASW Torpedo, Hedgehog, Type 2 DC K2 DCP: RUR-4A Weapon Alpha Kai, Mk.32 ASW Torpedo (Mk.2 Thrower). The flat armor penetration value is calculated as follows: [math]\displaystyle{ \text{Pen} = \sum\limits_{\text{Equipment}} \Big( \sqrt{\text{ASW}_\text{Equipment} - 2} + \text{Mod}_\text{ship} \Big) }[/math] With [math]\displaystyle{ \text{ASW}_\text{Equipment} }[/math] the base ASW stat of the applicable equipment, Visible Bonuses and Improvements are not counted here. [math]\displaystyle{ \text{Mod}_\text{ship} }[/math] being 1 for DE, 0 otherwise, Note Armor penetration from equipment stacks, The final armor of the targetted submarine cannot go below 1.
