Recently I came across some work done by tanknutdave explaining the evolution of T80 and I decided to post the information here. A lot of members says that some of our t80ud have advanced features of the t84 which we can discuss later on. I will also post the link of the yugoslavian m84 due to the fact that they as well as the ukranians have helped us in manufacturing the alkhalid. Basically its just an info pool/dedicated t80 discussion thread









The Russian T-80 Series


When the T-80 entered service in the former U.S.S.R in the late 1970′s, many NATO countries confused it as the T-72. It did have the same self loading carousel that reduced the crew size down to three men as used in the T-72 as well as the use of reactive armour on the turret, but mechanically it was a different tank.

The T-80 started out as an improved version of the highly successful T-64 and was designed and produced by the SKB-2 design bureau at the Kirov arm’s factory in Leningrad. One of the design improvements was the introduction of a gas turbine engine (the GTD-1000T and GTD-1000TF) and the T-80 was the first tank in the world to be fitted with one. One of the other improvements made was to the suspension system by using components from the T-72′s. The T-80 is a much smaller and lighter MBT than that of NATO countries MBT’s at the time and current one’s, weighting only 46 ton’s on average.

In 1985 the T-80 went through a major upgrade program at the SKB-2 arm’s factory in Leningrad. It received a new type of reactive armour called “Kontakt-5″ and is able to withstand modern armour-piercing fin-stabilized discarding sabot rounds. Its former secondary weapon, a remotely controlled commanders MG was replaced with a pintle-mounted one and fitted with the Brod-M deep wading equipment. The biggest change was the replacement of the old gas turbine engines, which drank fuel at an alarming rate and limited its operational distance. It was fitted with the GTD-1250 three-shaft engine, with two cascades of turbo compression producing 1250hp and with its lightweight it has earn’t the nickname as the “flying tank” and was redesignated as the T-80U.


Whilst the T-80U program was happening, the Morozov Design Bureau in Ukraine was developing a diesel-powered version, designated the T-80UD (“D” for diesel). It took on all the main improvements of the T-80U with a few exceptions such as keeping the secondary weapon, the commanders MG as remotely controlled. It is also able to fire from its 125mm 2A46 smoothbore main cannon the improved wire guided 9M119 Svir missile and of course not using a gas turbine engine. Instead it was fitted with a 1000-hp 6TD-1 6-cylinder multi-fuel two-stroke turbo-piston diesel engine, which gives it a far better fuel efficiency and a longer operational range than T-80′s with turbine engines.

Between 1987 to1991, roughly 500 T-80UD tanks were built at the Ukrainian Malyshev Factory, but when the wall fell in Germany and the U.S.S.R broke up, 300 of them were still at the factory and are more commonly seen in the Ukrainian Army rather than in the Russian Army.

The future of the T-80U & T-80UD is turbulent. It has had many upgrades and versions built. The Russian Army are moving towards using the T-90 after the T-80′s high fuel consumption and poor combat performance in the Two Chechnya Wars. Exports of the T-80UD have been slow, mostly due to Russia not supplying The Ukraine with turrets and technology, which was resolved by the development of domestic components. As a result Pakistan ordered over 300 of them between 1997 to 1999. With the development of domestic components and independence in tank building the Ukrainians have now developed an improved version of the T-80UD, designated the T-84 for export. The T-80 series are still in service with a number of countries including: Belarus, Cyprus and Russia.

T-80: the original production model, which was only produced in very small numbers.
T-80B: was the first mass produced variant.
T-80BK: was the command variant of the T – 80B. It was equipped added communications equipment.
T-80BV: was the variant first fitted with Explosive Reactive Armour.
T-80BVK: was the command variant of the T – 80BV. It was equipped added communications equipment.
T-80U: was the variant that had the biggest overhaul. It saw changes to the secondary weapons, new engine decking, new armour, vision equipment and commanders’ equipment.
T-80UD: saw the replacement of the gas turbine engine with a diesel.
T-80UK: was the command version of the T – 80U.
T-80UE: was the same as the T – 80UK but without the command equipment. It did retain the Shtora-1 system (IR jammer to defeat guided missiles).
T-80UM: saw the replacement of the diesel engine to a new 1250hp gas turbine.
T-80UM1: has the Shtora-1 system fitted and the gas turbine beefed up.
T-80UM2: was fitted with a new cast turret.
BREM-80: is the T – 80′s armoured recovery vehicle.

