Description

The T-72B MBT (Main Battle Tank) is developed from the Russian main battle tank T-72A. It was entered into service with the Russian army in 1984. Its turret has a new armor package that provides a much higher degree of protection than any previous model of the T-72 MBT. In addition, the glacis plate is provided with 20 mm of appliqué armor. The layout of the T-72B is identical to the T-72A but differs in the addition of ERA cassettes that are added wherever possible to the turret, glacis, and hull sides. The T-72B can be distinguished from earlier T-72s by the additional ERA and the additional thickness at the front of the turret.

Variants

T-72A Second Russian main variant of the T-72.

T-72B1 In 1986, a limited production variant without an ATGM launch capability. Some do not have ERA.

T-72BK The Commander's variant with additional radios.

T-72BM Russian T-72B upgrade with 2nd gen ERA. The system is fielded, available for export, and upgraded. Tier 2 and some Tier 3 tanks can challenge US forces under favorable conditions when using modern ammunition and employed by well-trained units with sound tactics. A variety of upgrades are available for the T-72B. They include protection upgrades, such as improved ERA, APS, defensive aids suites with IR jammers, plate armor, welded turret, and grill armor around tracks and grill. Mobility upgrades include a new power train, improved steering, improved mine plows, and rollers, and an electronic mine spoofing system. Fire control system upgrades include new sights, guns, ammunition, and improved stabilization. With the expanding number of upgrades offered by former Warsaw Pact, Asian, Israeli, and other firms, most T-72-type tanks have some level of upgrade from the basic T-72 MBT. The more affordable upgrade approach for most countries is to execute specific upgrades during maintenance work. But this approach may result in only partially modernized tanks at any one point in the life of the vehicle, and which are not as modern as more recent competitors. An alternative is to produce modernized tanks in small numbers, resulting in high per-unit production costs.

T-72BU Upgrade variant with the fire control system from the T-80U as well as well as a variety of other changes.

T-72BU renamed T-90 With the limited market for new tanks, the world tank industry has developed upgrades and whole vehicle upgrade packages to tap into the market. Older T-72 tanks can be brought up to the T-72B standard. Some approach the T-90 standard. Most T-72-type tanks fielded reflect some level of upgrade. Upgrade options are expanding from former Warsaw Pact, Asian, Israeli, and other international firms.

T-72S / Shilden Russian export T-72A upgraded to the T-72B standard. Although visually similar to T-72B, it has slightly less chassis and turret protection. Former Warsaw Pact countries such as Slovakia and Middle Eastern countries like Iran have upgraded their tanks to the T-72S standard.

M-84AB1 Yugoslav upgrade to the M-84, bringing it close to the T-90, and the latest T-72B improved tanks.

M-95 Degman Croatian M-84 upgrade with box composite armor, ERA, 1200hp, and thermal FCS. An export upgrade conversion, AKA M-84D, is offered for Kuwaiti M-84A tanks.

PT-91 Polish upgrade tanks with ERA, Drawa improved FCS, Savan-5 thermal sight, improved gun stabilization, and countermeasures.

PT-91M Has a 1000hp engine, new guns and FCS, armor changes, and other improvements. PT-91M exported to Singapore. PT-91P is designed for export to Peru.

T-72M1 Demonstrator with 2nd generation ERA and other upgrades were displayed at military shows.

T-72M1M Includes 3rd generation Relikt ERA and optional Arena Active Protection System (APS). Alternative designations: Rogata and SMT M1988. It is almost the same as the T-72S (Export), except more ERA on the side skirts.

AJEYA MK 2 India is upgrading T-72A tanks close to a Bhishma (T-90S) standard.

Mine Clearing The KMT-5 mine clearing plow-roller set consists of two plows and two roller sections of three rollers each. This combination is attached to the front of a tank hull. Stretched between the roller sections is a "dogbone" assembly which consists of a light chain and small roller weights. Using a dragging motion, the "dogbone" covers the exposed area between tank tracks, thus exploding tilt-rod mines. The flexibility of the KMT-5 allows the use of plows or rollers depending on the terrain, type of soil and fuse types encountered. The KMT-5 can be used with the T-54/55, T-62, T-64, and T-72 tanks. The system can withstand approximately nine explosions that have a capacity of five to six kg. It is fitted with a quick-release disconnect unit to allow the tank driver to release the set rapidly. One other capability is that the KMT-5 may be used during night operation, using the luminous lane-marking device (PSK equipment) which marks the clear lane at night with a luminous substance.

Note #1 The T-72B can be distinguished from earlier T-72s by the additional ERA and the additional thickness at the front of the turret.

Note #2 The base protection of the T-72B is the same as the T-72A, however the vehicle is upgraded with considerable amounts of additional composite armor.

Note #3 The additional added armor cassettes reduce penetration by as much as 95%.
