Is 3 with mz level of battles. Crew skills and abilities

Soviet heavy tank VIII

Everyone’s favorite 3ka, and even with standard shells in the form of sub-calibers, oh Wargaming, what are you doing to us?

Naturally, a full-fledged level of fighting, but what did you want? After all, Grandfather-3 has always been random, it was, is and will be, we hope. But there are still differences, and what is the difference between a regular IS-3 and a 3 with a loading mechanism. Some people will think, wow, a drum scoop? But no. More precisely, this was originally planned in 1956-1957, the turret was changed, which is why some called him the bald grandfather, the crew was reduced to 3 people, but the car remained in the sketches, but it is present in the game.
So, let's go in order. Reservation. We have absolutely identical armor to the upgraded IS-3, even 30 mm. the stripe on the roof remained. Here
nothing changes. In terms of dynamics, plus or minus, the same thing, the difference is insignificant. Well, let's move on to what really distinguishes these two tanks. Armament. The IS-3 with MZ has a sub-caliber penetration of 221 mm. and cumulative 270 mm. with an alpha strike of 390 units. At the same time, the rate of fire is higher than that of a conventional IS-3 and, accordingly, the DPM is higher. 2000 versus 1700 HP per minute, in standard terms. Without rammers, ventilation, military brotherhoods, and so on. With the above things you can still increase the rate of fire. A minor drawback is that it has a crew of three people, so third-party tanks will not be able to fully upgrade the crew. But the car is clearly worthy of attention. Without exaggeration.

Pros:

+ the frontal armor plate is made of the “pike nose” type;
+ good turret armor;
+ good one-time damage;
+ armor penetration acceptable among TT-8.

Minuses:

- weak dynamics;
- low accuracy;
- long mixing;
- mediocre ammunition size;
- poor visibility;
- commander overload.

Regarding profitability. It is possible to farm on this machine, and even most likely necessary. Cumulatives will not always be used, so you can bring quite a lot of silver.
Good luck on the battlefields!

It was assumed that the newest IS-3 8 would form the basis of the Soviet tank forces in the immediate post-war years. Therefore, despite the end of hostilities, their serial production continued at a high pace - in June, July and August 1945, ChKZ produced 250 vehicles each, in December it produced 275. However, it soon became clear that the IS-3, and other tanks, were being developed During the war years, they are not very suitable for service in peacetime. The reliability and service life of the mechanisms and assemblies of these machines turned out to be very low, although it was planned to operate them in peacetime for years, and not for a relatively short period - several weeks (before their destruction in battle), as was the case during the war.
At the very beginning of their military service, the IS-3 tanks showed a number of shortcomings that were the result of design miscalculations and errors made during the design. In particular, the design of the armored hull, while providing a high level of projectile resistance, did not have the necessary operational rigidity. Finally, the military’s faith in the IS-3 was undermined by the information that during one of the control shelling of the tank at the training ground with 100-mm armor-piercing shells, after hitting the rib of the frontal part (“pike nose”), the hull burst at the welds and practically fell apart - the machine was completely disabled. As a result, in 1946, production of the IS-3 was discontinued, and all existing tanks underwent modernization under the program for eliminating design deficiencies (DCN).

During operation, damage to the housing in the MTO area, gearbox breakdowns, engine failures, etc. often occurred. The work of organizing the repair of the entire fleet of IS-3 tanks turned out to be complex and painstaking. It was necessary to develop documentation for dismantling the tanks, measuring and inspecting the main components and parts removed from the vehicles, for rejecting those that were out of order, as well as for their restoration or repair. Almost all OKBT departments of the Kirov plant were involved in the complex of special works.

They were coordinated by experienced design engineer V. Kozlovsky. By the end of 1951, more than 120 multi-page instructions for restoring the main components of the tank were issued here.

In 1948 - 1952 All IS-3 tanks were redesigned and modernized according to the UKN program at the Kirov plant. First of all, the turret plate and engine mounting brackets were strengthened, which increased the rigidity of the hull. We improved the transmission and chassis - improved the design of the main clutch, final drive seals and track roller bearings. The gearbox mount was changed, which reduced the resulting misalignments of the engine and transmission elements. Instead of a manual oil pump, an electric MZN-1 was installed. To ensure more stable radio communications, radio station 10-RK was replaced by another - R-113. As a result of all the innovations, the mass of the tank increased to 48.8 tons versus 45.8 tons for the IS-3 model of 1945.

