Pr.191M

Description

The Pr.191M is an upgraded, production version of the Pr.191. It features new M-50 engines, making the boat slightly faster, addressing a key issue with the previous version. It is also equipped with new 14.5 mm KPV heavy machine guns, replacing the older 12.7 mm model. The boat entered production in 1947, although there were initial issues with the hull's bottom, which were later resolved. A total of 188 Pr.191M units were produced between 1947 and 1954, with most being assigned to the river patrol fleet.

In the game, this boat was introduced during Update 1.79 "Project X" when the Soviet fleet was implemented into the game. It retains the same crew count and armour layout as the previous version but has a faster speed. The boat still uses the 85 mm cannon but now comes equipped with a 14.5 mm KPV heavy machine gun that can penetrate up to 40 mm of armor at close range, making it effective at destroying enemy boats and some armoured targets. It also has magnetic mines, though they are not particularly effective at sinking enemy destroyers.

General info

Survivability and armour

Positive aspects:

• The hull is made of 6 mm steel, this can stop some small calibre HE rounds and the occasional shrapnel.
• The armoured sections were designed to withstand rifle-calibres, and will not protect you against 20 mm AP and larger rounds.

Negative aspects:

• Armour doesn't cover 100% of any compartments, meaning any HE that pierces more than 5 mm can destroy any compartments except the superstructure
• Low crew of 14
• 85 mm ammo isn't protected by any armour plates

Armament

Primary armament

The 85 mm/54.6 ZIS-C-53 gun is one of the best guns you will ever find at this battle rating. This gun's HE is able to penetrate most if not all ships it faces, but it is recommended to keep a few APHE just in case.

BR-365	APHEBC	792	9.2	1.2	14	164	48°	63°	71°

Secondary armament

Secondary armament consists of 2 turrets equipped with dual 14.5 mm KPVT heavy machine guns. The KPVT was designed to destroy light vehicles, and can penetrate up to 40 mm of RHA close up. This is not to be ignored, the round will go through the aircraft's armour and engines like butter, wrecking anything in its way. This also means the KPVT can deal significant damage to other PT boats.

As AA guns, these will do well at close ranges up to 2,000 m. They will have difficulty against anything further away, and aren't well suited to attacking medium and large bombers.

Additional armament

The ship comes with 12 MIRAB mines. These mines are rather small, and should be used mostly against corvettes and smaller vessel. A destroyer will survive a hit without issue, and anything hitting a torpedo bulge won't deal any damage. These are best used in small capture points against other PT boats.

Usage in battles

Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons

Pros:

• 85 mm main gun will be useful against all types of targets up to destroyer size while 14.5 mm KPVT gun will help against close aircraft and PT boats
• Armour can withstand up to 12.7 mm rounds, this will stop shrapnel and many aircraft guns

Cons:

• Low crew of 14, the compartment aren't fully covered in armour, meaning some HE salvoes may knock you out instantly
• Low speed of barely over 30 km/h, making you a great target for canons
• Lacks any decent medium/long range AA
• Shallow draught causes the boat to constantly rock in sea conditions, hampering accuracy

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).
