The **Vizverzidezhannyy-class**, (Rossi: Висверзидешний, synonym for "Gallant") also known as the '**Vizviy**' (**Vizvie** for English speakers, Висбй in Cyrillic.) class destroyer, Russian designation: Project 956 "Badger" is a class of guided-missile destroyers built for the Russian Maritime Force in service during the 1st Great Cryptid War. Between (O.S) 1851 to 1856 (451 - 456APF) a total of 53 ships built while 15 ships being modified for various purposes. The Vizviy-class' design was generally liked by crew and noted for it's drastic distinguishing features compared to the previous Sovremennyy-class, with a larger light cruiser like size, a design speed of 40 knots, improved crew accommodation and better protected crew and weapon systems.

The Vizviy-class is also hailed by the Russian Armed Forces for it's powerful armament and advanced technologies, using twin 125mm/55 AV-1/2 naval gun turrets, sophisticated S-23 missiles, dual rudders, improved anti-aircraft capabilities, underside armour and other improvements. These fleet destroyers performed every task required of it, from escort missions, anti-submersible combat, air defence duties, surface combat while covering vast distances at sea. Which was important to the Russians and their lack of naval infrastructures in the Cryptid frontlines. Many of the Vizviy-class destroyers found service in the Altay Strait, Kripta Sea and most prominently as escort anti-aircraft ships defending Kjeragi merchant routes during the Sino - Singappon War in 1850. All accounted for only 29 ships were lost in the war, only 4 of which were destroyed by enemy warships.

The Vizverziderzhannyy-class was designed to be supplemented by the Bespokoinyi-class as followed by Russian naval doctrines — Vizviy-class providing anti-submersible and anti-air defence whilst the Bespokoinyi provides gunfire and surface combat roles. Both classes served with distinguished careers.

## Namesake

The word Vizverzidezhannyy was considered "The youngest word in the Russian language. First issued in dictionaries in (O.S) 1849 by orders of the Winter Palace as a way to promote heroism in the Russian Army. The namesake of the word and the ship class belonged to Lieutenant Ilyana Simonovich Vizvy (The Ruby Sword recipient and Cross of St. Georgi C5) for her last stand during the Siege of Um which spared the lives of 165 troops which rewarded her The Ruby Sword medal posthumously. Her gallantry and documented heroism became perfect for the Russian Armed Forces to promote, subsequently becoming the face of many Russian propaganda campaigns, including the adjective of Vizverziderzhannyy.

Many of the Vizviy-class ships had other namesakes which had themes of heroism. Majority of the ships which in service with navies to other nations, a pair of ships were delivered to the Jamin Feng Navy (JFN) for lend-lease. The vessels seeing service with the JF Navy were known as the 'Hero-class' (JF Official Designation: Class 2B9-E) which also followed the naming convention of the Vizvie.

## Design

### Construction

The Vizvie-class is large for a destroyer, but smaller than a cruiser, which the Russian Navy deemed best suited for economic series production, as it meant the Russians could downscale the production of light cruisers and save significant costs due to the new, larger sized destroyers of comparable capabilites. Detailed design changes eliminated some of the problems seen during trials of the original Sovremennyy-class such as spaced thermal sleeves to prevent machine distortions from background temperatures, enlargened gear and shaft complexes for increased engine service life, and seawater cooling systems supplied by the ship's ballast tanks for keeping electronics and engine equipment cool, with said equipment themselves having provided redundancies to protect against environmental conditions that may damage it.

The ship is also very balanced, using variable-volumet ballasts which is used for preventing ship tipping in the event of flooding damage. These ballasts also are used to store seawater for cooling systems.

Many of these ships have followed cost cutting measures to prevent any delay in construction time in the ship. Many subassemblies have been built specifically for destroyer production:

* Shipyards in Altay, Arkhangelsk, Sapporo and Karakatya build prefabricated ship sections for assembly
* Kirov Naval Plant supplied the ship's 'Schchit' naval armour.
* OP Osseniya Heavy Industry produces the DO-190 gas turbines, DDO-93 diesel engines and turbo-electric transmission system.
* KKB Magdiesew produces the AV-1/2 turret mounts for 125mm guns.
* KKB Avtomaschinaarlenika produces the ship electronics and radar systems.
* Sankt Konstantin Machine Plant produces ship auxiliary and improved performance components.

The design of the Vizviderzhannyy-class was originally based on a proposed large 2,300 ton design having decided to be enlargened to 2,805 metric tons, which is 505 tons overweight than its original designed tonnage and 3,665 metric tons at deep load. The ships of the Vizverziderzhannyy-class were among the largest destroyers built in Russia, with a wider flaring bow design and a more hydrodynamically efficient water-plane form with a hull designed to be of all steel construction, using a reinforced bow and all bolted segments the ship. The Vizvie had an overall length of 66.4 arshina (129 meters), a beam of 6 arshina (11.9 meters) and a draft of 2.04 arshina (4 meters) at deep load, standard load being at 2.55 arshina (5 meters). The crew complement consisted of 291 sailors and officers.

### Protective Measures

Much of the ship was divided into separate sections belonging to other manufacturers which was then assembled in a singular drydock for mass production. Each section is built with four fuel rod cells on each side, contained within the ship's bilge ballast, divided by the crew compartment in between. Each section are protected with bakelite anti-spall lining. Bulkhead doors being 25mm thick for improved crew survivability. Two electric cable complex encased in 1 arsen (5.7mm) of aluminium-steel alloy insulated by 2 mer (1.6mm) of high resistance rubber matrix is found running along the ship's axis on opposite sides atop the waterline, these cable complexes are wired to the electronics systems found within the vessel, these two cables are redundancies, in the event of a damaged complex the secondary can take over and maintain the ship's working order.

Fire suppression is automatic, provided smoke detectors and water sprinklers. With additional water hoses, fire extinguishers, thermal shielding and heat-resistant firefighting gear to improve fire damage control conditions.

### Schchit Underwater Protection System

The ship uses the 'Schchit' underwater protection system. This system was designed to resist minor torpedo attacks and Cryptid seamonster damage, this is a type of impact protection system which is able to simulate torpedo bulkheads without causing an increase in beam and compromising the turn rate. The system consists of two major components:

* The Schchit shield
* The variable-volumet ballast

The shield consists of a relatively thin outer 'bumper' plate with some distance from the main hull. The outer plate itself wasn't expected to stop the incoming threat but instead was designed to break up and distribute the energy of the impact where it is spread more thinly throughout the ship's hull, which in theory will be able to prevent any major armour penetration. The plate is evenly spaced between two 25mm thick special treatment soft steel with thin multi-shock trusses sandwiched in-between to maximise shock absorption.

