suspension, a novel transverse engine mount, and the removal of the hull machine-gunner's crew position, the T-44 had cross country performance at least as good as the T-34, but with substantially superior armour and a much more powerful 85 mm gun.
By the time the T-44 was ready for production, the T-34 had also been modified to fit the same gun. Although the T-44 was superior in most other ways, by this time T-34 production was in full swing and the massive numbers of T-34s being built offset any advantage to smaller numbers of a superior design. The T-44 was produced in only small numbers, around 2,000 being completed during the war. Instead, the designers continued to use the design as the basis for further improved guns, experimenting with a 122 mm design, but later deciding a 100 mm gun was a better alternative.
Prototypes
Efforts to fit the 100 mm gun to the T-44 demonstrated that small changes to the design would greatly improve the combination. The main issue was a larger turret ring, which suggested slightly enlarging the hull. A prototype of the new design, about longer and only 10 cm wider, was completed in 1945. This model looked almost identical to the original T-44, albeit with a much larger gun. In testing, there were several drawbacks that needed correcting and many alterations that had to be made to the vehicle's design. It was decided to begin serial production of the new vehicle and the vehicle officially entered service in April 1946. It would go into production inNizhny Tagil

Production of the initial series of T-54s began slowly as 1,490 modifications were made. The Red Army received a tank that was superior to World War II designs and theoretically better than the newest tanks of potential opponents. The 100 mm gun fired BR-412 series full-calibre APHE ammunition, which had superior penetration ability when compared to the T-34 that it replaced.
The serial production version, designated T-54-1, differed from the second T-54 prototype. It had thicker hull armour (80 mm on the sides, 30 mm on the roof and 20 mm on the bottom). As production ramped up, quality problems emerged. Production was stopped and an improved T-54-2 (''Ob'yekt'' 137R) version was designed. Several changes were made and a new turret was fitted. The new dome-shaped turret with flat sides was inspired by the turret from the IS-3 heavy tank; it is similar to the later T-54 turret but with a distinctive overhang at the rear. It also had a shorter bustle.
The fender machine guns were removed in favour of a single bow-mounted machine gun. The transmission was modernised and the track was widened to 580 mm. The T-54-2 entered production in 1949, at Stalin Ural Tank Factory No. 183 (Uralvagonzavod). In 1951, a second modernization was made, designated T-54-3 (''Ob'yekt'' 137Sh), which had a new turret without side undercuts, and the new TSh-2-22 telescopic gunner's sight instead of the TSh-20. The tank featured the TDA smoke generating system. A command version was built, the T-54K (''komandirskiy''), with a second R-113 radio.Zaloga 2004, p. 11.

In its long service life, the T-55 has been upgraded many times. Early T-55s were fitted with a new TSh-2B-32P sight. In 1959, some tanks received mountings for the PT-55 mine clearing system or the BTU/BTU-55 plough. In 1967, the improved 3BM-8 APDS round, which could penetrate 275 mm thick armour at a range of 2 km, was introduced. In 1970, new and old T-55 tanks had the loader's hatch modified to mount the 12.7 mm

T-54A and T-54B
In the beginning of the 1950s, the personnel of the OKB-520 design bureau of the Stalin Ural Tank Factory No. 183 (Uralvagonzavod) had been changed considerably. Morozov was replaced by Kolesnikow, who in turn was replaced by Leonid N. Kartsev in March 1953. The first decision of the new designer was to fit the 100 mm D-10T tank gun with the STP-1 "Gorizont" vertical stabilizer. The new tank gun received the designation D-10TG and was fitted into the T-54's turret. The new tank received night vision equipment for the driver and was designated T-54A (''Ob'yekt'' 137G). Originally, this had a small muzzle counter-weight, which was later replaced with afume extractor

