Description
The MPK pr.122A is a rank II Soviet sub-chaser 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
Due to its large size and decent crew, this is a difficult boat to sink. The whole vessel is unarmoured except for the gun shield, meaning that machinery and ammunition are left exposed. Although magazine explosions are rare, it's common for both the gun and engine to be knocked out, either of which will spell disaster for this vessel. Fortunately, due to its size, the crew is spread out and there are more compartments to disable, increasing your life expectancy greatly.
Mobility
The boat is reasonably fast in a straight line, able to keep up with slower PT boats and outpace German minesweepers. However, turning is awful due to large hull length. The boat tends to spin, meaning the stern will hit rocks or the shoreline if sailed too close. Stopping distance is also a problem, with no easy way to escape trouble once you've found it. All in all, it has decent mobility, adequate for the role, but it does have some shortcomings to be mindful of.

Armament
Primary armament
Primary armament consists of a single rapid fire 76 mm gun positioned on the bow, which is able to shred smaller boats in a few hits while holding its own against larger vessels. The gun is protected by steel plate, however due to its position, it will often get knocked out by enemy fire.
HE is deadly against small and medium-sized vessels, disabling compartments in one or two hits. While AP is good for armoured targets such as the Soviet gunboats, it will over-penetrate most vehicles this boat will face.

Secondary armament
Secondary armaments that also double for anti-air duties on the vessel are the three 12.7 mm DShK heavy machine guns in single mounts at the stern. While they may be classed as combined AA/auxiliaries, they are only really useful for engaging aerial targets. Due to the location of the guns, they have decent firing arcs and have no problem tracking low flying aircraft. Optimal range for these guns is less than a kilometer, where their combined fire will easily down any aircraft that loiter in the vicinity, while gunners will start opening up from 2 km away.

Additional armament
While depth charges and bomb throwers can be equipped, they are mostly useless and should only be used in specific situations, otherwise concentrate on using the guns.
Usage in battles
(AB) The ship should be pointed towards the bow (front) at all times, greatly increasing survivability, and used to hunt smaller PT boats with the 76 mm cannon while staying away from larger ships with bigger or more numerous guns. While this boat isn't immune to PT boats, they are its primary target, and parking the boat behind cover near a cap allows you to mop up any intruders. Particular enemies to note are:
- Well-armed American PT boats (PT-314, etc.)
- British and Soviet gunboats (SGB, Fairmile, MPK-163)
- German barges (SF40's or AF D1's)
- British Isles/Flower-class boats
- Also large, tough bombers such as the Catalina or Wellington will break through your air defence, try to keep moving and not make yourself an easy target.
Pros and cons
Pros:
- Rapid-fire cannon, which deals decent damage
- Self-defence AA is capable of shooting down planes at short range (1 km or closer)
- Fast in a straight line
- Good survivability
Cons:
- Auxiliary armament of 3 heavy machine guns are mostly ineffective against other ships, and A.I. Gunners tend to be inefficient
- Big turning circle and big length mean difficulty traversing in tight spaces - beware of running aground
- Cannon does get knocked out easily
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).