For preventing shockwave damage the variable-volumet water ballasts serve to improve survivability conditions of the crew inside, the fuel rod cells within the ballasts help in improving the protection by the ship using the ballasts as a last ditch measure to ensure crew protection. A bakelite anti-spall lining is inserted into the walls between the volumet buffer and the main compartments. The addition of the volumet tanks was controversial; as the addition of such tanks made for a cramped working space for crew operators in lower decks of the ship bilge. However at the cost of relatively superior underwater protection.

### Propulsion

The ships were powered by a CODAG propulsion set, consisting of the DO-190 gas turbine engine and the DDO-93M diesel economy engine which drove the turbo-electric transmission system consisting of three Kolombarskiy AVM-33-2 electric generators generating 80 kilowatts, power clutch controls and two shafts all designed and built by OP Osseniya and Kolombarskiy. The propulsion system each driving a pair of pumpjet centrifugal-flow pump paired with two shark's-fin style rudders using power provided by both the diesel and gas turbine engines. Two pair of lateral thrusters containing additional pumpjets powered by the AVM-33-2 generators for improved maneuverability. The DO-190 turbines operated at a pressure of 51 kg/cm² and a temperature of 445°C at 32% thermal efficiency which was regularly regulated by the ship's seawater cooling system. The turbines could produce a total of 46,000kW.

The diesel engines fair better for the Vizverziderzhannyy-class at economic cruise. With a V-12 opposed piston engine with a maximum operating speed of 1000rpm with pressures of 28 kg/cm², the diesel engine is rated to produce 8,000kW at maximum speed. The CODAG propulsion intended to give the ships a speed of 40.3 knots (74.7km/h). The designers had allowed for leeway for the ship to exceed its standard maximum speed of 40.3kn, however the Russian Navy does not recommend exceeding the Vizviy's maximum speed. This was apparent during various speed trials where ships like Galantnost' reached 44 knots (81km/h). But due to variation of fuel needed and wartime shortages meant that speeds were best kept between 34 knots (63km/h) and 37 knots (69km/h) in order to not consume too much fuel in combat. The range of the Vizverziderzhannyy was rated to be at ~2,100km at 40.3kn. However at 18 knots (33km/h) speed using the DDO-93M engine, the Vizviy fairs better in range at 17.3 dalek (11,250km). All engine compartments have been divided accordingly into individual airtight subdivisions with exception to the mechanical transmission of the system.

The underside of the ship is equipped with bilge keel and anti-roll fin stabilisers which are electronically connected to the gyroscope stabiliser system. The 4U2P anti-roll gyroscope stabiliser suite was the main stabilisation equipment found within the Vizverziderzhannyy-class. It consisted of a 7 ton, 1 arshina (1.95 meter) diameter flywheels mounted near the center of the ship, between the engine rooms and spun at 6200 rpm by 50kW AC electric motors and are cooled down by seawater and glycol vials to maintain the high spin rate. The gyroscopes' cases were mounted on vertical bearings protected by a 7mm steel shell. When a small sensor gyroscope on the bridge sensed a roll, a servomotor would rotate the gyros about a vertical axis in a direction so their precession would counteract the roll. Additional instruments to improve anti-roll capability uses a twin-axis liquid level ruler, a shift calculator connected to an electromechanical computer which operates the ship's anti-roll control planes in order to exhibit -/+1.89° of roll which was deemed significant compared to the previous destroyers which lacked stabilisation.

For providing superior flooding control compared to preceding destroyers in the navy, each engine is equipped with a 1kW battery for cold starts, power in the ship can be redirected to the engines as a last resort. Both gas turbine and diesel engine are sat atop a depression which is equipped with a water pump connected to the ship ballasts, which is made much smaller with the deletion of the fuel rods which are replaced by smaller springboard shock absorbers to better fit crew and workers. The depression both works to add more accessibility to the engine's internal components and also be used as flood water collection to prevent any from entering it. The sides of the engines are armoured by 13mm high-tensile steel plating on the sides.

### Fire Control Systems

#### Aragats Compact Electronics Suite (ACES)

As the main heart of the Vizverziderzhannyy-class, the Aragats Compact Electronics Suite, or ACES for short is a family of military-grade digital computer systems designed for fire control application for the Russian Navy. Designed by the Sarovsnigrad College of Precision Machinery headed and supervised by Senior Lieutenant Anton Sviatovl. The system is partially electronic and partially electromechanical, consisting of an array of high-power computer systems which can perform a variety of tasks from fire control, radar processing, onboard crew and ship-to-ship communications. These computer systems are located in the ship 'Battlestation' (name of CIC) and all units are encased in 25mm special treatment steel, shock hardened armoured boxes with liquid cooling integrations which significantly increases each unit's service life. Assessment of results of fire control systems capable of dealing automatically with the help of digital computing facilities. The operator functions are to control over the work battle management and implementation of missile launch. In a complex environment, operators can manually intervene in the course of combat operation, using electromechanical auxiliary systems.

Typically there are five digital computer units in the Vizviy's battlestation, with two or three electromechanical analogues. All carrying primary and extrasystemic equipment:

* One 5Ae31 Aragats-I, digital, for storing data and processing, with radar and sonar controls.
* One 5Ae32 Aragats-II, digital, for 125mm gun fire control.
* One 5Ae33 Aragats-EE, digital, for calculating high-angle deflection for AA armaments.
* One 5Ae34 Aragats-RL, digital, for surface-to-air missile control.

* A pair of 10Ko106 digital communications switchboards, for onboard deck and ship-to-ship communications.
* One 5Ae38 Aragats EVM-EVM, electromechanical, for ballistic calculations and displaying fire solution data.
* One 5Ae38 Aragats PL-SP, electromechanical, provides real-time aim correction fire solution for follow-up artillery shots.