. It was equipped with an OPVT wading snorkel, the TSh-2A-22 telescopic sight, TVN-1 infrared driver's periscope and IR headlight, a new R-113 radio, multi-stage engine air filter and radiator controls for improved engine performance, an electrical oil pump, a bilge pump, an automatic fire extinguisher and extra fuel tanks.
The tank officially entered production in 1954 and service in 1955. It served as a basis for T-54AK command tank, with additional R-112 radio set (front line tanks were equipped with R-113 radio set), TNA-2 navigational device, ammunition load for the main gun decreased by 5 rounds and the AB-1-P/30 charging unit, which was produced in small numbers. In October 1954 a T-54A tank, designated as T-54M (''Ob'yekt'' 139) served as a testbed for new D-54T and D-54TS 100 mm smoothbore guns and "Raduga" and "Molniya" stabilization systems, which were later used in the T-62. These were not completely successful, so further T-55 development continued to use the D-10 series guns. It was fitted with V-54-6 engine developing 581 hp (433 kW). It never went into production.
A new version, based on T-54A, designated T-54B (''Ob'yekt'' 137G2), was designed in 1955. It was fitted with a new 100 mm D-10T2S tank gun with STP-2 "Tsyklon" 2-plane stabilizer. It entered production in 1957. During the last four months of production, the new tanks were equipped with an L-2 "Luna" infrared searchlight, a TPN-1-22-11 IR gunner's sight, and an OU-3 IR commander's searchlight. Modern APFSDS ammunition was developed, dramatically enhancing the penetrative performance of the gun to keep it competitive with NATO armour developments. T-54B served as the basis for T-54BK command tank, which had exactly the same additional equipment as the T-54AK command tank.

system offering protection against the blast of a nuclear weapon and (radioactive) particulate filtration, but not against external gamma radiation or gas, was given to the KB-60 design bureau in Kharkiv and was completed in 1956. The documentation was sent to Uralvagonzavod. It was decided to increase the tank's abilities by changing its construction and introducing new production technologies. Many of those changes were initially tested on the T-54M (''Ob'yekt'' 139).
The tank was fitted with the new V-55 12-cylinder four-stroke one-chamber, 38.88-litre water-cooled diesel engine developing 581 hp (433 kW). Engine power was increased by raising the pressure of the fuel delivery and charging degree. The designers planned to introduce a heating system for the engine compartment and MC-1 diesel fuel filter. The engine was to be started pneumatically with the use of an AK-150S charger and an electric starter. This eliminated the need for the tank to carry a tank filled with air. To allow easier access during maintenance and repairs, it was decided to change hatches over the engine compartment. To increase the operational range, fuel tanks were added to the front of the hull, increasing the overall fuel capacity to .
The ammunition load for the main gun was increased from 34 to 45, with 18 shells stored in so-called "wet containers" located in hull fuel tanks (the concept for which came from Kartsev's cancelled ''Ob'yekt'' 140). The ammunition load included high explosive-fragmentation and anti-tank rounds and designers also planned to introduce the BK5M high-explosive anti-tank

(HEAT) rounds which penetrated thick armour. The TPKU commander's vision device was replaced by either the TPKUB or TPKU-2B. The gunner received a TNP-165 vision device.
The loader's hatch-mounted 12.7 mm DShK anti-aircraft heavy machine gun was dropped, because it was deemed worthless against high-performance jets. The tank was supposed to be equipped with the "Rosa" fire protection system. The tank had a thicker turret casting and the improved two-plane gun stabilization system from the T-54B, and night vision fighting equipment. To balance the weight of the new equipment, the armour on the back of the hull was thinned slightly.
The T-55 was superior to the IS-2

, IS-3, and T-10 heavy tanks in many respects, including the rate of fire of the gun (at least four compared to fewer than three rounds per minute). Despite somewhat thinner frontal turret armour ( instead of ) it compared favourably with the IS-3, due to its improved antitank gun and better mobility. Heavy tanks soon fell from favour, with only 350 IS-3s produced.Sewell, Stephen, CW2 (rtd). "Why Three Tanks?" (''Armor'', July–August 1998), p. 26.
The old model of highly mobile medium tanks and heavily armoured heavy tanks was replaced by a new paradigm: the "main battle tank

