The T-64 is a Soviet second-generation main battle tank introduced in the early 1960s. It was a more advanced counterpart to the T-62: the T-64 served tank divisions, while the T-62 supported infantry in motorized rifle divisions. It introduced a number of advanced features including composite armor, a compact engine and transmission, and a smoothbore 125-mm gun equipped with an autoloader to allow the crew to be reduced to three so the tank could be smaller and lighter. In spite of being armed and armored like a heavy tank, the T-64 weighed only 38 tonnes (42 short ton s; 37 long ton s).

Contents

These features made the T-64 expensive to build, significantly higher than previous generations of Soviet tanks. This was especially true of the power pack, which was time-consuming to build and cost twice as much as more conventional designs. Several proposals were made to improve the T-64 with new engines, but chief designer Alexander Morozov's political power in Moscow kept the design in production in spite of any concerns about price. This led to the T-72 being designed as an emergency design, only to be produced in the case of a war, but its 40% lower price led to it entering production in spite of Morozov's objections.

At present the T-64 is in use in very few nations or regions, but is currently undergoing significant factory overhauls and modernization in Ukraine. The newest, vastly upgraded and improved model of this 50-year-old design, the T-64BM Bulat, has increased in weight to 45 tonnes and is seeing active service in the field.

Overview

The T-64 was conceived at the Kharkiv Morozov Machine Building Design Bureau in Ukraine (Ukrainian SSR), as the next-generation main battle tank by Alexander A. Morozov, the designer of the T-54 (which, in the meantime, would be incrementally improved by Leonid N. Kartsev's Nizhny Tagil bureau, by the models T-54A, T-54B, T-55, and T-55A).

A revolutionary feature of the T-64 is the incorporation of an automatic loader for its 125-mm gun, allowing one crew member's position to be omitted and helping to keep the size and weight of the tank down. Tank troopers would joke that the designers had finally caught up with their unofficial hymn, Three Tankers—the song had been written to commemorate the crewmen fighting in the Battle of Khalkhin Gol, in 3-man BT-5 tanks in 1939. [3]

The T-64 also pioneered other Soviet tank technology: the T-64A model of 1967 introduced the 125-mm smooth-bore gun, and the T-64B of 1976 would be able to fire an anti-tank guided missile through its gun barrel.

The T-64 design was used as basis by LKZ for the gas turbine-powered T-80 main battle tank. The T-64A turret was adopted for early T-80 tank models, with its main gun and automatic loading mechanism, and upgraded armour.

The T-64 would only be used by the Soviet Army and never exported, unlike the T-54/55. The tank equipped elite and regular formations in Eastern Europe and elsewhere, the T-64A model being first deployed with East Germany's Group of Soviet Forces in Germany (GSFG) in 1976, and some time later in Hungary's Southern Group of Forces (SFG). By 1981, the improved T-64B began to be deployed in East Germany and later in Hungary. While it was believed that the T-64 was reserved for elite units, it was also used by much lower level "non-ready formations", for example, the Odessa Military District's 14th Army.

With the break-up of the Soviet Union in 1991, T-64 tanks remained in the arsenals of Russia, Ukraine, Belarus and Uzbekistan. Mid 2014, slightly fewer than 2,000 of the former Soviet inventory of T-64 tanks are in service with the military of Ukraine and about 4,000 are out-of-service and awaiting destruction in Russia.

Development history

Studies for the design of a new battle tank started as early as 1951. The KB-60M team was formed at the Kharkiv design bureau of the Kharkiv transport machine-building factory No. 75 named for Malyshev (Russian : конструкторское бюро Харьковского завода транспортного машиностроения №75 им. Малышева) by engineers coming back from Nizhniy Tagil, with Morozov at its head.

A project named obyekt 430 gave birth to three prototypes which were tested in Kubinka in 1958. [5] Those vehicles showed characteristics that were going to radically change the design of battle tanks on this side of the Iron Curtain. For the first time, an extremely compact opposed-piston engine was used: the 4TD, designed by the plant's engine design team. The transmission system comprised two lateral gears on each side of the engine. Those two innovations yielded a very short engine compartment with the opening located beneath the turret. The engine compartment volume was almost half that of the T-54. An improved cooling system and a new lightweight suspension was fitted, featuring hollow metallic wheels of a small diameter and caterpillar tracks with rubber joints.

