General info

Survivability and armour

Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armament separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips for preserving survivability in the "Use in battle" section.

If necessary, use a graphics template to show the most well-protected or most vulnerable points in the armour.


Write about the ship’s mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward speed and reverse speed.


Primary armament

Main article: Type 97 (57 mm)

Provide information about the characteristics of the primary armament. Evaluate their efficacy in battle based on their reload speed, ballistics and the capacity of their shells. Add a link to the main article about the weapon: {{main|Weapon name (calibre)}}.

Broadly describe the ammunition available for the primary armament, and provide recommendations on how to use it and which ammunition to choose.

Secondary armament

Main article: Type 98 (20 mm)

Some ships are fitted with weapons of various calibres. The secondary armament is defined as the weapon chosen with the control Select secondary weapon. Evaluate the secondary armament and give advice on how to use them. Describe the ammunition available for the secondary armament. Provide recommendations on how to use them and which ammunition to choose. Remember that anti-air armament, even heavy calibre weapons, belong in the next section.

If there is no secondary armament, remove this section.

Special armament

Main article: Type 95 depth charge

Depth charges, mines, rocket launchers and missiles are also effective in skilled hands and can take an off-guard opponent by surprise. Evaluate the ammunition of this type of armament and rate its performance in combat.

Usage in battles

Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don’t try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons

Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".




Ha-Go Fighting Boat Model 1 (波號戦斗艇一型), also known Se-Ha (せは艇) is a first prototype of Small Escort Boat (小護衛艇). Small Escort Boat was designed for escort "Daihatsu" class landing crafts that transport munitions to offshore islands.

In January 1944, Imperial Japanese Army 10th Technical Research Institute order to Hitachi Zosen Sakurajima shipyard two types of small escort craft. First one called Ha-Go Fighting Boat Model 1 "Se-Ha"(Ha-Go means "Mark A") that equip two 150 hp engine, and second one called Ha-Go Fighting Boat Model 2 "Se-Ni" that equip two 60 hp engine.

Se-Ni completed in October but speed of that boat was only 9 knots so this plan was cancelled. Also Se-Ha completed in December 1944, but by the result of trial engineers decide to modify design to get more speed.

Third design, "Se-Ha Kai" was completed in July 1945. In the trial cruise during October 2 ~ 5, its speed reached to 13 knots so research completed. By the surrender of Japan, it was not adopted formally, but adopted name of Se-Ha Kai will be Type 5 Small Escort Boat. ("Type 5" already in game is Large Escort Boat.)


Excellent additions to the article would be video guides, screenshots from the game, and photos.