". Parallel developments in the West would produce similar results. Kartsev combined all the ongoing improvements being offered, or planned, on the T-54 into one design. This became the ''Ob'yekt'' 155, and entered production at Uralvagonzavod 1 January 1958 as the T-55.Sewell, p.27. It was accepted for service with the Red Army on 8 May. It suffered a significant lapse in one area: there was no antiaircraft machine gun, which had been present on the T-54.
After 1959, it served as a basis for the T-55K command tank which was equipped with an additional R-112 radio set, an AB-1-P/30 fuel powered accumulator charging unit, and TPN-1-22-11 night vision sight. All this additional equipment made it necessary to decrease the ammunition load for the main gun to 37 rounds and eliminate the bow machine gun. In the beginning of the 1960s, a T-55K was experimentally fitted with a ''Uran'' TV relay apparatus for battlefield surveillance. The tank was fitted with an external camera, the picture from which was relayed to a receiver in a BTR-50PU command vehicle. There was an observation camera mounted on a folding mast which was in turn mounted on a UAZ 69

car. The range within which the picture could be relayed varied between .
In 1961, a T-55 tank was used to test the "Almaz" TV complex, which was supposed to replace the standard observation devices right after a nuclear explosion or while fording a body of water. There was a camera mounted on the hull for the driver and two cameras mounted on the turret, one for aiming and one for observation, and the picture from the cameras was relayed to two control screens. The tank had the front hull fuel tanks and bow machine gun removed. The commander was seated in the driver's usual position while the driver sat next to him.
The cameras allowed battlefield observation and firing during daytime at ranges between . Because of the low quality of the equipment, the trials gave negative results. In the beginning of the 1960s, the OKB-29 design bureau in Omsk
Omsk (; rus, Омск, p=omsk) is the administrative center and largest city of Omsk Oblast, Russia. It is situated in southwestern Siberia, and has a population of over 1.1 million. Omsk is the third largest city in Siberia after Novosibirsk ...
was working on adapting the tank to use a GTD-3T gas turbine engine developing 700 hp (522 kW). One T-55 tank fitted with this gas turbine engine passed trials but was deemed unsatisfactory and the design did not go into production.
The Omsk OKB-29 group tested three experimental T-55 tanks (designated ''Ob'yekt'' 612) between 1962 and 1965 that were fitted with an automatic gearbox controlled by electro-hydraulic systems. The trials found that such gearboxes were prone to frequent breakdowns in tanks. At the same time the ''Ob'yekt'' 155ML, a T-55 fitted with a launcher for three 9M14 "''Malyutka''" (NATO code: AT-3 Sagger) ATGMs

mounted on the rear of the turret, was tested. Along with standard tanks a flamethrower-armed version was designed (designated TO-55 (''Ob'yekt'' 482)), which was produced until 1962. It was fitted with 460-litre tanks filled with flammable liquid instead of the frontal hull fuel tanks. The flamethrower replaced the coaxial machine gun. This was a much better way to mount a flamethrower than in the experimental ''Ob'yekt'' 483, based on the T-54 tank, where the flamethrower replaced the main gun. TO-55 flamethrower tanks were withdrawn from service in 1993.

In 1961, development of improved NBC protection systems began. The goal was to protect the crew from fast neutrons; adequate protection against gamma radiation was provided by the thick armour and a PAZ basic NBC protection system. The POV plasticized lead antiradiation lining was developed to provide the needed protection. It was installed in the interior, requiring the driver's hatch and thecoaming

. The hull was lengthened from 6.04 m to 6.2 m. The hull machine gun was removed, making space for six more main gun rounds. These changes increased the weight of the vehicle to 38 tonnes.
The design work was done by OKB-520 design bureau of Uralvagonzavod under the leadership of Leonid N. Kartsev. The T-55A served as the basis for the T-55AK command tank.
T-54/T-55 upgrades
In its long service life, the T-55 has been upgraded many times. Early T-55s were fitted with a new TSh-2B-32P sight. In 1959, some tanks received mountings for the PT-55 mine clearing system or the BTU/BTU-55 plough. In 1967, the improved 3BM-8 APDS round, which could penetrate 275 mm thick armour at a range of 2 km, was introduced. In 1970, new and old T-55 tanks had the loader's hatch modified to mount the 12.7 mm DShK machine gun

During production, the T-55A was frequently modernised. In 1965, a new track was introduced that could be used for between 2,000 km and 3,000 km, which was twice the range of the old track. It needed a new drive sprocket, with 14 teeth instead of 13. Since 1974, T-55A tanks were equipped with a KTD-1 "Newa" rangefinder and a TSzS-32PM sight. All T-55A tanks were equipped with the TPN-1-22-11 night sight. The R-113 radio set was replaced by a R-123 radio set. Late production models had rubber side skirts and a driver's windshield for use during longer stints.