The tank would be armed with the D-54TS and frontal armour of 120mm. As it did not present a clear superiority in terms of combat characteristics when compared to the T-55, which was entering active service, Morozov decided that production was not yet ready given the project's drawbacks. However, studies conducted on the obyekt 430U, featuring a 122mm gun and 160mm of armour, demonstrated that the tank had the potential to fit the firepower and armour of a heavy tank on to a medium tank chassis. A new project was consequently started, obyekt 432.

Object 432

The gun fitted on this new tank was a powerful 115mm D-68 (2A21). This was a potentially risky decision to replace the human loader by an electro-hydraulic automatic system, since the technology was new to Russian designers. The crew was reduced to three, which allowed a considerable reduction in internal volume and external visible silhouette, and consequently in weight, from 36 tonnes (obyekt 430) to 30.5 tonnes. The height dropped by 76mm.

However, the arrival of the British 105 mm L7 gun and the US M68 variant of it, fitted to the Centurion and M60 tanks, forced the team to undertake another audacious première, with the adoption of composite armour. The recently created process was called "K combination" by Western armies: this protection consisted of an aluminium alloy[ citation needed ] layer between two high strength steel layers. As a consequence, the weight of the prototype rose eventually to 34 tonnes. But, as the engine was now a 700hp (515kW) 5TDF (also locally designed), its mobility remained excellent, far superior to that the T-62. The obyekt 432 was ready in September 1962 and production started in October 1963 in the Kharkiv plant. On 30 December 1966, it entered service as the T-64.

Even as the first T-64s were rolling off the assembly lines, the design team was working on a new version, named object 434, which would allow it to maintain firepower superiority. The brand new and very powerful 125mm D-81T gun, from the Perm weapons factory, was fitted to the tank. This gun was merely a scaled-up version of the 115mm smoothbore cannon from the T-62. The larger size of the 125mm ammunition meant that less could be carried inside the T-64, and with a fourth crewman loader taking up space as well, the tank would only have a 25-round capacity. This was unacceptably low for the Soviet designers, but strict dimensional parameters forbade them from enlarging the tank to increase interior space. The solution was to replace the human loader with a mechanical autoloader, cutting the crew to three and marking the first use of autoloaders in a Soviet MBT. [6] The 6ETs10 autoloader has 28 rounds and can fire 8 shots per minute; the stabiliser, a 2E23, was coupled to the new TPD-2-1 (1G15-1) sight. Night driving was also adapted with the new TPN-1-43A periscope, which would benefit from the illumination of a powerful infrared L2G projector, fitted on the left side of the gun. The shielding was improved, with fibreglass replacing the aluminium alloy in the armour, and small spring-mounted plates fitted along the mudguards (known as the Gill skirt), to cover the top of the suspension and the side tanks. They were, however, extremely fragile and were often removed. Some small storage spaces were created along the turret, with a compartment on the right and three boxes on the front left. Snorkels were mounted on the rear of the turret. A NBC protection system was fitted and the hatches were widened.

Prototypes were tested in 1966 and 1967 and, as production began after the six hundredth T-64, it entered service in the Soviet Army under the designation T-64A. Chief engineer Morozov was awarded the Lenin Prize for this model's success.

Designed for elite troops, the T-64A was constantly updated as available equipment was improved. After only three years in service, a first modernisation occurred, regarding:

A derived version appeared at the same time, designed for the commanding officer and named T-64AK. It comprised a R-130M radio with a 10m telescopic antenna, which could be used only in a static position as it required shrouds, an artillery aiming circle PAB-2AM and TNA-3 navigation station; all of these could be powered by an auxiliary gasoline-fired generator.

In 1976, the weapons system was improved by mounting a D-81TM (2A46-1), stabilised by a 2E28M2, supplied by an automatic 6ETs10M. The night sight was replaced by a TNPA-65 and the engine could accept different fuels, including diesel fuel, kerosene or gasoline. The production, first carried on the B variant, stopped in 1980.

The majority of T-64As were further modernised after 1981, by mounting a six smoke grenade-launcher 81mm 902A on each side of the gun, and by replacing the gill plates by a rubber skirt for a longer life. Some of them seem to have been fitted with reactive bricks (as the T-64AV) after 1985, or even with laser TPD-K1 telemeters instead of the optical TPD-2-49 optical coincidence rangefinder (1981). Almost all T-64s were modernised into T-64R, between 1977 and 1981, by reorganising external storage and snorkels, similar to the T-64A.

