We continue to clarify the upgrade of the T-72B3.
Start in the 1 part.
- Twin machine gun:
Coaxial machine gun unchanged - reliable FCT, PKTm. In any case, there is no data on tank versions of "Pecheneg" and "Pecheneg-2."
Photo 41: PKT machine gun.
Interested in the question of how much attention was paid to the reliable isolation of spent cartridges. As practice has shown, the rupture of the bag and their scattering on the conveyor AZ can lead to non-sugar effects.
Fully fall into a stupor when you see an open manual control gear lock ...

One flaw quite naturally forms another.
Commander has NO instruments capable of controlling and aiming. Savings on the installation of a minimum (TKN-4-01) resulted in the rejection of the remote LSD.
How smart is it necessary to be a person ordering in 2011, after all local wars, a variant of such an installation ??? True, I said very gently? It was not easy for me.
Good and efficient weapon practically idle idle. It can not be used while under rifle fire.
Not only does the commander literally give up control of the tank, giving himself the gunner and mechanic, not only does he risk like a daredevil for sure, but he also plays a circus show titled: “And why haven't you riddled me yet? I have been hanging around on stage a lot of time, performing before you a stupid dance called "Preparation of the ZPU" cliff "for shooting».
See for yourself:
- Tilt the door back onto the stopper.
- Put the inner shoulder strap with TKN-3 on the stopper.
- Remove the middle shoulder strap from the stop lock from the stop and rotate the installation towards the enemy.
(To accelerate, we shoot without using a sight, and we will assume that the box is already fastened, the tape is laid in the receiver, the fuse is off, the machine gun is cocked - this is how we violate the safety rules).
- Disconnect the cradle.
- Turn the vertical flywheel with your right hand, locking it with your fingers with the lever on the flywheel handle.
- With the left hand holding the extended lever, with a force we turn the device horizontally and stop it with the whole hand, pressing this lever down, and ...
Attention drum roll ...
Without changing the position of a single muscle (!!!) of the hands, with the fingers of the left hand, we press the lever of the electric trigger. If you do not reach the desired "shooter", then repeat the horizontal lead again.
Even a trained tanker will mess around long enough for him to be guaranteed and spanked several times. A newcomer will not be able to understand the intricacies of leverage at all, and he always lacks one, third, hand.

If for some unknown reason you remained alive, then you need to perform this procedure in the reverse order. Otherwise, the “Cliff” trunk will fly up to the heavens, and the average shoulder strap will dangle from side to side, respectively, you can forget about trying to see something through TKN-3.
As a result, the "cliff" of the tank was loved at the roadblocks, when armor was attached to reinforcements.
A competent tanker from such a machine gun will not let anyone on the effective range of fire from small arms. That's all his ability to use in the way in which he is now.
At the Tagil arms exhibition in 2013, a variant of the “urban tank” was shown, at which the commander's protective box was installed.
Photo 44: Protection commander for firing from the ZPU.
Until now I have been asking everyone: to which pursuit is this shell attached? Kind of like an internal epaulet with TKN-3. Otherwise it makes no sense ... The commander clearly has his hands and his back will fall off after an hour of torsion of this size of scrap metal.
Of course, such protection is better than nothing, but: how much is the total: TKN-3 + ZPU Utes (Kord) + barrel-shaped protection? This money is almost thrown to the wind.
Maybe all the same TKN-4C-01 and not so expensive? And maybe, finally, we will reconsider the doctrine of the use of portable weapons, re-qualifying it from anti-aircraft to auxiliary for personal protection from bearded lovers to carry a “seven” on their shoulder?

- Wonderful modernization of the entire main complex: gun + AZ + ammunition of increased power. Together, this significantly increases the tank's ability to accurately and quickly destroy the enemy.
- PKT, as always, taxis.
—ZPU is a complete disregard for the life of tankers and belittling the fire capabilities of the machine.
4. Change in fire fighting equipment
The system of fire-fighting equipment (PPO) 3ЭЦ13 "Hoarfrost" of the T-72B3 tank is a development of NPO Electromashina.
Photo 46: The composition of the kit PPO "Frost."
It is an automatic system for detecting and extinguishing a fire, ensuring the ESD mode under operating conditions.
Action: 2 multiple.
To extinguish the fires, there is an 4 cylinder with an extinguishing mixture “114B2 freon” and “13B1 freon”.