The Ukrainian T-80UD Main Battle Tank

Being a member of the former Soviet Union & a key industrial state, Ukraine built a number of tanks under licence during the Cold War period and one of these was the T-80. Seeing the problems the gas turbine engine caused for the Russian T-80U, the Ukraine further developed the vehicle (under the leadership of Nikolay A. Shomin) based on the Izdeliye 476 tank and the running gear of the T-80.
In 1985 production begun at the State Enterprise Malyshev Plant (now known as Kharkiv Morozov Machine Building Design Bureau AKA KMDB) of the T-80UD (though a large numbers of the components were supplied by Russia), the key difference being the replacement of the gas turbine with a diesel engine, hence the ‘D’ in its re-designation.

The new engine is the multi-fuel two-stroke turbo-piston 6TD-1 6-cylinder diesel, which generates 1000hp. It provides an increased range over the T-80U. The air inlet for the new engine allows air to be ducted from the least dusty part of the vehicle and the two parts to the air filtration system, the centrifugal pre-cleaners and the air cleaner casing, aid the vehicle in water fording to a depth of 1.8m (5m with fording equipment) and further increase its operational range in hot climates up to 1000km without the need to change filters. The top of the engine compartment is fitted with special heat insulation to reduce the heat given of by the engine, thus reducing its thermal signature.

The suspension is torsion bar which is covered with a skirt and the forward part is under ERA armour. To reduce dust kicked up by the vehicle, a large rubber matt is hung at the front of the vehicle. The vehicle has as standard, a very basic dozer blade so it can dig its self a scrape to lie up in, within 15-40 minutes depending on the type of ground. Anti-mine equipment can be installed, such as the KMT-6 plough-type system and KMT-7 roller-type system. The range of the vehicle can be extended with two additional fuel drums at the rear of the vehicle.

The vehicle uses composite armour and ERA in order to keep the weight of the vehicle down. The vehicle has a standard NBC system and fire detection/suppression system.

The main cannon is the 125mm KBA3 smoothbore cannon with a cal length of 48 and is fitted with a thermal sleeve and fume extractor. The cannon uses two-part munitions and can carry 45 rounds (APFSDS, HEAT & HE-FRAG), 28 of these are kept in the vehicles autoloader, reducing the crew to three.

The vehicle is equipped with a guided missile system. A laser guided, tandem charge, ATM can be fired from the main cannon with an effective range of 5000m. It’s reported to be able to engage hovering helicopters and concrete emplacements.
Russian tank cannons and their derivatives have a much poorer accuracy compared to Western tanks, hence the added ATM capability to increase the vehicles lethality. Some say it’s the quality of the main cannon, whilst others say the quality of the tank rounds are poor, or both.

The vehicle is able to generate its own smoke screen by injecting diesel fuel in the engine exhaust and is also equipped with a bank of four electrically operated smoke grenade launchers on either side of the turret.

For close encounters, the vehicle has a coaxial 7.62mm MG (controlled either by the commander or gunner) and a 12.7mm MG on the commanders cupola, which can be used in the anti-aircraft role. It can be elevated from -5° to +70° and traversed through +/-75° to the right and left of the vehicle longitudinal axis, or through +360° together with the turret. It can be controlled by the commander from within the vehicle, limiting his exposure to close quarter fire.