T-64B

The design team was carrying on its work on new versions. Problems with the setup of the 5TDF engine occurred as the local production capacity was proven to be insufficient against a production done in three factories (Malyshev in Kharkiv, Kirov in Leningrad and Uralvagonzavod).

From 1961, an alternative to the obyekt 432 was studied, with 12 V-cylinder V-45 engine: the obyekt 436. Three prototypes were tested in 1966 in the Chelyabinsk factory. The order to develop a model derived from the 434 with the same engine gave the obyekt 438, later renamed as obyekt 439. Four tanks of this type were built and tested in 1969, which showed the same mobility as the production version, but mass production was not started. They served however as a basis for the design of the T-72 engine compartment.

At the beginning of the 1970s, the design team was trying to improve the tank further. The T-64A-2M study in 1973, with its more powerful engine and its reinforced turret, served as a basis for two projects:

For the latter, the order was given to start its production under the name T-64B, as well as a derived version (which shared 95% of its components), the obyekt 437, without the missile guidance system for cost reasons. The latter was almost twice as much produced under the designation T-64B1. On 3 September 1976, the T-64B and the T-64B1 were declared good for the service, featuring the improved D-81Tm gun (2A46-2) with a 2E26M stabiliser, a 6ETs40 loader and a 1A33 fire control, including:

Its ford capacity reaches 1.8 m without equipment. The T-64B had the ability to fire the new 9M112 "Kobra" radio-guided missile (NATO code "AT-8 Songster"). The vehicle then carries 8 missiles and 28 shells. The missile control system is mounted in front of the tank leader small turret and has many changes. The T-64B1 carries only 37 shells and has 2,000 7.62mm rounds, against 1,250 for the T-64B.

They were modernised in 1981 by the replacement of the gun by a 2A46M1, the stabiliser by a 2E42, and the mounting of a 902A "Tucha-1" smoke grenade launcher in two groups of four, on each side of the gun. Two command versions are realised, very similar to the T-64AK: the T-64BK and the T-64B1K.

The decision, in October 1979, to start production of the 6TD engine, and its great similarity with the 5TDF engine, allowed after some study to fit it in versions B and B1, but also A and AK, yielding the new models T-64AM, T-64AKM, T-64BM and T-64BAM, entering service in 1983.

The production ended in 1987 for all versions. The total production has reached almost 13,000.

Modernisations in Ukraine

After the dissolution of the USSR, Ukraine carried on the development of T-64 modernization, as the original and main factory was in this country. Two different upgrade packages were developed in 1999 [7]

The two variants are also protected by Kontakt-5 modular reactive armour, able to resist to kinetic energy projectiles, as opposed to the first models which were efficient only against HEAT shaped-charge ammunition. Those two variants could also be re-motorised with the 6TDF 1,000hp (735kW) engine.[ citation needed ]

In 2010, the Kharkiv Malyshev Factory upgraded ten T-64B tanks (originally produced in Kharkiv in 1980) to T-64BM Bulat standard, and a further nineteen were delivered in 2011. These twenty-nine tanks are being upgraded under a ₴200 million ($25.1M) contract signed in April 2009. As of October 2011, the Ukrainian Army has 76 T-64BM Bulat in service. According to Malyshev Factory chief engineer Konstantin Isyak, the T-64BM Bulat is armoured to the level of modern tanks. It has Nizh (Knife) reactive armour, and Varta active protection system. The Bulat weighs 45 tonnes (44 long tons), and with its 850 hp (630 kW) 5TDFM multi-fuel diesel engine can travel at 70 km/h (43 mph), with a range of 385 km (239 mi). It retains the 125mm smoothbore gun with an autoloader for 28 rounds, some of which can be guided missiles. It has a 12.7mm AA machinegun, and a 7.62mm coaxial machinegun. [8] [9] A 2019 refurbishing program upgraded the fire-control system to model 1A43U and uprated the engine. [10]

