The Project 123K "Komsomolets" is a rank I Soviet motor torpedo boat with a battle rating of 2.0 (AB/RB/SB). It was introduced during Update 1.79 "Project X" when the Soviet fleet was implemented into the game.

General info

Survivability and armour

The Pr.123K, like the majority of vessels at rank I, has no armour. As this is a boat of the same class as its predecessor in-game (Pr. 123bis), it has the same vulnerabilities - easily destroyed engines and frequent fires.


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

The Pr. 123K has half the number of machine guns than Pr. 123bis, but they have a larger caliber (dual 14.5 mm KPV machine guns). Generally, this is a disadvantage at this battle rating, because the vast majority of boats you will face will have no armour. The machine guns are mounted at the stern of the boat, behind the bridge. That means that you are unable to shoot enemies right in-front.

Unfortunately, to target any enemies you have to show your side. This is not ideal, because at battle rating 2.0 enemies will have sufficient firepower to destroy your ship in seconds.

Torpedo armament

The Pr. 123K is equipped with 2 450 mm wet-heating 45-36NU torpedoes, which are placed on the sides of the boat. When released, they are fired forwards already at speed, which allows you to get a jump on any opponents who are in the torpedo range. It is a good idea to rush tougher opponents and fire your torpedoes very close to them to guarantee a hit (use this tactic at higher battle ratings to get rid of the toughest ships).

Special armament

The Pr. 123K can carry 4 BB-1 depth charges, which can be used as time-based mines or as traps for opponents who are circling you. It is advised to read the full BB-1 article which covers its uses in more depth.

Usage in battles

The Pr. 123K has only two machine guns, which are dual-mounted, but they have a larger caliber (14.5 mm) than its predecessor. Moreover, it gets two torpedoes, which are fired forwards at speed (can be an advantage, but also a disadvantage). All of that weaponry is placed on a motor boat which can reach very high speeds. It's a boat that will help you grind out USSR rank I fleet.

After playing the Pr. 123bis, this boat will seem to have much less firepower. It is also problematic that you have to expose your side to engage any opponents, because your machine guns are placed behind the bridge. This boat is harder to use, but it can encounter opponents at battle rating 3.0, some of which you cannot penetrate. You have to play very carefully, and always stay at speed, or you will get picked of very quickly by gun boats with large guns. You should be the person to capture points for your team, and stay a nuisance for the enemies.

Pros and cons


  • Can reach very high speeds, which makes flanking easy and makes it harder to hit the boat.
  • Has 2 torpedoes which are guaranteed to sink opponents on impact.


  • No armour.
  • No anti-air armament.
  • Inability to engage opponents right in-front.


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 big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.


An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