An example of an Aragats system.Word processing unit of the Aragats-I.The Aragats-I computer processing array, with memory banks visible.An example of an Aragats-RL.Each computer had a speed thousands of times faster than that of electromechanical ones; this computational power significantly added an edge to the Russian Navy's gunnery capability. The high processing power combined with its speed allowed for thousands more calculations for problems, as the Aragats system could calculate a fire solution in 10 - 60 seconds that took humans longer, and even with a greater accuracy.  The entire computer array is divided into five units, with 6,200 7VT7 pentode thernionic valve vacuum tubes, protected by sheet metal cylinders consuming 260kW with 6,153 7D14 quartz piezoelectric crystal diodes combined with 7D16 double diode triodes combined. 1,566 relays, 70,000 resistors, 10,000 capacitors ran by a 2.25MHz clock. all built by precision machining. The Aragats was a large, modular computer array, carrying a powerful memory bank of 1,000 bytes and capable of performing 1,905 operations per second.

##### 5Ae31 Aragats-I

The memory bank is part of the 5Ae31 Aragats-I computer, a mercury delay line type bank, with 1.1 kb of memory. There are 16 channels each containing 15.625 bytes, 3 of which delay lines is used to run the computer systems and it's temperature control. A single 10 byte channel is used for the operator's input mechanisms. Additional 600 kilobytes are found behind the main memory, with a pair of mercury tanks. The system could also read metal magnetic tapes complete with a card puncher/reader which can read data 10 bytes per second.

The Aragats is the most powerful and most complex military computer array available to the Russian Navy. It is also heavy, weighing 1.36 T'yali (10.1 tons) and took up 20.4 ae² (40 m²) space.

The 5Ae31 Aragats-I was the main processing system for the battlestation. The Aragats-I also runs the system B/E scopes, screens, oscillators and so forth. Later models uses a large circular semi-automatic combat environment (SACE) monitor which information was fed to the screens from the ship's radars as well as readiness information from various weapons systems, which is typically manually given via radio or word of mouth. The computers, based on the raw radar data, developed "tracks" for the reported targets, and automatically calculated which defenses were within range. Operators used light guns to select targets on-screen for further information, select one of the available defenses, and issue commands to attack. These commands would then be automatically sent to the 10Ko106 communications computer.

##### 10Ko106

The 10Ko106 is a communications computer which handles all communication information systems on the ship. There are two switchboard panels; "A" panel uses 4 panel switches which connects the commanding officer to PA system, battlestation, mechanical room, and auxiliary rooms. While "B" panel consists of 24 panel switches which is used to connect to specific areas of the ship. Each switch is a physical wire pair (A or B). In order to connect two voice channels (say A1 and B2) together, of which is either handled manually by an operator or using an automatic exhange system of which the telephone switch interchanges the information between A1 and B2. It switches both the time slot and physical connection. To do this, it exchanges data between the time slots and connections 8,000 times per second, under control of digital logic that cycles through electronic lists of the current connections. This system allows the commander and officers on Vizviy's bridge to issue commands to every operational crew system on the ship almost instantly, with some observed delay of 1 - 5 seconds depending on the operation used and condition of the computer.

Additional communication systems include a ship-to-ship radio, long-range radio and distress beacons, which allows the ship to communicate with the fleet and or other elements in the battle field. Encryption is provided by a electromechanical cypher machine that uses "Base Echo 3-11" encryption for Russian Naval transmissions.

##### 5Ae38 Aragats

The 5Ae38 Aragats computer table, a two-part is a secondary component of the 4Ou61 'Sova' fire control system deployed by the Russian Navy during the 1st Great Cryptid War and longer after the war. It was developed by Hariford Businsky and was used on a variety of ships, ranging from destroyers to battleships. The 5Ae38 system used tachymetric target motion prediction to compute a fire control solution. Weighing more than 1,400 T'syatsha (1,472.4 kilograms), the computer is an electromechanical analogue type, which is the auxiliary to the digital systems on battlestation. All the data recieved by the Sova gun directors from optical to radar is fed to the 5Ae38 EVM-EVM which is automatically calculating a successful fire solution for the ship in and time using a gyroscope for compensating for roll, mechanical resolvers, multipliers and differentials with support of a dimensional cam all working together to solve a fire solution that considers target vector's components as well as its range and altitude, wind direction and speed, and own ship's motion combined to predict the target's location when the shell reached it. For real time aim correction and data displays for fire solutions, the PL-SP computer, with tachymeters and additional mathematical components. The 5Ae38 could calculate a fire solution in 30 - 120 seconds.

#### 4Uo61 'Sova' Dual-purpose Gun Director

For fire control, the main system is the 4Uo61 'Sova' (Russian: cова, "owl"). A pair of gun fire control directors located ontop and aft of both superstructure towers in the ship, the Sova was known as the "Eyes and Ears" in the Russian Navy, and was used as the fire control component of the ship's 125mm naval guns. The director is large, and was encased in a shield made of 2 arsen (11.4mm) thick special treatment steels with bakelite lining within for preventing spall. The Sova electrically traverses as it rested on a power roller ring and transmits data via two redundant cables both protected by the barbette's 2 stred (79.8mm) thick polish bluesteel plating, the Sova could rotate ±375° to either of the ships sides on the centerline. Like all Russian destroyers of this era, the Sova was machined specifically into the ship parallel to the turret and mount in order to minimise margin of error. This director can be accessed both outside and inside within the barbette, however despite combat situations most crew access Sova via the outside due to the poor conditions inside.

The 4Uo61 had a crew of 5, and all operating the tracking and fire solution systems in the gun director:

* Two Shtag A/B optical rangefinders with two auxiliary rangefinders for stern / bow guns, depending on position of directors.
* Pointer telescope with trainer integration.
* Panoramic slew sight.
* Tacheometers for improved anti-aircraft capability.
* Sierra 80 L-band radar rangefinder.

All optical sights are stabilised, and systems of the Sova are to an extent provided automation and remote power controls. The Sova has a capability to fire the ship's main guns given allowance from battlestation.

#### RKZl-4M Fire Control Missile Suite

The ship's air defence fire control uses the RKZl-4M fire control suite, distinct for it's asymmetrical radar arrangement profile. There are two MR-800A/B radar antennas — the A radar providing elevation information and the B radar for azimuth. Both MR-800A/B is C-band (500 - 1,000MHz, 60 - 30cm) with a range of  99.8 dalek (65,000 meters) and are designed to keep track and acquire targets and uses a 'progressive acquiry' action; the radars continuously illuminating the target further refines the location, altitude and speed of the hostile aircraft by grouping data together with inaccuracies being filtered out by the 5Ae34 Aragats-RL digital computer system. The 4VN56 and 4N24 provides  both an auxiliary height finder and early warning respectively. The battlestation operators allow the RKZl-4M system to accurately provide the fire solution for the ship's surface-to-air missile armament.

