The PT-15, Type 11 is a rank II Japanese motor torpedo boat with a battle rating of 3.3 (AB/RB/SB). It was introduced in Update 1.89 "Imperial Navy".

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 armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical 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 and reverse speed.


Primary armament

Each Bofors gun is placed on front and back of boat. This mean that both of them have large natural blind spot. These are most effective when being used against small craft such as torpedo boats, motor gunboats, minesweepers and submarine chasers. In its BR class, it is possible to face larger threats including destroyers which will mostly be unharmed by this gunfire. Aircraft are also excellent targets and can be brought down with accurate fire. You can load Universal belt, HE belt or AP belt. Usage of these belts is similar to lower rank boats; Universal is good for start but later you should stick to HE or AP by what kind of target you encounter. The downside of the primary armament is that they can easily overheat if you fire for too long.

Torpedo armament

Main article: Mk.16 (533 mm)

This ship is armed with four Mk.16 torpedoes on its side. They are offset at a slight angle so you can't release all four of them at once on one target. The Mk.16 torpedo has a good speed of 85 km/h and 6.4 km range should be enough for close and mid-range combat between islands. The true advantage of the Mk.16 is 915 kg of TNT which is second highest in game and highest used on torpedo boats.

Usage in battles

Usage of this boat is similar to Type T-38. You have very capable armament against other boats but that's about it. Type 11 is fairly big compared to other boats and mobility isn't its strong suit either. A good way to engage opponents is to stay back and use your fairly powerful armament against them, though the weapon placement means that if you want to use your maximum firepower you have to show your full profile to enemy. Try to look for islands and corridors where you will be hidden from high calibre long range cannons and ships with heavy armament that are common at this rank. You should not even try to engage bigger ships with cannons in open waters as they will notice you due to your size and can give you critical or fatal damage with a single shot. Using torpedoes is very situational; the only way to use them is to sneak around islands and attempt to surprise unwary destroyers.

In anti-aircraft role you have to rely on yourself as this boat doesn't have any secondary or AA armament. Although Bofors guns can be very effective against airplanes you should focus on ships which are a bigger threat for you.

Pros and cons


  • Primary armament can be effective with skilful use
  • 4 torpedoes with excellent explosive mass


  • No secondary or AA weapons
  • Very vulnerable, easy to be one-shot by high calibre guns
  • Relatively big size compared to other torpedo boats
  • When using both Bofors guns, the boat will expose its large profile to the enemy


Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).


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