Despite the extensive list of alterations and large amounts of money spent, the cost of upgrading one vehicle under the UKN program cost 260,000 rubles. - the operational characteristics of the tanks were never brought to the necessary requirements.
At the end of the 1950s. IS-3 again underwent modernization, after which they began to be called IS-ZM. Compared to tanks produced in 1945 - 1946. they received a more advanced engine, heating system, transmission units and chassis components; The rigidity of the body was further increased. The main objective of the modernization was to bring the IS-3 up to the level of combat vehicles of that period and the maximum possible unification of its components and assemblies with modern tanks.

To increase the rigidity of the bottom of the hull, a plate made of armored steel was welded under the gearbox, as well as strips that prevented the covers on the bottom of the tank from breaking when hitting the ground. The sealing of all armor plates on the rear hull, as well as the hatch covers of the middle flap, has been improved. We installed slats on the stern sheet and braces on the bottom. The engine pedestal was also strengthened
due to the installation of braces, gussets and planks.

The bearing units of the road wheels and idler wheels and the oil seals were strengthened.
The design of the wings mounted on the body has been changed. For greater rigidity, stampings (ridges) were made in the sheets of the front and rear wings. Folding hinged fender liners were added to the front fenders, and sheets of rubberized fabric were attached to the rear fenders, protecting the body from splashing with dirt.

An additional nighttime infrared driver's device, TVN-2, was introduced, which was installed instead of a daytime observation device or on a special stand when driving camping. Instead of the MK-4 viewing device, the tank commander had a TPK-1 device installed in the rotating hood of the hatch cover, which had a five-fold magnification and a field of view of 30°. The rotating cover of the commander's hatch itself received additional seals.
The DShK anti-aircraft machine gun was replaced by the modernized DShKM, and the DT machine gun by the DTM. Since 1960, the ammunition load for the coaxial and anti-aircraft machine guns was reduced to 945 and 250 rounds, respectively.

The ammunition stowage has undergone minor changes. Since 1953, it began to include 11 rounds with an armor-piercing tracer projectile and 17 with a high-explosive fragmentation grenade, 300 rounds for anti-aircraft and 2000 rounds for coaxial machine guns. The ammunition racks, which contained only armor-piercing shells, were painted black, the rest - steel gray.

There were 23 shells on the shelf in the turret, and five in the fighting compartment of the tank. The cartridges with charges were placed in charging packs also in the fighting compartment of the tank and also in the control compartment. To the left and right of the driver’s seat were stacks of seven cartridges each. On the right side of the gun there was a stack of five cartridges; it was suspended from the central column of the rotating contact device. On the right and left, two sleeves were attached to the inclined side sheets of the hull, and two more were attached to the engine bulkhead. Three cartridges were placed on the floor of the fighting compartment.

Instead of the V-11-IS-3 engine, they installed the V-54K-IS engine with a maximum power of 520 hp. at 2000 rpm.
The Multicyclone air cleaners were replaced with VTI-2 with two degrees of purification and ejection removal of dust from the first stage.
A new oil tank with a heat exchanger and a defoamer was installed in the lubrication system. Cooling of the gearbox lubricant was also introduced.
Since 1960, the fourth external fuel tank (left rear) was excluded from the fuel system - oil reserves were now poured into it. But they provided mounts at the stern for two 200-liter fuel barrels, the use of which increased the highway range to 450 km.

A NIKS-1 heater with forced liquid circulation was built into the cooling system.
A two-wire emergency lighting circuit was introduced in the electrical equipment. We installed two headlights: FG-127 visible light with a light-masking device (left) and FG-125 (FG-100) with a light filter (right). An external launch socket was installed at the stern. Direct-acting instrumentation was replaced by electric ones.


Tactical and technical characteristics of the IS-3M tank

Since 1961, the radio station R-123 and TPU R-124 began to be used on tanks.
In 1963, IS-ZM tanks underwent design improvements. The stability of the alignment of the engine and gearbox was increased, more advanced units, components, equipment and devices used on production vehicles were installed.
The tanks were equipped with chemical protective equipment - gas masks, protective stockings and gloves, a decontamination kit - for operations in contaminated areas; in case of underwater driving - insulating gas masks IM-46.
The ammunition rack has also undergone some changes - it has become possible to mount charges with a burning casing. Accordingly, they installed a reflector for ejected pallets when firing with them.

Poking around in the supertest client usually bears fruit. This time was no exception. Meet the IS-3 with a loading mechanism!

Upd: there will be no drum on the tank, but only an increased rate of fire due to a special loading mechanism and the location of the ammunition rack.

Information about the tank was received by the program:


The tank was developed as a graduation project from the Academy of Armored Forces from 1956 to 1957. It was proposed to place the ammunition rack in two rows, so the turret was changed for these needs, and the crew was reduced to three people (the loader was removed as unnecessary).

