== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Soviet self-propelled anti-aircraft vehicle {{Battle-rating}}. It was introduced in [[Update 1.43]].

An SPAA built on a heavily-modified T-54 chassis, the ZSU-57-2 features two powerful 57 mm guns, good mobility, and very light armour. It has proven to be more of a menace to ground vehicles than aircraft with its high-velocity cannons, but low sustained rate of fire and poor accuracy.

{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=739|rbMinHp=460}}

The ZSU-57-2's mobility is rather good. It is faster than most medium tanks, while weighing 28 tons and having a 520 hp engine at 2,000 RPM. Manoeuvrability is good at all speeds, as its a relatively light tank with a powerful engine. It bleeds a lot of speed while turning, but the turning is fast and responsive and does not have neutral steering. The maximum speed is limited by the transmission to 51 km/h forwards and -8 km/h in reverse for RB, and 55/-9 km/h for AB.

{{main|S-68 (57 mm)}}

Although this is an AA vehicle, its twin 57 mm cannons are still equally deadly against ground units. When stock, their accuracy isn't good so the shells fly all over the place as the distance increases, and the belt is made up of half AP, half HE, meaning it is not efficient when dealing with either planes or tanks. Therefore the best tactic for a fully stock ZSU-57-2 is to shoot the enemies' side up close or to target low-flying helicopters.

When the BR-281 belt (full APHE) is available, the player can go into full anti-tank mode as this shell packs quite a punch, and it can penetrate pretty much any tank's side armour (excluding the Maus, in which case take out its gun barrels) and some tanks' frontal armour. In a flank the ZSU-57-2 can finish off a group of opponents at an unbelievable speed. Two shells will slice through their side armour and explode, so theoretically one clip is enough to wipe out four tanks in a row (aiming at the crew compartment only, of course). A few seconds later, another clip will be loaded, ready to hunt more prey. Be aware that each clip only contains 8 rounds (4 for each of the two cannons), so do not waste your shots.

This shell also performs alright in the AA role, since its calibre is quite large for planes, and a direct hit usually critically damages the plane, if not killing it instantly. However, unlike its Chinese brother, WZ305, the ZSU-57-2 does not have access to any VT shells so it is always beneficial to lead with extra care and only open fire if the plane is close enough.

==== Ammunition ====

* '''Default:''' {{Annotation|HE*|High-explosive fragmentation (self-destroying)}}{{-}}{{Annotation|APCBC|Armour-piercing capped ballistic capped}} - Half the rounds in this belt are useless against tanks or planes. However, against other SPAA this belt can reliably take out crew, armament, ammo and engine. Having one belt in reserve can help.
* '''BR-281SP:''' {{Annotation|APCBC|Armour-piercing capped ballistic capped}} - An anti-tank belt, it is comprised of APCBC shells that can penetrate most tanks from the side. However, the shells do not contain any explosive filler, so it is recommended to upgrade to the BR-281U belt when possible.
* '''OR-281U:''' {{Annotation|HE*|High-explosive fragmentation (self-destroying)}} - For use against planes. One or two hits usually gets the job done. Heavy armoured attackers and bombers may require more though.
* '''BR-281U:''' {{Annotation|APCBC|Armour-piercing capped ballistic capped}} - Very similar to the preceding BR-281SP belt; however, the shells now have a small amount of explosive filler, making them slightly more efficient against ground vehicles.

== Usage in battles ==

Versatile in the anti-aircraft and anti-tank role this heavily modified [[T-54 (1947)|T-54]] chassis delivers two heavy 57 mm punches. The ZSU-57-2 can be used for two roles.

;Anti-air role

Even though the ZSU-57-2 was designed as an SPAA, it is not very good at destroying planes compared to other SPAA vehicles at similar battle ratings, which often have a significantly higher rate of fire or even radar. However, this is compensated for by its comparatively massive firepower compared to similar SPAA platforms. The large 57 mm cannons will often disable, or more likely destroy a plane with its first hit. It is also extremely effective in an anti-helicopter role, as helicopters are much slower than planes.

;Tank Destroyer

Using the 57 mm cannons in an anti-tank role is possible and have been exploited by many players. Using BR-281 ammo, the guns can effectively pierce the sides and rear of any tank (excluding the Maus). Remember the ZSU-57-2's armour does not compare to other tanks armour so one shot could be the end of the SPAA. Play cat-and-mouse and wait for the enemy to go into an engagement with another target and then jump out into the open and fire upon them while they are distracted. It is recommended to the first aim for their rear to disable their engine and cause a fire, they will have to stop what they are doing and put it out. During this time they won't be able to move or fire upon the ZSU-57-2, allowing a chance to finish off the crewmen inside by unloading the 57 mm cannons into the side of the enemy tank. Any shot from the 57 mm cannons into an enemies' ammo load will also instantly kill them. Almost all British tanks have very weak side armour, and your BR-281 ammo will easily rip through even at an angle. Aim for the front portion of their tank, where their driver is. Their ammo rack is located right next to the driver, meaning that you can easily ammo rack them.