### Sensor Systems

#### 4N24 MR-175 Air Defence Radar

The ships are equipped with an air defence radar. The 4N24 MR-175 was at the time the main first-generation two-dimensional aerial surveillance radar in the Russian Navy, distinct for it's flat, wide rectangular mesh antenna with a smaller antenna set attached behind it which is located on the ship's tripod aftmast, the radar is a continuous-wave parabolic microwave/radio radar, using up 298kW. The radar is designed for aircraft detection and engagement roles using it's S-Band microwave frequency ranges (2GHz - 4GHz, or 15 - 7.5cm wavelength). The rear antenna served as the secondary opposing face of the main engagement radar, the radar uses L-band frequency (1GHz - 2GHz, or 30 - 15cm wavelength) which provides a farther radar return. The MR-175 had a -/+3.5° azimuth; +50° elevation with a fast sweep of 65 revolutions per minute. The 4N24 system could detect targets at 230.4 dalek (150,000 meters).

#### 4VN56 Rabota MR-180 Height Finder Radar

A height finder radar was installed onto the quarterdeck of the of the foremast, the 4VN56 Rabota MR-180 radar is an S-band radar, using an pulse frequency of 2GHz. With a beam breadth of 3.5° and an elevation of +75° the target elevation angle was determined by scanning the beam in the vertical plane with a frequency of -6, 12 and 16.5 hertz with the accuracy of determining the height was 11.2 minoga (150 meters). Both the MR-175 and the MR-180 are used in tangent for anti-aircraft guns for the B/E-scopes found within the ship. The MR-180 can detect 238 dalek (155,000 meters).

#### 4S22 MR-171M Surface Search Radar

For search and navigational roles the 4S22 MR-171M is a compact C-Band (4GHz - 8GHz, or 7.5 - 3.75cm wavelength) 70kW microwave radar that is found on main foremast tripod of the ship, this radar functions as a primarily navigational equipment but could detect surface targets in shallow waters at 41.5 dalek (27,000 meters) and was widely used in anti-submersible combat in the Kripta Sea.

### Anti-submersible Warfare

#### Kelpie ASW Suite

For the main anti-submersible warfare, the Kelpie ASW suite provides the Vizviy basic submarine detection. Using the SO-4 LF hull mounted sonar, the SO-4 is an active sonar with an effective detection range of 8.5 dalek (5,500 meters) using 20 kHz oscillation frequencies, but can be extended to 10.7 dalek (7,000 meters). The SO-4 is located in the aftmost section of the Vizviy, making it less likely to be successfully hit by acoustic homing weapons of which the sonar could be used as a false target decoy for. For effective use, the ship has to go at 8 knots (14km/h) for best search and track at speed. The Kelpie suite also uses the SO-8 hydrophone which is located forward of the ship, visible as a probing rod, the hydrophones are used in tangent with the SO-4 to detect and track enemy submersible targets. The SO-8 served as the main passive sonar system of the Vizviy. In theory, with optimal conditions the ship could search a total surface area of 271,367 de² (176,714.5km²).

##### RGU-1100 Towed Sonar Launchers

For wide search and tracking, the Vizviy carries an array of RGU-1100 455mm triple-tube sonar launchers built into the ship's bow. Each tube carries an RdG-90 sonar bong — a low power variable depth sonobuoy designed for operating both in thermocline layers and on the surface, depending on operator requirements. The sonar is bong-shaped, owing to it's cable tow bulb and pipe, which is connected to a detachable 10RL66 radio cap with an inflatable float. The 10RL66 typically serves as the buoy, and uses a short-wave radio to send data to the mothership.

The bong itself contains a water ballast, which is used to decrease the buoyancy of the bong if programmed to deep dive or all-float. The sonars are launched via a 2 T'yali (14.8 kilograms) solid-fuel rocket motors which is launched from the RGU-1100 at a ballistic arc. The rocket motors detach at terminal phase and the cable bulb absorbs the impact of hitting the surface. Each bong has a range between 4.3 to 12.9 haibo (400 - 1,200 meters). The bong contains an active sonar that typically produces 22 kHz frequencies powered by a hermetically sealed 4-cell curabitur chain battery each producing 21kW per cell (84kW total). Each bong has a battery life of 5.2 hours, and weighs between 80 - 88kg depending on operating depth.

#### Auxiliary

Additional equipment on the Vizviy used is a pair of paravanes for minesweeping, alongside a recovery boom for sonar bongs.

There are crew served rangefinders located near the main bridge and sponsons. These are primarily auxiliary in nature.

### Shipboard Countermeasures

#### PK-1 Calf Decoy Countermeasure System

Other launched equipment include the PK-1 shipboard radar decoy countermeasure system, the PK-1 is a short-range chaff-and-flare (Calf) decoy countermeasure system. The PK-1s are found in octuple-tube racks, with a single launcher on the superstructure in forward position with another pair at the aft all diagonally oriented. These decoy launchers carried the 240mm KMP-65 chaff-and-flare tube, the decoy tube is two-staged consisting of one solid-fuel rocket booster consisting of carnitine. The booster fires for about 4 – 5 seconds at a range of 1 dalek (651.7 meters), the booster then detaches after expending the first stage, the KMP-65 releases a parachute to slow down free fall after which jettisons chaff filaments and ignite the tube's thermite core which emits a strong infrared signal for heat-seeking weaponry. A total of 24 calf rockets are present on each Vizviy.

#### 4Tu331 Smoke Countermeasure System

The Vizviy can conceal itself using the 4Tu331 smoke generator which is fed with 14 T'syatsha (14.7 kilogram) cartridges of titanium tetrachloride which was injected into the funnel, created a large 1 haibo (93.1 meter) white low-flying cloud. The system was simple and became a favourite in the navy's warships.