In 2019, UkrOboronProm reported that the Kharkiv Armored Plant (KhBTZ) had delivered over 100 updated tanks to the Ukrainian Armed Forces. [11] The upgraded tanks included new thermal imaging for all crew, remove Luna infrared searchlight, include TPN-1-TPV Ukrainian night sight in place of TPN1-49-23, Nizh reactive armour modules designed for bolt-on replacement on T-64BV turrets, SN-4215 networked satellite navigation unit, and Lybid K-2RB digital radio (under licence from Motorola) providing secure communications with a 70 km range. [12] In August 2019, UkrOboronProm announced the Lviv Armored Plant (LBTZ) had also started modernizing T-64s to the 2017 standard [13]

Production history

Different sources differ on the initial production date of the tank that is set between 1963 and 1967. However it is normally agreed that the T-64 formally entered service with the army in 1967 and was publicly revealed in 1970. [14] [15] The T-64 was KMDB's high-technology offering, intended to replace the IS-3 and T-10 heavy tanks in independent tank battalions. Meanwhile, the T-72 was intended to supersede the T-55 and T-62 in equipping the bulk of the Soviet tank and mechanized forces, as well as for export partners and east-block satellite states.

It introduced a new autoloader, which is still used on all T-64s currently in service, as well as all variants of the T-80 except the Ukrainian T-84-120. The T-64 prototypes had the same 115mm smoothbore gun as the T-62, the ones put in full-scale production had the 125mm gun.

While the T-64 was the superior tank, it was more expensive and physically complex, and was produced in smaller numbers. The T-72 is mechanically simpler and easier to service in the field, while it is not as well protected, and its manufacturing process is correspondingly simpler. In light of Soviet doctrine, the superior T-64s were kept ready and reserved for the most important mission: a potential outbreak of a war in Europe.

In Soviet times, T-64 was mostly in service with units stationed in East Germany opposing the Chieftain-equipped units of the BAOR. No T-64s were exported. Many T-64s ended up in Russian and Ukrainian service after the breakup of the Soviet Union.

BAT-2 combat engineering vehicle
  • BMPV-64 – Heavy infantry fighting vehicle, based on the chassis of the T-64 but with a completely redesigned hull with a single entry hatch in the rear. Armament consists of a remote-controlled 30mm autocannon and 7.62mm machine gun. Combat weight is 34.5 tons. The first prototype was ready in 2005. [23] [24]
  • BTRV-64 – Similar APC version. [24]
  • UMBP-64 – Modified version that will serve as the basis for several (planned) specialized vehicles, including a fire support vehicle, an ambulance and an air-defence vehicle.
  • BMPT-K-64 – This variant is not tracked but has a new suspension with 4 axles, similar to the Soviet BTR series. The vehicle is powered by a 5TDF-A/700 engine and has a combat weight of 17.7 tons. It is fitted with a RCWS and can transport 3+8 men. Prototype only.

  • BAT-2 – Fast combat engineering vehicle with the engine, lower hull and "small roadwheels" suspension of the T-64. [25] The 40-ton tractor sports a very large, all axis adjustable V-shaped hydraulic dozer blade at the front, a single soil ripper spike at the rear and a 2-ton crane on the top. The crew compartment holds 8 persons (driver, commander, radio operators plus a five-man sapper squad for dismounted tasks). The highly capable BAT-2 was designed to replace the old T-54/AT-T based BAT-M, but Warsaw Pact allies received only small numbers due to its high price and the old and new vehicles served alongside during the late Cold War.
  • UMR-64 – Ukrainian development using surplus T-64s to create a Heavy APC/IFV design, which in turn is intended as the basis of a new family of combat and support vehicles. The basic conversion includes moving the engine compartment forward, and at the same time removing the turret and normal crew compartment. This allows the installation of any one of 15 different 'functional modules', weighing up to 22 tons. One resulting option is the Heavy IFV, designated BMP-64E, which combines accommodation for up to 10 troops (not including the driver) with a remote weapons system. The Heavy APC version is designated the BTR-64E, and can not only carry more troops (at the cost of the RWS) but comes with large armoured double hatches at the rear for rapid loading and disembarkation. Other options include a universal supplies carrier (UMBP-64), a 'highly secure command and staff car with a weight up to 41 tons', and a 120 mm mortar carrier. The Kharkiv Armor Repair Plant (Zavod 311) is behind the project. [26] Current status of the program is unclear as of early 2014.

Service history

Cold War

According to David Isby, the T-64 entered service in 1967 with the 41st Guards Tank Division in the Kiev Military District, [27] the suggestion being that this was prudent due to the proximity of the division to the factory, and significant teething problems during induction into service that required constant presence of factory support personnel with the division during acceptance and initial crew and service personnel training on the new type. It appears that the tank remained secret to the West for some years between its entry into production in the first half of 1960s and the official acceptance in the Soviet Army in 1967.

