== Description ==


Arguably the single most iconic self-propelled anti-aircraft gun of the Soviet Union during the Cold War, the '''ZSU-23-4 ''Shilka''''' is a force to be reckoned with. First fielded in 1965, the Shilka completely superseded its predecessor, the antiquated [[ZSU-57-2]] by the 1970s. Notable upgrades were a radar fire control system to assist gunners in aiming the gun, a gun stabilizer to enable firing on the move, as well as the search radar itself which greatly assisted in awareness. Designed on the [[ASU-85]] hull, the Shilka was almost fielded alongside its competitor, the [[ZSU-37-2]] Yenisei, but the Yenisei was cancelled during a hearing and the Shilka became the backbone of the Soviet air defense suite. The Shilka served a long and illustrious career with the Soviet Armed Forces and many other militaries around the world, seeing combat across the globe. One notable use was in the Soviet-Afghan War, where Shilkas had their radars removed and additional ammunition was added and were used against enemy guerilla fighters to devastating effect.

Introduced in [[Update 1.63 "Desert Hunters"]], the "Shilka" presents a much higher rate of fire than its predecessor [[ZSU-57-2]], and allows the user to oversaturate a given area of the sky to increase the odds of hitting an enemy aircraft. The Shilka is unlocked after the [[ZSU-37-2]] Yenisei, its unproduced rival, and usage cases between the two differ. The Yenisei deals a heavier, crippling blow with its 37 mm cannon, but lacks the volume of fire of the Shilka to saturate an area, while the Shilka lacks comparative engagement range as well as the penetration to go through enemy armour from the side consistently. The Shilka is best used at sub-2 km ranges, when enemies have little room to manoeuvre from the sheer amount of shells being thrown in the air, and is second to none in this role.

{{main|AZP-23 (23 mm)}}The ZSU-23-4 is armed with the AZP-23 quad-mount autocannons onboard; known as the ''sewing machine'' due to its iconic firing sound. There were field modifications which even has its radar systems removed to store extra ammunition against insurgents; this also somewhat showed a major downside of the system - inferior, or perhaps old-school radar system. Although the sound from the firing can sometimes deter enemy aircrafts, for players who understand the rather curved trajectory of the 23 mm autocannon, they will have easy time taking down the Shilka; sudden attack with the autocannons is always the best idea to utilize the vehicle. Leave the shells for aircrafts instead as the penetration of 23 mm shells are rather disappointing, sometimes barely able to penetrate NATO tanks from their sides.

{{main|1RL33}}
The ZSU-23-4 is equipped with a [[1RL33]] search and tracking radar, mounted on top of the turret, at the rear. The radar system lacks track while scan, but can track targets in a full 360° area around the turret (instead of just to the front of the turret). The radar has very slow scan speed.
{{Notice|By default the radar will scan a 90° arc, this can be changed to a 60°, 30°, or 360° scan if desired, using the "change radar search mode" key.}}

== Usage in battles ==


The ZSU-23-4 should be played entirely as an AA vehicle. Do not go tank hunting in this vehicle, as you do not have the armour or the penetration. Focus on keeping the skies clear, something that this vehicle does very well. A high rate of fire and very fast turret traverse means that you should be able to target and destroy even the fastest jets.

You have a high ammo count with this vehicle, meaning that you can afford to find a good spot away from the main fight in order to pick off enemy planes. Unless you need to reload your ammo, avoid spawn points. They are usually the hub of most of the fighting and going to them will put you in the firing line.

While it is fully enclosed, the ZSU-23-4 has armour which makes the M18 Hellcat look like a heavy tank. Even 7.62mm machine guns stand a fair chance of penetrating this vehicle, although the slightly increased angle provides marginally better protection over the Yenisei. This makes you a primary target for aircraft, which at this vehicles BR are usually armed with cannons or high penetration machine guns, which will easily take you out.