and a prototype named the Jaguar was produced. The Jaguar looked quite different from its predecessors. A newly designed turret was formed by flat armour plates installed at different angles. The hull top was new. The engine compartment and fuel tanks on the shelves over the tracks were armour-protected. The Soviet-made 100 mm gun was replaced with the American M68 105 mm rifled gun fitted with a thermal sleeve. A Marconi fire control system which was originally developed for the American light tank Stingray was fitted. The vehicle incorporated a Cadillac-Gage weapon stabilizer and gunner's sight equipped with an integral laser rangefinder. The power pack inherited by the Jaguar from the Stingray underwent only minor alterations and comprised the Detroit Diesel 8V-92TA engine and XTG-411 automatic transmission. In 1989, two Jaguar tanks were manufactured. The chassis were provided by PRC, while the hull tops, turrets and powerplants were manufactured by Cadillac Gage Textron.

The T-54 and T-55 tanks are outwardly very similar and difficult to distinguish visually. Many T-54s were also updated to T-55 standards, so the distinction is often downplayed with the collective name ''T-54/55''. Soviet tanks were factory-overhauled every 7,000 km and often given minor technology updates. Many states have added or modified the tank's equipment; India, for example, affixed fake fume extractor

The older T-54 can be distinguished from the T-55 by a dome-shaped ventilator on the front right of the turret and a driver-operated SGMT 7.62 mm machine gun mounted to fire through a tiny hole in the center of the hull's front. Early T-54s lacked a gun fume extractor, had an undercut at the turret's rear, and a distinctive "pig-snout" gun mantlet
A gun mantlet is an armour plate or shield attached to an armoured fighting vehicle's gun, protecting the opening through which the weapon's barrel projects from the hull or turret armour and, in many cases, ensuring the vulnerable warhead of a ...

Advantages and drawbacks
The T-54/55 tanks are mechanically simple and robust. They are very simple to operate compared to Western tanks, and do not require a high level of training or education in their crewmen. The T-54/55 is a relatively small main battle tank, presenting a smaller target for its opponents to hit. The tanks have good mobility thanks to their relatively light weight (which permits easy transport by rail or flatbed truck and allows crossing of lighter bridges), wide tracks (which give lower ground pressure and hence good mobility on soft ground), a good cold-weather start-up system and a snorkel that allows river crossings. According to Zaloga, "By the standards of the 1950s, the T-54 was an excellent tank combining lethal firepower, excellent armour protection and good reliability" while remaining a significantly smaller and lighter tank than its NATO contemporaries—the US M48 Patton tank and the British Centurion tank. The 100 mm D-10T tank gun of the T-54 and the T-55 was also more powerful than its Western counterparts at that time (the M48 Patton initially carried a 90 mm tank gun and the Centurion Mk. 3 carried the 20-pounder (84 mm) tank gun). This advantage lasted until the T-54 began to be countered by newer Western developments like the M60 main battle tank and upgraded Centurions and M48 Pattons using the 105 mm rifled Royal Ordnance L7 or M68 gun. Due to the lack of a sub-caliber round for the 100 mm gun, and the tank's simple fire-control system, the T-54/55 was forced to rely on HEAT ammunition to engage tanks at long range well into the 1960s, despite the relative inaccuracy of this ammunition at long ranges. The Soviets considered this acceptable for a potential European conflict, until the development ofcomposite armour

began reducing the effectiveness of HEAT warheads and kinetic energy penetrator sabot rounds were developed for the D-10T gun.
Nevertheless, T-54/55 tanks had their drawbacks. Small size is achieved at the expense of interior space and ergonomics, which causes practical difficulties, as it constrains the physical movements of the crew and slows operation of controls and equipment. This is a common trait of most Soviet tanks and hence height limits were set for certain tank crew positions in the Soviet Army, whereas other armies may not include crew member height limits as standards.
The low turret profile of the tanks prevents them from depressing their main guns by more than 5° since the breech would strike the ceiling when fired, which limits the ability to cover terrain by fire from a hull-down

