The T-10 (also known as Object 730 or IS-8) was a Soviet heavy tank of the Cold War, the final development of the IS tank series. During development, it was called Object 730. It was accepted into production in 1953 as the IS-8 (Iosif Stalin, Russian form of Joseph Stalin), but due to the political climate in the wake of Stalin's death in 1953, it was renamed T-10. [1]
The biggest differences from its direct ancestor, the IS-3, were a longer hull, seven pairs of road wheels instead of six, a larger turret mounting a new gun with fume extractor, an improved diesel engine, and increased armour. General performance was similar, although the T-10 could carry more ammunition, from 28 rounds to 30 rounds.
T-10s (like the IS tanks they replaced) were deployed in independent tank regiments belonging to armies, and independent tank battalions belonging to divisions. These independent tank units could be attached to mechanized units, to support infantry operations and perform breakthroughs.
In 1948 the Soviets had three different kinds of heavy tanks in service sharing little except for road wheels and guns: The IS-2 was the most mechanically reliable, but was becoming obsolete with Western countries such as United States and the United Kingdom fielding newer heavy tanks. The IS-3 was plagued with construction and mechanical problems, and the IS-4 was too heavy to cross bridges in Europe and relegated to the Russian Far East region as result. [2] Kotin personally led a design team to work on project Object 730 to meet the GBTU (Main Armored Vehicle Directorate) requirements for a new heavy tank: it had to be better than the IS-2 and weight no more than 50 metric tons. [2]
The T-10 features a cast hull divided into three compartments, with the driver at the front, the fighting in the center and the engine at the rear. [3] The hull floor features a stamped steel plate in a shallow V shape. [2] The driver sits on the center of the hull and is provided with a hatch cover while the hatch itself features an integral periscope that can be replaced with an infrared one for night driving. The turret is made of rolled steel with the commander and gunner on the left and the loader on the right. Both the commander and loader are provided with hatch covers. A ventilation dome is mounted forward of the two hatch covers. [4]
The T-10 uses the same engine of the IS-4, and reportedly was difficult to replace in the field. [5] According to Sewell the engine was more stressed in comparison to the IS-3. [2] Stowage boxes are mounted on the sides of the hull above the tracks and additional fuel tanks can be fitted at the rear to increase the tank operational range. [5]
The torsion bar suspension consists of seven road wheels with six shock absorbers fitted to each side. [5] A 12.7 mm DShK machine gun is mounted coaxially and an additional DShK was mounted on the loader's hatch ring for anti-aircraft defence. [2] [5]
In 1955 the T-54 tank (designed by the Morozov Design Bureau) and the T-10 were fitted with stabilizers to allow them to fire on the move. While earlier Soviet stabilizers made unnecessary for the gunner to wait until the gun stopped wobbling before engaging his targets, they didn't provided the ability of accurately hitting targets on the move. The T-54 would eventually receive the STP-2 "Tsiklon" (Cyclone) stabilizer while the T-10 was fitted with the PUOT-2 "Grom" (Thunder) stabilizer. While a T-54 gunner only needed to point and fire the gun once he had a stable picture of the target on his sights, the T-10 gunner had to wait for the gun and sight to be stabilized together, slowing down the firing rate. [6]
While the T-10 had thicker armor than the T-54, it suffered from a low rate of fire of three rounds per minute due the use of separate loading ammunition, limited gun depression (a common feature of Soviet tanks), a limit of 30 rounds of ammunition for the main gun, lack of internal space for the crew, and lack of cross-country mobility. [3] The T-10 had an operational range of 180–280 kilometres (110–170 mi) on roads, which was considerably shorter than the T-54, which had a range of over 400 km (250 mi) and the T-55, which could drive 500–700 km (310–430 mi) with 400 litres (88 imp gal; 110 US gal) of auxiliary fuel. [7]
The mobile nature of armoured warfare in World War II had demonstrated the drawbacks of the slow heavy tanks. In the final push towards Berlin, mechanized divisions had become widely split up as heavy tanks lagged behind the more mobile T-34s. The Soviets continued to produce heavy tanks for a few years as part of the Cold War arms race (compare the heavier U.S. M103 and British Conqueror), but the more flexible T-62 and T-64 tanks already had armour and armament comparable to the T-10s.
In the 1960s, the Soviets embraced the main battle tank (MBT) concept, by replacing heavy tanks with mobile medium tanks. In the late 1960s, the independent tank battalions with heavy tanks were re-equipped with the higher-technology T-64s, and later, the very fast T-80, while regular tank and mechanized units fielded the more basic T-55s and T-72s. T-10 production was stopped in 1966, and heavy tank projects were cancelled, such as the auto-loaded, 130 mm-armed Object 770. [8]
Antitank guided missiles (ATGMs) started to be deployed widely during this period, and would become an effective replacement for the heavy tanks' long-range firepower. The Soviets made use of them first on BMP-1 infantry fighting vehicles, and later on the T-64 and other MBTs. Eventually, lighter and more modern reactive or composite armour was used to give the MBTs a further edge in protection without slowing them down.