'''Fighting the ZSU-57-2'''

If you spot a ZSU-57-2, do not ignore it. It is a very real threat and can make short work of you side armour. If you have the advantage of surprise, aim for the turret, as this has a chance to take out the gunner, cannon breeches and detonate the ammunition. If none of these are destroyed with the first shot, retreat quickly, unless you are sure that the 57mm guns cannot penetrate your frontal plate. If you do not have the advantage of surprise and have less than 151mm of frontal armour including weak spot, do not peak out. Try to disengage. If this is not possible, call artillery fire on the ZSU's location, and/or mark their position on the map for better positioned teammates to deal with.
=== Pros and cons ===


'''Pros:'''

* Multi-role weaponry able to fight both planes and tanks
* Excellent turret rotation speed
* 57 mm guns will destroy or cripple aircraft with one hit, and can easily take out tanks from the sides too
* Very high penetration for an SPAA at 151 mm
* Very effective against lightly armoured vehicles like the [[Leopard 1]] or [[AMX-30]]

'''Cons:'''

* Large vehicle size
* Very vulnerable turret (ammo on all sides of turret + very thin armour)
* Crew is very crowded in the turret (1 shot has the potential to knock out 5 crew members with ease)
* Shells have bad accuracy after consecutive shots
* Sub-par anti-air capability due to low rate of fire and poor accuracy

== History ==

===Development===
The course of World War II revealed to the Soviets how dangerous the air power has become to their ground forces. It was determined that the best method of fighting these aircraft was to have ready vehicles in the front-lines with dedicated anti-aircraft roles to take out these assault aircraft. Experiences from other countries, such as the United States with their [[M3 Half-Track (Family)|M3 half-tracks]] equipped with anti-aircraft armament and Germany with their [[Wirbelwind]] and [[Ostwind]] anti-aircraft vehicles showed that the role of the self-propelled anti-aircraft gun (SPAAG) makes a positive effect on the battlefield for the protection of the ground forces. The Soviet development of SPAAGs came as simple, truck-mounted weapons and armoured variants of SPAAG were scarce to begin. The first put into production was the [[ZSU-37]], which did not see the majority of World War II as it was put into production on February 1945, with production lasted only until 1948 and retired not long after that. The single 37 mm gun on the ZSU-37 was also reported on no longer being efficient against aircraft, so a major development project was initiated for a new SPAAG in Soviet service.

Few projects were started on the SPAAG concept following right after World War II. One was just a [[BTR-152A|BTR-152 armoured personnel carrier armed with two or four 14.5 mm KPV heavy machine guns]]. About two different vehicle development was made for the SPAAG role, designated the ZTPU-2 and ZTPU-4. Development, while slow at first, took up a large focus after the realization that the Soviet Union's enemy, the United States, posses a large air force power that could take the air supremacy of the battlefield anywhere. This causes the Soviets to begin investing in a SPAAG in order to fight against this. The first of such was in February 1946 where the design bureau at Works No. 174 at Omsk along with Research Institute No. 58 at Kaliningrad submitted their joint design of a SPAAG based off the [[T-34 (1942)|T-34]] chassis. The design had four 37 mm AA guns attached, but the design did not proceed as new tank production at the time had the High Command prioritize on the new tank chassis that was going to be produced.

Research Institute No. 58 during this time developed a twin 57 mm anti-aircraft gun under the guidance of Vasiliy G. Grabin. The 57 mm gun was based off the previous 57 mm S-60 gun from 1947 and the new one was called the S-68, which was ready by 1948. This armament is then chosen to be mounted onto the new SPAAG project currently known as ''Object 500'', but the designation for such vehicle would be called '''ZSU-57-2''' ("57" for the armament calibre and "2" for the twin armament). The project design finished in 1948 with the S-68 gun mounted onto the new [[T-54 (1949)|T-54]] tank chassis. The first prototype was completed in June 1950 and testings for the vehicle lasted from 27 January 1951 to 15 March 1951, which had the vehicle drive 1,500 km and fire 2,000 rounds. More prototypes were built for testings and had improvements built into their design such as more ammunition storage. Service update tests started in 1954 after much delays in deliveries of the S-68 guns and parts for it, but the ZSU-57-2 was finally put into service on 14 February 1955. First vehicles were completed by 1957 and a total of 2,023 ZSU-57-2s were completed by the time production ended at the end of the 1950s.

