Improving Ship Speed

By equipping a Turbine and an Boiler it's possible to make fast destroyers like Shimakaze go speeds far beyond fast. As shown here, using a Improved Kanhon Type Turbine and a New Model High Temperature High Pressure Boiler will result in Shimakaze going to Fastest

By equipping a Turbine and an Boiler it's possible to make Battleship like Yamato go from slow to fast. As shown here, using a Improved Kanhon Type Turbine (shown in the expansion slot) and an Enhanced Kanhon Type Boiler will result in Yamato going to Fast allowing her access to path branching she would otherwise not have access to when she was Slow.

Speed represents the speed of a ship girl. Ship girls are either slow (低速) or fast (高速) by default. As of the 10 Jan 2017 Update, ship girl speed can be further increased to fast+ (高速+) or fastest (最速) by using a combination of Engine Improvements: a Turbine with one or more Boilers
.

Overview

There are several effects of increasing ship girl speed:

• Meeting routing requirements.
  • Slow ships can be sped up to fulfil certain branching requirements.
    • Note that this does not apply to ship type requirements. Eg a BB will not count as a FBB where FBBs are specifically required.
  • Fast+ and fastest are required to fulfil routing requirements in some maps. Eg. 3-2 and 4-5.
• Combined Fleet composition.
  • Slow battleships that are fast+ can be placed in the escort fleet.
• Evasion increase.
  • Although this has been stated by the developers to occur, testing has not shown any significant increase in evasion.
• Because Coastal Defense Ships cannot equip Engine Improvements, they are the only ship type that cannot be sped up.

Speed Change Charts

It is highly recommended that you have a Reinforcement Expansion on ship girls that you wish to speed up. It can severely degrade their combat efficiency if you attempt to speed up ship girls without one.

• Enhanced Kanhon Type Boiler = +10 Boiler
• New Model High Temperature High Pressure Boiler = +13 Boiler

All synergies listed below already include 1 Improved Kanhon Type Turbine because it is an absolute requirement for speed ups.
