Arill/Sandbox/Combat/Installations

Introduction

Installations, also known as Land Bases, are a special type of enemy generally reserved to ranks such as Princess and, by extent, possess unusually high combat prowess and durability. Installations are meant to represent military facilities and fortifications such as anchorages and airfields, and thus are difficult to deal with through traditional "anti-ship" means and will most likely require special setups to be defeated.

General Characteristics

All installations follow the following set of rules:

• Only Firepower stat is considered for attacks that target installations. Torpedo stat is treated as 0 for all damage calculations that target installations.
  • Torpedo-based attacks such as Opening and Closing Torpedo Salvos, and Torpedo Bomber Airstrikes cannot target installations.
  • This makes high-torpedo ship classes such as Destroyers and Light Cruisers much weaker when fighting installations, even at night.
• Submarines are able to perform surface shelling against installations during the day, if equipped with at least one Special Type 2 Amphibious Tank.
• Carriers are unable to target installations unless equipped solely with Torpedo Bombers and Anti-installation Dive Bombers.
  • Anti-installation Dive Bombers are the following:
    • Ju 87C Kai
    • Ju 87C Kai Ni (w/ KMX)
    • Ju 87C Kai Ni (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 prevent the Carrier from shelling installations.
• As Torpedo Bombers are not taken into consideration when calculating installation damage, Carriers cannot perform Aircraft Carrier Cut-in (CVCI) against installations.
• Damage statuses are different for installations.
  • Confused (混乱) (Konran, (混乱)^?) for Lightly Damaged.
  • Damaged (損害) (Songai, (損害)^?) for Moderalely Damaged.
  • Broken (損壊) (Sonkai, (損壊)^?) for Heavily Damaged.
  • Destroyed (破壊) (Hakai, (破壊)^?) when Sunk.

Classification

Installations are classified by two categories: Type (BB, BBV, CV) and Toughness (Soft Skin or Hard Skin).

Type

Type	Characteristics
Battleship (BB)	Examples are Artillery Imps and Central Princess. Uses the surface shelling formula for calculating damage. Uses the shelling attack animation in day and night battle. Can continue attacking when moderately damaged.
Aviation Battleship (BBV)	Most installations fall under this category. Uses the carrier attack formula for calculating damage. Uses the shelling attack animation in day and night battle. Cannot attack during the day if heavily damaged or if there are no planes left. Forced to attack submarines if they have equipment with Anti-Submarine stat.
Carrier (CV)	Example is Lycoris Princess. Uses the carrier attack formula for calculating damage. Uses the carrier attack animation in day battle and the shelling animation at night. Cannot attack during the day if moderately damaged or if there are no planes left. Do not enable the 2nd shelling phase if there is no battleship present.

Toughness

Type	Characteristics
Soft Skin	Examples are Supply Depot Princess, Harbour Princess and Northern Princess. Takes a lot of damage from Anti-Aircraft Shells and less from other Anti-Installation equipment. This weakness allows battleships and heavy cruisers to easily deal with these installation types. Still takes a decent amount of damage from other anti-installation equipment. Supply Depot Princess has extra Post-Cap modifiers.
Hard Skin	Examples are Isolated Island Demon, Artillery Imp, and Harbour Summer Princess. Takes more damage from Anti-Installation equipment like Landing Crafts, Amphibious Tanks and Anti-ground Artillery