===Design===
The ZSU-57-2 used a modified T-54 chassis for its basis, the T-54 chassis uses four road wheels per side rather than five and uses thinner armour. However, the interior is nearly the same as the T-54, with more space due to the thinned armour. There are three crew compartments in the tank, the driver in the front, the fighting in the middle, and the engine in the back. The driver's position has been moved slightly forward and to the left and has accommodations for an infrared vision device. The vehicle has a maximum road speed of 50 km/h and is considerably much faster than the T-54 due to the lighter weight while still powered by the same V-54 4-stroke diesel V12 engine.

The fighting compartment uses an open-topped turret that mounted the dual 57 mm S-68 gun. The gun is aimed via a sighting system that is adjusted based on the target's speed, direction, and range by the sight adjuster crew member. While the speed and direction must be estimated, the range can be found via a rangefinder or estimated. Two loaders are needed to load the two gun and a gunner fires using a trigger that fires both barrels or one of the two-foot pedals that fire either barrel independently. The gun is able to reach a firing rate of 240 rounds per minute with, but the practical rate of fire is about 140 rpm to maximize the barrel cooling rate and firing sustainability. Shells available for the gun are fragmentation and armour-piercing tracer, the fragmentation comes with a safety-destructor that causes the shell to explode after a certain amount of time so the rounds do not come back to the surface and do harm. The 57 mm shells were considered to be the most powerful anti-aircraft armament at the time and can very quickly destroy an aircraft if a shell connects.

A huge disadvantage of the ZSU-57-2 was the lack of fire-control radar, so it must rely on optical vision in order to find and eliminate targets. A ZSU-57-2 battery of four vehicles was less effective than a battery of six towed 57 mm S-60 anti-aircraft guns due to the latter having a fire control radar. The reliance on radar has been due to the increased proficiency of jets, which makes an estimation of distance and speed a very difficult process. Other disadvantages were its low firing rate due to the manual loading by loaders per gun, the air-cooled barrels heated up too quickly, and the turret traverse could not keep up with the newer and faster jet aeroplanes as well.

===Combat usage===
Entering service in 1955, the ZSU-57-2 replaced the older BTR-40As and BTR-152As in 1957 and was revealed to the public in November 1958 during a military parade. The ZSU-57-2 was issued out to tank regiments in one battery, which contained four ZSU-57-2s. This was later changed to two batteries per regiment, increasing the number of SPAAGs available. Some ZSU-57-2s saw service in motor rifle regiments as well as one battery. Despite its superior armament, the ZSU-57-2's performance among the newer aircraft technology along with jets causes the ZSU-57-2 to be considered unsatisfactory and obsolete by the early 1960s but stayed until the early 1970s as it was replaced by the [[ZSU-23-4]] Shilkas, which has radar-guided abilities. The remaining ZSU-57-2s were put into reserves, stored, repurposed into other roles, or scrapped.

Like much of the Soviet hardware, the ZSU-57-2 was also given out to the Soviet allies in the Warsaw Pact. Countries that bought the ZSU-57-2 range Poland, East Germany, Hungary, Bulgaria, Romania, Cuba, Egypt, Iran, Iraq, Syria, North Korea, and North Vietnam. These countries used the ZSU-57-2 to a greater extent than the Soviets did. East Germany was the first foreign operator to own the ZSU-57-2, which received 129 vehicles. Poland also received 129 units as well. Yugoslavia ordered 100 units, Slovenia owned a few for the 44th Armoured-mechanized battalion, Finland imported 12 units, and Cuba received 25 units during the missile crisis in 1962. Iraq, Iran, and Egypt ordered 100 units for deliveries, their use in conflicts would also end with the Israelis owning a few as well. North Korea developed its own units by using the Chinese Type 59 (a copy of the Soviet T-54A) tank chassis and bought the turrets to mount on them, about 250 were made like this. China created a copy of the ZSU-57-2 for Iraq by their request, using a reverse-engineered turret on a Type 69 chassis, which became the [[WZ305|Type 80 SPAAG]], though China is more well known for modernizing the S-68 ammunition with a proximity-fuze round.

The ZSU-57-2 saw use in many Cold-War conflicts in the hands of foreign operators. It saw action in the Vietnam War by the North Vietnamese and was used as air defence for tank regiments and against ground targets. The ZSU-57-2 also saw conflicts in the Middle East such as in the Six-Day War and Yom Kippur War against Israel by Syria and Egypt. These were used to defend the El-Arish airstrip, but they were not very successful and many were captured by the Israelis. Syria also used the vehicle again in the Lebanon War of 1982 against Israel, where they failed against the Israeli air force, but fair much better against ground targets. Iraq and Iran used the ZSU-57-2 against each other in the Iran-Iraq War, though Iraqi forces had access to Chinese copies and the benefit of radio information for their vehicles. Iraqi ZSU-57-2s also saw use in the Gulf War against the United States coalition where it manages to successfully shoot down a Tornado GR1 aircraft by the British, three more were reported to be heavily damaged as well. The Iraqis still used them up until the Second Gulf War. The ZSU-57-2s were used by many factions in the Yugoslav Wars and had air defence roles against the NATO air raids. The most recent usage of the ZSU-57-2 is in the Syrian Civil War, where 10 are still active in the Syrian Army, these are probably used exclusively against ground targets today.

