T-64

Soviet Union Soviet Union (1963)
Main battle tank ~ 12,000 built

The world's most technologically advanced MBT

The T-54/55 were, in 1960, relatively rugged and proven designs, derived from WW2 ideas and concepts. But, with Western countries advancing quickly towards a new generation of battle tanks, the USSR needed to make a bold step forward from its previous designs to keep the edge. By the fall of 1959, the T-62 project was advancing fast at Nizhny Tagil, designed by a young team, and looked revolutionary with its new smoothbore gun.

Alexander Morozov, the chief engineer and father of the T-54/55 family, then headed the Kharkiv factory plant design bureau (KMDB) in Ukraine. He also sought to design the next-generation main battle tank, and also thought a new gun was the necessary upgrade around which the whole new design should revolve. This gun, the 2A46, would be derived from the new generation of Soviet AT smoothbore tracted guns, the 2A45 125 mm (4.92 in). And it would be coupled with other innovations, like an auto-loader, reducing the crew to just three, an upgraded 5DTF 5-cyl. diesel engine, and a completely new and reworked suspensions system, along with upgraded equipment. But its development took time, and the T-62 was unveiled and mass-produced earlier. The T-64 was eventually built from mid-1960 to late 1980s and upgraded, standing apart as an elite MBT, and precursor of the second generation MBT T-72, which took a great deal from it. Its real successor came in the 1990, after the fall of USSR, with the equally advanced T-90.

Development history

Alexander Morozov commenced studies for a new tank when the T-54 was just entering full production, back in 1951. The T-54/55 family, in the meantime, greatly evolved, and the production was eventually resumed in 1987, after nearly 33 years of incremental modernization.

The Object 430

At the Kharkiv transport machine-building factory No. 75, the KB-60M team was formed at the factory design bureau, with engineers from Nizhniy Tagil and headed by A.A. Morozov. They designed a new engine, which was a real departure from previous diesel of conventional design, with the compact opposed-piston 4TD mounting, coupled with two lateral gears on each side, that allowed even more compactness. by these means they achieved the unthinkable, providing more power with a far smaller and lower engine (the engine compartment was half the size of the T-55). Even the exhaust was revamped, with a new extracting system. To get the new hull moving, modeled around this engine, they also designed a new lightweight suspension made of small hollow aluminum roadwheels and tracks with rubber joints. But the gun was the same D-54TS of the T-55, and the armored glacis kept at 120 mm (4.72 in). Two prototypes were eventually built and fully tested at Kubinka in 1958. But Morozov estimated that the numerous issues caused by the combination of so many innovations did not allow further development that wasn't compensated by real progress in terms of armament or firepower, compared to the much cheaper and simpler T-55.

The Object 432

As work continued on the new Object 430U and its 122 mm (4.8 in) smoothbore gun, the Object 432 was started in parallel, with an equally revolutionary 115 mm (4.53 in) D-68 smoothbore gun, for the first time coupled with a fully functional electro-hydraulic autoloading system. This risky featured required less internal space for the two-man turret (commander and gunner), ensuring a much lower silhouette, and almost the weight of a light tank, with only 30 tons compared to 36-38 tons of other projects. However, they had to devise yet another trick to face the new L7/M68 NATO gun, recently unveiled by reports and a captured ex-Iranian M60 tank.

It had the first composite armor on this side of the Iron Curtain. Called "K combination", it apparently combined an aluminum alloy layer sandwiched between two high strength steel layers or glass-reinforced plastic sandwiched between layers of steel. This add-on armor raised the overall weight to 34 tons, well compensated by the new 5TDF engine. This time, Morozov estimated the combination was worth a production and had the greenlight after the first prototype was unveiled in September 1962 and passed all tests successfully. The new tank production was set up in 1963, and the new tank was named T-64, after the year of its introduction into service. This MBT was far more successful than the T-62, especially when comparing their respective mobility.

The T-64A

After the production started, the team worked frantically on a new project, derived from the Object 443U, the Object 434 which would be armed with yet another gun, a much more powerful 125 mm (4.92 in) smoothbore. Superficially, the D-81T from the Perm weapons factory was a scaled-up 122 mm (which equipped the T-62), itself merely a smoothed 115 mm (4.53 in). This 125 mm gun was already produced as a towed AT gun for the army as the 2A45 and was adapted as the 2A46, still fitted with a completely new modified 6ETs10 autoloader. The latter one had the advantage of allowing to carry more rounds for such a big gun and restricted interior space (without, the 122 mm/4.8 in ammo supply would have been reduced to 20-25 rounds max). That freed space from the elimination of the loader allowed to carry 28 rounds.