The system includes: automatic control unit В13, control panel and alarm system П13, ventilation control box КУВ11-6-1с, dynamic braking box К11. The notification of the system is made by 10 optical sensors OD1-1С and 5 with temperature sensors TD-1 (in the engine compartment).
Photo 47: layout of the 3ETS13 devices in the tank.
When the system is triggered, 90% of the extinguishing agent is ejected in a time not exceeding 150 milliseconds from the sensor signal.
The principle of the system is based on the extinguishing action of halocarbons, i.e. on the inhibitory (retarding) effect, which consists in introducing into the flame zone a negative catalyst for the oxidation reaction of hydrocarbons. The software system can be activated automatically or manually from the buttons on the control panels at the vehicle commander or the driver. In addition, the tank is equipped with two handheld carbon dioxide fire extinguishers, often referred to among tank crews as the “Hero's Dream”.
Nothing new in the software system T-72B3 is not noticeable. "Rime" was installed on armored vehicles since T-72BA (although I remember it perfectly in the second half of 90-x on T-72B). Put this equipment and T-90.
For 1989 cars of the year, of course, it is a novelty ... For those who doubt, a photo, where the characteristic contours of the 13 Pneumx control panel and alarm system of the Hoarfrost system are visible in the background. The 3, 13, 1 sub-indices are possible in 2EC11.
48 photo: OD1-1С optical sensor installed in the control compartment. Background PU PU system.
Previously, the T-72B was installed on the 3ATS11-3 system with 14-15 thermal sensors (without optical), three times a day with 3 cylinders filled with “114B2 Freon”.
Conclusion: This PPO is not a novelty, but it is undoubtedly better than the old 80’s standard models, which were replaced during modernization.
Identify internal changes in booking a car is not possible, and rightly so. Secrets - they must be secrets in Africa too. However, it is hard to believe in the production of works in this direction: to alter the tower and the building is not at all that easy.
Reservations turret T-72 refers to the "semi-active" type. In front of the tower are two cavities located at an angle 54-55 degrees to the longitudinal axis of the gun. In each cavity there is a pack of twenty 30-mm blocks, each of which consists of 3 layers glued together. Block layers: 21-mm armor plate, 6-mm rubber layer, 3-mm metal plate. 3 thin metal plates are welded to the armor plate of each unit, providing the distance between the 22 units mm. Both cavities have an 45-mm armor plate located between the bag and the internal wall of the cavity. The total weight of the contents of the two cavities 781 kg.
49 Photo: T-72B tank filler package with reflective sheets.
The constructions of non-explosive anti-cumulative dynamic protection contain, instead of a layer of explosives between the outer inert layers of a material with a high density, an inner layer of a chemically inert material called "filler", such as plastic, rubber, paraffin, or mixtures based on them. When a CS penetrates through a "non-explosive" element, a diverging shock wave is formed in the filler, under the influence of which the material of the outer layers surrounding the point of impact is accelerated. Due to the rapid decrease in pressure in the HC, the acceleration of the outer layers is localized near the point of impact. Despite the limited size of the zone in which the accelerated movement of the outer layers of an EDS with an inert filler occurs, a decrease in the depth of the armor-piercing effect due to the destruction of the high-speed part of the CS can reach 65-70%.
Abroad, this type of protection is classified as NERA (non-energetic reactive armor).
Photo 50: One of the niches with installed packages of tank filler T-72B.
Seeing for the first time the external protection of the T-72B3, you involuntarily fall into a complete tailspin ...
Did TTZ exactly make up the General Staff of the Russian Federation? Or maybe the enemies are warning in advance?
Let's try to consider without a mat. Why is there no "Relic"? Or is it not the end of the year 2013?
Universal complex DZ "Contact-5" was adopted in the middle 80-s. What does it mean?
Photo 51: Installing remote "Contact-5" on T-72B3.
Why is the fighting machine protected worse than the old T-72B?
WE HAVE NOT HAVE A BITTERY EXPERIENCE AT ALL RECENTLY?
No matter how paradoxical it may sound, the protection variant “Contact-1” of the T-72B tank looks ... somehow preferable.
Photo 52: Installing remote "Contact-1" on T-72B.
And this is not said for the sake of a red word.
Many tankers, who happened to "work" on orders in different "tmutrakani", would prefer a CONTINUOUS protection with old DZ blocks than any supernovaled new (even "Relic") installed in places and ... in chunks.