In 1947 at the NII-58 research institute plans were made under the direction of B.G. Grabin to pair a 57 mm automatic cannon with a C-68 anti-air cannon on the basis of the C-60. It was intended to be installed on either a track-based chassis or a body with wheels.

The track-based chassis was based on aggregates of the T-54 medium tank. The self-propelled version of the vehicle received the factory designation of Object 500 and the military designation of ZSU-57-2.

The ZSU-57-2 underwent comprehensive testing from 1950-1954. In 1955 the ZSU-57-2 was accepted into the arsenal of the Soviet Army. It was produced at factory #174 in Omsk from 1955 to 1960. A total of 857 ZSU-57-2s were produced.

== Description ==

In November 1960, Finland ordered 12 [[ZSU-57-2]]s from the Soviet Union to replace the ageing [[L-62 ANTI II]]. This allowed for 6 anti-aircraft vehicles per tank brigade, and they were delivered along with 60,000 HE rounds and 10,000 AP rounds, as well as a number of [[T-54 (Sweden)|T-54s]], between 1960-1961. However, they were found to be severely limited by their inability to operate at night, and were eventually replaced by the [[ItPsV 90]]. The vehicles were withdrawn from service completely in 2006.

Introduced in [[Update "Fire and Ice"]], the ZSU-57-2 features two powerful 57 mm guns, as well as a heavily-modified T-54 chassis giving it good mobility but very light armour. It proves to be more of a menace to ground vehicles than aircraft with its high-velocity cannons, but low sustained rate of fire and poor accuracy.

During this time they won't be able to move or fire upon the ZSU-57-2, allowing a chance to finish off the crewmen inside by unloading the 57 mm cannons into the side of the enemy tank. Any shot from the 57 mm cannons into an enemies' ammo load will also instantly kill them. Almost all British tanks have very weak side armour, and your BR-281 ammo will easily rip through even at an angle. Aim for the front portion of their tank, where their driver is. Their ammo rack is located right next to the driver, meaning that you can easily ammo rack them.

'''Fighting the ZSU-57-2'''

If you spot a ZSU-57-2, do not ignore it. It is a very real threat and can make short work of you side armour. If you have the advantage of surprise, aim for the turret, as this has a chance to take out the gunner, cannon breeches and detonate the ammunition. If none of these are destroyed with the first shot, retreat quickly, unless you are sure that the 57mm guns cannot penetrate your frontal plate. If you do not have the advantage of surprise and have less than 151mm of frontal armour including weak spot, do not peak out. Try to disengage. If this is not possible, call artillery fire on the ZSU's location, and/or mark their position on the map for better positioned teammates to deal with.

=== Pros and cons ===


'''Pros:'''

* Multi-role weaponry able to fight both planes and tanks
* Excellent turret rotation speed
* 57 mm guns will destroy or cripple aircraft with one hit, and can easily take out tanks from the sides too
* Very high penetration for an SPAA at 151 mm
* Very effective against lightly armoured vehicles like the [[Leopard 1]] or [[AMX-30]]
* Guns will sometimes even manage to penetrate the frontal plates of mediums and heavies at the same BR

'''Cons:'''

* Large vehicle size
* Very vulnerable turret (ammo on all sides of turret + very thin armour)
* Crew is very crowded in the turret (1 shot has the potential to knock out 5 crew members with ease)
* Low turret walls allow for taller vehicle (especially ones with roof-mounted machine guns) to gun down the crew inside.
* Shells have bad accuracy after consecutive shots
* Sub-par anti-air capability due to low rate of fire and poor accuracy

M53/59

2024-04-11T05:37:01Z

U89914728: /* Pros and cons */

{{Specs-Card
|code=ussr_m53_59
|images={{Specs-Card-Image|GarageImage_M53-59.jpg}}
}}

== Description ==

The M53/59, known as '''Praga PLDvK vz. 53/59-"Ještěrka"''' (Praga twin-cannon AA Model 53/59 "Lizard") in Czech, is an ex-Czechoslovak SPAA built from the chassis of a Praga V3S truck with a pair of 30 mm ZK453 autocannon onboard. Although this truck was designed and manufactured by the dawn of supersonic jets, these 30 mm cannons did provide devastating firepower against light targets where it would be hopeless against autocannons. The truck didn't see action in Czechoslovakia (and their successor states) but combat records in both South Europe and Africa still reflect its combat capability at support fire operations.

