T-80 - ...МОДИФИКАЦИИ

Command tanks with additional radio equipment have K added to their designation for komandirskiy ("command"), for example, T-80BK is the command version of the T-80B. Versions with reactive armour have V added, for vzryvnoy ("explosive"), for example T-80BV. Less-expensive versions without missile capability have a figure 1 added, as T-80B1.
Ob'yekt 219 SP1
The prototype designed by Nikolay Popov was constructed in 1969 by Leningrad Kirov Plant (LKZ) and designated Object 219 SP1. It was essentially the T-64T powered by a GTD-1000T multi-fuel gas turbine engine producing up to 1,000 hp (746 kW). During the trials it became clear that the increased weight and dynamic characteristics required a complete redesign of the vehicle's suspension.
Ob'yekt 219 SP2
The second prototype, designated Object 219 SP2, received bigger drive sprockets and return rollers. The number of road wheels was increased from five to six. The construction of the turret was altered to use the same compartment, 125 mm 2A46 tank gun, autoloader and placement of ammunition as the T-64A. Some additional equipment was borrowed from the T-64A. The LKZ plant built a series of prototypes based on Object 219 SP2. In 1976 it became the T-80.
T-80 (Ob'yekt 219) (1976)
First production model. The T-80 has some features of both the T-64 and T-72, and other features unique to itself. In general, the offensive capabilities of the T-80 are similar to the T-64A, but it is faster thanks to the GTD-1000T 1,000 hp (746 kW) multi-fuel gas turbine engine. Visual keys are large, die-cast, irregularly spaced, ribbed, rubber-tired road wheels with three support rollers, a self-entrenching blade on the lower glacis, a Luna searchlight in the same position as the T-64. Significant differences are a coincidence rangefinder, and probable enhanced armor on the glacis (an upper glacis of steel layers enclosing fiberglass layers and a cast steel turret enclosing nonmetallic materials). Unlike the later models, the early T-80 had V-shaped splash plate on glacis plate. Due to its armour being obsolete, only a few hundred were built between 1976 and 1978 before the production switched to the T-80B. Some T-80s were later upgraded to B level.
T-80M-1 - T-80 with an Arena countermeasures array fitted to rear of the turret's roof. It also has an armour belt around turret.
T-80B (Ob'yekt 219R) (1978)
This first major redesign features a modified turret with new composite K ceramic armor providing better protection against APFSDS kinetic energy penetrators. The protection level of the turret increased from 410 mm of steel to 500 mm of steel. It also includes 1A33 fire control system, 9K112-2 system which allows firing 9M112 "Kobra" (NATO code: AT-8 Songster) ATGM using the tank's barrel. The missile control box is mounted in front of the cupola and has angled support. The ATGM may be launched while moving slowly and can be auto-loaded with the two-halves mated during ramming but the stub charge is manually loaded. Unlike T-80, T-80B does not have a splash plate on glacis plate.
T-80B obr.1980g. - T-80B with a new 1,100 hp (820 kW) GTD-1000TF gas turbine engine.
T-80BK (Ob'yekt 660) - T-80B command tank equipped with additional R-130 radio, TNA navigation set, a 2nd whip antenna and a telescopic mast. It does not have the 9K112-2 system.
T-80BV (Ob'yekt 219RV) (1985)
T-80B with Kontakt-1 explosive reactive armour. The smoke grenade launchers were moved from either side of the main armament back to the either side of the turret and positioned between the turret side and the ERA panels. On the turret of the T-80BV, the panels are joined to form a shallow chevron shape. ERA is also fitted to the forward part of the turret roof to provide protection against attacks from above. While the ERA provides a high degree of protection against ATGM of its time which relied on a HEAT warhead to penetrate armor over the frontal arc, it does not provide any added protection against APDS or APFSDS. Vehicles which were built first for sometime lacked the ERA because of supply problems. Some T-80BV tanks have been equipped with dust flap under glacis plate and some of them were equipped with single line of ERA along top of hull side. A late production version had a new turret similar to the T-80U but with Kontakt-1 ERA.
T-80BVK - as per T-80BK but with ERA. First models were just T-80BK tanks with ERA. Later models were T-80BV tanks with additional communications equipment and an antenna.
T-80BVM (2017)
Up to 300 units, new "Relikt" ERA, PNM Sosna-U gunner sight (as in T-90 and T-72B3), improved 2A46M-4 125 mm gun, upgraded gas turbine engine, and upgrade of various other systems. Currently being delivered.