The vehicle has a modern computer fire control system and sighting equipment:

1V528-1 ballistic computer – uses inputs from the sensors measuring tank speed, crosswind speed, target range, and course angle, will other information has to be manually inputted such as ambient air temperature, charge temperature, barrel wear, ambient air pressure. It is also able to calculate when the high-explosive fragmentation projectile with controlled detonation should be detonated over the target. It also has fire gating capability. This means the main cannon will only fire when the misalignment between the line of sight and the gun bore axis is within pre-determined limits, after the gun firing button has been pushed. The fire gate size is adjusted when calibrating the fire control system after installing it in the tank.

Gunner’s 1G46 day sight, gunner’s TO1-KO1E night vision system – the sight is stabilised for line of sight and incorporates a laser range-finder and a missile guidance capability. For export models option, the Buran-Catherine-E thermal imaging sight can be fitted.
Commander’s PNK-4S observation and sighting system – the sight is stabilised and has three channels: a day unity vision channel, a day channel with magnification of x8 and a night channel with magnification of 5.4x.
PZU-7 anti-aircraft sight & 1ETs29 anti-aircraft machine gun mount control system – Used to control and engage the 12.7mm MG against hovering anti-tank helicopters.
The Ukrainian Army of 2005, have 271 T-80UD’s and is also in service in Russia.


Pakistani T-80UD

With the collapse of the USSR, Ukraine ‘inherited’ a stock pile of 300+ T-80UD’s which were left at the Ukrainian factory. In 1996 Ukraine signed a deal to sell 320 of the vehicles to Pakistan. Some deliveries were made despite objections from Russia, who claimed the vehicle was in fact a Russian vehicle and refused to supply the Ukraine the parts to modernise the tank to the agreements promised standard. How ever the Ukraine had been developing their first tank to rely almost completely on indigenes parts, the T-84, so used parts from that vehicle to complete the production and delivery to the Pakistani Army in 1999, totalling 320 vehicles.

The following key support vehicles can also be supplied to provide the T-80UD MBT with technical and logistic support during its operational life:

armoured repair and recovery vehicle (based on the T-80UD chassis)
armoured vehicle-launched bridge (based on the T-80UD chassis)
tracked carrier with a carrying capacity of 12 t (its main sub-assemblies are similar to those of the T-80UD)
various tank maintenance mobile workshops (based on the chassis of cross-country vehicles)

The T-80UD design has now been surpassed with the T-84.

BALLISTIC PROTECTION
Main armour protection multi-layer (composite) - anti-projectile, combined, multi-layer, against penetration of HEAT and APFSDS projectiles (adapted for installation of explosive reactive armour array)

Built-in anti-tandem-warhead explosive reactive armour (BATW-ERA) - intended to increase the tank’s level of protection against kinetic energy (APFSDS) and chemical energy ammunition (HEAT, HESH, HEP), including ammunition with tandem warheads.

The armour protection fitted with BATW-ERA ensures protection against:

1. Hand anti-tank grenades, hand-held and stationary grenade launchers and recoilless guns (including ammunition with tandem warheads)
2. Anti-tank missiles of TOW-2, Milan and Shturm-S type
3. HEAT projectiles fired by 125 mm tank smoothbore guns
4. APFSDS projectiles fire by 125 mm and 120 mm tank guns
5. The BATW-ERA array consists of glacis module and side skirts installed on the tank hull, as well as modular elements placed on the outer perimeter of the front and side surfaces of the turret and containers installed on the turret roof.

The Nozh explosive reactive armour elements installed in special niches snap into action when hit by all types of hollow-charge warheads and sub-calibre armour-piercing projectiles.

The Nozh explosive reactive armour elements of the BATW-ERA do not detonate when hit by 12.7 mm bullets, 30 mm armour-piercing projectiles and shell fragments. The Nozh explosive reactive armour elements do not require any maintenance and are safe to deal with.

The Nozh explosive reactive armour elements are stored in containers or on the tank in heated premises or in the open air under a shed protecting them against precipitation and solar irradiation at temperatures from -50 to +55 degrees Centigrade. They can also be stored under the conditions of high humidity (100%) at temperatures of up to +35 degrees Centigrade.