One of the newcomers of the [[Update "Sky Guardians"]] and part of the Soviet tech tree, it not only doubled its firepower over its Soviet counterparts, but also has a high rate of fire against any possible aerial targets or armoured targets which happen to show their sides. It has more than enough penetration at its rank to tear them down with ease; but players would still have to conserve ammo as 100 shells per load (50 per magazine) with a rather long reload time could possibly be a death sentence to the truck if the enemy has the means to take you down with ease (i.e. HMG, other autocannons or HE shells). Sneak up and flank unaware enemies or find a spot and conceal yourself, then unleash bullet storm upon them when they show their sides.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

The M53/59 is based on a Praga V3S 6x6 truck with a revised cabin to crew 4 out of the 5 of them (with only a gunner outside); surprisingly, although only covered by 10 mm of steel at front, it could deflect .50 HMG from some distance or at flat terrains thanks to its angular design with slopes; the engine block could also absorb some damages but prolonged hits will certainly bust the engine. Other that the front of the truck, the protection all-round is only rated for rifle-calibre bullets and sometimes if the enemies are close enough, they can take the crew down with ease, especially MG34 on German tanks with rather high rate of fire; another problem is the rather cramped crew compartment, anything larger than 14.5 mm machine guns/autocannons will certainly gun down the crews with ease even at distance; let alone shells with explosive filler which could detonate the racks of ammo right at the centre of mass or overpressure the crew altogether. So taking cover from time to time and flank the enemies can maximize its survivability. The crew is enclosed (except the gunner), this increases the survivability to enemy air units strafing compared to previous open-topped Soviet SPAAs. The exposed gunner is very prone to get hit during enemy air attacks. The vehicle is vulnerable to close artillery strikes, which can damage or destroy the vehicle relatively easily.

=== Mobility ===
{{Specs-Tank-Mobility}}

The truck utilized the same Tatra T912-2 L6 diesel engine as the Praga V3S truck, although the revised cabin also added weight to the chassis, the truck could still travel at up to 60 km/h and reverse at a sufficient speed in case players need to make a swift escape from enemies. The speed is acceptable on roads, noticeable improvements over previous tracked Soviet SPAAs (e.g., ZiS-43, ZSU-37, etc.) but not as fast as the BTR-ZD. The M53/59 is unable to turn on the spot due to its wheeled chassis and it is hard to manoeuvre in tight and narrow streets.

{{main|ZK453 (30 mm)}}

Based on an existing WWII design and built by the Zbrojovka Vsetín and certified in 1953<ref>https://www.armedconflicts.com/CZK-vz-53-30-mm-PLDvK-t1111</ref>, the only weapon on the M53/59 is the 30 mm ZK453 autocannon with 50 shells per magazine- The rate of fire and penetration are certainly satisfying to take down aerial targets and ground targets even at distance thanks to its relative straight ballistics. But this is also not a gun for players who are trigger-happy: having only 400 rounds in total and relatively long reload time, it is best to save the shells for close targets which can utilize its HVAP shells well and fire at burst unless in emergency. The respectable turret traverse speed allows for quick response against incoming enemy air units. The M53/59 is able to fire directly forward as the crew compartment is low enough for the gun to fire horizontally towards the direction it is driving, this proves very advantageous when engaging enemy ground units as it reduces the reaction time significantly.

==== Ammunition ====

* '''Default:''' {{Annotation|HVAP-T|High-velocity armour-piercing tracer}}{{-}}{{Annotation|FI-T|Fragmentation incendiary tracer}} - This is an all-purpose ammunition belt that can be used for both anti-air and anti-ground purposes. A great belt to have during battles because it can engage all types of units without switching and reloading specific ammunition for either air or ground enemy units.
* '''30-JFSv-53:''' {{Annotation|FI-T|Fragmentation incendiary tracer}} - This is the HE belt, which should only be used against enemy air units; the ammunition is ineffective against enemy ground units, with the exception of lightly armoured tanks or other SPAA.
* '''30-JPZSv-53/59:''' {{Annotation|HVAP-T|High-velocity armour-piercing tracer}} - This is the AP belt used for anti-ground purpose. Use this belt for maximum efficiency against enemy ground units, but because it lacks HE ammunition, engaging enemy air units may be less effective.

{{:ZK453 (30 mm)/Ammunition|HVAP-T, FI-T}}

Both ammunition belts have an initial shell velocity of up to 1000 m/s, making engaging air units easily with minimal lead. The HVAP-T rounds provide high penetrating at point blank range: they can effectively damage or destroy enemy tanks in close range. Ammunition can run out really fast due to the fast firing rate with long reloads intervals, this requires extra caution when engaging multiple enemy air units.