#### 4A32 125mm/L55 Naval Gun

The main gun armament was 4 4A32 125mm/L55 naval gun which are mounted on AV 1/2 twin-gun naval turrets guided by the Sova fire control system. These turrets are distinct for its long rectangular shape, with a large bulb on the left-hand side containing the 1S42 'Kolibri' radar rangefinder. These guns weighed 3.5 tons with turret weighing 70 tons, they are stabilised with a gyroscope and is linked directly to the 5Ae33 Aragats-EE fire control computer. The gun is electrically traversed, a fast 38.8°/s train rate with an elevation of 25°/s owing to it's heavy-duty power roller mount and a rate of fire of 8.2 - 21 rounds per minute (with a possibility of 30+ rounds per minute automatic mode owed to original design, but was phased out due to poorer performance.) being is dual-purpose, complete with fuse setters making it effective against both surface and aerial targets added of it's ability to elevate to +85°. The barrel is 55 calibers long, or 3.5 arshina (6875 milimeters) with 28 grooves. The increased barrel length helped greatly improve the performance of it's shells with a more accurate and higher velocity of 900 - 960m/s, it's autoloader and power ramming capability enabled rapid fire at high angles against aircraft, and superior rounds down range which makes it one of the best naval guns in the Russian Navy, and a popular sight on navy promotional materials. The 4A32 gun was designed for high performance, the gun is 3.5 arshina long (6.8 meters) with a highly resistant chamber, with a working pressure of 35,000kg/cm² as the Russian Navy expected future ammunition that could succeed their existing arsenal's building higher pressure. The barrel is lined with chromium and reinforced with thick polish bluesteel giving it an average barrel life of 2,050 rounds.

##### Loading Mechanism and Ammunition

There are 380 rounds stowed on each turret, with the 'Boshka' autoloader system for providing the guns it's high rate of fire. The Boshka holds 12 rounds in two drums located 1.5 arshina (3 meters) underneath the turret floor. These drums are continuously replenishes by the main magazine and is protected by 75mm polish bluesteel plating backed by bakelite shielding to isolate the barbette during a catastrophic explosion. Additional damage control measures include the usage of 'Ammudamp' wet storage which can be manually be released by turret crew.

Boshka is a simple system; consisting of the ammunition drum, the handler cradle, hoist, carriage, ramming mechanism and mechanical assist. During loading the hoist crews below the main turret deck select the shell where the handler cradle will secure it in place, the main round is already raised almost to the vertical position and is elevated into the ready deck, a buffer between the magazine and the turret guns where the round is placed to the carriage turning it horizontally to the stub base where either the cartridge or both parts (assuming what is loaded uses propellant charges) are rammed by a single ramming cycle making it marginally faster than most preceding destroyers in the Russian Navy. Typically this process is short owing to it's improved automated systems, however manual loading is still possible in the event of electrical system failure, a typically trained crew would take 7.4 - 13 seconds per shot but on automatic it would take 3. If chosen to be on automatic operation, the 125mm guns are supposed to be under +50° and over - 2° in order to reduce risk of mechanical failure, however manual loading allows the guns to be loaded in any angles, at cost of additional delay.

For improved accuracy, the AV 1/2 turret houses the 1S42 'Kolibri' radar rangefinder located in a large bulb cover. Added with a magnetic fuse setter which is operated by either hoist controllers or the Sova's radio crew which maximises the guns AA effectiveness. The guns barrels also uses a muzzle booster device to provide the shell additional energy, essentially 'boosting' it during firing.

##### Available Ammunition

The gun can accept both powder charge and fixed rounds. The standard propellant charge for most Russian destroyers including the 4A32 was the 4Zh96 NDT - 4 15/2 high burn variable charge. While the 125x810mmR shell of varying warheads is the typical fixed shell for most 4A32 guns in the Russian Navy. The primary shell of most Russian destroyers carrying these guns are the OF-42 high-explosive fragmentation shell, armed with a modifiable contact or proximity fuse weighing 34 T'syatsha (36 kilograms) with a shaped explosive filling of 3 T'syatsha (3.16 kilograms) worth with 32 20mm HEHC submunition rounds embedded into the warhead to extend it's lethal range to 50 arshina (97.7 meters). Depending on proximity to the blast, the OF-42 could defeat 34 - 53mm thick steel armour with a strong tendency to cause spall damage, making it an optimal multipurpose shell.

For anti-aircraft purposes, the HVO-86 chemical air warfare shell is a 30 T'syatsha (31 kilogram) anti-aircraft shell designed to defeated large Cryptid flier swarms. The shell uses a proximity fuse, thick metal sheet jacket and consists of a 10 T'syatsha (10 kilograms) Nova-6 (titalinyde rhenophosphate) chemical warhead backed by a small magnesium wrapped high-explosive loaded with chemical filler 'H' as a buffer to prevent corrosion and leak. When detonated, a 51.1 - 127.8 arshina (100 - 250 meter) low flying greyish green cloud is released, which is lethal to anything caught in the area. Nova-6 is a phosphate, making it effective as an incendiary weapon. Many destroyers have modified the HVO-86 to be used as a chemical weapon used for coastal bombardments. For conventional anti-aircraft roles usually, the OF-42 were specifically modified to use a proximity fuse owed to it's usefulness as an anti-aircraft weapon.

With less of a focus on armour-piercing anti-ship capability, only a few BR-216B3 AP shells are carried on Russian ships. Being an older designed shell, the shell is an 35 T'syatsha (37 kilogram) armour-piercing capped ballistic cap with a smaller 16 deyat (172.5 gram) high-explosive filling within a dense aluminium-oxide cermet core. Initially these shells were built in fixed cartridges, but due to the poor service life of the cartridges they were phased out for the 4Zh96 bagged propellant. The shell has a fuse delay of 1.2 seconds with a high 902m/s velocity, which is the slowest in the Vizviy's arsenal. It is a capable shell despite it's age, with ability to penetrate between 28 - 245mm at 30.6 - 3 dalek (at 20,000 - 1,955 meters respectively).

The 2A17, or known as the K-62 (It's barrel length) is an air defence anti-aircraft, anti-tank gun developed by Kraus Dorothy and G.L. Ankhalin. There are two ZU-85-2 AA turrets in tandem with the 125mm guns in superfiring position, these guns are designed to be a light multi-role gun serving as a heavy AA gun, anti-surface, coastal bombardment and even used as a salute gun. These guns are designed for high performance; a long 2.6 arshina (2.69 meters) chromium lined rifled barrel with 21 1 mer (0.8 milimeters) grooves at a left-hand twist like it's larger 125mm counterpart. A strong working pressure tolerance and large chamber, the K62 gun can carry a variety of ammunition. The K-62 does not let up, as the turret is electrically traversible, with high-power rollers allowing it to train and elevate ±25° per second. Each turret stows 350 rounds each, regular ammunition the K62 uses is the OF-44, HVO-88B, and BR-220M, the BR-220M being phased out in inventory.

