The T-80 is a main battle tank that was built in Russia after first being designed and developed in the former Soviet Union. This impressive tank, which deviated from conventional power sources, was the first in production to be propelled exclusively by a turbine engine when it was first launched in 1976.
Built on the T-64’s underpinnings, the T-80 skillfully combined features from the subsequent T-72, displaying a well-balanced fusion of innovations. Engineer Nikolay Popov from the USSR was the mastermind behind its design. In 2023, Uralvagonzavod’s CEO unexpectedly announced that production of the T-80U would resume, having stopped in 2001. Outside of Russia, the T-80 and its variations were operational in countries like Uzbekistan, South Korea, Belarus, Cyprus, Egypt, Kazakhstan, and Pakistan. The T-84, which Ukraine developed from the T-80UD, is noteworthy because it guaranteed Ukraine’s survival in international competition.
The formidable T-80 main combat tank from the Soviet era is available in two variants: the T-80B and the improved T-80U, both with unique specifications. At 42.5 tonnes in mass, the T-80B is 9.9 metres long (gun forward) and 7.4 metres wide (hull), with a height of 2.202 metres. Its breadth is 3.4 metres. With hull protection of 440–450 mm against APFSDS and 500–575 mm against HEAT, and turret protection of 500 mm against APFSDS and 650 mm against HEAT, its three-man crew functions within an armour configuration.
Outfitted with four 9M112 Kobra ATGMs and a 125 mm 2A46-2 smoothbore gun with 36 rounds, it is ready for combat. Conversely, the 46-ton T-80U has a slightly shorter gun forward length of 9.654 metres and a hull length of 7 metres, a larger body measuring 3.603 metres, and a comparable height of 2.202 metres. Improved armour offers a remarkable 1,320 mm against HEAT and 780 mm against APFSDS, with Kontakt-5 protecting the turret and hull.
The primary armament of the T-80U consists of six 9M119 Refleks ATGMs and a 125 mm 2A46M-1 cannon with 45 rounds. Both variants have supplementary weaponry, which consists of a 7.62 mm coaxial PKT machine gun and an additional 12.7 mm PKT anti-aircraft machine gun, NSVT, or DShK. The SG-1000 gas turbine engine, which has a 1,000 horsepower output and a 23.5 horsepower per tonne power-to-weight ratio, powers the T-80B.
The T-80U, on the other hand, has an enhanced power-to-weight ratio of 27.2 horsepower per tonne and a 1,250 horsepower GTD-1250 turbine. The T-80U has four forward gears and one reverse, while the T-80B has a manual gearbox with five forward gears and one reverse. The gearbox systems are different. With a ground clearance of 0.38 metres for the T-80B and 0.446 metres for the T-80U, the tanks are suspended using a torsion bar system. The internal fuel capacities of both tanks are 1,100 litres, while the exterior fuel capacity is 740 litres. With no external tanks, the T-80B can operate up to 335 km (208 mi) and 415 km (258 mi) on roads. The top speed achieved by the T-80U is 80 km/h (50 mph) over cross-country terrain, and 48 km/h (30 mph). Together with cutting-edge armaments, strong armour, and remarkable agility, these T-80 variations are powerful military assets.
Since the first production model was introduced in 1978, the T-80 class of tanks has undergone considerable evolutionary alterations. With its composite K ceramic armour and increased protection, the T-80B represented a significant redesign. While the T-80BV debuted first-generation explosive reactive armour (ERA), the T-80BK functioned as a command variant. When the T-80U was seen in 1989, it had better frontal armour, a laser-guided anti-tank missile, and a more powerful gas turbine engine.
A 1000-horsepower diesel engine took the place of the turbine engine in the Ukrainian-built T-80UD. Improved thermal sights were fitted to the T-80UM, while integrated defensive systems were part of the T-80UM1 “Bars” prototype. The “Black Eagle” or T-80UM2 displayed an autoloader and a new turret. French ALIS thermal sight, an active protection system, and a welded turret were features of the T-84, a new Ukrainian improvement of the T-80UD.
The most recent upgrade, the T-80BVM, had updated auto-loader technology, Sosna-U gunner sight, and “Relikt” explosive reactive armour. As a reflection of continuing advancements in armoured warfare, Russian tank manufacturer UVZ was awarded an additional order in 2020 to supply the T-80BVM with cutting-edge armaments from the T-14 “Armata” tanks. The Defence Ministry has placed an initial order for 50 units, with the option to increase the quantity if the outcome meets expectations.
A veteran of numerous battles, notably the First and Second Chechen Wars and the Russo-Georgian War, the T-80 is a powerful tank with long combat experience. Russia used the T-80 in the Chechen conflict, where it was put to use in the region’s difficult terrain and urban fighting. Delivering armoured assistance to Russian forces in the ongoing struggle in the North Caucasus, the T-80 continued its service in the Second Chechen War.
Specifically in the South Ossetia region, Russian military personnel used the T-80 during the brief war with Georgia. Throughout the war, the tank was involved in several ground missions. South Korea and Ukraine are two nations that have utilised the T-80 tank, despite it not being shipped as frequently as some other tank variants.
A weapon of war with military prowess and real-world obstacles, the T-80 has been criticised for its high production cost, complex maintenance requirements, and limited export potential due to its reliance on advanced technologies. However, it nonetheless endures as a dependable fixture in the military forces of several countries, providing a sobering reminder of the technological superiority and tactical heritage of the Soviet era.
