== History ==
On May 14th 1953, right after Stalin's death and the reopening of the Sukhoi OKB, they began work on a swept-wing front-line fighter. their first prototype was named '''S-1''' and was fitted with the all-new Lyulka AL-7 turbojet, and it was the first Soviet aircraft to utilize the all-moving tailplane and a translating centerbody, plus a a dramatic wing sweep of 60°, irreversible hydraulically boosted controls, and an ejection seat of Sukhoi's own design. After the success of he S-1, production began with the S-2. later renamed the '''Su-7'''.

Later, on 31 July 1958, the Soviet tactical aviation tasked Sukhoi with developing a ground-attack variant of the Su-7, which could replace the scrapped Ilyushin [https://wiki.warthunder.com/IL-10 Il-10]. The resulting prototype, '''S-22''', incorporated structural refinements for high-speed, low-altitude operations. It first flew in March 1959, and entered service in 1961 as the '''Su-7B'''.

=== 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:'''

* Has the best ATGM ingame, with an astounding 1200 mm of penetration
* Great mobility and acceleration
* Frontal armor, despite lightly armored, is heavily sloped, meaning its immune to almost all SPAA autocannons, it can even rarely bounce some tank shells

'''Cons'''

* The armor can be easily penetrated on all sides by any gun it meet (short of some SPAA autocannons), even heavy machine guns can penetrate some areas of the side.
* Main gun is hard to aim

== History ==

=== '''Development''' ===
The Khrizantema anti-tank missile was unveiled in July 1996 by the Konstruktorskoye Byuro Mashynostroyenia Engineering Design Bureau, or simply KBM. It started development in the 1980s and was designed as an all weather, multi-purpose missile system that could defeat current and future armoured units equipped with advanced armour protection, such as Explosive Reactive Armour. It was intended to replace old soviet ATGMs such as the [https://wiki.warthunder.com/Shturm-S 9K114 Shturm] and the 9M120 Ataka-V. The system entered service with the Russian armed forces in 2005.

=== Description ===
The 9M123 missile is supersonic, flying at an average speed of 400 m/s or Mach 1.2 and has a range of between 400 and 6,000 meters. Guidance control is provided by two pop-out control surfaces at the rear of the missile (four additional surfaces help stabilize the missile during flight). The Khrizantema is unique among Russian anti-tank guided missiles as, depending on the variant of the missile, it can either be guided by laser or radar. Each missile carries a tandem HEAT warhead that can penetrate up to a recorded 1100–1250 mm RHA (Rolled Homogeneous Armour) behind ERA. Alternatively, a thermobaric warhead can be carried to engage soft-skinned targets, fortifications and manpower. It is currently launched from the 9P157-2 Khrizantema-S tank destroyer, Mi-28 Havoc attack helicopter and most likely in the near future from the Ka-52 Alligator attack helicopter as well.

== Description ==

[[File:GarageImage_SU-122.jpg|420px|thumb|left]]
{{break}}
The '''{{specs|name}}''' is a rank {{specs|rank}} Soviet tank destroyer {{Battle-rating}}. It was introduced during the Closed Beta Test for Ground Forces before Update 1.41. This vehicle was created on T-34 chassis. It carries a fearsome 122 mm M-30 howitzer.

The main feature of this SPG is a powerful gun, but make good use of the first shot. It is very hard to hit targets from over 500 m in realistic and simulator battles. One good tactic would be to rush an enemy tank and shoot him at point-blank range but this only works if there is no other enemy tank because with an untrained crew it can take up to 33 seconds before the {{PAGENAME}} has reloaded.

== History ==

===Development===
The success of the Germans [[StuG III F|StuG III]] and other self-propelled assault gun took the Soviet High Command's interest on the concept. Self-propelled guns were generally considered cheaper and more easily produced compared to regular tanks due to the lack of turret, plus it could be made with a large fighting compartment and bigger guns than those that could be mounted on turrets, the only drawbacks to the designs were limited traverse of the gun so it would do poorly in close-quarters situations.

