Speed {{Speed}} represents the speed of a ship. Ship are either '''slow (低速)''' or '''fast (高速)''' by default. As of the [[Game_Updates/2017/January_10|10 Jan 2017 Update]], ship speed can be further increased to '''fast+ (高速+)''' or '''fastest (最速)''' by using a combination of {{Turbine}} [[Engine Improvement]]s: a {{EquipmentLink|Improved Kanhon Type Turbine|text=Turbine}} with one or more {{EquipmentLink|Enhanced Kanhon Type Boiler|New Model High Temperature High Pressure Boiler|text=Boilers}}.

Ship's speed can take the following values:

* Slow (低速)

* Fast (高速)

* Fast+ (高速+)

* Fastest (最速) (sometimes "Fast ++")

Equipping a Turbine and a Boiler make fast DD like Shimakaze go to speeds beyond fast. Here, using a Turbine and a +13 Boiler results in Fastest speed.
Equipping a Turbine and a Boiler make a BB like Yamato go from slow to fast. Here, using a Turbine (in the RE) and an +10 Boiler results in Fast speed.

Speed Speed represents the speed of a ship. Ship are either slow (低速) or fast (高速) by default. Ship speed can be further increased to fast+ (高速+) or fastest (最速) by using Engine Improvement Engine Improvements, usually a combination of a TurbineImproved Kanhon Type Turbine with one or more BoilersEnhanced Kanhon Type Boiler
New Model High Temperature High Pressure Boiler
.

Overview

Ship's speed can take the following values:

  • Slow (低速)
  • Fast (高速)
  • Fast+ (高速+)
  • Fastest (最速) (sometimes "Fast ++")

There are several effects of increasing ship speed:

  • Meeting routing requirements:
    • Fleet speed affect certain map routing.
      • Note that this does not apply to ship type requirements (e.g. a BB will not count as an FBB where FBBs are specifically required).
      • Most map routings are only affected by slow/fast fleets, fast+ and fastest being required for routing in very few maps (e.g. 3-2 and 4-5).
  • Combined Fleet composition:
  • Evasion increase:
    • Devs claim ([1]) that higher speed values increase evasion, however, no such bonus has ever been measured ([2][3]).
  • Because Coastal Defense Ships (DE) cannot equip Engine Improvement Engine Improvements, they are the only ship type that cannot be speed-up. The only exception is Inagi Kai Ni.

Speed Change Charts

It is highly recommended to have a Reinforcement Expansion on ships that are sped-up. Ships sped up without using a RE will have severely degraded combat efficiency in most cases.

So far, only 2 "boilers" exist in the game, and they are referred to as:

Unless stated otherwise, synergies listed below already include 1 Improved Kanhon Type TurbineImproved Kanhon Type Turbine, as it is a requirement for almost all speed-ups.