== Usage in battles ==

The M53/59 has excellent anti-air capabilities, it also has outstanding anti-tank capabilities and a decent mobility. Despite the high-penetrating HVAP-T ammunition belt, it is critical not to stay too long in areas where the main fighting is taking place.

To use the M53/59, take note of good camping spots around each map, such as behind a house facing sideways towards a capture zone. For maximum survivability on the battlefield, it is critical to stay hidden and use cover throughout the map. For maps with little to no cover, try to stay hidden behind a hill to assess the overall situation; always look around the skies for enemy air units rather than focusing solely on the ground, as this vehicle's primary role is anti-air.

=== Playing against the enemy ===
During battle, always try to stay in cover because open areas are dangerous. Pay attention to nearby enemy tank engines and only fire if you are certain your shells will penetrate the armour (e.g., light tanks, sides of medium or heavy tanks). If the enemy spots you and tries to engage you, it's already too late. Because the M53/59 is not a dedicated anti-tank vehicle, its main disadvantage is light armour with moderate mobility when compared to dedicated light tanks. When playing in tight and narrow streets, pay close attention because the vehicle does not turn in a tight radius.

Keep an eye on the map during battle to avoid facing enemy tanks. If you receive an inbound artillery alert, always change your position because close landing artillery shells can and will severely damage or destroy your vehicle.

=== Playing against M53/59 ===
If you see an M53/59, always aim for the turret to disable the gun or at the very least knock out the gunner. Load a HE shell immediately for a follow-up shot to effectively destroy the M53/59. If you have a machine gun, use it, as there is a reasonably high chance of hitting the gunner. Never ignore an M53/59 when you see one, as an experienced enemy player can quickly tear through multiple friendly players if they are showing their flank. If you are on a light tank, avoid engaging M53/59 if possible because M53/59 has a better chance of destroying you. Immediately alert nearby friends to draw heavier armoured friendlies to deal with it.

=== Pros and cons ===


'''Pros:'''

* High penetration for an SPAA, only comes short on Bofors 40 mm L/70.
* High velocity cannon, extending its anti-aircraft/vehicle range.
* High rate of fire, will quickly shred any lightly armoured vehicle or aircraft that comes within range.
* Sufficiently fast turret traverse speed.
* 5 crew members.

'''Cons:'''

* Sluggish mobility for an SPAA.
* Overall large profile due to the huge autocannon onboard.
* Very limited protection against machine gun fire, gunner will very often be knocked out first, especially in critical moments.
* Relative slow reload to other SPAAs.
* Low ammunition count, easy to waste every magazine on aircraft without any hits within a few minutes.
* Low magazine ammunition count of on 100 (50 per gun), coupled with a high rate of fire (450 rpm), giving the user a firing time of only around 20 seconds.

== History ==

The M53/59 Praga is a Czechoslovak self-propelled anti-aircraft gun from the early Cold War era, armed with twin 30 mm AA autocannons developed in the 1950s. It was developed and introduced concurrently with the Soviet ZSU-57-2. In Czech, it was known as Praga PLDvK vz. 53/59 Ještěrka (lizard).

==== Development ====
The SPAA was built on the chassis of a heavily modified and armoured six-wheel-drive truck. The SPAA has a traditional layout, with the engine in the front, the 4-crew cabin in the centre, and the anti-aircraft gun in the back. The anti-aircraft gun is a towed ZK453 weapon system variant. The weapon system uses large vertical 50-round magazines rather than the belt feeding system found in other SPAA of the same era.

The Praga V3S is a reliable chassis, but off-road capabilities are limited due to the increased weight caused by mounting the cannon. The chassis is powered by a Tatra 110 hp diesel engine, which allows for a top speed of 60 km/h on the road. The vehicle's maximum range is approximately 500 km, and it lacks amphibious capabilities. The vehicle was manufactured from the 1950s to 1978, with a total of 1450 units produced.

The crew is only protected from small arms fire and artillery shell splinters by thin steel armour. During engagement with enemy air targets, the gunner is fully exposed on the gun mount. The M53/59 only has optical gun sights and no radar or fire control system. This severely limits its performance in poor weather, low-light conditions, or against fast-moving targets.

==== Replacement ====
While the anti-aircraft role is mostly obsolete in modern times, it can be used effectively as a support role for ground forces against enemy soft targets, particularly during the Yugoslav wars. It is still used by armies in Egypt, Libya, Serbia, and Slovakia, among others.