The T-10 underwent a number of designation changes during its design process starting in 1944 and ending its acceptance into service as the T-10. [9]

The T-10 served with the Soviet Union but was not known to have been provided to Warsaw Pact nations, though Soviet heavy tank regiments stationed in those countries may have been equipped with them. Prior to 1962, T-10Ms were in simultaneous production by two factories (Kirov as Object 272 and Chelyabinsk as Object 734) whose parts were incompatible with those of the other; Kirov's version was standardized in 1962. [12]
Some Western sources claim that the T-10M was exported to countries such as China, Egypt, and Syria, [13] with Syria and Egypt using it in the Yom Kippur War to provide long-range support to the T-55 and T-62, with said sources claiming that the T-10s knocked out several M48 Pattons with none lost, indicating that the T-10 was used to some degree of combat success. However, the T-10 could have been mistaken for its similar counterpart, the IS-3. Heavy tanks were withdrawn from Soviet front-line service by 1967, and entirely removed from reserve service by 1996. [14]
It is estimated that some 6,000 Soviet heavy tanks were built after the end of World War II, of which 1,439 were T-10s. [15]

The T-72 is a family of Soviet main battle tanks that entered production in 1973. The T-72 was a development based on the T-64 using thought and design of the previous Object 167M. About 25,000 T-72 tanks have been built, and refurbishment has enabled many to remain in service for decades. It has been widely exported and has seen service in 40 countries and in numerous conflicts. The Russian T-90 introduced in 1992 and the Chinese Type 99 are further developments of the T-72. Production and development of various modernized T-72 models continues today. Currently holds the record for the most MBT's lost in combat.
The IS tanks were a series of heavy tanks developed as a successor to the KV-series by the Soviet Union during World War II. The IS acronym is the anglicized initialism of Joseph Stalin. The heavy tanks were designed as a response to the capture of a German Tiger I in 1943. They were mainly designed as breakthrough tanks, firing a heavy high-explosive shell that was useful against entrenchments and bunkers. The IS-2 went into service in April 1944 and was used as a spearhead by the Red Army in the final stage of the Battle of Berlin. The IS-3 served on the Chinese-Soviet border, the Hungarian Revolution, the Prague Spring and on both sides of the Six-Day War. The series eventually culminated in the T-10 heavy tank.
The Kliment Voroshilov tanks are a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt German formations. The German Wehrmacht at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the "Russischer Koloss" – "Russian Colossus".
The T-80 is a main battle tank (MBT) that was designed and manufactured in the former Soviet Union and manufactured in Russia. The T-80 is based on the T-64, while incorporating features from the later T-72 and changing the engine to a gas turbine. When it entered service in 1976, it was the first production tank to be powered solely by turbine.
The SU-152 is a Soviet self-propelled heavy howitzer used during World War II.
The ISU-152 is a Soviet self-propelled gun developed and used during World War II. It was unofficially nicknamed Zveroboy in response to several large German tanks and guns coming into service, including Tigers and Panthers. Since the ISU-152's gun was mounted in a casemate, aiming it was awkward, and had to be done by repositioning the entire vehicle using the tracks. Therefore, it was used as mobile artillery to support more mobile infantry and armor attacks. It continued service into the 1970s and was used in several campaigns and countries.
The T-84 is a Ukrainian main battle tank (MBT), based on the Soviet T-80 MBT introduced in 1976, specifically the diesel engine version: T-80UD. The T-84 was first built in 1994 and entered service in the Ukrainian Armed Forces in 1999. Its high-performance opposed-piston engine makes it a fast tank, comparable to other modern MBTs with a power-to-weight ratio of about 26 horsepower per tonne.
The Type 59 main battle tank is a Chinese-produced version of the Soviet T-54A tank, an early model of the ubiquitous T-54/55 series. The first vehicles were produced in 1958 and it was accepted into service in 1959, with serial production beginning in 1963. Over 9,500 of the tanks were produced by the time production ended in 1985 with approximately 5,500 serving with the Chinese armed forces. The tank formed the backbone of the Chinese People's Liberation Army armoured units until the early 2000s, with an estimated 5,000 of the later Type 59-I and Type 59-II variants in service in 2002.