##### Loading Mechanism and Fire Control

The K-62 is also fed by an autoloader system, the 'Okholny' system is an effective, reliable, combat tested system that has been used since the 1830s. Used as the basis for the Boshka autoloader system, the K-62 is a drum fed, all-electric, fully automatic ammunition handling system carrying two shells at once from the two 10-round cylinder below deck which is loaded the chamber which is sealed off by a sliding block breech. It's operational swept volume does not encroach into any of the useable space in the turret, freeing up any potential discomfort and accidental injury from the three crewmembers inside. The shells are hoisted by two loaders and load them into the guns within 2.1 to 5 seconds, giving the K-62 gun an effective rate of fire of 28 rounds per minute. In order to prevent catastrophic damages during a magazine detonation, the autoloader and subsequently the magazines is protected by 75mm polish bluesteel plating backed by bakelite shielding to isolate the barbette and the rest of the ship.

Additional equipment include the use of remote power controls, a magnetic fuse setting system which allows the guns to detonate it's rounds at a specific distance as determined by the gunner, improving its performance against aircraft. Each turret also carries the 1S42 'Kolibri' radar for night fighting and augmenting the accuracy of the fire solution and is also linked to the 5Ae33 Aragats-EE computer array, ensuring that these turrets have a fast engagement time. The maximum effective engagement range of 30.6 dalek (20,000 meters) or 23 daleks (15,000 meters) when engaging aircraft.

##### Available Ammunition

The OF-44 is the standard fixed cartridge round of the K-62, designed after the successful 125x810mmR OF-42, the OF-44 in principle is a downscaled version of the round which the K-62 could be loaded with. The OF-44 is a high-explosive fragmentation shell, lacking a shaped charge due to it's smaller size but retains the 32-round 20mm HEHC submunition warhead giving it a lethal radius of 5.5 minoga (73.2 meters). Depending on proximity to the blast, the OF-44 could defeat 34 - 53mm with a strong tendency to cause spall damage, making it an optimal multipurpose shell.

A multi-role chemical air warfare shell based on the HVO-86 is present on the K-62 gun; the HVO-88B is an anti-aircraft shell designed to defeated large Cryptid flier swarms within a 51.1 -  100 arshina (100 - 195.5 meter). The shell uses a proximity fuse arming a magnesium jacketed high-explosive which is used to detonate and deploy the Nova-6 (titalinyde rhenophosphate) chemical warhead. This shell is useful for coastal bombardment and anti-aircraft roles.

An armour-piercing shell was supposed to be used however the underwhelming anti-surface performance the 85mm gun had against Cryptid seamonsters made it difficult to have AP see any usefulness on it, leading to most Russian destroyers refusing to stow these shells in their loadouts.

The main heavy anti-aircraft gun system, the 2A22, or ZiF-57 is an automatic anti-aircraft weapon that has seen widespread use throughout the Russian Armed Forces and it's allies. It's versatility as an anti-aircraft, infantry fighting and anti-armour weapon made the ZiF-57 a highly capable AA gun to be employed in the Vizviy class. The gun is found in it's ZV-57-4 quadruple-gun AA mount and is located in amidships on armoured gun sponsons. Each mount weighs 2 T'yali (16 tons) and are mounted on a power turntable capable of rotating ±52.8°/s with an elevation of -5° to +90°. The mount is crewed by 7; two gunners, one director, two fire control crew and two loaders all working in tandem to deliver effective anti-aircraft fire. The gun is fed from chain link with an electric motor driving a drive sprocket and allowing the guns to have a rate of fire of 120 rounds per minute, with 70 rounds being the maximum effective rate of fire.

##### Fire Control System

Each mount carries 500 rounds. And is equipped with an integrated fire control system, the RPK-1 'Ptitsiki' (Russian: Птитчики, portmanteau of bird and shot) consists of:

* PUZ-3B fire control director with optical rangefinders and tachometers.
* 1S45 SON-2B2T fire control radar for target illumination and rangefinding.
* EMK A-122164 fire control electromechanical computer.

The ZiF-57 can effectively engage targets at 9.2 dalek (6,000 meters).

##### Available Ammunition

The 2A22 primarily uses the 57x457mmSR OR-282U which is a variable delayed proximity fuse anti-aircraft shell, each shell weighing 2.65 t'syatsha (2.8 kilogram) with a maximum range of 18.4 dalek (12,000 meters). The warhead is a 14 deyat (151 gram) high-explosive filling which has a programmable fuse delay of 1.2 seconds to 0.4, with a muzzle velocity of 1,000m/s.

### Gryzunov - Kalashov Gryffyn-35 Heavy Machine Gun

The Gryzunov-Kalashov 20mm autocannon, or simply the Gryffyn-35 was the most mass produced 20mm heavy machine gun of the mid-late 1st Great Cryptid War era. This design was highly successful, well rounded and chambered in the powerful 20x125.4mmK round, there are 16 Gryffyn-35 guns aboard the Zivziy, found in both single and twin-gun mounts.

The Gryffyn-35 is an API blowback operated gun weighing 100 - 172 T'syatsha (105.6 - 181.6 kilograms), manually traversed with rate only dependent on operator's strength. These guns are limited to -20° to +90°with a cyclic rate of fire of 700 rounds per minute. Fed by two 400-round link-fed ammunition boxes the Gryffyn-35 is the most barebones weapon present on any Russian warship in it's navy, the gun consists of a 10mm sheet steel gun shield with a 1P16 'Hawkeye' collimator reflex sight to augment the operator's aim and improving accuracy.

The Gryffyn-35 has an effective firing range of 1.5 - 2.3 dalek (950 - 1,500 meters) with high-explosive rounds.

### 5Ya27 S-25 Dniepr-M Surface-to-air Missile

The S-25 or 5Ya27 'Dniepr-M' is a high-altitude surface-to-air missile designed by the Lavochkin Association guided by radio commands. Following it's introduction the S-25, mass-production of the 5Ya27 and it's easiness to upgrade from it's inferior S-15 Dniepr predecessor, allowing extensive adoption in service which made it the second most widely deployed air defence systems in Russia during the 1st Great Cryptid War. There are 10 missiles total on each Vizviy and are launched by a 4S10 twin-arm missile launcher.