On the 15th April, 1942, the Soviets asked design bureaus to begin development of assault guns using a wide selection of armament ranging from their 76.2 mm ZiS-3 field guns, 122 mm M-30, and 152 mm ML-20 howitzers. The prototype assault gun was armed with the 122 mm and was quite similar to the StuG III's design, designated the SG-122, of which only 10 were made due to reliability issues. The next step was to take the standard issued Soviet tank, the [[T-34 (1941)|T-34]], and convert that into the assault gun. The prototype, U-34, was created in summer of 1942 in the Uralsky Machine Building factory by N. W. Kurin and G. F. Ksjunin. It initially had the same armament of 76.2 mm, but it was 70 cm lower than the regular T-34 and had more armour at a lighter weight, this did not enter production. Another work was done to combine the U-34 features with the SG-122, this was completed in around late summer of 1942 and featured the U-34 chassis with the 122 mm armament placed on with the least modifications possible to keep the design affordable and easy to produce. This new design, now the U-35, was created on November 25, 1942, and was sent for evaluations. There were faults discovered in the elevation mechanism, loading system, and ventilation for the crew. Despite these flaws, the vehicle was accepted into service first as the SU-35 but then renamed the '''SU-122'''. Several modifications were made to the vehicle during production, such as simplifications to the design, modified interior layout, removed vision slots, and added a commander's periscope. The production began in December 1942 and continue on until summer of 1944 with 1,150 total unit produced.

===Design===
The vehicle was based off the T-34 chassis, so it uses the same running gear, engine, suspension, and tracks as the T-34. This is consistent with the concept of utilizing the chassis of proven vehicles and converting them into other uses. The design mounted the 122 mm M-30 howitzer, which was made for infantry support in a role similar to the StuG III in German usage. The M-30S howitzer could be elevated or depressed between −3° and +26° and had 10° of the traverse. The design had no armour advantage over the standard T-34 with 45 mm thick frontal armour to keep production simple. The design had a crew of five, the driver, gunner, commander, and two loaders to load the 122 mm shells.

===Combat usage===
The first few SU-122s created were sent to training centres and to two combat units, the 1433rd and 1434th self-propelled artillery regiments. Each regiment was intended to have two batteries of four SU-122s and four batteries of four [[SU-76M|SU-76s]]. Thirty of such self-propelled artillery regiments were planned to be raised in the armour and mechanized corps. In January 1943, the 1433 and 1434 regiments were sent to Leningrad near the Volkhov Front to support the 54th Army. These regiments and their self-propelled guns first saw action on January 14 in the Smierdny region. Combat experience showed that the best deployment of the SU-122s was about 400 to 600 meters behind advancing tank units, to which it was sometimes reduced to just 200 meters minimum distance. The mixed deployment of the SU-76 and the SU-122 was a failure and the organization was changed. The new system had two batteries of SU-76 and three batteries of SU-122s for 20 vehicles, this was changed again in April for separate regiments for SU-76s and SU-122s (called "light" and "medium" respectively). The medium self-propelled artillery regiments had four batteries of four SU-122s each for 16 vehicles. An additional SU-122 or T-34 was added as a commander for the regiment, along with a BA-64 armoured car for reconnaissance duties. This organization of the self-propelled artillery regiments stayed until the beginning of 1944 as newer and better self-propelled guns such as the [[SU-85]], [[ISU-122]], and [[ISU-152]] were being produced, when the SU-122 was beginning to be phased out as well.

The SU-122 in combat proved very effective in its role as direct fire support on strongholds. The high-power high-explosive rounds create a massive concussion blast on impact and may be powerful enough to even knock the turret off a [[Tiger H1|Tiger I]] tank. Until May 1943, only the HE rounds were available for the 122 mm gun, but the BP-460A HEAT rounds were introduced on that month that could theoretically penetrate any armour the German have on their tanks, but the HEAT round's primitive design and fuse, adding the gun's inaccuracy, caused the SU-122 to not be an effective tank destroyer.

