Introduction

新開発の高温高圧缶です。
従来の艦本式ロ号缶から換装するもので、駆逐艦「島風」で採用した高温高圧缶をベースに、実用性と量産性を高めたもの。
高出力と低燃費を実現し、回避率を大きく向上させます。
また、改良型タービンとの併用でさらに高い推進力を実現します。

A newly developed high-temperature and high-pressure steam boiler.
Based off of the superheated high pressure boiler used in Shimakaze, but improved for mass production and usability, it replaces the previous conventional Kampon type boiler.
With higher power and reduced fuel consumption, it greatly improves evasion.
Combine it with an Improved Steam Turbine for even higher speed.

Notes

• Enables the engine synergy when equipped together with Improved Kanhon Type Turbine, allowing to upgrade Slow ships to Fast, Fast+, or Fastest, and Fast ships to Fast+ or Fastest. See the following tables for details.