The Nozh explosive reactive armour elements retain their qualities for 10 years, including storage in field conditions for up to 5 years and use on the tank for up to 3 years if the requirements for use, transportation and storage are met.

It takes the tank crew 2.4 to 2.6 hours to prepare the BATW-ERA array for combat operation within without the need to use any special contrivances (to do this, only the explosive reactive armour elements are to be installed).

Anti-mine protection

The anti-mine protection makes it possible to preserve the combat readiness of the crew and operability of the tank’s interior equipment in case an anti-tank mine explodes under the tank track (up to 10 kg TNT equivalent) or under the tank driver’s compartment bottom plate (up to 4 kg TNT equivalent).

Optronic countermeasures system

To improve the tank protectability, the Varta optronic countermeasure system is integrated in the tank.

The optronic countermeasure system provides:

1. Confusing of the guidance systems of ATGM by putting out laser jamming covering the horizontal plane of ±18° relative to the main gun tube and ±2° in the vertical plane.
2. Jamming of the ATGM guidance systems that use laser illumination of targets, semi-automatic laser guided homing projectiles as well as artillery systems equipped with laser range-finders by activating the remote fast-deploying aerosol screens in a sector of ±45° relative to the main gun tube
Optronic jamming station.

Aerosol screen laying system:

Mode of operation – Automatic, semiautomatic, manual
System reaction time in auto mode – less than 0.5 s
Qty of launchers - 12
Grenade caliber – 80 mm
Screen laying range – at least 50 m
time for laying the screen - not more than 3 s
effective screen duration - time 60 s

Crew’s collective protection system

The system ensures protection of the crew and interior equipment against effects of nuclear explosions, radioactive substances, toxic agents and biological warfare agents, as well as detection and suppression of fires in the crew compartment and power pack compartment

NBC protection system

PRHR-M1 radiation and chemical agents detector.

PRHR-М1 (RCAD) is designed for continuous check-up, detection, signalling and control using actuators of protection means:

•During intensive gamma- radiation (nuclear blast)
•During gamma-radiation on the contaminated terrain followed by measuring the doze of radiation
•During detection of poisonous vapors in the air as a result of enemy actions

The instrument provides light and audible signals in case of detection poisonous agents in the air or gamma-radiation on the terrain as well as it generates commands for switching blower on and shifting over the valve of filtering ventilation unit (FVU) in the filtering position.

The instrument provides light and audible signals in case of detection powerful gamma radiation as well as commands for engine shutdown, shifting over the valve of FVU in the filtering ventilation mode, switching off the blower if it was on, followed by switching it on in 30 to 50 s.

The instrument provides checking its electrical circuits by generation commands (or without command generation) to actuators.

Range of measuring power of gamma radiation exposure - doze 0.2-150 R/h
Response time – Powerful gamma radiation within 0.1sec / gamma radiation of contaminated terrain within 10sec / detection the the air vapors of poisonous chemical agents (outside the vehicle) within 40sec.

Filter-ventilator unit

The filter-ventilator unit serves to clean external air from poisonous substances, radioactive dust, biological aerosols, to supply cleaned air into the crew compartment and create overpressure in it, as well as to ventilate the crew compartment during firing and fire fighting system comes into action.

Air consumption – via absorber filter at least 100 cubic metres per hour / bypassing the absorber filter at least 390 cubic metres per hour.

Filter-ventilator unit functions in 2 modes:

1. Ventilation mode. In this case blower delivers the dust-free air to crew compartment passing by the absorber filter
2. Filtering and ventilation mode. In this mode the blower delivers the clean air to the crew compartment through the absorber filter

Yugoslavia was another country to licence build the Russian T-72. After the Yugoslavian Government secured the license the first prototypes were developed in 1982 for field testing and production began sometime in 1983. The first production vehicles were completed in 1984, hence the 84 in it‘s designation. The principle improvements over the T-72 was an improved composite armour, a locally manufactured fire control system and a 12-cylinder water-cooled V46-6 diesel engine generating 780hp.