The T-64A main gun was also given the 2E23 3-pane stabilizer coupled to the new TPD-2-1 night sight, TPN-1-43A night driving periscope for the driver and, in addition, for night combat, the infrared L2G projector, placed just left to the main gun, coaxial, instead of being over the gun like in previous designs. Armor was modified with fiberglass replacing the aluminum alloy and spring-mounted plates (Gill skirt) were added along the mudguards. Additional storage spaces were also added along the turret sides and rear, plus the usual snorkel tubes relocated. A full NBC protection system was provided, while the hatches were modified and widened.

The Object 434 prototypes were tested in 1966-67 and the production started in 1968 after 600 T-64s of the 1st generation had been made. By the 1970s, this influential design had not only earned Alexander Morozov the Lenin Prize but also influenced the T-72 design. Constantly upgraded, the T-64 was given to elite units of the Red Army.

In 1971-72 a new wave of modernization will see the adoption of the TPD-2-49 day sight with optical coincidence rangefinder, the TPN-1-49-23 night sight and new 2E26 stabilizer, driver's TBN-4PA sight and commander TNP-165A. The biggest change was a remotely-operated NSVT 12.7 mm (0.5 in) machine gun, with an optical PZU-5 sight. The KMT-6 anti-mine system was added and a new R-123M radio. The new command tank T-64AK was derived from it, with a long-range R-130M radio, PAB-2AM and TNA-3 navigation station powered by an auxiliary petrol engine. This version derived from the Ob'yekt 446 prototype (1972) had a 10 m (33 ft) telescoping antenna, no AA machine-gun, and only 38 rounds of ammunition.

In 1976 another set of upgraded saw the adoption of the D-81TM tank gun stabilized by the 2E28M2 system, and 6ETs10M autoloader, TNPA-65 night sight. For the first time, the engine was modified to be multi-fuel (it could run either on gasoline, diesel, kerosene), answering the NATO standard. By 1981, two banks of 81 mm (3.19 in) 902A smoke grenade-launchers were added to the turret, while the Gill skirts were replaced by more traditional rubber skirts. Additional upgrades were performed along the T-64B lines in the 1980s, like the adoption of ERA protection and laser TPD-K1 telemeters. The older T-64s were fully modernized in 1977-1981 along the lines of the T-64A, ending as the sub-standard T-64R.

The T-64B

Work started as early as 1961, as a backup plan when it was found that the new 5TDF engine was complicated to make, and therefore had a slow rate of production. The design team tried to fit, in the small engine compartment, the more conventional 12-cylinder V-45 engine. After years of researches and modifications, the three Ob'yekt 436 prototypes were eventually tested in 1968 at the Chelyabinsk factory proving grounds. Other developments led to the four Ob'yekt 439s, which were not produced but served as testbeds for the T-72 design.

In 1973, further studies with the T-64A-2M led to the creation of the Ob'yekt 476, with a new 1100 hp engine (the future T-80 engine compartment was modeled after it) and the Ob'yekt 447, which featured a new laser telemeter and guiding system, allowing to fire ATGMs through the gun. In addition, it had the D-81Tm gun with a 2E26M stabilizer, 6ETs40 autoloader, 1A33 FCS comprising a ballistic calculator, sight with laser telemetry and cross-wind sensor. The ATGMs were eight 9M112 "Kobra" (radio-guided, NATO "AT-8 Songster"). Command tanks were the T-64BK and T-64B1K, with an R-130M radio and its 10 m telescoping antenna, a TNA-3 navigation system and AB-1P/30 APU, without antiaircraft machine gun, carrying 28 shells.

Object 447
The Object 447, now on display at the Great Patriotic war museum.

The Object 447 was produced as the T-64B, and the cheaper Ob'yekt 437 variant, without this ATGM capability, was produced as the T-64B1 (which could carry 37 shells instead of 28). These two tanks also had better fording capabilities (1.8 m). These were accepted for service in September 1976. In 1981, the gun and stabilizer were upgraded and 902A "Tucha-1" smoke grenade launcher added to the turret. In October 1979, a new engine was developed, the 6TD, which could now replace the former 5TDF and, consequently, in the early 1980s, led to further modernization as the T-64AM and BM, and their derivatives like the BM-1 and K command variants. These were the latest produced in USSR, in 1987. The BV was an export version of the T-64B, with a "Kontakt-1" reactive armor and "Tucha" 81-mm smoke grenade launchers (turret left side). It was only sold by Ukraine (as the BV1) to the Democratic Republic of Congo recently. Modernization, however, did not stop after the fall of the USSR, and Ukraine continued on these upgrades packages with the BM2, U and BM Bulat, all active in the Ukrainian armored forces up to this day.