}}
{{Specs-Card

}}

== Description ==

The '''{{Specs|name}}''' is an infantry support vehicle designed and produced by Hägglund & Söner. The prototype of the {{PAGENAME}} was completed in 1969 and the production began in 1975, being manufactured until 1978. A estimated 212 units were manufactured and supplied to the Swedish army. During the 1980s, it was clear that the Ikv 91's firepower was insufficient to defeat later generation Soviet tanks but still powerful enough to deal with lighter armored vehicles and infantry with its 90 mm low pressure cannon, as well as laser rangefinders for a precise first shot engagement to immobilize threats from a safe distance. There were plans to improve its weaponry with a larger-calibre 105 mm Rheinmetall cannon but the turret and hull were deemed too frail and unable to support it, thus requiring an extensive modernization of the platform and would be too costly. The {{PAGENAME}} began its service in 1976 until they were slowly phased out for the new [[CV90 (Family)|CV90]] in 1993, the {{PAGENAME}}'s service didn't end until 2002.

Introduced in [[Update 1.97 "Viking Fury"]], the {{PAGENAME}} is the Swedish Army's first modern infantry support tank. Despite its low muzzle velocity, it can be equipped with a laser rangefinder to significantly improve accuracy, a feature that sets it apart from its competitors. The Ikv 91 is a real long-range predator with outstanding optics, built to engage enemies at long distances with precision. However, the vehicle is only built with relatively thin armour plates, leaving the crew vulnerable to even heavy machine guns at close range. Since engagement is usually close-up on city maps, it can be extremely challenging to play but can excel as an support tank for the heavier armoured vehicles that will take the focus away from the {{PAGENAME}}. Regardless, the Ikv 91 will undoubtedly provide unique gameplay and add to the Swedish Army's ground forces capabilities.

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

As one would expect from a light tank, the Ikv 91 is very weakly armoured. The armour, both on the front and sides, protects from small arms (like British 7.92 mms for example) and most splash damage. However, while the front hull also protects against .50 cals, the turret can be penetrated by them, which can quickly lead to death as 3 out of the 4 crew members are in the turret.

Although the commander can fire the weapon instead of a gunner, this rarely matters in any direct fight as they sit next to eachother and are both hit together. When they aren't hit, the gun is usually destroyed, often leaving the tank with only retreat as an option.

The engine and transmission are located in the rear hull, meaning that shots to the front hull are unlikely to destroy them, and shots to the rear hull are less likely to deal fatal damage as the engine and transmission will absorb most of the explosive damage, while the crew is not close enough to be hurt by the shrapnel. This does not help against pure kinetic shells whatsoever. It is ill-adviced to use engine as a shield until parts are researched, as even field repair fails to start the engine back up again and the tank literally cannot move after being disabled.

The tank rarely catches fire and usually expires before this happens. The only common source of fire is a failed airstrike that hits the engine too many times.

The tank also has 3 groups of modern aerosol smoke (usually only acquired at rank VI), these immediately explode midair and conceal the tank within 2 seconds instead of 5 or more. The implication is that they can be used to immediately separate opponents and in any position, particularly in AB, where the tank has stronger scouting (letting it to see enemy tanks through its own smoke wall). Some opponents with long reload also prefer to leave rather than fight an undamaged Ikv 91 inside its own smokes.

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=511|rbMinHp=292}}

While the Ikv 91 is slower than wheeled light tanks on road (58 km/h (36 mph) in RB/SB, 65 km/h (40 mph) in AB), it has very good mobility off-road and a good power-to-weight ratio (20.2 hp/t in RB/SB, 38.6 hp/t in AB), overall allowing it to take positions ahead of the enemy main forces and to relocate quickly.

=== Modifications and economy ===
{{Specs-Economy}}

== Armaments ==
{{Specs-Tank-Armaments}}
=== Main armament ===
{{Specs-Tank-Weapon|1}}

{{main|kan Ikv 91 (90 mm)}}

The Ikv 91 has for main armament a 90 mm gun able to use two shells: HEAT-FS and HE. All shells are unlocked from the beginning, even the excellent HEAT-FS with 400 mm of penetration and a whole 655 g TNT equivalent of explosive mass. The turret traverse speed is not the best (18.8°/s in RB/SB and 35.4°/s in AB while the American M41A1 Walker Bulldog gets 33.3°/s in RB/SB and 63.7°/s in AB), particularly when compared to future light tanks, but is above average at its BR and with upgrades is usually enough. The same goes for targeting the gun up or down.

Unfortunately, the gun also shakes a lot upon any change in movement direction, almost to an uncontrollable degree, which makes it extremely unreliable on sudden encounters, especially over uneven terrain. It is also inherently inaccurate even with all the upgrades and sometimes manages to miss the mark even with the laser rangefinder, particularly when trying to fire immediately before the gun stopped completely.

