The MBK pr.186 (MK 85) is a premium rank IV Soviet armoured gun boat with a battle rating of 3.3 (AB/RB/SB). It was introduced during Update 1.83 "Masters of the Sea" with the fleet release into open beta test.

The MBK pr. 186 (MK 85) has significantly more armour than its predecessors all-around, and can take a fair beating as a result. The middle portion of this ship has 30 mm of rolled homogeneous armour, while the front and back have protection of 8-12 mm. This defence makes machine gun fire much less dangerous, almost a relic of the past. However, this additional armour makes this ship much heavier, and detrimentally effects the speed, as elaborated in the next section.

The 85 mm gun turrets have significantly less armour than the main tree version.


Speedforward / back
AB35 / 13 km/h
RB26 / 10 km/h

The MBK pr. 186 (MK 85) has an abysmal top speed 35 km/h in AB. The turning speed is also terrible, and it will take more than a dozen seconds to completely turn around, however it does start the turn quite rapidly, making dodging torpedoes a reasonable option. Due to this fact, the vessel must be played with very strategically chosen movements, as becoming exposed with no quick way out is one of the most common ways to be destroyed in this ship.

Primary armament

2 х Turret85 mm/54.6 ZIS-C-53 cannon
Ammunition100 rounds
Vertical guidance-5° / 77°

The MBK pr. 186 has two 85mm guns in single turrets as its main guns. These guns fare fairly well against medium sized ships due to their reasonable caliber, and can sometimes hull-break small ships, although small enough ships are seldomly encountered at this battle rating. Up until this point, HE shells were the indisputably best shell for naval combat due to the lack of armor anywhere. HE should be your usual load, although APHE shells are useful vs other armoured gunboats, and also sometimes against larger vessels.

Secondary armament

Turret37 mm/67 70-K automatic cannon
Ammunition1500 rounds
Belt capacity5 rounds
Fire rate180 shots/min
Main article: 37 mm/67 70-K (37 mm)

A single 37mm autocannon comprises the secondary armament. This is the same model as the one used on the Pr.1124 (1945) and the BMO as well as the MPK-163. This gun is a fairly good secondary gun due to its caliber and good rate-of-fire, and can tackle both small to medium sized ships and most air targets.

Anti-aircraft armament

2 х Turret2 x 12.7 mm DShK machine gun
Ammunition4000 rounds
Belt capacity50 rounds
Fire rate600 shots/min
Main article: DShK (12.7 mm)

Two twin-mount 12.7mm DShK turrets that are mounted on the sides of the command bridge at the center of the ship. As such, only one turret can engage a target at a time due to the interrupted arc of fire unless the target is directly in front or behind the ship. This is not the most desirable positioning but it will work most of the time deterring air attacks, with the help of the 37mm autocannon.

Usage in battles

The vessel is best at medium distance combat, due to the power of its 85mm cannon. It can easily destroy all other vessels in its class by aiming for the hull sections and destroying them in turn - 3 well aimed salvos will destroy most PT-sized boats. It is not suited to close quarter or ambush combat due to its slow speed, however if it finds itself in such a position its firepower can be enough so solve the situation.

Pros and cons


  • 2 x 85 mm provide plenty of firepower to destroy boats
  • Secondary and AA armament is on a par with the main armament of most other PT boats
  • Armour provides significant protection against machine-guns and small caliber cannon HE ammunition


  • Slow
  • Turrets have less armour than main tree version


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).