The T-64 specifics

According to the Perret, Bryan book of 1987, "Soviet Armour since 1945" (London: Blandford Press. ISBN 0-7137-1735-1), the T-64 was not only highly innovative and riskily engineered, but it had serious limitations and drawbacks, which limited its adoption by the Warsaw Pact. The price was probably the biggest issue to prevent any export.

Advantages

Autoloader The automatic loader of the T-64 was hydraulic, not electric, and thus much faster (6 to 13 seconds reload time) and much more reliable and less sensitive to off-road damping than the T-62's. Furthermore, the "sequence" fire mode could provide the gun with same type shells in less than five seconds. The modernized version was capable of moving backward to keep a fast pace at the end of the loading sequence.

Improved crew comfort
For the first time in a Russian tank, the crew comfort seemed to have taken attention, starting with far less exhausting drives and appreciable driving comfort, thanks to assisted controls and a more flexible and refined suspension.

Improved crew safety
Reinforced by the relocation of the ammunition stowage to the lower point of the turret shaft, also lowering the risk of detonation.

Improved vision
The tank commander's cupola provided better vision than usual cupolas and better awareness of the battlefield.

Improved firing safety
The AA heavy machine gun could be remotely operated (from inside the turret), which presents some advantages in urban combat. For the first time, the tank commander could also override the gunner and fire the main gun if necessary.

Issues

The autoloader controversy

The adoption of an autoloader presented many advantages, but came with some controversy, due to the experience with the less refined T-62 autoloader. It was dangerous for the crew if the assembly quality was not optimal (rounds bouncing around, jammed mechanics), leading to serious injuries and hot poisonous gas exhausts inside the cramped turret, not to mention the problems that arose if the autoloader was inoperable for some reasons. The gunner had to manually load the gun in an uncomfortable and dangerous position, and with a very slow rate of fire (less than one per minute), critical in the heat of battle.

A crew of three

From a strict military point of view, a crew of three could be a great advantage when having limited manpower. France tested this in the 1930s with almost systematic one-man turret configurations (a tradeover due to a depleted male population and poor birth rate after the losses of the Great War), only to find that an overloaded commander was not favorable on the battlefield. A two-man turret with a commander occupied with his usual tasks allowed a three-man tank to remain fully operational and field more tanks with the same amount of trained crews. But this came at a price, as the crew was also in charge of the tank maintenance and refueling, which was even more exhausting on the complex T-64. Moreover, these duties are also performed at the end of the operations, when the tank crew is physically exhausted, often without an officer, leading to two-men operations and less effective crews on the long run. Maintenance routine, in these cases, had a tendency to be botched or even skipped, which was paid, in return, by higher risks of mechanical failure. These aspects are further exacerbated in active combat operations.

Complexity

Unlike most Russian tanks, simple and rugged, the T-64 was a very complex and unusually care-sensitive machine. This, combined with summary maintenance habits and reduced crew, resulted in a very high breakdown rate at the beginning. The brand new suspension system, a quite advanced design, necessitated the permanent presence of teams of civilian mechanics from factories to assist the unit for the first years after its adoption and delayed a widespread adoption in operational frontline units until the 1970s, and only with proper maintenance procedures. The engine itself was also troublesome, and entire units stationed in East Germany and Hungary were sometimes depleted of 30 tanks in a single year, the equivalent of a whole battalion. Complaints numbers reached the military wing of the central committee. Alexander Morozov himself was blamed, but the military school was able to train a new generation of young officers, able to deal with all aspects revolving around this new tank. This generation was able to make the transition between the "old school mass produced" generation MBTs, to those accustomed to a fewer and high engineered third-generation main battle tanks, like the T-80 and T-90, plus better-trained crews, but the T-64 triggered all this.

The Ukrainian variants (1990-2000s)

The end of the Cold War allowed the T-64 to keep up with the latest technologies, right up to the XXIst century. These developments were greatly helped by the presence of the original factory and its numerous facilities on Ukrainian soil.

The T-64BM2

This version received a brand new 57DFM multi-fuel engine capable of 850 hp (625 kW), a new 1A43U fire control system, a new 6ETs43 autoloader and a system enabling the use of the light 9M119 AT missile ("AT-11 Sniper"). Armor is upgraded to the Kontakt 5 ERA standard.