The fact is that there are not “Javelins” at every corner, but all sorts of bearded men who consider the G7 to be their national weapon - at least a dime a dozen. You can even stumble about them in some parts at every turn.
Why is it completely open in frontal projection?
On the one hand, they dismantled the "Moon" and ... forgot to install the DZ block? From the PCT embrasure to the nearest block there is still a football field of frontal armor.
On the other hand, the hole is left in favor of the comfort of the driver? What a caring we GSH.
But for some reason on other models of combat vehicles do not care so much. As on the same "Slingshot", for example, or T-90. So it is possible?
Photo 53: T-90 with DZ "Contact-5" around the gun mask.
Why are T-72B3 DZ blocks placed with such disregard?
Photo 54: Placing DZ blocks on the T-72B3 tower.
And the matter is not even in the holes between the blocks, but in the openness of the tower shoulder strap, which on T-72B was covered with an additional belt of “Contact-1” blocks.
Photo 55: T-72B turret protection (Army of Belarus).
And even with such protection, they hung and wound up anything:

Why is the T-72B3 shoulder strap open to all winds?

Why can not make the most complete protection?
58 Photo: Frontal protection option for the T-90 turret.
Although even on the T-90 the shoulder strap is protected worse than on the T-80U.
Photo 59: T-80 and T-90 turret shoulder strap protection scheme.
In the defense of the tower on the sides and back of the T-72B3, as always, they control the long-suffering boxes of spare parts.
Photo 60: Side protection of the tower and the hull T-72B3.
Photo 61: Terrible. January 1995. The tank commander was killed.
Again, we will independently sculpt protection from what is at hand?
Photo 62: Side protection of the tower from the drawers of the RAV tank T-72B near the village of Komsomolsk. The lattice screen with a raised OPVT pipe is clearly visible.
Protection of the roof of the tower - a separate issue.
Why was it so on T-72B?
63 photo: T-72B tower roof protection.
Why it became so?
64 photo: T-72B3 tower roof protection.
The idea of the GSH is not clear ...
- If this is a defense in a large-scale war, then it will not help in any way against cluster munitions aviation and MLRS large caliber WTO regime. By the way, the anti-nuclear bullet also disappeared.
“If this is protection from bearded men with the G7, then they ... will just laugh while looking at this protection!”
They searched for unprotected places.
Photo 65: Grozny. January 1995. Falling from the top floor of the building into the commander's turret T-72B. The commander died.
This car could only be stopped like this ...
THIS MUST NOT REPEAT.
Protection of frontal armor corps pleases. And the side? There is no her. Photos of 60 and 66.
Photo 66: Side protection body T-72B3.
In the protection of the sides of the case at the head of the corner stands rubber screen. Even without boxes DZ "Contact-1".
Based on the realities of applications mounted DZ (city), we can draw some conclusions:
The contact of the case with a non-combat obstacle:
- Rubber fabric screen with boxes DZ well bends around minor obstacles WITHOUT damage to the protection itself.
- Frame hanging DZ demolishes.
- Heavy screens are in place.
- Rezinotkanevy screen pulls away cell by cell, if they are not fixed among themselves.
- Frame hanging demolishes.
- Heavy screen stands still.
- Rubber in the trash.
- Skeleton in twist.
- Heavy screen pulls down one span.
Why on T-72B3 not put side protection, as, for example, in the serial BMO-T?
Photo 67: Lateral protection BMO-T. The parade of troops in Yekaterinburg.
Protection rear projection remains the greatest misfortune of serial machines. It seems that the tanks never turn their backs on the enemy ... You tell me about this “bearded” with the “seven”. He is just waiting for this, because THIS is his bread.
68 Photo: Rear Projection Protection T-72B3.
And where is the defense? Barrels are removed before the "work". All naked. Why it is impossible to put lattice screens, like in BMPT or a variant of a city tank?
Photo: 69. Protection of the rear projection of the version of the "urban tank" modifications T-72.
Creating a simple circular defense is not a flight to Mars of a nuclear-powered submarine with a ballistic missile on a caterpillar. Everything is much and much easier. And inexpensive. The question is why do we do this? Almost a rhetorical question, if his tankers are more than 20-years old (in my spirit) are asked.