The T-64A began deployment to the Soviet Union's western military districts during the 1970s, and was gradually deployed to first line units in the Group of Soviet Forces in Germany in East Germany and Soviet troops in neighboring Warsaw Pact states. The first GSFG unit to receive the T-64A was the 14th Guards Motor Rifle Division at Jüterbog, which became the 32nd Guards Tank Division in 1982. When NATO detected the new tank after it was first deployed to East Germany, it was initially misidentified as the T-72. The T-64 mainly served with Soviet tank units in northern East Germany that were part of the 2nd Guards Tank Army, the 3rd Army, and the 20th Guards Army, although it began to be phased out and replaced by the newer T-80BV/T80U before Soviet troops were withdrawn from Germany in the late 1980s and early 1990s. However, when the Soviet troops withdrew from Germany, two divisions and the 6th Separate Guards Motor Rifle Brigade still operated the T-64. [28]

In September 1990, the Soviet Union had 3,982 T-64s in service west of the Urals, with 2,091 of these in Ukraine. 1,386 of these were T-64As, 220 T-64AKs, 1,192 T-64Bs, 159 T-64BVs, 420 T-64B1s, 27 T-64B1K/BV1K, and 578 T-64Rs. [28] During the Soviet period, the T-64 was never exported. [29]

It is normally reported that the T-64 was not used in the Soviet–Afghan War since the 40th Soviet Army that was deployed there used T-54/55 and T-62 tanks, possibly due to the limited use of tanks in mountain warfare. A small number of T-64 tanks were tested in Afghanistan [30] during January 1980, but were quickly withdrawn without seeing combat because their engines did not perform well in the high altitude necessary for Afghan operations. [29]

After the dissolution of the Soviet Union in 1991, the new Russian Ground Forces decided to standardize the tank fleet with the T-72 and the T-80, and the T-64s were gradually put in reserve or scrapped. [28]

In June 1992, 18 Russian-manned T-64BV tanks from the Odessa Military District's 59th Guards Motor Rifle Division were taken over by the Transnistrian Army, fighting in the Transnistria War. Two T-64s were disabled during by Moldovan Ground Forces troops near Bender during Transnistrian counterattacks, [31] one of which was knocked out by an MT-12 100mm anti-tank gun. These actions were the first combat use of the tank. [29]

While Russian T-80 tanks participated in the First Chechen War, any use of T-64 in Chechnya is not clearly documented, but it is possible in limited numbers.

The T-64 was finally used in large scale combat in mid 2014 during the War in Donbass, with the Ukrainian Army deploying T-64 tanks as the main battle tank in the offensive against pro-Russian separatists. Also, towards the end of August 2014, over 20 T-64 tanks were documented as being operated by Military forces of Novorossiya. [32] Ukrainian and NATO officials claimed that these T-64s were supplied to the separatists by Russia. [33] By the end of August 2014, over 70 T-64 tanks of various configurations, including at least three T-64 BM Bulat tanks, were documented as destroyed [34] in the war in Donbass.

The subsidiary of the State Company Ukrspecexport, the State Company Ukroboronservice, concluded the foreign economic contract for major overhaul and supply of 50 main battle tanks T64BV-1. The works will be performed by the State Enterprise Kharkiv plant of armored tanks. [35] [36]

The Armed Forces of the Democratic Republic of the Congo received 25 T-64BV from late 2016. They were seen in mid-2017 patrolling in Kasaï during the Kamwina Nsapu rebellion. [37]

Capabilities and limitations

A rather unconventional design, the T-64 had several features which set it apart not only from previous tanks, but from the visually similar T-72, many related to its higher mechanical complexity:

Firepower
  • The T-64's hydraulic "Basket" autoloader places the projectiles horizontally at the bottom of the turret facing towards the center, and the propellant charges vertically along the outer rim of the turret race, front-down. By contrast, the T-72's "Cazette" mechanism places the propellant charge on top of the corresponding projectile, also horizontally.
    • Being hydraulic, the Basket-type created a risk of hydraulic fluid fire if damaged in combat. The Cazette, by contrast, is electric.
    • Basket-type folds the projectile cradle upwards off the floor and vertically against the projectile cradle to which it is hinged, moving both pieces into the upper turret. Approaching the gun, the projectile cradle is moved forwards, unfolding both cradles and ammunition pieces to a straight line, ready for insertion. The Cazette's cradles are fixed, stacked propellant on top of projectile, and the two-cradle assembly must raise the propellant part above the gun to load the projectile first, then drawing back the mechanical pusher, lowering the propellant part, and inserting it with a second use of the pusher. This increases the time of loading of the T-72 by approximately one second. Total loading time is thus ~6-13s for T-64/80 against ~7-15 of T-72.
    • Because of greater diameter, Basket-type holds projectile and propellant parts for 6 additional shots over the Cazette of T-72 (28 vs 22).
    • Because of greater diameter of projectile cradle ring of the Basket-type, T-64 and later T-80 have a higher limit to the maximum length of APFSDS projectiles, providing superior anti-armour performance relative to shorter projectiles used by T-72.
    • The automatic loader of T-64 is more reliable, and less sensitive to jolting when running off-road. It also has a "sequence" fire mode that feeds the gun with shells of the same type in less than five seconds. In the modern versions it is also able to turn backwards to keep a good speed at the end of the loading sequence
    • Early versions of the basket autoloader lacked safety features and were dangerous to the tank crews (especially the gunner, who sits nearby): Limbs could be easily caught in the machinery rotating around the crew, leading to injuries and deaths. A sleeve unknowingly snagged on one of the autoloader's moving parts could also drag a crewman into the apparatus upon firing. [6]
  • The tank commander's cupola provides good vision, the antiaircraft machine gun can be operated from inside the turret; the commander can also control the main gun sight if necessary
  • The turret was poorly configured to allow the crew to manually load the gun should the autoloader break. In such situations, rate of fire usually slowed to an abysmal one round per minute as the gunner fumbles with the awkward task of working around the broken machine to load the gun. [6]
  • Although two-piece ammunition allows for fast reloading of the gun in combat, replenishing the autoloader is quite slow.
Movement
  • Because of a lower weight than T-72 (by ~3 tonnes), T-64 has slightly superior strategic and operational mobility (less wear and tear on tank transportation equipment, and lower fuel consumption per distance traveled.
  • Driving seems much less exhausting for the crew, thanks to assisted controls and a more flexible suspension. [38]
  • The suspension system featured an entirely new and advanced design, and suffered various failures of unusually high frequency. Due to these problems, teams of civilian mechanics from the T-64 factories were "semi-permanent residents" of Soviet tank units early in the T64's initial adoption phase. [39]
  • The 5TDF opposed-piston engine, while powerful and compact, was very finicky and prone to malfunctions and fires. Russian expert Viktor Murakhovsky, then a battalion commander in Group of Soviet Forces in Germany reflected that in his unit the rate of the engines requiring a major overhaul was close to one per tank in a year. He also noted the difficulty of starting this engine, especially in the damp German winters, and that starting aids used by soldiers, like the high-pressure air and/or oil injection, often caused engine fires.
Protection
  • Basket-type autoloader stores, as stated previously, propellant charges vertically, the rear ends almost the same height as the roof of the hull. Combined with greater diameter of the complete autoloader assembly, the overall greater size of this type compared to the cazette significantly increases chance of ammunition being ignited by direct hit of any weapon penetrating into the crew compartment. The problem is largely irrelevant if a full ammunition load outside autoloader is carried, but T-72 carrying only autoloader ammunition is far more survivable than a T-64 in a similar situation thanks to the compact dimensions of Cazette-type ammunition storage.
  • Small and lightly constructed roadwheels of T-64 have been found to be less resistant to antitank mines than the larger roadwheels of T-72 and previous soviet medium tanks.
  • Because of the small-diameter roadwheels and vertical placement of propellant charges in the autoloader, charges are dangerously exposed against hits penetrating the 85mm hull side armour, and are located at such height that they are too high to be protected by the roadwheels, yet too low to be fully protected by the sideskirt armour panels.
  • While many previous tanks used 4 or 5-man crews, T-64 and T-72 have crews of three men. This allows the fourth man to remain in relative safety away from combat and perform other duties until the tank returns for maintenance and resupply. Potentially, he and other would-be loaders can be reassigned to vehicle maintenance and resupply duty to assist the crews of other returning tanks, improving the quality of maintenace as the crew inside the tanks will likely be exhausted after several hours of operation.
  • Because of smaller physical characteristics thanks to the 3-men +autoloader design, T-64 and T-72 have a lower theoretical logistical footprint than tanks of equal number using a human loader. This decreases the chance of the logistics chain being detected and attacked, and decreases potential losses.
  • Counter to the benefit of leaving the fourth crew man in favour of using an automatic loader, this also creates difficulties in immediately replacing an injured crewman while in combat. In comparison with 4-man tanks, there exists a possibility of an injured crewman being dragged from his seat and into the loader's space for immediate treatment of injury while the tank retreats. In more cramped 3-man designs such empty space is not immediately available and moving between the turret and hull may be more difficult in the first place. There is also an argument that a fourth crewman can replace any other of the three in case of injury, however, this possibility can also exist in 3-man designs if redundancy of weapon controls allows for temporary 1-man operation of turret.
  • Because of weight limitations of the powertrain, T-64 had lower overall capacity for improvements which add weight to the tank. Because improvements of armour tend to have a greater cost in weight than, say, replacement of gun optics and turret/gun laying drives with more precise versions, this means T-64 suffers greater limitations in terms of protection improvement than the heavier T-72, which was designed with a more durable powertrain from the start.
Concerns of 3-man & 4-man maintenance.
  • While having smaller tank crews (three vs. the usual four) is advantageous since more tanks can theoretically be fielded using the same number of soldiers, there are also serious downsides. Tanks require frequent maintenance and refueling, and much of this is physically demanding work that several people must work together to accomplish. Most of the time, these duties are also performed at the end of a long day of operations, when everyone in the tank is exhausted. Having one less crewman for these tasks increases the strain on the remaining three men and increases the frequency of botched or skipped maintenance. This problem worsens if the tank's commander is also an officer who must often perform other duties such as higher-level meetings, leaving only two men to attend to the tank. [40] All of this means that tanks with three-man crews are more likely to suffer from performance-degrading human exhaustion, and mechanical failures that take longer to fix and that keep the tank from reaching the battlefield. These problems are exacerbated during prolonged time periods of operations.