The T-64U

This model is based on the latter, but received a new 1A45 fire control system borrowed from the T-80U/T-84, the tank commander PNK-4SU and TKN-4S all-weather NV optics, and an anti-aircraft PZU-7 AA sight for the heavy machine gun. The tank commander is given the possibility to fire the gun directly if the gunner was incapacitated. The standard protection is provided by a Kontakt-5 explosive reactive armor set, and apparently upgraded only on a few prototypes. Both the BM2 and U are in the process of being re-engineered with the new 6TDF 1000 hp (735 kW) engine.

The T-64BM Bulat

Based on the BM2, this version integrates the Ukrainian designed Knozh reactive armor, a well improved version of Kontakt-5, apparently giving better overall protection against tandem warheads, and also equipped with the new Ukrainian main gun 125 mm (4.92 in) gun KBA3. It is also equipped with the advanced TO1-KO1ER night sight and compatible with the Ukrainian KOMBAT missile system, which uses tandem warheads. It basically brings the T-64B to the standard of the T-84 with "Nozh" reactive armor, 9K120 "Refleks" missile (NATO code "AT-11 Sniper"), 1A45 "Irtysh" fire control, TKN-4S commander's sight and PZU-7 AA HMG sight plus TPN-4E "Buran-E" night vision and a 6TDF 1000-hp (735 kW) engine.

Production & variants

Due to the program secrecy, the sources are differing considerably about the total production, at least in the initial period of 1963-1967. In practice, the first T-64s had the same 115 mm (4.53 in) smoothbore gun as the T-62, but mass-production models were all equipped with the 125 mm (4.92 in) gun, compatible with T-72 ammunition. The T-64 was, however, much more complex and costlier than the T-72, and did not see much active service outside the USSR or Russia.

Experimental variants

  • T-64R (remontirniy or rebuilt)/Ob\'yekt 432R (1977-1981), tested with the T-64A standard, but with the 115 mm (4.53 in) gun.
  • T-64T (1963), testing a GTD-3TL 700 hp (515 kW) gas turbine.
  • Ob'yekt 436, alternative version with the V-45 engine, three prototypes built.
  • Ob'yekt 437 prototype for the B1, without the FCS and only carrying 37 shells.
  • Ob'yekt 438/439 based on the Ob'yekt 434, but with the V-45 diesel engine.
  • Ob'yekt 446B prototype for the BK and B1K command versions.
  • Ob'yekt 447, prototype for the T-64B series, with the 9K112 "Kobra" system and a1G21 gunsight.
  • Ob'yekt 447AM-2, prototype for the BM2 series. Kontak-5 ERA, rubber skirts, 1A43U FCS, 6ETs43 loader, 9K119 missile enabled, 5TDFM engine.
  • Ob'yekt 447AM-1, prototype for the Ukrainian "Bulat" version.
  • Ob'yekt 476, five prototypes with the 6TDF engine, prototypes for T-80UD development.
  • T-55-64, experimental hybrid of an upgraded T-55 with the hull and chassis of a T-64, and "Kontakt-1" ERA.

Ukrainian specialized variants

BREM-64

Derived from the Ob'yekt 447T – armored recovery vehicle (ARV) with a light 2.5-tonne crane, a dozer blade, tow bars and welding equipment. A few were built.

BMPV-64

Heavy infantry fighting vehicle (IVF) with completely redesigned upper hull featuring a single rear entry hatch, remote-controlled 30 mm (1.18 in) gun and 34.5 tons heavy. First tried in 2005, but limited production so far for testing and evaluation. The BTRV-64 is an APC version, also semi-experimental.

UMBP-64

New redesigned chassis for several (planned) specialized vehicles (fire support, ambulance air-defense vehicles).

BMPT-K-64

Completely overhauled chassis with 4 axles roadwheels, like the BTR series. The engine is the 5TDF-A/700, for a combat weight of only 17.7 tons. RCWS and a capacity of a platoon or eight equipped infantrymen inside. This prototype did not lead to a production run so far.

BAT-2

A fast combat engineering vehicle sharing the engine, lower hull and suspension with the T-64, but with a large all axis adjustable V-shaped hydraulic front dozer blade, single soil ripper spike at the rear and 2-ton crane on top. 8 crew cabin (five-man sapper squad for dismounted tasks added to the normal crew). 40 ton, only limited production due to a high price tag.

