Gun Mount "Object 261"

Many fans of the online game World of Tanks familiar with the self-propelled artillery increased power under the name of "Object 261".Gamers cleverly destroy enemies, driving this Arta, but few of them know that the ACS has never participated in any battle.Consider the story of the creation of the artillery unit.

ACS "Object 261": how it all began

Despite a number of setbacks that have befallen previous ACS, the Soviet leadership even after the war did not leave the idea to put on a self-propelled chassis heavy duty gun.This self-propelled gun was developed design bureau of the Leningrad Kirov Plant and Chelyabinsk.A base for the development of a new ACS has become a favorite with players tank IS-7.The project began this gun mount developed immediately after the end of World War II and was finished in 1947.The motor engineers used the ship's diesel power unit M-50 increased power, of course, at first adapting it to the tank."Object 261" outfitted lightly armored open deckhouse, which placed a very powerful gun M-31 (152mm).

feat CB plant №172

Its specially created for this project in the design office Perm factory №172.A base served as a ballistics artillery gun BR-2.M-31 in order to save has been unified with the tank gun M-51 a number of parts and mechanisms.The first tests of the M-31 took place in October 1948.Designers of so much modernized BR-2, which was quite difficult to find the common elements in these two instruments.CB plant №172 hosted a truly grandiose work, new gun from her predecessor characterized by the presence of semi-automatic horizontal wedge gate, unlike the piston in the BR-2.In addition, she had a slit rather powerful muzzle brake that can absorb energy up to 70% retracement.Gun barrel was equipped with a very massive breech that will ensure the desired mass sliding mechanisms, and contributed to a better balancing of the swinging.

The principle of guns

Loading the gun was a new separate-case.The projectile shall be sent through the spring loading rod, automatically cocking during pullback.In addition, the mechanism responsible for purging the barrel, also worked in the automatic mode.It uses compressed air, which is in a special tank.The brake hydraulic recoil from the gun and pneumatic recuperator, the cylinders of these devices are rigidly connected with the barrel.As a result, due to the breech of the gun recoil system and significantly increased the weight of a sliding part.This, together with a muzzle brake, gave a very small pullback gun.Turning and lifting mechanisms with self-locking worm link were sector type.

M-31 - a gun that has no analogues in the world

have turned this gun truly unique characteristics.Thus, the firing range was 27,800 meters (nearly 28 km), and that the initial flight velocity projectile 880 m / s.Gun M-31 gun was equipped with direct fire TP-47A, and for firing from covered positions - ZIS-3.

did not expect

As already mentioned, as a way for the ACS database with increased capacity was elected tank IS-7 ("Object 715").However, the draft has not been approved creep, and as a result he was returned to the factory for refinement.In this regard, a fundamental review of the layout needed a gun, although her material claims the commission did not have.These works have been performed by the №172 in the first half of 1948, and August 23, the commission of the Main Artillery Administration has once again considered the revised draft.However, this time the "Object 261" was rejected.Once again, the designers have changed the design of the plant №172 gun rather the machine.

Meanwhile, the Leningrad Bureau ...

While Permian again "conjured" over the instrument, in the cultural capital has almost everything was ready.EC-7 was already close to the conveyor production.As mentioned above, the engineers have adapted diesel engine for this tank;its capacity was 1050 hpAccording to specialists, "Object 261" was to reach a speed of 55 km / h and have a range of up to 300 km.The gun and the crew planned to be placed in the open light armored cabin.This option is completely ruled out participation in the ACS tank duels.But wheelbase artillery system left much armor, apparently, to unify with the JS-7.She had a thick armor of 150 mm to 215 mm."Object 261" it turned out rather heavy, his weight was 68 tons.When the work was almost finished, the government refused to produce tanks IS-7.So, despite the work done, the project has not been approved, and that ACS was published only as an experimental model.

World of Tanks: «Object 261»

Now back to the game "World of Tanks".Here, this gun mount technology developers carried to the tenth level, the maximum for the project.In the description of the object it is said that said the Soviet ACS has precise instrument, and high speed flight shells and excellent dynamics, however, due to the flat trajectory fire, defeating the purpose, located behind an obstacle, is very difficult.We investigate the "Object 261" on ACS 212A, the price of such a study is 273 000 gaming experience.Like all machines of the tenth level of the game, this art is a luxury, so does not need pumping.In the photo below you can see that is the "Object 261".

Hyde provided game developers

The help of the World of Tanks describes how to play this setting with the greatest efficiency.Regarding the choice of position, it should take into account the low trajectory of the projectile, therefore, where other ACS easily throws ammunition, our installation fall into the wall.Therefore it is recommended constantly seek out new places, from which it is convenient to fire, especially since the acceleration and maximum speed allows it to do so.Also here it is said that this city maps arte better to follow a group of his tanks and shoot enemies armor-piercing projectiles, then penetrated by 360 mm, and the damage - in 1100 HP.If ACS marred the enemy, it is best to immediately change the disposition;then competitors leave the "carrier" 261 th to "snack".Shooting should be based on the most powerful tanks, but if the choice is: finish JS-8 / ST-1, or inflict damage on the IC 7 / EC-4, it is better to stay on the first version.In addition, preferable to fire at medium tanks located in the open countryside, on a more serious than hiding behind obstacles.Given that the ACS is characterized by a low alpha-damage, it is preferable to use BB-shells, which, combined with high accuracy and breaks can cause serious damage to any tank.You can also use anti-regime - it provides a fairly high mobility of our subject, which is the "Object 261".

«World of Tanks" indicates a number of pros and cons of the artillery unit.Advantages:

- the fastest in the game to recharge level 10;

- sloping path is very convenient for the destruction of enemies in the opposite slopes;

- all the artillery of the ACS has the highest accuracy;

- very powerful BB-shells;

- high mobility.

Disadvantages:

- small ammunition;

- a small radius of flight of the fragments;

- small traverse;

- relatively little damage;

- flatter trajectory, which does not allow the shells flip through serious obstacles.