The SU-122 was never mass-produced in multiple variants, however, some were converted into prototypes. The ''SU-122M'' had a larger compartment and newer D-11 gun, and the ''SU-122-III'' had an even lighter gun than the D-11, but was unsuccessful due to unreliability. Both of these were cancelled when production priorities went to the [[SU-85]] design.

===Survivors===
Only a small number of SU-122s survive the war, with only one known example on display at the Kubinka Tank Museum.

=== In-game description ===
"This SPG armed with a 122 mm М-30 Mod. 1938 howitzer was developed in October-November 1942 to support and escort tanks. In December of the same year, it entered production and was put into service.

The SPG was built on a T-34 chassis with an armoured cabin containing the driving compartment and the fighting compartment. To protect the howitzer's recoil mechanism, a large forward-extending armoured mantlet was used which swung with the weapon. The gunnery equipment could be used to fire both directly and from cover. The howitzer's ammunition load of 40 shots included high-explosive fragmentation shells and hollow-charge projectiles. The vehicle's undercarriage differed from the T-34 in the strengthened head assembly of its suspension. A 9R radio set was mounted on the SPG, along with the TPU-3-BisF intercom.

The vehicle was produced throughout 1942-1943, with 638 manufactured in total. Throughout its production, a large number of modifications were implemented with the aim of improving the vehicle's quality and simplifying its manufacturing. Work performed on perfecting the manufacturing and assembly technologies involved reduced the labour costs of its production by 15%.

The SU-122 was put into service in SPG regiments in quantities of up to 16 vehicles per regiment.

The SPG's flaws were: its small horizontal firing angle and complex aiming; long barrel length complicating manoeuvring on rough terrain and in urban areas; low rate of fire in combat; relatively small on-board ammunition capacity; and lack of a machine gun for self-defence. In spite of these flaws, the SU-122's high firepower, manoeuvrability and defensive capabilities made it a dangerous opponent in battle."

{{Specs-Card|code=ussr_su_122}}

== Description ==

[[File:GarageImage_SU-122.jpg|420px|thumb|left]]
{{break}}
The '''{{specs|name}}''' is a rank {{specs|rank}} Soviet tank destroyer {{Battle-rating}}. It was introduced during the Closed Beta Test for Ground Forces before Update 1.41. This vehicle was created on T-34 chassis. It carries a fearsome 122 mm M-30 howitzer.

The main feature of this SPG is a powerful gun, but make good use of the first shot. It is very hard to hit targets from over 500 m in realistic and simulator battles. One good tactic would be to rush an enemy tank and shoot him at point-blank range but this only works if there is no other enemy tank because with an untrained crew it can take up to 33 seconds before the {{PAGENAME}} has reloaded.

== History ==

===Development===
The success of the Germans [[StuG III F|StuG III]] and other self-propelled assault gun took the Soviet High Command's interest on the concept. Self-propelled guns were generally considered cheaper and more easily produced compared to regular tanks due to the lack of turret, plus it could be made with a large fighting compartment and bigger guns than those that could be mounted on turrets, the only drawbacks to the designs were limited traverse of the gun so it would do poorly in close-quarters situations.