The reload speed is faster than average, but quite a few tanks reload faster at this BR, notably light tanks (the BMP-1 for example). The reload speed is also dependent on the first-stage ammo stowage, meaning that it will get slower should one run out of first-stage ammo.

The slow speed of both HEAT-FS and HE is offset by the laser rangefinder - a device on a whole level above normal rangefinders (which are also very rare at the BR), which allows the tank to automatically zero the gun scope on the target in RB, or to make shot predictions from any range in AB, making the Ikv 91 effective at long-range engagements too. It is also possible to use it from commander scope as well, which reduces the possibility of getting shot back to almost zero.

A maximum of 59 shells for the main gun can be carried, although the high-effectiveness of the HEAT shells gives the possibility for players to only carry a fraction of that and still be able to take out several targets in one run. The first-stage ammo stowage is comprised of 16 shells all located next to the loader, the next 18 shells are located in the front hull next to the driver, and the last 25 shells are located between the loader and the engine.

The Ikv 91 comes with two 8 mm machine guns: A pintle-mounted machine gun and a coaxial machine gun next to the main gun. The machine guns have a relatively slow fire-rate but are still effective at taking out exposed crew members of enemy vehicles.

|}

== Usage in battles ==


Thanks to its excellent HEAT-FS shell, the Ikv 91 can engage any target, even when up-tiered. However, a margin of caution is still needed when going against tanks that have .50 cals, as .50 cals can go through the sides and turret to then kill the gunner, loader and commander. The good mobility makes it able to go from one objective to another very quickly. The laser rangefinder also gives it the possibility to quickly make accurate long-range shots. The -10° depression also allows it to take firing positions that some other tanks cannot (particularly the Russians that usually only have -5°).

Overall, the Ikv 91 can be played at mostly any range and can outmanoeuvre most of the tanks it encounters. Although it cannot attract too much attention as its particularly weak to aircraft, but is able to use smoke shells to hide in cases like these.

=== Pros and cons ===


'''Pros:'''

* Solid mobility, especially off-road.
* Excellent HEAT-FS shell that is unlocked from the beginning.
* Laser rangefinder, a feature unheard of at its BR, allows the tank to snipe from any range.
* Aerosol smoke, another feature unheard of at its BR, allows to use smoke very aggressively.
* Reasonably good optics with a zoom level of 10x.

'''Cons:'''

* The armour does not protect against .50 cals everywhere, notably the turret.
* HEAT-FS loses velocity very quickly, making long-distance moving targets hard to hit, even when zeroed with the range finder.
* The 10x zoom, while good at longer ranges, can hinder close-quarters fights.
* Although it has a lot of strong points, almost any other light tank will destroy it rather easily if allowed to get close.
* Despite all the features designed to assist you with aiming, it will sometimes still manage to miss the target regardless, which can be fatal if the enemy is aware of your presence.

== History ==


The Infanterikanonvagn 91, or Ikv 91, was a Cold War era design made in Sweden. Although it is practically a light tank, it was designed as an infantry support vehicle, similar in role to the Russian PT-76. It was designed by Hägglunds, and ordered by the Swedish military. Hägglunds had previously designed the Pbv 302, an armoured personnel carrier. When designing the Ikv 91, Hägglunds used many parts from the Pbv 302, in order to reduce costs and increase parts commonality. The design featured a lightweight, lightly-armoured hull. The armament consisted of a 90 mm gun mounted in a turret. Secondary armament consisted of two low-calibre machine guns. The vehicle was powered by a Volvo Penta model TD 120 A diesel engine producing 330 hp. One of the requirements for the design was amphibious capability, a necessity in certain parts of Sweden. As such, it was amphibious with some preparation. The prototype was completed in 1969, but production wasn't authorized until 1975. 212 Ikv 91 were produced, and were given to infantry brigades, for use as tank destroyers. The Ikv 91 served until the early 2000s, replaced by newer designs such as the Strf 90 and Strv 121/Strv 122. In 1983, a prototype for an improved Ikv 91 model was created. This prototype mounted a 105 mm gun, instead of the 90 mm gun. It was marketed for export, but was never ordered It is often known as the Ikv 105.

''Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: <code><nowiki>{{main|Name of the weapon}}</nowiki></code>. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.''

== Usage in battles ==

''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different 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 a 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:'''

* Rockets obliterate light and heavy targets alike
* Very fast reload
* Reasonable speed

*

'''Cons:'''

* Very thin armour, will get penned by anything bigger than a machine gun
* Slow turret rotation
* Ammunition stocks go down quickly

*

== 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: <nowiki>https://wiki.warthunder.com/(Vehicle-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under <code><nowiki>=== In-game description ===</nowiki></code>, also if applicable).''

== Media ==

''Excellent additions to the article would be video guides, screenshots from the game, and photos.''