Modernization of T-80 in Russia

After the disintegration of the USSR seemed that the development and modernization of the T-80 was over. One of the factories, with great influence, went to Ukraine, Leningrad closed shortly and the only one left, Omsk, entered into a long agony to go bankrupt in 2002. The design bureau was transferred to Uralvagonzavod, which makes the T-90.

T-80 in the Factory Repair 61 (Sergei Vladimirovich, Ïàðòèçàíñêàÿ Áàçà (Ðàáîòàåò íà Invision Power Board))


Nonetheless, the T-80 remained an important carriage Russian armed in the military. After 1991 Russia retained most, with Ukraine and Belarus inherited a small amount. Production was remarkable, more than 5,000 copies in all versions.
Russia operates three versions:

- T-80B: latest version to be mass produced. Ride a 1A33 fire control, armor Kontakt-1 ERA and a turbine GTD-1100T.
- T-80U: improved version with more armor and a GTD-1250 turbine for more power (since 1990). Your shot is higher (1st 45), but not mounted a thermal camera.
- T-80UD: diesel version of the T-80U with a motor 1.000HP 6TD-1.

In these versions, UD had no future. This car was produced in Ukraine and it was clear that Russia was not going to buy spare parts from a direct competitor. The number operated, although higher than Ukraine itself, was not very high. In fact operated with a single division, the 4th Armored Kantemirovskaya, famous for being deployed in Moscow during the 1991 coup.

The T-80U were not very numerous, as it began during perestroika, and tank production was drastically reduced. The T-80B is the most common model, and a tank is much easier to modernize the T-72 because they have a modern fire control, including ballistic computer, wind sensor and other elements.

In 2005 modernized versions officially entered service. They are called T-80uA and T-80EU-1 (not to be confused with the T-80UE 90. The T-80uA is a simple upgrade of U. The T-80UE-1 is somewhat more complex. When the T-80UD exhausted its useful life and are sent to stores / scrap, the tower were removed and mounted on a T-80BV. This way you can recycle a portion of the car. --translation




The modernization is focused on fire control and turbine. These models use a computer pass 1A45-1. The big news is the presence of a thermal imager pleated, French-Belarusian origin. This is a huge improvement because the vast majority of Russian tanks lacks these teams. At the same time, stabilization and precision is higher. Some recent photos show that they have received BMS control systems.

BMS System in T-80

Consider the results of tests performed by a prototype T-80 (Object 219), a T-64A and T-72:

- Average speed of 1.3 compared to T-64A/72.
- Time to complete a 1000kms up 1.5 times lower.
- After the march was a journey on a slope of 15 °, the Object 219 was two times faster.
- Number of maintenance 5 times lower.
- Habitability 2-3 times. The lower smoke and noise allowed to operate better with BMP, and the attack could be performed at twice the speed.
- Effective fire distance 1.3 times.
- Time to prepare the first shot 2.1 times lower.
- Time to prepare the engine at low temperature 8-10 times lower.
- Acceleration time 1.7 times less (does not say what speed).
- Accuracy 1.3-1.5 times greater.
- Time resupply 2.5-3 times lower. You can use helicopter fuel. The cost of the fuel is 1.5 times lower.
- The time to change the engine / transmission is the third.
- The length and complexity of maintenance is less than half.

More calculations performed by the Kirov plant, the defense ministry and the institute Minaviaproma:

- Probability of detection from the air 1.25-1.9 times lower.
- Time out of the contaminated area four times lower.
- Life of the motor 2 times greater.
- Using 1.5 times lower specific metals.

The T-72/64A consumed 4.5 liters / kms. The Object 219 6.2 l / km. GTD clear that the turbine is 1.251.4 times more potent than 5TDF or V-46. The protection was higher by using steel BTK-1:

Item 219:
Front tower: 500mm.
Chassis Front: 380mm.

