Double Barrel Tank – Double-barreled vehicles sparked a keen interest with novices and veterans alike by offering unusual and exciting gameplay. After a series of tests and adjustments, we’re finally ready to introduce the highly anticipated branch of double-barreled heavy tanks.
But first, a brief historical overview. Starting from Tier IX, the characteristics of vehicles begin to improve noticeably. You will find that you have more armor and more firepower from both single and double shots. The IS-3-II has two 122 mm guns with 390 alpha damage each.
Double Barrel Tank

Just like most Soviet tanks, it boasts a solid, bouncy turret which absorbs a lot of damage. However, with increasing armor, the mobility of the tank is slightly reduced, although it remains fairly mobile, which is something you should take advantage of.
The Is–Ii
After a double shot, both guns are blocked for several seconds, during which they cannot fire or reload. Once the guns are available, they load in turn. After both guns are loaded, you can make a double shot again.
The number of double shots you can make has no restriction. Inclusive Energy’s 200-100 BBL tanks are manufactured to exceed industry standards. They are designed in accordance with API12F, 620 and 650 design specifications, including dimensions and internal and external pressures.
Our tanks are externally insulated and we offer 100% internally coated models that are available for sweet or sour projects. When you want to shoot at an enemy vehicle, just aim and fire, as with any regular tank.
After shooting the active, let’s say, left gun, it starts reloading. The second one (the right gun) now becomes active. When the left gun is loaded, take a shot with the right gun. Then the right gun starts reloading, the left one becomes active again, and the cycle repeats.
Cyclic Regular Firing One Gun That Reloads After Each Shot
The principle of shooting is like any other tank, only with the additional movement of the aiming camera. Researching the new sub-branch of double-barreled Soviet heavy tanks starts with the KV-3 at Tier VII. You’ll be able to move along the heavy branch or research these new double-barreled predators.

In Update 1.7.1, the following three new vehicles will storm the battlefield: You must hold the left mouse button to prepare the shot (this takes a few seconds). The reloading progress timer is displayed inside the scope area.
When the preparation is complete, a double shot automatically occurs. If you release the left mouse button before the preparation ends, the process will reset. The development of armored vehicles with twin guns began between the First and Second World Wars.
The greatest progress in this field was achieved by Soviet engineers who developed several projects of double-barreled tanks during World War II. In 1939, testing of the first Soviet double-barreled tank, which received the KV-U-0 index, was successful, and by 1941, there were two projects: the T-34-3 and the KV-7.
Meet The Double-Barreled Heavies
Penetration and alpha damage for each of the two shells are calculated separately. Accordingly, one shell may penetrate armor and cause damage, while the other may fail to penetrate or ricochet. It’s also possible for both shells to penetrate the armor but deal different amounts of damage.
The fabulous ST-II crowns the branch — the most famous tank of the entire trinity, and the only one that exists in reality. Also, it was the ST-II that our players have long been asking to be added to the game.
After shooting the active left gun, the camera shifts, but you can’t fire the second gun right away. The timer on the left shows when you can shoot. When it finishes, you can fire from the second gun.
Remember though that the loading of the first gun will be interrupted, and the sequential loading of both shells will start over. Several factors kept us from implementing this mechanic in World of Tanks. First, its historical background: In real life double-barreled tanks rarely even reached the prototype stage.

Double Shot Simultaneous Shots From Two Guns
It was difficult to assemble a whole branch from existing historical vehicles. The most entertaining way. To shoot two guns at the same time, you need to hold the left mouse button to prepare the shot (this takes a few seconds).
Reloading progress is displayed inside the scope area. When the preparation is complete, a double shot automatically occurs. If you release the left mouse button before the end of preparation, the shot preparation resets. No shots — single or double — will happen.
Double-barreled tanks were considered an innovative and breakthrough technical solution for their time, however. They would have had a higher chance of successfully defeating a target and were designed to play an important role on the battlefield — namely, to break through the enemy’s defenses or to hold back their advance.
If you are requiring some extra customization Inclusive Energy also keeps a stock of bare steel cans that are ready for quick modification and fast turnarounds. We can also produce equipment that is customized and specialized for your needs.
Looking Back In Time
Shop fabricated tanks ranging from 50bbl to 3000bbl capacity and up to 23’6″ in diameter and up to 48′ in height. World of Tanks veterans may remember the fabulous American MTLS-1G14 Premium Tier III light tank introduced in 2011. It was the first vehicle with a twin gun in the game and sparked interest among players, as it offered unusual and exciting gameplay.
All characteristics of this Tier X tank — alpha damage, penetration, armor — are at their maximum values among all vehicles in the entire branch, which makes the ST-II the ultimate brawler. This is a full-fledged heavy tank, which will be a huge problem for the enemy, even with little support.
With this tank you have access to all three shooting modes—cyclic, sequential, and double-shots. Given this is a transitional stage to a new branch, it is a good opportunity to practice using the cyclic (regular) mode to get used to some of the nuances of having two guns on your vehicle.

Let’s review its mechanics. You shoot the first (active) gun. Immediately after this, the gun begins to reload, and the second one is active. You can shoot the second gun after a short delay — a pause that is better known to players as reloading shells inside the autoloader.
Penetration Damage And Change Of Shells
If you’ve played Italian tanks with an autoreloader, you should be familiar with this mechanic. The concept of a double-barreled vehicle is not final. It’s very likely these machines will have mediocre mobility, a high turning speed, and more.
We need to test the viability of our concept and refine their mechanics to make sure this type of tank is well placed to fit the World of Tanks ecosystem. The decision to introduce them into the game is not final, and depends on the test results.
The first designs of tanks with multi-barreled guns appeared back in 1941. Soviet engineers worked on a three-barreled version of the T-34, called the T-34-3, and two- and three-gun versions of the KV- 7, but none of these prototypes ever left the drawing board.
One of the most famous projects of this type is the two-gun version of the ST-1, named the ST-2. This modification is the most well-known to players, although it was never brought to life in metal.
The St-Ii
Both of the above constraints were not in-game obstacles for creating a new branch, so we’ve reinforced and developed the ideas of the Soviet engineers. In creating these vehicles, we’ve taken into account many nuances and tried to comply with all principles of the construction of such tanks.
For example, all double-barreled tanks have an extended track platform, improved chassis, enlarged turrets, and other features. All vehicles are not only correct from an engineering point of view, but they also retain the visual features of the Soviet tank-building school.

Although its name has the abbreviation of the legendary IS, the tank in its components is more similar to the KV-3, which, like the IS-2-II, was equipped with a 100 mm gun. Although it doesn’t pack much damage, the IS-2-II is a versatile vehicle and a good training platform.
In addition, the 100 mm guns are comfortable to shoot, which helps you to better master their mechanics. It takes a shorter time to prepare for the shot, and the penalty after a double shot is also reduced.
Sequential Shooting Both Guns Alternately
You need to take into account the specifics of a particular game situation and make one shot somewhere and a double shot somewhere else. For example: If you need to finish off an opponent with a small amount of HP, it’s logical to make one shot.
But if you’re faced with an enemy driving sideways, it makes sense to take a double shot and then roll back to cover to reload. Try to think in advance which is the most effective in a given situation.
If properly used, its tough hull with well-sloped armor will easily deflect enemy rounds. The ST-II is equipped with two 122 mm guns with 440 points of alpha damage. Keep in mind the top speed of this goliath is rather low, so decide in advance on which section of the map you will battle — you won’t be able to quickly change the flank.