Work stopped at the sketch stage.

Schematic representation of the tank loading mechanism:

Comparison with conventional IC

The table shows the different tank values. The screenshot shows sub-caliber shells, let's compare them. The data is indicated without taking into account the effect of additional modules and equipment.

The model with a loading mechanism has a gun very similar to the D-25T (not the top-end gun of a regular IS).

Continuing to look at all the glitches in our random matrix, I came across such a rather curious tank as IS-3 with MZ(Loading Mechanism). Who is this? Despite the name, you won't find a drum in it.

The tank, of course, should be compared with the ordinary IS-3, which we all know so well. What do we know about the regular IS-3? This is the most versatile, simple, comfortable tank that forgives many of the owner’s mistakes, is not fussy about skill, and does not require serious support from medium tanks. It would seem that the IS-3 MZ under consideration should generally be an ideal tank: all the same imbalance, only in the packaging of a premium tank, what does farming with comfort essentially mean?


Parameter overview

Firepower. The legendary BL-9 is inferior to the D-25TA gun (a similar gun to the IS-5) of the newly-made IS only in rate of fire (4.51 versus 5.13) and in penetration by “golden” shells (265/270, due to the presence of the IS-3 gun MH of cumulative projectiles), while winning in penetration with basic and high-explosive projectiles (225/68 versus 221/61) and accuracy (0.4 to 0.46). The rest of the indicators are similar. The IS-3 MZ gains its 319 points thanks to the best DPM, but given its accuracy and penetration, it is actually much more difficult to implement than it seems. 1:0 in favor of IS-3

Vitality. All indicators are similar, with the exception of strength points - 1500 for the IS-3 and only 50 more for the competitor. Paying attention to the hull, it is easy to notice that the turret of the IS-3 MZ has a smaller diameter, which makes it more invulnerable when attacked from the sides. 1:1, IS-3 MZ equalizes the score.

Mobility. With the IS-3 weighing 49.1 tons, which is 0.6 tons less than its competitor’s weight and engine power 700 versus 520 hp, we get a specific power of 14.26 versus 10.46 hp/t. The turning speed is also better for the IS-3: 31.29 deg/s versus 29.33 for the non-clone. The round would have been won dry if it weren’t for the disappointing maximum speed: 38 km/h versus 40. This is explained by the characteristics of the cars’ soil resistance. 2:1, IS-3 takes the lead again.

Stealth. There’s not much to say about it, given that we’re talking about heavy tanks, but the clone has something to brag about: standing, the coefficient is 6.84% before the shot and 1.3% after, and while moving 3.42% before the shot and 0.65% after. The familiar IS is not much worse with this: standing 6.75% before and 1.21% after the shot, while moving - 3.37% before and 0.61% after the shot. I think this point should not be taken into serious comparison: heavy tanks have no right to stand in the bushes.

Observation. The range of the IS-3 is 350 meters, that of the IS-3 MZ is 358. The communication range of the classic is 730 meters, the clone is 735 meters. These indicators allow the IS-3 MZ to even the score. 2:2.

Conclusion

It turns out that, regarding certain parameters, the tanks are identical? As it turned out, with the same concept of combat, individual indicators, their shortage or excess, are not felt on the battlefield, unless we talk about the weapon.

After spending 20 battles on each of the tanks, I noticed the lopsidedness of the clone’s gun and the unprofitability of the original. So, this tank can only be bought if you don’t have any premium tanks in your hangar at all. If this is not the main thing for you, the classic version of the tank will be much better.


IS-3 with a Loading Mechanism - how cool this tank name sounds. When yesterday in battle on an AMX 50 100 I met this IS-3 MZ, I thought this was a meeting of drummers. Let's see what the vaunted Soviet alpha is capable of when she's on the drum. But how wrong I was

After all, he doesn’t have any drum)))). This was a big disappointment, I thought they released a really cool premium tank. But for the IS-3 with the Loading Mechanism, they simply removed the loader and installed a loading magazine. Reloading is faster than the classic IS-3, only 1 second. In general, it’s sad: recourse: But it sounds so beautiful, apparently sales are very bad if they have already started using such marketing techniques. Let me remind you that this is a new Soviet premium heavyweight of level 8. BUT it’s not worth buying, it’s better to actually use the IS-6 or FCM if you need to farm.

  1. Long mixing - sooooo long;
  2. Oblique weapon;
  3. Very slow and clumsy.

Where to shoot the IS-3 MZ

Here everything is as always - we sew according to the usual pattern, just like the pumped-up analogue of the IS-3. In the screenshot I drew where to pierce the IS-3 with a loading magazine.