T-72/64A:
Front tower: 410mm.
Chassis Front: 305mm.

In any case, we must not take everything at face value. These will likely be designed to see the virtues of the turbines, but have many drawbacks: they are much more expensive, more complex materials used and have a much lower life. In a circuit but may be lower when tested the Indians T-80U of the need for support vehicles was 3 times greater than in the T-90. The Russians argue that most of the time the extra power from the turbine is not used. In short, there are reasons for and against, but we must not forget that the Soviets ended up with a diesel version of the T-80, the UD.

The T-84 is the latest Ukrainian development of the T-80 series, designed by KMDB in Kharkiv. A main design objective was to make Ukraine's arms industry independent of Russia's, after resulting difficulties in fulfilling a contract to supply T-80UD tanks to Pakistan. An external difference from earlier models is the new Ukrainian welded turret, replacing the T-80's Russian-built cast turret (some T-80s shipped to Pakistan were fitted with the T-84 welded turret, but lack other T-84 improvements)

The “Object 292” test vehicle was produced by the Kirov Special Machinery Plant (Special Machinery, Limited), and the scientists at VNIITransmash. On the chassis of the T-80U they installed a new turret, a 152mm cannon, and some other parts. The turret and cannon were installed and in 1991, experiments began at Rzhev Poligon. Positive results were achieved.

Ballistically, the smoothbore 152mm was far superior to the 125mm, though the chamber dimensions were not that much bigger. A new combat compartment was also developed, which could be installed on T-80 tanks without modifications to the main chassis structure

t80u

t84

Contrary to the basic believe of the western and even Russian public T-72 is not a development of T-64A (the Soviet Main Battle Tank). T-72 vas development of Ural design bureau experimental tank that lost the competition to T-64 predecessor o. 430. That is why T-72 use the 22 rounds autoloader previously planned for modernized T-62. A completely different drivetrain and different turret.
The T-72 series itself was a “mobilization” tank of the soviet army. It was designed for mass production in war time in huge numbers.





T-72 predecessor o. 140 and 167



The most important threads of Soviet tank development before 1966

Basically the first automatic fire control and gun-lunched missile appeared on T-64B in 1976. Then it was installed on T-80. The automatic fire control was never installed on T-72 or it’s versions.
The same story with armor – while the T-64-s and T-80 was equipment with high cost composite armor the T-72 had the simplest possible sand rods and then reflecting plates which were much less valuable than advanced compositions of T-80U …
So the key idea is that T-72 was not the primary Soviet tank, it was exported worldwide to any nation possible. While no T-64 or T-80 was ever exported (After Soviet Union T-80U was exported to ROK, Cyprus and T-80UD to Pakistan)…



The most important threads of Soviet tank development after 1966

FIRE CONTROL

1-st T-72 and T-80/64 were equipped with different guns.
T-80/64 received newest guns much before T-72-variants.

T-64 fire control consists of (basic information)

Targeting complex 1A34
-laser sight 1G42 with block of shot permission 1G43 and tank ballistic computer 1V517.
The AUTOMATIC sensors of entering information are
Heel sensor 1B14
Wind sensor 1B11
relative bearing sensor
tank speed sensor

The following information is entered before combat manually is temperature of the air, type of ammunition batch, atmosphere pressure, charge temperature, air temperature, barrel wear.

In the automatic fire control the correction factor for target range, tank speed, target speed, wind are entered automatically. The gunner just puts the mark on the target and the gun is adjusted automatically to required position, the mark does not change it’s position.


