Combat/Anti-Installation

Introduction

Installations are an enemy type in game that is characterised by high armour and high HP. They are difficult to handle using normal anti-ship setups and require specific setups in order to destroy. Installations are typically found as bosses or as boss escorts.

General Characteristics

• They cannot be targeted by torpedoes.
  • Opening and closing torpedoes will fail to trigger if only installation targets remain.
• The torpedo stat is ignored when calculating night battle damage against installations. Please see Night Battle for more details.
  • This makes destroyers, light cruisers and heavy cruisers much weaker unless equipped with anti-installation equipment.
• Submarines can attack installations during shelling if equipped with a Type 2 Ka-Mi Tank.
  • They will be able to attack installations at night regardless of equipment.
  • Their low firepower makes them poor anti-installation ships.
• Only dive bombers will attack installations during the air strike phase.
• Carriers will only attack installations in the shelling phase if equipped with torpedo bombers or anti-installation dive bombers.
  • The special dive bombers are:
    • Ju 87C Kai
    • Ju 87C Kai Ni (w/ KMX)
    • Ju 87 C Kai 2 (w/ KMX / Skilled)
    • Prototype Nanzan
    • Suisei Model 12 (634 Air Group w/ Type 3 Cluster Bombs)
    • FM-2
    • F4U-1D
  • Any other dive bomber will completely disable shelling against installations even if the carrier has a torpedo bomber equipped.
  • This can be very useful to manipulate the targeting mechanic so the carriers attack important targets.
• Carriers are unable to perform cut-ins on installations, even if equipped with anti-installation dive bombers.
• They have different damage statuses instead of the normal ones used for ships.

Installation Classification

Installations are classified by two categories, Ship Type (BB, BBV, CV) and skin toughness (Hard, Soft).

Ship Type

Battleship (BB)

• Examples are Artillery Imps and Central Princess.
• They use the surface shelling formula for calculating damage.
• They use the shelling attack animation in day and night battle.
• They can continue attacking when moderately damaged.

Aviation Battleship (BBV)

• Most installations fall under this category.
• They use the carrier attack formula for calculating damage.
• They use the shelling attack animation in day and night battle.
• They cannot attack during the day if heavily damaged.
• They are forced to attack submarines if they have equipment with an ASW stat.

Carrier (CV)

• Example is Lycoris Princess.
• They use the carrier attack formula for calculating damage.
• They use the carrier attack animation in day battle and the shelling animation at night.
• They cannot attack during the day if moderately damaged.
• They do not enable the 2nd shelling phase if there is no battleship present.
