Notes

Ship girl speed can be further increased to Fast, Fast+, or Fastest by using a combination of Improved Kanhon Type Turbine, Enhanced Kanhon Type Boiler or New Model High Temperature High Pressure Boiler. See the following tables for details.

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