T-72 Soviet second-generation main battle tank

The T-72 is a family of Soviet main battle tanks that first entered production in 1971. About 20,000 T-72 tanks were built, The T-72A version introduced in 1979 is considered a second-generation main battle tank. It was widely exported and saw service in 40 countries and in numerous conflicts. The T-72B3 version introduced in 2010 is considered a third-generation main battle tank.

T-54/T-55 1946 main battle tank family of Soviet origin

The T-54 and T-55 tanks are a series of Soviet main battle tanks introduced in the years following the Second World War. The first T-54 prototype was completed at Nizhny Tagil by the end of 1945. Initial production ramp up settled for 1947 at Nizhny Tagil, and 1948 for Kharkiv were halted and curtailed as many problems were uncovered; the T-34-85 still accounted for 88 percent of production through the 1950s. The T-54 eventually became the main tank for armoured units of the Soviet Army, armies of the Warsaw Pact countries, and many others. T-54s and T-55s have been involved in many of the world's armed conflicts since the later part of the 20th century.

T-62 1961 main battle tank family of Soviet origin

The T-62 is a Soviet main battle tank that was first introduced in 1961. As a further development of the T-55 series, the T-62 retained many similar design elements of its predecessor including low profile and thick turret armor. In contrast with previous tanks, which were armed with rifled tank guns, the T-62 was the first tank armed with a smoothbore tank gun that could fire APFSDS rounds at higher velocities. While the T-62 became the standard tank in the Soviet arsenal, it did not fully replace the T-55 in export markets due to its higher manufacturing costs and maintenance requirements compared to its predecessor. Although the T-62 was replaced in Russia and the successor states of the Soviet Union, it is still used in some countries and its design features became standardized in subsequent Soviet and Russian mass-produced tanks.

T-80 main battle tank

The T-80 is a third-generation main battle tank (MBT) designed and manufactured in the Soviet Union. When it entered service in 1976, it was the first MBT in the world to feature a powerful multifuel turbine engine as its main propulsion engine. The T-80U was last produced in a factory in Omsk, Russia, while the T-80UD and further-developed T-84 continue to be produced in Ukraine. The T-80 and its variants are in service in Belarus, Cyprus, Egypt, Kazakhstan, Pakistan, Russia, South Korea, and Ukraine. The chief designer of the T-80 was the Soviet engineer Nikolay Popov.