What is T-72B fire control –

The automatic fire control was not installed on T-72.
Instead of ballistic computer the tank is equipped with ballistic corrector.
The correction factor for target range tank speed, target speed, wind are not entered automatically. The wind correction factor is measured “by eye” (until the last serial versions and T-72C).
The gunner puts the mark on the target measures the range with LRF, the mark moves lover depending on range … It requires more time then with automatic FCS.
Another diference of T-72B from T-64/80B is that T-72 can not fire guided missiles while moving…

2 – Block for entering corrections
3 – guidance block for 9K120
4 – control block
5 – converter for 9K120

10 – horizontal drive GN
12 – electric machine booster

T-80UD MBT

The T-80UD MBT armament includes a 125mm gun, 7.62mm coaxial machine gun and 12.7mm anti-aircraft machine gun. The tank crew is also equipped with sub-machine guns, hand grenades and a signal pistol.

The main armament comprises a 125mm KBA3 smoothbore gun fed by a carousel-type automatic loader and fitted with a thermal sleeve and fume extractor (bore evacuator). The main gun has a quick-replacement barrel which can be changed under field conditions without the need to remove the gun from the tank.

The number of rounds that T-80UD could carry is 45 two-piece rounds (projectile and charge), of which 28 rounds are placed in the automatic loader, with the remainder being stored at the driver's station and in the fighting compartment. Types of ammunition that can be fired by the gun include APFSDS (armour-piercing fin-stabilised discarding sabot), HEAT (high explosive anti-tank), HE-FRAG (high explosive fragmentation) rounds and laser beam-riding guided missiles.

The specific feature of the tank is that it is fitted with a guided missile system to enable the main gun to fire a laser guided missile with a maximum range of 5,000 m. The missile consists of two parts. The first part includes a pusher and an equipment compartment with control surface device. The second part includes a sustainer engine and a tandem warhead. Both parts are stowed in the automatic loader in the same way as conventional ammunition.The two parts get united into one body in the gun bore at the moment of firing.

The missile can be fired while both the tank and target are moving. The tandem warhead enables the missile to defeat targets fitted with explosive reactive armour with a high degree of efficiency.

Although the primary role of the missile is to engage battle tanks operating at ranges beyond the effective range of the 125mm tank gun firing conventional ammunition, it can also be fired against other battlefield targets such as hovering helicopters and pillboxes.

The coaxial machine gun can be aimed and fired from either gunner's or commander's station.

The anti-aircraft machine gun is mounted on the commander's cupola and is intended for use in the ground/air and ground/ground roles being aimed and fired while remaining in the vehicle under full armour protection from the commander's station. The machine gun can be elevated from -5° to +70° and traversed through +/-75° to the right and left of the vehicle longitudinal axis, or through +360° together with the tank turret. The machine gun is fitted with a vertical stabilisation system providing stabilisation in the vertical angle range of -3° to +20°.
Fire Control System

The T-80UD is fitted with an advanced fire control system, and either the gunner or commander can lay and fire the main armament at stationary and moving targets while the tank is stationary or moving with a high first round hit probability.

The fire control system comprises a gunner's 1G46 day sight, gunner's TO1-KO1E night vision system, commander's PNK-4S observation and sighting system, PZU-7 anti-aircraft sight, 1ETs29 anti-aircraft machine gun mount control system, 1V528-1 ballistic computer with input information sensors, 2E42 armament stabiliser and other devices.

The gunner's 1G46 day sight has a two-axis stabilised line of sight and incorporates a laser range-finder and a missile guidance capability.

In the standard version the gunner has a TO1-KO1E sighting system with TPN-4E image intensification sight, but as an option, the Buran-Catherine-E thermal imaging sight can be fitted.

The commander's PNK-4S observation and sighting system comprises a commander's TKN-4S combined day/night sight and a gun position sensor. The commander's TKN-4S combined sight is stabilised in the vertical plane and has three channels: a day unity vision channel, a day channel with magnification of x8 and a night channel with magnification of 5.4x. A simple switch enables the commander to change from the daylight channel to the night (image intensification) channel and back again.

The commander's anti-aircraft sight enables the commander to engage air targets by using the anti-aircraft machine gun from within the safety of the turret.