Top rank helicopters and the FJ-4B VMF 232 are the greatest threat to your existence. They are both capable of sitting comfortably outside your firing range while firing lethal ATGMs at you. Hide from them until they are either dealt with by an allied plane or they come close enough to be dealt with by your 23 mm cannons.

=== Pros and cons ===


'''Pros:'''

* High rate of fire with quad-mount 23 mm autocannons which can be devastating
* Generous ammunition pool for prolonged firing
* Chassis is mobile enough to navigate in the battlefield with relatively high top speed
* Sufficient turret traverse speed for quick targeting
* Can penetrate lightly armoured vehicles (other SPAAs)
* Radar-assisted fire control, even with weak radar it still makes taking down aircraft much easier

'''Cons:'''

* Large vehicle profile makes for a easy target when spotted
* Little armor protection: heavy machine guns can penetrate the turret and hull
* Low power to weight ratio; struggles with slopes and off-road
* Huge ammo rack by the front of the turret with a high risk of detonation
* Obsolete radar systems that hinders overall search capabilities: visual and aural searches may be more reliable

== History ==


===Development===
The main Soviet self-propelled anti-aircraft vehicle [[ZSU-57-2]], in service since 1955, did not perform satisfactory due to the lack of radar tracking, low rate of fire, and small ammo count for its high-power autocannons. Its firepower was supplemented by the ZPU and ZU series of anti-aircraft mounts using the 14.5 mm and 23 mm armaments respectively. The ZPU and ZU were towed or truck-mounted and had a high rate of fire, but suffered from low mobility when not on a truck and lack of protection if mounted on a truck for a mobile role. It became desirable to combine the traits of these two type of anti-aircraft weaponry together for a tracked anti-aircraft vehicle to be protected, have good mobility, contain a good amount of ammo, and deliver a high rate of fire with heavy-hitting calibre.

Development started in 1957 for this vehicle, ready to be evaluated in 1962. The vehicle went under the name '''ZSU-23-4 "Shilka"''', named after the Shilka River in South-Eastern Russia. The first set of digits signifies the calibre, 23 mm, and the second signifies the number of cannons, 4. Equipped with four water-cooled 23 mm autocannons, the ZSU-23-4 is aimed via manual optics or with a radar that can track aircraft up to 6 km away and guide the armaments to a estimated coordinate. The vehicle can carry up to 2,000 rounds of 23 mm ammunition and each cannon has a fire rate of between 850-1,000 rpm. The ZSU-23-4 was built on a GM-575 chassis, which itself is based off the [[PT-76B|PT-76]]. It was accepted for service by the Soviet Army in 1965 and proceeded to replace all the ZSU-57-2 still in stock by the 1970s. From the time period 1964 to 1982, up to 6,500 ZSU-23-4 were produced at the Mytishchi Engineering Works.

===Combat usage===
The Soviet Army used the ZSU-23-4 as their main anti-aircraft defense weapon. It was intended that the ZSU-23-4 only guard military bases and mechanized formations while the ZSU-37-2, a side development during the Shilka's development period, guard the low-altitude area unable to be hit by surface-to-air missiles. However, the ZSU-23-4 Shilka eventually replaced it to keep a logistics simple. From Soviet doctrine, the Shilkas were organized in anti-aircraft artillery batteries with two platoons of four vehicles each. Initially, one platoon was filled with ZSU-57-2's and the other with Shilkas, but the ZSU-57's were replaced in service by the Shilkas in the 1970s. In the 1970s, the batteries were also reorganized to one platoon of Shilkas and one platoon of anti-air missile systems, both meant to supplement the dead zone from the divisional surface-to-air missile systems. The Shilkas, being very lightly armoured, mainly stay behind the main forces and the front line, ranging between 400 to 1,000 m away from the fighting. Though each Shilka unit fought with their own radar system initially, the implementation of the PPRU-1 allowed for coordinated targeting between the Shilka and missile units against enemy aircraft. Despite their intended role as an anti-aircraft, the high rate of fire, heavy calibre, and ability to elevate the guns at a high angle made it a very popular ground support weapon. This utility made it a very useful weapon in the Soviet occupation of Afghanistan, being able to fight the Mujaheddin ambushing from mountainous terrain. The Soviets also used it during the War against Chechnya, fighting the Chechens in the mountains. The ZSU-23-4 still sees use in the Russian Naval Infantry.

