The '''Pr.123K''' represents an upgraded iteration of the [[Pr.123-bis]] MTB. In 1950, the Soviet Navy required reinforcement of the Pr.123-bis hull due to the transition from American Packard petrol engines to domestic M-50 diesel engines. The original hull structure couldn't withstand the demands imposed by these new engines. Moreover, with the discontinuation of the production of the [[DShK (12.7 mm)|DShK]] 1938 heavy machine gun, the designers opted to replace it with twin 14.5 mm [[KPV (14.5 mm)|KPV]] heavy machine guns. Additionally, these upgrades included advancements in electronics, encompassing navigation, target acquisition, and a friend-or-foe identification system.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Soviet motor torpedo boat {{Battle-rating}}. It was introduced during [[Update 1.79 "Project X"]] when the Soviet fleet was implemented into the game.

This vessel was introduced during [[Update 1.79 "Project X"]] when the Soviet fleet was introduced into the game. The model was equipped solely with twin 14.5 mm KPV heavy machine guns, contrasting the earlier model's configuration of two twin 12.7 mm DShK heavy machine guns. Despite having half the number of machine guns compared to the previous model, the KPV proved formidable as a heavy machine gun, capable of inflicting significant damage on enemy boats and certain armored vessels due to its API ammunition. Furthermore, it carried two [[45-36NU (450 mm)|45-36NU]] torpedoes, ideal for targeting slower-moving vessels or lower-ranked destroyers and frigates. Additionally, it carried four [[BB-1 depth charge|BB-1]] depth charges, which, if used correctly, could destroy enemy boats and cause massive damage to enemy destroyers.

The Pr.123K "Komsomolets" has one of te best top speeds, acceleration and manouverability in the game for a ship - 135 km/h in AB and 96 km/h in RB. This plays as it's biggest advantage, compared with its small size, it leads to a sort of "hit and run" playstyle.

The Pr.123K has excellent mobility that is very comparable to the reserve G-5 torpedo boat. This ship has an magnificent top speed of 120+ km/h in AB, as well as great acceleration and snappy rudder response. These factors combine with the Pr.123K's small silhouette to make the ship almost impossible to hit at longer ranges - this plays as its biggest advantage, which leads to a sort of "hit and run" playstyle. If you have mastered the playstyle of the G-5 reserve torpedo boat, you will master the Pr.123 easily.

The Pr.123K has half the number of machine guns of the Pr.123bis, but they have a larger calibre (dual 14.5 mm KPV machine guns). This is generally a disadvantage at this battle rating, because the vast majority of boats you will face will have no armour and so volume of fire is more important than the power of the ammunition.
 
−
 
 
−
However, the KPV is a very powerful gun, and with API ammunition it can do considerable internal and crew damage, destroying any other small boat in the game with 2-3 reloads, and even significantly reducing the crew of much larger vessels such as destroyers.  Effective use of the guns requires good understanding of lead and aiming offsets for speed and angle - opponents will often not adequately compensate for your speed, while you can be causing damage at ranges up to 1.5 km.

The guns are mounted in the stern, giving a very wide angle of fire, excluding a relatively small angle either side of straight ahead.

The Pr.123K is equipped with 2 x 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).

The Pr.123K can seem as a downgrade from the previous Pr.123bis, with two less machine guns placed in a position that forces you to expose your side to shoot. However, the ship does have a more powerful set of guns, which can be combined with the ship's excellent mobility to make use of ambush / hit-and-run tactics.
+
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.
−
 
 
−
The Pr.123K does best in base-capturing abilities, as it can easily reach bases before most other boats. Thus, at the start of each game, you should rush straight for the bases. After the bases are captured, you can move into ambush tactics, as the Pr.123K has relatively weak survivability and will be shredded in any brawls. Thus, you have to play very carefully, and always stay at speed, or you will get picked off 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.
 
  
−
Against smaller vessels such as MTBs, the two 14.5 mm machine guns are usually more than enough. However, note that these guns will bob considerably when travelling at high speeds, making aiming extremely difficult. Thus, ambush tactics are important - the boat who shoots first will almost always win the engagement. You should try to ambush other MTBs who are already distracted in order to maximise your ship's survivability. Against larger destroyers, the Pr.123 gets two large torpedoes which are often enough to knock out anything up to the size of a destroyer - make use of these torpedoes to get rid of larger vessels such as early destroyers.
+
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.

Pr.123K "Komsomolets" was the last variant of the Pr.123 series of motor torpedo boats built by the Soviet navy during and shortly after the Second World War. The ship differed from previous Pr.123 versions due to the removal of one 12.7 mm DShK machine gun turret, the installation of a heavier 14.5 mm machine gun turret, and the installation of two Identification Friend-or-Foe (IFF) and target search radars. As well, the ship carried a new design of smoke generator designed to operate for longer periods of time. In total, 205 boats were built from 1949 to 1951.
 
−
 
 
−
The Pr.123K was the final development of the Pr.123 class, and had improved armament and sensor equipment. Compared to the previous Pr.123bis, several changes were made to the basic ship design. The Pr.123K was built with a new, more spacious open bridge, which housed the steering and control equipment. As well, the Pr.123K lost the forward machine gun turret of the Pr.123bis, while the rear turret was upgraded to a dual KPV machine gun turret. The ship had less powerful engines compared to the Pr.123bis (200 fewer hp per engine), but was capable of a higher top speed thanks to a lighter and more hydrodynamic hull. Finally, the ship gained two new radars - the "Zarnitsa" air-search radar and the "Fakel-M" IFF device. Both were mounted on a dome behind the bridge.
 
−
 
 
−
In total, 205 Pr.123K boats were built between 1949 and 1951, several years after their earlier counterparts. Of these, some ships were delivered without the radar installation. Two ships were modified with single and dual hydrofoils (being the A-10 and A-11 models), which were capable of even higher speeds in tests. As well, over 100 Pr.123K MTBs were exported to Warsaw-pact countries. The ships had a long service life, some ships remaining in export service until 1990.

Pr.123K

Description

The Pr.123K "Komsomolets" is a rank Soviet motor torpedo boat with a battle rating of (AB), (RB), and (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.

Mobility

The Pr.123K "Komsomolets" has one of te best top speeds, acceleration and manouverability in the game for a ship - 135 km/h in AB and 96 km/h in RB. This plays as it's biggest advantage, compared with its small size, it leads to a sort of "hit and run" playstyle. If you have mastered the playstyle of the G-5 reserve torpedo boat, you will master the Pr.123 easily.

Armament

Primary armament

Main article: KPVT (14.5 mm)

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). This is a generally disadvantage at this battle rating, because the vast majority of boats you will face will have no armour and so volume of fire is more important than the power of the ammunition.

However the KPV is a very powerful gun, and with API ammunition it can do considerable internal and crew damage, destroying any other small boat in the game with 2-3 reloads, and even significantly reducing the crew of much larger vessels such as destroyers. Effective use of the guns requires good understanding of lead and aiming offsets for speed and angle - opponents will often not adequately compensate for your speed, while you can be causing damage at ranges up to 1.5km

The guns are mounted in the stern, giving a very wide angle of fire excluding a relatively small angle either side of straight ahead.

Additional armament

Main articles: 45-36NU (450 mm), BB-1 depth charge

The Pr. 123K is equipped with 2 x 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).

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

Pros:

  • 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.

Cons:

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

History

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).

Media

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