Description

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.

Mobility

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.

Armament

Primary armament

2 х Turret85 mm/54.6 ZIS-C-53 cannon

Ammunition180 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

Ammunition2000 rounds

Belt capacity5 rounds

Fire rate180 shots/min

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

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 MBK Pr. 186 (MK 85) is quite an interesting ship to play, due to it's unique set of characteristics - heavy armament, good armour, and rediculously bad maneuverability. With a pair of hard-hitting 85 mm cannons slapped on a hull with some anti-aircraft armament, this ship is very well suited for a certain set of playstyles and can excel in a variety of situations if used correctly.

Tactics:

The MBK Pr. 186 can work very well in certain situations, particularly longer-range engagements. This is because of it's great weapons load, namely two 85 mm cannons. While they don't fire particularly fast, they hit very hard and can do a lot of damage to naval targets. Assuming you have decent accuracy, you can easily sink any ships at the Pr. 186's BR with a couple of shots. However, note that the Pr. 186 does also have access to a powerful Soviet 37 mm 70-K cannon mounted behind the bridge - this weapon is much more suited for dealing with fast vessels and aircraft, as it can fire continously against any targets that the 85 mm guns cannot hit as easily. Finally, the Pr. 186 has access to four 12.7 mm machine guns in two twin turrets, which can serve as an effective anti-aircraft armament alongside the aforementioned 37 mm cannon.

The MBK Pr. 186 is quite survivable, with 42 crew members and armour up to 30 mm on the hull. The 85 mm gun turrets are also well-protected with 30 mm of armour, though this is less than the tech-tree version which gets up to 90 mm of armour. This armour provides the Pr. 186 with extensive protection which makes it impervious to most small-arms fire, meaning that it could potentially be used as a brawler against smaller PT boats and coastal vessels. However, the ship's survivability should not be relied upon exclusively, as the ship will easily be destroyed by the larger coastal ships and destroyers that it faces often. Instead, captains should rely extensively on available island cover to protect their ship. In the case of an open map (the conquest maps), try to stay further away from enemy bluewater vessels to maximize survivability.

Finally, the MBK Pr. 186 suffers from a rather terrible maneuverability, with a poor turning circle and a rather disappointing top speed of 26 km/h in RB. Thus, the ship cannot be relied upon to capture zones, as it will take ages just to get to the capture point. In general, this ship should be played as a longer-range sniper, maximising the use of it's powerful armament.

Pros and cons

Pros:

• 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
  • Good crew count for it's size, 42 crew members
• Armour provides significant protection against machine-guns and small caliber cannon HE ammunition
• Low silhouette, making it rather difficult to hit at longer ranges

Cons:

• Slow, with a top speed of just 26 km/h in RB spaded
• Secondary armament is located in a weird position, limiting firing arcs for the 37 mm and 12.7 mm guns
• Faces early destroyers very often, where it has a significant survivability disadvantage
• Part of the bow and the entire stern is unprotected, leaving a large part of the ship's crew vulnerable
• Gun turrets are less armoured than the tech tree version

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 />.