In April 1942, the Soviets asked design bureaus to begin development of assault guns using a wide selection of armament ranging from their 76.2 mm ZiS-3 field guns, 122 mm M-30, and 152 mm ML-20 howitzers. The prototype assault gun was armed with the 122 mm and was quite similar to the StuG III's design, designated the SG-122, of which only 10 were made due to reliability issues. The next step was to take the standard issued Soviet tank, the [[T-34 (1941)|T-34]], and convert that into the assault gun. The prototype, U-34, was created in summer of 1942 in the Uralsky Machine Building factory by N. W. Kurin and G. F. Ksjunin. It initially had the same armament of 76.2 mm, but it was 70 cm lower than the regular T-34 and had more armour at a lighter weight, this did not enter production. Another work was done to combine the U-34 features with the SG-122, this was completed in around late summer of 1942 and featured the U-34 chassis with the 122 mm armament placed on with the least modifications possible to keep the design affordable and easy to produce. This new design, now the U-35, was created on November 25, 1942, and was sent for evaluations. There were faults discovered in the elevation mechanism, loading system, and ventilation for the crew. Despite these flaws, the vehicle was accepted into service first as the SU-35 but then renamed the '''SU-122'''. Several modifications were made to the vehicle during production, such as simplifications to the design, modified interior layout, removed vision slots, and added a commander's periscope. The production began in December 1942 and continue on until summer of 1944 with 1,150 total unit produced.

===Design===
The vehicle was based off the T-34 chassis, so it uses the same running gear, engine, suspension, and tracks as the T-34. This is consistent with the concept of utilizing the chassis of proven vehicles and converting them into other uses. The design mounted the 122 mm M-30 howitzer, which was made for infantry support in a role similar to the StuG III in German usage. The M-30S howitzer could be elevated or depressed between −3° and +26° and had 10° of the traverse. The design had no armour advantage over the standard T-34 with 45 mm thick frontal armour to keep production simple. The design had a crew of five, the driver, gunner, commander, and two loaders to load the 122 mm shells.

===Combat usage===
The first few SU-122s created were sent to training centres and to two combat units, the 1433rd and 1434th self-propelled artillery regiments. Each regiment was intended to have two batteries of four SU-122s and four batteries of four [[SU-76M|SU-76s]]. Thirty of such self-propelled artillery regiments were planned to be raised in the armour and mechanized corps. In January 1943, the 1433 and 1434 regiments were sent to Leningrad near the Volkhov Front to support the 54th Army. These regiments and their self-propelled guns first saw action on January 14 in the Smierdny region. Combat experience showed that the best deployment of the SU-122s was about 400 to 600 meters behind advancing tank units, to which it was sometimes reduced to just 200 meters minimum distance. The mixed deployment of the SU-76 and the SU-122 was a failure and the organization was changed. The new system had two batteries of SU-76 and three batteries of SU-122s for 20 vehicles, this was changed again in April for separate regiments for SU-76s and SU-122s (called "light" and "medium" respectively). The medium self-propelled artillery regiments had four batteries of four SU-122s each for 16 vehicles. An additional SU-122 or T-34 was added as a commander for the regiment, along with a BA-64 armoured car for reconnaissance duties. This organization of the self-propelled artillery regiments stayed until the beginning of 1944 as newer and better self-propelled guns such as the [[SU-85]], [[ISU-122]], and [[ISU-152]] were being produced, when the SU-122 was beginning to be phased out as well.

The SU-122 in combat proved very effective in its role as direct fire support on strongholds. The high-power high-explosive rounds create a massive concussion blast on impact and may be powerful enough to even knock the turret off a [[Tiger H1|Tiger I]] tank. Until May 1943, only the HE rounds were available for the 122 mm gun, but the BP-460A HEAT rounds were introduced on that month that could theoretically penetrate any armour the German have on their tanks, but the HEAT round's primitive design and fuse, adding the gun's inaccuracy, caused the SU-122 to not be an effective tank destroyer.

The SU-122 was never mass-produced in multiple variants, however, some were converted into prototypes. The ''SU-122M'' had a larger compartment and newer D-11 gun, and the ''SU-122-III'' had an even lighter gun than the D-11, but was unsuccessful due to unreliability. Both of these were cancelled when production priorities went to the [[SU-85]] design.

Only a small number of SU-122s survive the war, with only one known example on display at the Kubinka Tank Museum.