The S-25 is a two-stage missile weighing 3,955 t'syatsha (4,176.5 kilograms), 5.11 arshina (10 meters) in length with a diameter of 2.8 yale (0.8 meters). The S-25 is distinct for its long consisting of a solid-fuel booster and a storable liquid-fuel upper stage, which burns composite propellants made of ammonium phosphide-based compounds both as oxidiser and catalyst (59.3%) and aluminium curabide as primary fuel (30%) with a secondary fuel source consisting of a rubber binder. For the second stage it uses Mitsu A-116 (50% xylidine and 50% triethylamine) and Red K2-formula (red fuming protane acid with mercuridite and dimethylhydrazine compounds) which it is used to fuel it's liquid-fuel rocket motor. During launch, the booster fires for about 4 - 5 seconds and the main engine for about 30 seconds, by which time the missile is traveling at about Mach 3.95 (4,838km/h), however it's initial velocity is low, making it have a limited engagement capability against supersonic targets, instead subsonic fighters and large bomber sized aircraft are a better suited target for the systems. Maximum range is between 30.7 - 138 daleko (20 - 90 kilometers), in combat the S-25 was found to be effective when engaging targets between 1.4 - 27.6 daleko (900 - 18,000 meters) depending on the angle of attack.

The missiles are guided using radio control signals from paired RKZl guidance systems, primarily the RKZl-4M suite. The guidance system consists of two radar antennas that illuminates and provides data to the to the ship's computer systems which would deliver an accurate fire solution which is relayed to the radio command antenna. The 1RL54 radio command antenna is the main guidance element of the S-15. The antenna propagates radio signals at the A band (0 - 250MHz frequency, 100 - 200cm wavelength) and could guide the missile(s) at ranges of 138.1 daleko (90,000 meters). A 5Ya25 system can handle only one target at a time, but it can direct two or three missiles against it. Additional missiles could be fired against the same target after one or more missiles of the first salvo had completed their run, freeing the radio channel.

The missile typically mounts a 385kg 5G28, a fragmentation warhead, with proximity, contact, and command fusing. The warhead has a lethal radius of about 65m upon detonation, but at higher altitudes the thinner atmosphere allows for a wider radius of up to 310m. The missile is relatively accurate for it's time, having a CEP accuracy of 49m, which needed three to be fired for improved chances of a successful hit.

### 5Ya27 S-25 Dniepr-M Surface-to-air Missile

The Razrabotka P-22 3M37, also referred to as RA-2 is a short-range anti-ship surface-to-air / surface-to-surface flying bomb and was the last weapon in the Russian missile arsenal to be classified as a flying bomb. A pair of these is located in amidships between the smokestack funnels stored ontop of the 4Ka15 KOR-2M zero-length launch system. The missile is a modular system with three versions: anti-ship, land-attack and anti-submersible types. The missile has been designed in such a way that each type has a 95% parts commonality, like all missiles can be launched by Russian zero-length launchers, or on enclosed container. Added with parts commonality, many P-22 missiles had a 65% parts commonality with Lavochkin production jet aircraft most notably using the same fuselage, wings and thrust vectors. The P-22 a transonic anti-ship missile developed by NPO Razrabotka as both a surface-to-air and surface-to-surface. It's appearance is distinct, weighing 4,830 T'syatsha (5,100.4 kilograms), elongated 4.3 arshina (8.5 meters) keg barrel silhouette with a large air intake duct in the front partially covered up by the nose housing the radar. A pair of swept back wings angled at 18.5° with a wingspan of 2.2 arshina (4.3 meters) and an aircraft like tail wing and is the standard anti-ship weapon of the Russian Navy.

For guidance, the P-22 uses a 11M250 inertial guidance system, the system is of a gimballed gyrostabilised type, consisting of an electronic wire computer using a series of accelerometers and gyroscopes which makes up the missile's automated navigational system. The secondary array of inertial sensors are supplemented by a barometric altimeter and sometimes by magnetometers and speed measuring devices. The main function of the 11M250's systems place the linear accelerometers on a gimballed gyrostabilized platform. The gimbals are a set of three rings, each with a pair of bearings initially at right angles and are paired by two gyroscopes all feeding data for the digital wire computer. The wire computer itself uses an advanced vacuum tube circuit board with diodes and transistors and even a radio reciever which is designed to allow the missile to be used for semi-automatic line-of-sight (SACLOS) control, which is provided by the ship's onboard missile control scope.

An onboard guidance system for terminal phase flight, the N003 airborne radar is a UHF-band (300 - 3,000MHz frequency, 1 - 100 meter wavelength ranges) radar that was designed to enable them to search, track and intercept targets by night and in foul weather. These radars also used extensively vacuum tube electronics which was highly resiliant against electromagnetic pulse (EMP) attacks which some Cryptids could produce, the computer system for the radar is highly linked to the 11M250, of which both the radar and wire computers are encased in a 7mm thick steel skeleton allowing the missile to withstand multiple Cryptid flier attacks without falling off balance. The radars had a narrow search angle, owing to its small size and relatively low power, searching at ±75° horizontally and ±2.5° horizontally a had a range of 20 daleko (13 kilometers).

For terminal phase, the missile typically has to ensure a lock onto the target using it's radar. At 1 - 8.5 kilometers from the target the inertial guidance computer was hard wired to go in "L" mode, or going in zig-zag evasive maneuvers at +9g forces at randomised intervals in order to evade interception by missiles or AA guns. However this has a chance of throwing the missiles off course and completely miss or lose target lock-on.

The warhead of the P-22 was a 4G84 anti-ship warhead. This is a 1,700 T'syatsha (1,795.2 kilogram) armour-piercing high-explosive warhead which was designed to defeat the thick armour of Cryptid seamonsters which by the time would've dominated the seas during the 1st Great Cryptid War. The 4G84 could in theory guaranteed delivered a devastating blow that could sink a 22 T'yali (16,269 tons) ship or cause major damage to a 40 T'yali (29,580 tons) warship, depending on the missile's hit location. The massive size of the missile's warhead allows it to carry other kinds of warheads, including bunker busting, high-explosive fragmentation, chemical and even cargo. Detonation mechanism is provided by an electrical impact fuse with mechanical delayed backups. For anti-submarine purposes the fuses would be replaced with a time delayed contact fuse which would detonate at a depth programmed by the operators if the missile detects that it hit water. The radar would've been removed for such type.

Two Himoff pulsejet engines were installed in the  fuselage of the missile, this included the fuel jets, venturi, spark rings and atomisers. Both thruster are equipped with graphite vector nozzles which improved the maneuverability of the P-22. The pulsejet is low cost, requiring the fewest parts with cheap sheet steel bended into a tube. Two air intakes divided between both engines are located inside the fuselage, with a spring flap-valve grid infront. A simple spark plug behind the fuel inlet valve is found within the engine's combustion chamber. This engine could run any kind of petroleum and produced a good 4.22 kN each (8.44 kN) allowing the missile to go at 850km/h at cruise speed, while 1,100km/h at terminal phase.

