General info
Survivability and armour
Being a light Anti-submarine Frigate, the Pr.35 "Mirka" class has very little substantial armour, with 5mm turret armour and the 15mm splash guard for the forward turret. While these may minimize damaged caused by small caliber HE and splash damage from other areas being hit, they will not protect the turrets from direct fire starting at even the size of 12.7mm machine guns. General survivability is not much better, as the primary armament is limited to two large turrets. Losing turrets is common on the Mirka and will result in your fire being halved at the least. Furthermore, the low crew count of 98 means that a very low damage threshold can be sustained on major components before the ship is destroyed. Thankfully the Mirka has a few aces up its sleeve to counteract these issues. To begin with, crew are very spaced out in the ship, meaning that you will most likely survive the first few salvos. Secondly, because the hull has such a low freeboard for the majority of the ship, most of the machinery and ammunition is protected by the sea.
Overall the ship's survivability is below average, with its low crew and few turrets being the brunt of the issue.
Mobility
Mobility is a very strong suit of the ship. Starting at 57km/h stock the ship lags behind destroyers and most cruisers, and cannot hold a candle to the late-game MTBs that it might face. However of the Corvette/Frigate class, the Pr.35 has a distinct advantage, often holding a 10km/h advantage or more over other ships of its size. These are rarely faced however, and as such it cannot be expected that you will ever be leading the charge in matches. The turn radius of the ship is reasonable, however the initial snap can be very deceiving when initiating a turn. One major issue when maneuvering the Mirka is the existence of the hull mounted Sonar system. This dips far below the keel of the hull and can often be caught on rocks. Special attention must be given when maneuvering around shoals and beaches where the Sonar might hold fast.
Armament
Primary armament
The Primary armament of the Pr.35 is where the ship shines. It is armed with a pair of AK-726 76mm semi-automatic gun turrets. Each of these turrets contains two guns firing a total of 90 rounds per minute. This fire rate allows for the ship to dismantle any opponent vessel in seconds, from MTBs all the way up to destroyer leaders and light cruisers. These guns have very nice post-penetration effects on targets lacking armour, and can be extremely dangerous should you sneak up on someone. This fire rate comes at a price, however, and that price is two fold. Firstly, the guns overheat quickly, barrages tend to be limited and the guns must be watched for overheat. Secondly, the shells have a relatively short range and their effectiveness drops off quickly beyond 5 kilometers, when shells begin to miss and fire arcs become to great to regularly hit the target.Torpedo armament
The Pr.35 "Mirka" is armed with a single quintuple 406mm torpedo launcher armed with the SET-40 lightweight anti-submarine torpedo. The launcher has very good launch angles and 5 torpedoes is quite reasonable however that is where the praise ends. The torpedoes have only 1 setting, with no option for upgrades and are slow. At 54km/h a cruiser with keen eyes can outrun these torpedoes and with 8 kilometer range they are not going to reach much past the effective range of your turrets. Worse still the torpedoes have a meek 80kg warhead, which will not kill ships larger than a corvette in one hit. These torpedoes have limited use in surprising unsuspecting captains should you face something armoured such as a heavy cruiser, and can be used should the main battery fall silent, however they are unlikely to kill without multiple hits, and must be used at a range where they cannot be avoided easily.Special armament
The Mirkas round off their armament with 4 RBU-6000 anti-submarine rocket launchers, each carrying 12 rockets to total 48. being rockets they have a limited effective engagement range, high arcs of fire and are very hard to aim in conjunction with primary weapons, however should a small boat decide to get too close or should you decide to engage a target at point blank range, the barrage of 25kg warheads smashing into the superstructure and hull of the hostile ship will almost certainly cripple it, if not outright sink it.
Usage in battles
The Pr.35 excels in close quarter brawling with anything its shells can penetrate. Captains of the Pr. 35 should attempt to close the distance on any target and engage with their guns within 5 kilometers for maximum effectiveness, reserving torpedoes and rockets for extreme close quarters or emergencies. Because the guns only fire HE, captains of the Mirka should avoid engaging cruisers, as they may find penetrating and damaging the components of cruisers difficult. Should you choose to engage one, torpedoes and rockets may be necessary to destroy the target. Critically, captains should avoid wide open ocean, as they will draw fire from targets that they cannot engage themselves, and invite would be bombers to surprise them before they can engage with the guns.
Pros and cons
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".
Pros:
- Extremely high fire rate
- Good gun handling
- Small target to engage
- Decent maneuverability
Cons:
- Guns overheat quickly
- Torpedoes are next to useless
- poor survivability
- 2 turrets, easily knocked out
History
Describe the history of the creation and combat usage of the vehicle 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 vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-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 vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === Encyclopedia Info ===, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