In order to calculate ballistic corrections, the 1V528-1 ballistic computer automatically takes into account all the inputs from the sensors including tank speed, angular target speed, gun trunnion axis cant, crosswind speed, target range, and course angle. Additionally, the following parameters are manually input: ambient air temperature, charge temperature, barrel wear ambient air pressure and so on. The computer also computes the time when the high-explosive fragmentation projectile with controlled detonation should be detonated over the target.

The fire control system has a so-called fire gating capability, i.e., after the gun firing button has been pushed, the gun will only fire when the misalignment between the line of sight and the gun bore axis is within pre-determined limits. The fire gate size is adjusted when calibrating the fire control system after installing it in the tank.

To enable a broad sector of terrain to be observed, the crew members are provided with unity magnification periscope vision blocks.

Protection

The armour protection of the T-80UD, which includes advanced multi-layer armour and explosive reactive armour package for the turret and chassis, provides to the T-80UD a high level of battlefield survivability.

The T-80UD can disguise itself on the battlefield by laying a smoke/aerosol screen. Mounted on either side of the turret is a bank of four electrically operated smoke grenade launchers.

The T-80UD can lay its own smoke screen by injecting diesel fuel in the engine exhaust (i.e. by using so-called engine smoke emitter).

To reduce the thermal signature of the tank on the battlefield, the T-80UD power pack compartment top deck is fitted with special heat insulation.


Explosive reactive armour installed on the glacis plate

Mobility

The T-80UD is powered by a model 6TD-1 6-cylinder diesel engine developing 1,000 hp.

The air inlet of the engine allows air to be ducted from the least dusty quarter and enables water obstacles to be crossed to a water depth of 1.8 m without preparation.

There are two parts to the air filtration system, the centrifugal pre-cleaners and the air cleaner casing. This enables the tank to be operated in hot and dusty conditions for up to 1,000 km without a change of filters and to carry out combat under radioactive conditions.

The suspension is of the torsion bar type with each side having six dual rubber-tyred road wheels with the idler at the front, drive sprocket at the rear and track support rollers.

The upper part of the suspension is covered by a skirt, the forward part of which is armoured (fitted with explosive reactive armour).

A rubber mat hangs at the front of the vehicle and this helps to keep down dust.


Fording without preparation and with preparation

Other Features

The T-80UD MBT standard equipment also includes an NBC system, provision for deep fording, fire detection/suppression system, radiation shielding and a dozer blade mounted under the front of the hull.

The NBC protection system protects the crew and inner equipment of the tank against the effects of nuclear explosions, radioactive dust, toxic agents and bacteriological materials.

The deep fording equipment enables the tank to cross water obstacles to a water depth of 5 m (1.8 m deep water obstacles can be crossed without preparation).

The fire detection/suppression system enables internal fires to be detected and suppressed in both crew compartment and power pack compartment.

The radiation shielding is designed in the form of liner fixed on both internal and external surfaces of the tank.

The dozer blade enables the tank to dig up a tank caponier within 15-40 minutes depending on the type of ground.

The T-80UD can be fitted with various types of mine-clearing system at the front of the hull including KMT-6 plough-type system and KMT-7 roller-type system. Two long-range fuel tanks and an unditching beam can be mounted at the rear of the hull.

The T-80UD MBT design and configuration can be changed to suit foreign customers' specific requirements.

publications


Two-view general arrangement drawing of the T-80UD MBT

Participation in Comparative Evaluation Trials

The T-80UD MBT was demonstrated and subjected to trials in Pakistan in 1993 and 1995 to meet this country's re requirement for a new MBT.

In 1996 Pakistan placed a contract with Ukraine for the supply of 320 T-80UDs. The first batch of 15 vehicles was delivered early in 1997, with final deliveries taking place in late 1999.

The vehicles of the final batches incorporated many features of the T-84, including an all-welded turret and other improvements.



T-80UD MBTs are in service with the Pakistani Army

Status

The T-80UD main battle tank is now in service with Ukraine, Russia and Pakistan.
