Introduction

改良型の新型タービン機関です。
従来型タービンの各部素材を見直し構造強化を行なって、より高出力が可能となりました。
機動性が向上し、砲雷撃戦や、対空戦における回避率が向上します。

This is the improved version of the steam turbine engine.
The existing turbine's parts and materials have been revised for this new construction, making higher outputs possible.
This allows for even more evasion from torpedo attacks and air strikes.

Notes

• Equipping this item in combination with one or more boilers (Enhanced Kanhon Type Boiler and New Model High Temperature High Pressure Boiler) on a ship will upgrade their speed: Slow ships will upgrade to Fast, Fast+, or Fastest, while Fast ships will upgrade to Fast+ or Fastest, see the following tables for details.