The ZSU-23-4 saw more usage in the hands of the Soviet Union's allies. 2,500 of the Shilkas produced were given out to up to 23 nations. It's most infamous records would come from the hands of the Arabs in the Yom Kippur War in 1973. Using the SA-6 surface-to-air missiles, they forced the Israeli planes to fly low to avoid missile detection and then blasted them away with the Shilkas. The Shilkas also saw use in the later part of the Vietnam War, where they are used nearly the same way by attacking aircraft forced low by missiles. Past that, the ZSU-23-4 saw usage in multiple conflicts in the Third World countries and are still in use today in the Syrian Civil War.

==Description==

[[File:Radar_1RL33.jpg|thumb|300px|right|The 1RL33 / RPK-2 atop the turret of a [[ZSU-23-4]]]]

The '''1RL33''' or '''RPK-2 "Tobol"''' is a Soviet [[SPAA radars|ground-based target detection and tracking radar]].

===Vehicles equipped with this radar===


* [[ZSU-23-4]]
* [[ZSU-23-4 (Israel)]] - Israeli-captured version
* ◔[[ZSU-23-4 (Italy)]] - Hungarian version
* [[ZSU-23-4M4]]

==General info / usage==


The 1RL33 is capable of both scanning for targets and locking onto targets, however it does not offer "Track While Scan" (TWS) capability, this means that the radar must cease scanning in order to lock onto a target. As a result of this if a target is locked onto then all other radar blips will stop updating and be removed from the display within a few seconds. Upon a target lock being lost the radar will revert to scanning. When the radar is locked onto a target it will stop sweeping and instead point directly towards the target, following it as the target moves.

The radar has a "Line of Sight (LoS) scan" mod. In this mode the radar dish is locked in place facing the front of the turret, as such it will only detect targets within a very narrow azimuth range, relative to the front of the turret, however elevation scanning angles remain unchanged. In LoS mode the radar (and thus the turret) need to be directly facing a target in order to detect it, once a target has been detected it can be locked onto in the normal manner and the radar will automatically follow it; once a lock is lost the radar will revert to LoS mode and face the front of the turret. The benefits of operating the radar in LoS mode are that as the radar is not emitting in all directions you will not alert enemy aircraft equipped with radar detectors to your presence unless you aim directly at them.

The default scanning mode of the 1RL33 is to scan a 90 degree arc. It is possible to switch the radar into scanning a full 360 degree, although due to the incredibly slow scanning speed this option is rarely desirable.

===Comparison with analogues===


Compared to other search and tracking radars the 1RL33 has a decent range of 20 km for detection and 16 km for tracking. It is the only search radar primarily designed for scanning a small sector, instead of 360 degrees; as such it has an incredibly slow scanning speed. Being a combined search and tracking radar like the [[Marconi S 400]] the 1RL33 lacks track while scan capability, however like the Marconi it can also track targets through a full 360 degrees.

===Pros and cons===


'''Pros:'''

* Decent Range
* Can track targets through a full 360 degrees
* Good minimum range
* Radar shuts down immediately when turned off and stows away only marginally taller than the turret

'''Cons:'''

* Slow scanning speed
* Slow scan speed makes 360° Scan mode of limited use.
* Lacks "Track While Scan" capability

== History ==


The 1RL33, also known as the RPK-2 "Tobol" was a soviet radar developed in the 1950s for use on the [[ZSU-23-4]] SPAA vehicle. The radar reportedly suffered from high levels of ground clutter (false returns on the radar display) under certain operating conditions, but offered good resilience against radar countermeasures.

The NATO reporting name for the radar system was "Gun Dish".
