Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available ammunition

BR-471 - Casual, and stock APHE shell with decent penetration of 205 mm on distance of 10 meters. Fairly slow muzzle velocity that's just shy of 800 m/s. Contains plenty of explosives ( TnT equivalent of almost 250g!)

BR-471B - APHEBC shell. Is identical in terms of explosives, muzzle velocity. Balistic cap lowers the decrease of penetration over distance, and slightly changes penetration chance on different angles.

OF-471 - HE shell. Contains 3.6kg of TNT inside, which translates to 37mm of penetration that is not dependant on angle or distance. Barely faster than APHE shells.

BR-471D* - APCBC shell. Contains just over 190g of TNT inside. It's muzzle velocity is 800m/s, and has penetration value of 230mm on distance of 10 meters.

*Avalible only on IS-3 and IS-4

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

IS-2 & KV-122

The 122 mm cannon can penetrate almost every enemy tank frontally (exceptions exist: Tiger I vision port, Tiger II hull, as well as american heavy tanks turrets frontally), and reliably knock outs the tank in a single shot because of the high amount of explosive filler. The downside of such firepower is the long reload which forces you to engage from a distance.

IS-3, IS4-M & T-10A

Tank's armour gets tougher to pierce at higher ranks and their guns are also improved. Chemical energy shells are more common, which means that getting rid of enemies in a single blow is really important. Well armoured enemies are going to withstand your shells easily, so heavy tanks will be difficult to deal with. MBTs on the other hand will most likely penetrate you easily, but that's a double edged sword for them: they can penetrate you but you can also penetrate them. They may have a mobility advantage, but in terms of post-penetration damage you definitely are ahead of them.

Pros and cons


  • Amazing penetration (at IS-2's BR) and post-penetration damage effects often leads to taking out enemy vehicles with a single shot
  • The later APHE shell (BR-471D) has slightly better penetration, while still retaining its wonderful post-penetration damage
  • Stock shell (BR-471) has similar performance to the later BR-471B on the IS-2


  • Slow reload of around 20 seconds, mid-range sniping or providing heavy fire for your team is advised
  • Has poor elevation angles on all models equipped with it.
  • When attacking different targets, switching ammo types will take time
  • At IS-3 or IS-4M's BR, it can't reliably penetrate tanks frontally


Examine the history of the creation and combat usage of the weapon 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 weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.


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