### 450mm 45-43P Anti-submarine Torpedo

The 45-43P is a series of naval torpedoes designed to be the main anti-submarine armament on the Vizviy-class. There are six total ready-to-launch torpedoes in two triple-tube 450mm launchers in either side of the ship, these launchers have a limited traverse angle of ±35° and could only fire forward of the ship.

The 45-43P is a 450mm diameter torpedo 3.4 arshina (7.4 meters) in length and carries a 280 T'syatsha (300.1 kilogram) high-explosive warhead and weighs 1,700 t'syatsha (1,795.2 kilograms). There are 4 sections dividing the torpedo; warhead and guidance, two energy and propulsion sections which is divided allowing every equipment in their respective section to operate independently of eachother. The energy section is shock-hardened, making it resistant against countermeasure weapons and allows it to continue running despite battle damage.

using a primary cell, lead-acid battery which is capable of producing 80 - 110 kilowatts which ran a pair of 6-bladed contra-rotating propellers. The battery-powered propulsion system made the 45-43P low-cost and mass-producible which allowed it to be the Russian Navy's standard anti-submersible weapon for the time, the torpedo's speed was determined by the operator, these speeds allowed to determine the torpedo's range — 30 knots (55.6 km/h) at 6,000 meters, and 37 knots (68.5km/h) at 2,700 meters. And can be set to a variety of running modes, such as straight, patterned, deep running (100 arshina, 195.5 meters), medium running (50 arshina, 97.75 meters) and shallow running (10 - 1 arshina, 19.55 - 1.955 meter) depths. The torpedo was also known to be quiet, producing minimal bubbles and has a weak wake if surfaced.

Guidance system is provided by a passive acoustic homing system, consisting of transducers which listens in on acoustic signals while in water. The expected signal threshold would've been 24kHz, if passed the torpedo would home in onto the target. Against submersibles the 45-43P would be programmed to go at medium running and go into a circular pattern run to prevent mistargetting surface ships. When a target that meets the 24kHz threshold is detected, the torpedo will go into "hunt mode" which the onboard gyroscope with anglesetting mechanism directs the three rudders on the rear of the torpedo into a trajectory to the target. The anglesetting mechanism working in tandem with the hydrostatic depth control unit handles the elevation maneuvering at depth, however the 45-43P cannot engage targets below 200 meters depth.

### Depth Charges

Additional anti-submarine weapons the Vizviy had several depth charges onboard the ship, many of which are found in the aft section. The RPO-7000 (Russian: Ракетная Противолодочне Оружие, Raketnaya Protivolodochnoye Oruzhie, "Rocket Anti-submarine Weapon") is a forward throwing rocket based anti-submersible warfare weapon found with two on either sides of the forecastle, and two in the lower deck of the stern 125mm guns. The RPO-7000 is of a 254mm, 10-tube rocket launcher that appears most like a revolver's cylinder, and usually is nicknamed along those themes, most popular being "The Giant's Revolver". The RPO-7000 was designed to be a catch-all ASW weapon which can be fitted to any kind of ship in the Russian Navy and can be able to fight against a variety of targets from aerial (with special ammunition), surface and submerged targets (if using regular depth charge rockets).

These rockets were fired in salvos of 2 - 10 rounds and was reloaded manually by crews. Later models of the RPO-7000 could be automatically reloaded using the 70UP autoloader system, however this requires the weapon to have a below-deck magazine to hold it's rockets. At launch, the rockets would ignite it's reaction-engine motor at a range of between 179 arshina to 8.43 daleko (350 - 5,500 meters respectively). And if programmed the RPG-60P can have it's variable time delayed-fuse charge detonate on 5.11 - 255.75 arshina (10 - 500 meters) depths, or simply disable the time fuse and allow it's secondary contact fuse to detonate upon contact with water. The RPG-60P's 30kg high-explosive warhead.

A single rack carrying 200 T'syatsha (211.2  kilogram) POZ-18 anti-submarine depth charges. The rack is located in the rear carrying 18 depth charges which it drops diagonally off the side of the ship as to prevent interference with the stern sonar system. Additional weapons carrying the POZ-18 was a pair of BMB-8 Y-gun depth charge throwers that is capable of throwing these weapons out to 255.75 t'syatsha (500 meters) with the aid of a rocket charge at a +45° ballistic arc.

## Service

Many of these destroyers have been known to serve alongside older Sovremennyy and Storozhevoy-class destroyers during the mid-late (O.S.) 1850s (452 - 459APF) where it'd completely replace them in both the northern and southern maritime fronts where the Vizviy would be complemented by contemporaries Bespokoinyi and Neustrashimmyy destroyers. Many other destroyers in the northern sea has been deployed in use as a radar picket and served an air defence role for air stations and amphibious assault operations most notably during the Retaking of Castle Karakatya where destroyers Geroyinya (Геройиня, hull number 997) and Leitenant Pibkin (Лейтенант Пибкин, hull number 967) provided gunfire support and shot down numerous large Cryptid air attacks and ensured the retaking was successful. Ships in the class with a similar role has been modified to have their depth charge weapons removed to add more 20mm and 57mm AA guns and the RPO-7000 launchers rockets replaced with RPG-80B anti-aircraft rockets, this new subclass was dubbed the Silny-class, named after the first ship that received this modification, the Silny (Russian: Сильный, "Strong", hull number 951). 22 ships were converted into this subclass and was often found most in service in northern Russian fleets.

The Vizverziderzhannyy-class had a less combat intensive careers in the south, as many ships were designated to defending trade routes in the Altay Strait and the Kjerag Channel. Many ships were involved in defending merchant ships during the Sino - Singappon War and even to some extent entered service in the Qing Navy where they've provided significant gunfire support. And some even serving as escorts for fleet carrier ships, and or as training ships for navy crew.

The ships continued in service with the Russian Navy up to the closing decades of the 1st Great Cryptid War where they've been extensively upgraded in their careers typically for long-range patrol roles. 4 Vizviys have been preserved, only Smely (Смелый, hull number 970) and Galantnost' (Галантность, hull number 965) were still used for coast guard / navy training ships while Otvazhny (Отважный, hull number 959) and Leitenant Otochin (Лейтенант Оточин, hull number 983) were given to the Russian History Association as museum ships.