position on a reverse slope. As in most tanks of that generation, the internal ammunition supply is not shielded, increasing the risk that any enemy penetration of the fighting compartment could cause a catastrophic secondary explosion. The T-54 lacks NBC protection, and a turret basket, which meant that crewmen had to physically rotate and keep up with a rotating turrent as the hull in which they stood didn't move with the turret. Additionally, early models also lacked gun stabilization. Most of these problems were corrected in the otherwise largely identical T-55 tank.
Together, the T-54/55 tanks have been manufactured in the tens of thousands, and many still remain in reserve, or even in front-line use among lower-technology fighting forces. Abundance and age together make these tanks cheap and easy to purchase.
Production history
Soviet Union
T-54-1 production was slow at first, as only 3 vehicles were built in 1946 and 22 in 1947. 285 T-54-1 tanks were built in 1948 by Stalin Ural Tank Factory No. 183 (Uralvagonzavod

); by then it had completely replaced T-44 production at Uralvagonzavod, and Kharkiv Diesel Factory No. 75 (KhPZ). Production was stopped because of a low level of production quality and frequent breakdowns. The T-54-2 entered production in 1949 at Uralvagonzavod, which produced 423 tanks by the end of 1950. It replaced the T-34 in production at the Omsk Factory No. 183 in 1950. In 1951, over 800 T-54-2 tanks were produced. The T-54-2 remained in production until 1952. The T-54A was produced between 1955 and 1957. The T-54B was produced between 1957 and April 1959. The T-55 was produced by Uralvagonzavod between 1958 and 1962. The T-55K command tank was produced from 1959. The TO-55 (''Ob'yekt'' 482) flamethrower tank was produced until 1962.
Overall 35,000 T-54-1, T-54-2, T-54 (T-54-3), T-54A, T-54B, T-54AK1, T-54AK2, T-54BK1 and T-54BK2 tanks were produced between 1946 and 1958 and 27,500 T-55, T-55A, T-55K1, T-55K2, T-55K3, T-55AK1, T-55AK2 and T-55AK3 tanks were produced between 1955 and 1981.
Poland
Poland produced 3,000 T-54, T-54A, T-54AD and T-54AM tanks between 1956 and 1964 and 7,000 T-55 (between 1964 and 1968), T-55L, T-55AD-1 and T-55AD-2 tanks (between 1968 and 1979).

During the Vietnam war, NVA tank units were involved in 211 battles, claimed 20,000+ enemy killed, destroyed more than 2,000 enemy tanks/APCs, 870 other military vehicles, and 3,500 enemy bunkers, and shot down 35 aircraft or helicopters, overwhelmingly using T-54s. The NVA lost an estimated 250 (1972 - 150, 1973-1975 - 100) T-54s during the war.
Following the Vietnam War, Vietnam's T-54/55s and Type 59s continued to see much combat activity against neighbouring Cambodia and China to their north between 1978 and 1979. Just like many developing countries around the world which continue to operate the T-54/55, at least 900 T-54s, along with a similar number of T-55s and Type 59s, are still in active military service with the Socialist Republic of Vietnam

Six T-55s were lost (three to RPGs, three to Olifants, one more was damaged), but the attack blunted the South African advance, safeguarding the cohesion of the Angolan line. Cuban and Soviet sources maintain that they destroyed ten Olifant tanks and twelve Ratels, while South African and Western sources maintain that only one Olifant and one Ratel were damaged, and one Ratel destroyed.

Operators and variants
The T-55 has been used worldwide by as many as 50 countries and quasi-armies. They have been subject to many improvements throughout their production history and afterward, and many are still in service today. Modifications to the T-54/55 series over the years have changed almost every aspect of the vehicle. Initially, Soviet modifications included a better turret shape, improved NBC protection and an improved powerplant. Later, improved fire-control equipment and night-vision equipment was added. Foreign improvements, both in Warsaw Pact nations and elsewhere, have further improved protection, powerplant, and firepower. T-54/55s have been re-armed with improved tank guns, AA machine guns, advanced armour arrays, and technologies, such as laser range finders and computerized fire control systems, that did not exist when the tank was first being built in the early days of theCold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because the ...