The T-72B3 protection conclusion is very emotional. Because it is not clear what interferes with hanging “boxes” with “Contact-5” or “Relic” on the ALL surface? The total mass of equipped DZ blocks? But it seems there is still a sufficient resource of modernization without significant changes in the hardware. And even with the B-84 engine, power density does not suffer.
Conclusion on protection: I would not send my tank crews to “work” without boiling additional DZ boxes and grids. With the involvement of, respectively, BREM and with the agreement with the deputy technologist and ... "chm.shnikami."
6. Engine, transmission and chassis.
Almost no changes.
B-84-1 left in place. B-92 is not set. Tankers, accustomed to the GTE, are shocked by all engines without distinction, but diesel drivers are frankly happy. The 84 is time tested and reliable. The troops know how to handle it. B-92 needs to collect claims from army trials.
And so, this is the same upgraded B-46-6. He has a large family: В-46-2С1, В-46-4, В-46-5, В-46-5М, В-84, В-84-1, В-84М, В-84М, В-84-1, В-XNUMXМ, В-XNUMXМ, В-XNUMX-XNUMX, В-XNUMXМ, В-XNUMXМ, В-XNUMX-XNUMX, В-XNUMXМ, В-XNUMXХ .
Photo: 70. Engine B-84 cm horsepower 840
Once moved the same, then the transmission is really the same. Guitar unchanged, BKP without amplification and an increase in the number of friction pairs in the friction controls. Bearings support sun gear are the same. The radiators and the friction clutch are the same.
Replaced caterpillar with a serial RMSH on a caterpillar with parallel RMSH. They are currently installed on both the T-90 (with 1996 g.) And T-72BA (with 2000 g.) When upgraded with replacement of the corresponding chassis parts in order to operate this track.
Whether the entire undercarriage was upgraded to the level of T-72BA (there were tangible changes in the installation variant of the B-92C2 engine) is unknown.
Photo 71: Caterpillar with parallel RMSH.
No change except the caterpillar and the necessary elements of the chassis.
Disappointment. Over the 20 years, almost nothing has changed with the modernization of the T-72. (Personal opinion, some talk about both 25 and 30 years of experience).
B) Objective (in moderation):
- Impressive modernization of the whole set of capabilities of the main staff under the gunner’s control: an upgraded tank gun with improved shooting parameters, a new aiming complex, an upgraded automatic loader with the possibility of firing with the newest shots.
- It depresses the leveling of these qualities by an almost blind commander.
It's not a secret for specialists that hitting a target ... is much easier than detecting and classifying a danger in time. The commander of the T-72B3 is unable to do this.
- There is hope about bringing to the mind installed communication systems.
- PPO "Frost" is not bad, but 2-multiplicity of application is not enough, it is desirable to increase, as well as the number of cylinders.
- Complete shock from the protection of the hull and turret.
- The engine, transmission and chassis (except for the harp with RMSH) - the same as many years ago.
Overall impression - began upgrading the machine and ... did not finish it. Moreover, further improvement of the machine does not require additional serious money.
At the exhibition of armament, military equipment and ammunition Russia Arms Expo (RAE 2013) a full-scale model of KAZ Arena-E mounted on T-72B3 was presented. Modern and costly achievements of the military industry are again side by side with ... TKN-3 commander and an open ZPU ...
Photo 72: T-72B3 with KAZ "Arena-E."
The concept of the General Staff in relation to the existing fleet of tanks in the Armed Forces of the Russian Federation is visible:
- Reliance on the existing park T-90.
- Liquidation of machines of the T-80 family.
- Upgrade the T-72 to the level T-72B3.
T-90 around 500 pcs.
The rest of the niche will occupy T-72B3.
And it will be BEFORE the arrival of "Almaty".
But Armata is still at the design and testing stage.
In order for it to go into series, a long-term cycle of state and military tests is necessary. And only after that it will be possible to talk about serial deliveries of the volumes that the military-industrial complex will be able to provide and pay for the Defense Ministry under the rearmament state program.
So ... We are entering the XXI century, before entering the linear armored units and units, "Armaty" with ... the current version of T-72B3?
Tankers are not critics. “Fuel Oil” (of my generation and many others) thinks about HOW you can accomplish the task and order on available military equipmentwhile maintaining the lives of fighters. Tankmen of linear units do not dream of future promises and do not wave the booklets of the newest tanks. They serve in the army TODAY on the technique that is in the army. And right now.