The Type 69 and Type 79 are Chinese first generation main battle tanks. Both were developments of the Type 59 medium tank with technologies derived from the T-62. They were the first indigenously developed main battle tanks by China, although also classified as medium tanks while in development and service. Their lineage from the T-54A can be seen through the distinct gap between the first and second road wheels. Other improvements included a new engine, ballistic computers, and laser rangefinders. The more advanced Type 79 variant was equipped with a 105 mm rifled gun which was also found on the Type 80 tank.
The FV4201 Chieftain was the main battle tank (MBT) of the United Kingdom from the 1960s into 1990s. When introduced, it was among the most heavily armed MBTs of the era, mounting a 120 mm Royal Ordnance L11 gun, the equal of the much larger specialist heavy tanks then in service. It also was among the most heavily armoured, with up to 195 mm (7.7 in) that was highly sloped to offer 388 mm (15.3 in) thickness along the line of sight.
The Type 99 or ZTZ-99 is a Chinese third generation main battle tank (MBT). The vehicle was a replacement for the aging Type 88 introduced in the late 1980s. The Type 99 MBT was China's first mass-produced third-generation main battle tank. Combining modular composite armour and tandem-charge defeating ERA, 125 mm smoothbore gun with ATGM-capability, high mobility, digital systems and optics, the Type 99 represents a shift towards rapid modernization by the PLA.
The Black Eagle tank or Object 640 was a presumed prototype main battle tank based upon the T-80U, developed by the KBTM design bureau of Omsktransmash in the late 1990s for the Russian Federation. The Black Eagle was cancelled, with all production and development halted in 2009.
The AMX-10P is a French amphibious infantry fighting vehicle. It was developed from 1965 onwards to replace the AMX-VCI in the French Army. It served with the French Army from its introduction in 1973 until its retirement in 2015, when it was fully replaced by the VBCI.
The T-44 was a medium tank developed and produced near the end of World War II by the Soviet Union. It was the successor to the T-34, offering an improved ride and cross-country performance, along with much greater armor. Designed to be equipped with an 85 mm main gun, by the time it was fully tested the T-34 had also moved to this weapon. Both tanks offered similar performance, so introducing the T-44 was not considered as important as increasing T-34 production. Fewer than 2,000 T-44s were built, compared to about 58,000 T-34s. Although the T-44 was available by the end of the war, it was not used in any battle. It was 1 ton lighter than the T-34-85 and slightly faster. The T-44 was heavily influential on the design of the T-54/55 Medium tank, most prominently lower hull and turret profiles. Also notable was the T-44-100, a 100mm D-10T-armed prototype, which would be the same 100mm gun mounted on the T-54/55, bar some minor changes.
The D-10 is a Soviet 100 mm tank gun developed in late World War II. It originally equipped the SU-100 tank destroyers and was later selected for the T-55 tank, equipping these as late as 1979. On the T-55 the D-10 continues to be in active service in many countries.
The AMX-40 was a French main battle tank developed by GIAT during the latter stages of the Cold War as an export tank to replace the earlier AMX-32. Designed to be an inexpensive tank orientated towards militaries with smaller defence budgets, the AMX-40 featured a lightly armoured hull and good mobility reminiscent of previous French MBTs with a powerful 120 mm cannon. It however failed to attract interest and sales, rendering the project a failure, being discontinued in 1990.
The Uralmash-1 (Уралмаш-1) was a Soviet prototype self-propelled gun developed during World War II. It was a turretless, tracked armoured fighting vehicle designed by the Yekaterinburg-based Uralmash design bureau (UZTM) between autumn 1944 and spring 1945. It used the chassis of the T-44 medium tank and was intended to replace the SU-100 which itself had only entered service with the Red Army in late 1944. Two prototypes of the Uralmash-1 with different armament were built in early 1945, one with the 100 mm D-10 tank gun, the other with the 122 mm D-25S tank gun. While mass production was initially recommended, the end of the war with Germany in May 1945 eventually caused the project to be cancelled due to lack of necessity. If the Uralmash-1 had entered service, the 100 mm variant would have been designated SU-101 (СУ-101) while the 122 mm variant would have been designated SU-102 (СУ-102), in accordance with Soviet military nomenclature, where the "SU"-label stood for Samokhodnaya Ustanovka, or self-propelled gun.

The IS-3 is a Soviet heavy tank developed in late 1944. Its semi-hemispherical cast turret became the hallmark of post-war Soviet tanks. Its pike nose design would also be mirrored by other tanks of the IS tank family such as the IS-7 and T-10. Produced too late to see combat in World War II, the IS-3 participated in the Berlin Victory Parade of 1945, the Soviet invasion of Hungary, the Six-Day War, Yom Kippur War, and one was used during the early stages of the Russo-Ukrainian War.
The IS-2 is a Soviet heavy tank, the second of the IS tank series named after the Soviet leader Joseph Stalin. It was developed and saw combat during World War II and saw service in other Soviet allied countries after the war.
