Armament

Primary armament

4 х Turret130 mm B-13 mounting
Ammunition150 rounds
Vertical guidance-5° / 45°
Main article: B-13 (130 mm)

The Pr. 7U "Stroyny" carries four 130 mm B-13 single mountings, with two turrets ahead of the superstructure and two behind. The B-13 cannon is shared by most WWII-era destroyers of the Soviet fleet, and is a very potent weapon. However, the main flaw with this weapon is it's absolutely horrid turret rotation speed of 4.2 degrees / second vertically and horizontally. This means that you have to turn the turrets very early to be able to engage effectively. The guns themselves shoot accurately and have a high initial velocity (870 m/s compared to 790 m/s for the American 5"/38 guns). However, this comes at the expense of reload speed, as the manually-loaded weapons can only fire at 10 rounds per minute (RPM) with a spaded crew, compared to 22 RPM for the American 5"/38. In fact, this fire rate is slower than everything except for the Japanese and Italian 5" guns, which have a similar fire rate.

The guns themselves have access to three shell types: the OF-46 high-explosive (HE) shell, the PB-46A semi armour-piercing (SAPBC) shell, and the ZS-46R proximity-fuzed (HE-VT) shell. Of these weapons, the HE shell is usually the best against enemy destroyers and ships as it packs the most explosive filler, 3.58 kilograms of it to be exact. The SAPBC shell works better against the occasional cruiser you may encounter, as it packs more penetration capacity (up to 179 mm compared to 36 mm for the HE shell). Finally, the HE-VT shell is good against aircraft as it will explode when close enough to the enemy aircraft, meaning that it doesn't require a direct hit. However, it actually packs less explosive filler than the normal HE shell, which is unusual for any HE-VT shell. Combined with the horrible traverse rate, this means the guns aren't particularly suited for anti-aircraft duties.

Secondary armament

3 х Turret76 mm 34-K mounting
Ammunition300 rounds
Main article: 34-K (76 mm)

The Pr. 7U "Stroyny" carries three 76 mm (3-inch) 34-K mountings in single mounts, all at the rear - one additional mount than it's tech-tree cousin, the Pr. 7U. The 34-K is also shared by most WWII-era Soviet ships, and gives you a potent secondary weapon that is of a relatively high calibre. This gun has a high fire rate of 27 rounds per minute (2.2-second reload), which can be decreased to 1.1 seconds with a full crew. The weapon itself is decent at closer ranges, but isn't a particularly effective anti-aircraft weapon as it inherits the extremely weak Soviet traverse rate. The single mountings themselves are only capable of traversing at 10 degrees per second, marginally faster than guns of cruiser calibre (6 inch+) of other nations.

The gun itself has access to three main shell types - the O-361K high-explosive (HE) shell, the O-361D time-fuzed (HE-TF) shell, and the BR-361 armour-piercing (APHEBC) shell. Of these rounds, the HE is almost always the best against enemy boats as it has the most explosive filler, and consequently, does the most damage. The HE-TF round is slightly worse as it detonates on a timed fuze, meaning the accuracy of the shell depends on crew skills. Finally, the APHEBC shells are rarely usable due to their low damage potential. For good measure, bring mostly HE, and a bit of HE-TF and APHEBC just in case the situation arises.

Anti-aircraft armament

6 х Turret37 mm/67 70-K automatic cannon
Ammunition2000 rounds
Belt capacity5 rounds
Fire rate180 shots/min
4 х Turret12.7 mm DShK machine gun
Ammunition2000 rounds
Belt capacity50 rounds
Fire rate600 shots/min

The Pr. 7U "Stroyny" actually has less anti-aircraft armament than the tech-tree Pr. 7U, but still more than enough to defend itself from any airborne threats.

The primary backbone of the Stroyny's anti-aircraft armament are it's six 37 mm 70-K anti aircraft guns. The 70-K is the standard Soviet anti-aircraft gun and serves as a reliable counterpart to the 40 mm Bofors gun used by the allied nations. This gun is extremely similar to the Bofors as it features a similar design, and fires continuously rather than needing to reload. The guns will eventually jam, but the time it takes to jam the weapons is very long so jamming is not a great issue. The weapon does not get access to belts, but the default one is very suited for ripping small ships or aircraft into shreds.

The Stroyny also carries four 12.7 mm DShK guns in single mountings. The 12.7 mm DShK machine gun is a heavy machine gun, similar to the M2 Browning used by the Americans and the Vickers guns used by the British. This gun fires from a fixed 50-round magazine and will need to be reloaded after the magazine is expended. The gun itself is rather mediocre, and will struggle to hit targets reliably at ranges exceeding 1.5 km. As well, the weapon doesn't do damage particularly well, considering that it is of a lower calibre. The Stroyny does not get access to any ammunition belt upgrades - the default one is the only belt available.

Additional armament

Setup 16 x 533 mm 53-38 torpedo
Setup 22 x BB-1 large depth charge
Setup 36 x 533 mm 53-38 torpedo
2 x BB-1 large depth charge

The Pr. 7U "Stroyny" gets access to six 53-38 torpedoes in two triple mounts with no reloads. The 53-38 torpedo is also found on most other Soviet WWII-era destroyers, and is relatively mediocre as far as torpedoes go. In terms of damage-dealing capabilities, the torpedo is decidedly mediocre, having more explosive filler (300 kg of TNT) than the American torpedoes but less than the British and Japanese ones. However, the main drawback of the torpedo is it's range - without the "torpedo mode" modification, the 53-38s are restricted to a range of just 4 kilometres, meaning that they are tied for the shortest-range bluewater-ship mounted torpedoes along with the Italian destroyer torpedoes. The torpedo mode modification is necessary for hitting longer-ranged targets, but reduces the torpedo's speed to just 56 km/h. In general, these torpedoes are a potent weapon against enemy bluewater ships, but lack the range to do significant damage without the "torpedo mode" modification.

The Pr. 7U "Stroyny" can bring two BB-1 large depth charges, but these weapons are almost entirely useless as you will never get close enough to the enemy to be able to use them. Thus, they essentially serve as extra explosive content on deck, and provide little extra armament in exchange for an increased chance of ammunition (depth charge) detonation. In general, it is not recommended to bring them.

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

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".

History

Stroyny was one of the final ships from the renowned Type 7 series. In fact, she hadn't even undergone the required tests before the start of the war. With only one commissioned engine, Stroyny proceeded to the Ust-Izhora shipyard and engaged the German troops assaulting Leningrad. While the city was under siege, the destroyer's crew laid down continuous fire on the enemy positions and provided fire support to the Red Army troops breaking through the blockade. According to the official data, Stroyny's primary armament fired a whole 5,424 rounds on the enemy during the Siege of Leningrad! Due to such intense levels of fire, the ship's gun liners – the special insertable tubes with cuts that are used in gun barrels – had to be changed twice. After the blockade was broken, Stroyny was stationed in Leningrad, where it remained until the war was over. In the post-war period, the destroyer was converted into a rescue vessel and later on used as a target ship. Stroyny was retired from military service in 1965.