Ukrainian heavy IFV/APC designs

With large surplus of T-64s, the Ukrainian design bureau of the Kharkiv Armor Repair Plant (Zavod 311) tried to use its chassis as a basis for a whole family of combat and support vehicles, aimed for the export market. The engine compartment is moved forward and the fighting compartment removed (as well as the turret). Up to 15 "functional modules", weighing up to 22 tons can then be inserted, turning the chassis into many new variants. The BMP-64E heavy IFV can carry 10 infantrymen with a remote weapons system. The heavy APC version BTR-64E can carry up to 16 infantrymen, which can exit through large armored double hatches at the rear. A universal supply carrier UMBP-64, a HQ vehicle and a 120 mm (4.72 in) mortar carrier are also on the conversion list. No orders were registered yet.

Operators

Soviet Union tanks were passed onto the successor states, Russia, Belarus, Ukraine, and Uzbekistan.

Russia had approximately 4000 tanks in service in 1995, either in reserve or active duty. 2000 were phased out of service and stored for scrapping in the 2000s. According to NATO International and Jen Psaki unmarked T-64 tanks were used by pro-Russian separatists in Ukraine in mid 2014.
Ukraine had 2345 tanks in service as of 1995, but only 2215 in 2005, and around 600 today (modernized), while 900 are in storage for export, conversion and reserve. 100 of these were completely modernized to the T-64BM Bulat standard.
Donetsk People's Republic Insurgents allegedly deployed around twenty tanks from the Russian army stocks, involved in the summer fighting.
Transnistria Between ten an fifteen T-64BVs are reported in service.
Uzbekistan A hundred T-64s (unknown version) were reported in service as of 2013.
Belarus operated an unknown numbers in the 1990, scrapped since.
The Democratic Republic of the Congo received 50 T-64BV-1 from the Ukrainian Ukrspetsexport in February 2014, the only non-CEI country to operate this tank as of today.

Active service

Despite being produced since 1963, the T-64 only entered formal service with the Red Army in 1967, with the 41st Guards Tank Division in the Kiev Military District (according to David Isby) and was only publicly revealed in 1970. It was capable of replacing the IS-3 and T-10 heavy tanks in independent tank battalions. However, the proximity of the division to the factory was not random, but linked with anticipated teething problems during the introduction of these new technologies. Factory support personnel was indeed a regular presence with the division during the service acceptance of this new tank. This period also allowed to train personnel and crews to the new model features, and devise adapted procedures. At the same time, the simpler T-72 replaced the T-55 and T-62, which formed the bulk of Soviet armored forces, the Warsaw pact and its satellites. The T-64 was definitely a breed apart, introducing many innovations. Due to its high-price tag, it never was intended for export, and was only given to the Red Army elite units and the best trained crews. Entire maintenance and drilling procedures had to be tailored, in a 10-15 years long process. T-64 equipped units were kept in operational readiness in case of a potential outbreak of war in Europe, stationed in East Germany and Hungary.

Decontamination exercize

According to official records, the T-64 was never used in the Soviet War in Afghanistan. although it is still possible that a small number of these tanks were tested in "quieter" areas of the front. The Russian T-64s of the 59th Guards Motor Rifle Division in Moldova saw action in May 1992, although the events did not lead to any shots being fired. T-80s participated in the First Chechen War, but the presence of T-64s alongside T-72s and T-62s is only hypothetical.

The Ukrainian civil war
This recent conflict saw the T-64 heavily engaged for the first time, in mid-2014 in the Donbass area. The Ukrainian Army deployed T-64s in the offensive against pro-Russian separatists. Over 20 T-64 tanks were also operated by the military forces of Novorossiya in August. Ukrainian and NATO officials claimed that these T-64s were supplied to the separatists by Russia. Over seventeen T-64s of various configurations (including three T-64BM Bulats) were reported as destroyed by official sources.

The Ukrainian T-64s
76 T-64BM "Bulat" were reported in service in October 2011. The Kharkiv Malyshev Factory upgraded ten T-64B to the BM "Bulat" standard in 2010, and 19 more in 2011 for less than 200 million Hryvnia ($25.1 million). The contract was signed in April 2009. The "Bulat" produced at Kharkiv, then Malyshev Factory, have protection of comparable level to modern western tanks, according to the chief of the design bureau. This is due to the combination of "Knife" reactive armor, and "Warta" active defense system. For its 45 tonnes and 850 hp, the Bulat can reach 70 km/h (43.5 mi) on flat ground for a range of 385 km (239 miles). Its numerous types of 125 mm (4.92 in) ordnance include guided missiles. In February 2014 it was learned that the factory concluded a deal with for 50 T-64BV1 to Congo, the first export to a country outside former USSR operators.