BMP-3 Soviet designed amphibious infantry fighting vehicle

The BMP-3 is a Soviet and Russian infantry fighting vehicle, successor to the BMP-1 and BMP-2. The abbreviation BMP stands for boevaya mashina pehoty.

T-84 main battle tank

The T-84 is a Ukrainian main battle tank (MBT), a development of the Soviet T-80 main battle tank introduced in 1976. The T-84 was first built in 1994 and entered service in the Ukrainian Armed Forces in 1999. The T-84 is based on the diesel-engined T-80 version, the T-80UD. Its high-performance opposed-piston engine makes it one of the fastest MBTs in the world, with a power-to-weight ratio of about 26 horsepower per tonne. The T-84 Oplot is an advanced version incorporating an armoured ammunition compartment in a new turret bustle; ten of these entered Ukrainian service in 2001. The T-84-120 Yatagan is a prototype model intended for export, mounting a 120 mm gun capable of firing standard NATO ammunition and guided missiles.

The PT-76 is a Soviet amphibious light tank that was introduced in the early 1950s and soon became the standard reconnaissance tank of the Soviet Army and the other Warsaw Pact armed forces. It was widely exported to other friendly states, like India, Iraq, Syria, North Korea and North Vietnam. Overall, some 25 countries used the PT-76.

BMD-1 infantry fighting vehicle

The BMD-1 is a Soviet airborne amphibious tracked infantry fighting vehicle, which was introduced in 1969 and first seen by the West in 1970. BMD stands for Boyevaya Mashina Desanta. It can be dropped by parachute and although it resembles the BMP-1 it is in fact much smaller. The BMD-1 was used as an IFV by the Soviet Army's airborne divisions. An improved variant of the BMD-1 was developed, the BMD-2. The BMD-1 also provided a basis for the BTR-D airborne multi-purpose tracked APC.

BMD-2 soviet Infantry Fighting Vehicle

The BMD-2 is a Soviet airborne infantry fighting vehicle, introduced in 1985. It is a variant of BMD-1 with a new turret and some changes done to the hull. BMD stands for Boyevaya Mashina Desanta. It was developed as a replacement of BMD-1 but it failed to replace it completely because of the downfall of Soviet economy in 1980s. NATO gave it the designation BMD M1981/1.

Tank gun class of artillery mounted on a tank as its main armament

A tank gun is the main armament of a tank. Modern tank guns are large-caliber high-velocity guns, capable of firing kinetic energy penetrators, high explosive anti-tank rounds, and in some cases guided missiles. Anti-aircraft guns can also be mounted to tanks.

In armored warfare, an autoloader or auto-loader is a mechanical aid or replacement for the personnel that load ordnance into crew-served weapons, such as tanks and artillery. The term is generally only applied to larger weapons that would otherwise have a dedicated person or persons loading them.

BMP development infantry fighting vehicle series

The BMP series of infantry fighting vehicles were among the first production line Infantry Fighting Vehicles. Included in the series are the mainline BMPs, the airborne variant BMDs, and licensed modified and reverse engineered versions. BMP stands for Boyevaya Mashina Pekhoty, meaning "infantry fighting vehicle"). They were initially developed in the 1960s in the Soviet Union.

The T-54 and T-55 combines a high-velocity gun with a highly mobile chassis, low silhouette, and exceptional long-range endurance. The T-54/55 tanks have been produced in greater quantity than any other tank in the world. Seven main production models have been widely used throughout the Warsaw Pact and in many other countries. The T-54/55 series has been manufactured in Czechoslovakia and Poland as well as in China where it is known as Type 59. More than a dozen countries have produced upgraded T-55 variants with similar capabilities in protection and lethality. The tank featured many innovations, many of these being in the fire controls of the T-54 and the T-55.

Tanks of the post–Cold War era major division of geological time

The post–Cold War era is the period in world history from the collapse of the Soviet Union on December 25, 1991 to the present. During the Cold War (1947–1991), the Soviet domination of the Warsaw Pact led to effective standardization on a few tank designs. In comparison, France, Germany, the United States, and the United Kingdom had previously developed their own tank designs, but now tried to standardize their designs, while the smaller nations of NATO purchased or adapted these designs.