T-80A (Ob'yekt 219A) (1982)
A further development of T-80B. It was developed in late 1970s and first model was produced in 1982. It was an attempt to provide the T-80B tank with an improved armour and firepower. It uses 1,200 hp (895 kW) GTD-1000M gas turbine engine. It has the 9K119 system which allows it to fire 9M119M Invar (AT-11B Sniper) ATGM using the tank's barrel. It also had several pintle mounts for the NSVT heavy machine gun and other improvements. The ammo load for 125 mm smoothbore tank gun was increased considerably when comparing it to the one of T-80B (T-80B - 38 rounds, T-80A - 45 rounds). It has some features of the future T-80U including the new turret with stronger armour and equipped with a new fire control system with the 1G46 gunner's sight. However, because of all those improvements T-80A is 2.8 tonnes heavier than the T-80B. It never left the prototype stage and was further developed as T-80U.
T-80A obr.1984 - T-80A with Kontakt-1 explosive reactive armour. The model with Kontakt-1 is sometimes called T-80AV. The main external difference from the T-80BV is the lack of Kobra missile guidance box in front of the commanders cupola.
T-80AK - Command variant of T-80A.
T-80AK obr.1984 - T-80A with Kontakt-1 explosive reactive armour. The model with Kontakt-1 is sometimes called T-80AKV.
T-80U (Ob'yekt 219AS) (1986)
("U" for uluchsheniye, meaning "improvement") A further development of T-80A. This version has a new 1,100 hp (820 kW) GTD-1000F multi-fuel gas turbine engine as well as 1A46 fire control system and a new turret. T-80U also received a different engine decking. 9K112-2 system was replaced with newer 9K120 system which allows firing 9M119 Svir (AT-11 Sniper) and 9M119M Refleks (AT-11B Sniper) ATGM. Also the 12.7 mm NSVT heavy machine gun received the ability to be fired from within the turret with a use of a remote-control which work in a similar manner to the one in T-64. Infra-red searchlight mounted on the commander's cupola is replaced with an image intensification channel. There's a laser designation system mounted on the tank's roof forward of the tank's commander cupola, it projects a modulated beam. The system is protected by a rectangular armored box cover. Like all of the previous T-80 models, the T-80U has full length rubber side skirts protecting the sides but those above the first three road wheels are armored and are provided with lifting handles. There are also rubber elements fitted beneath the front glacis which provide additional protection against mines with tilt-rod fuses and HEAT warheads. The forward skirt elements are armored and a radiation absorption liner coat is mounted on the inside and on the outside of armour. The turret roof between the commander's and gunner's hatches has been provided with additional protection against attack from above. Driver's protection, particularly against mine explosions, is enhanced by suspending the driver's seat from the hull roof. Two clusters of four 81 mm 902B Tucha electrically operated smoke dischargers are mounted on either side of the turret. The new turret also has an improved frontal armor package with Kontakt-5 explosive reactive armour which defeats APFSDS. Early production version of T-80U still used Kontakt-1 ERA. A special camouflage paint distorts the tank's appearance in the visible and IR wavebands. GTA-18A Auxiliary Power Unit is used when the engine is off. Late production version had a more powerful GTD-1250D multi-fuel gas turbine engine and the "Brod-M" snorkel.
T-80U obr.1992 - T-80U with an improved 1,250 hp (930 kW) GTD-1250 multi-fuel gas turbine engine.
T-80UK - Command version, equipped with additional R-163-50K and R-163-U radios, TNA-4 land navigation system, TShU-1-7 Shtora countermeasures system, electronic fuze-setting device that permits use of "Ainet" shrapnel round, a meteorological sensor, laser warning receivers, "Agava-2" thermal sight which provides a 2,600-meter night acquisition range, fire control and APU. Became the main Russian export tank in the 1990s. It can be easily recognized by EO boxes on the front of turret on either side of the main armament and multiple radio antennas.
T-80UE (1999) - Export version of the T-80U with some of the equipment from the T-80UK (including the TShU-1-7 Shtora electro-optical countermeasures system). Unlike the T-80U it does not have the anti-aircraft heavy machine gun mounted on the commander's cupola, instead it has pintle mounts at the four corners of the turret allowing its position to be switched.
T-80UM (Object 219AS-M) - Modern version of T-80U. Modernization of 1995. Russian version with a new weapon system for the 9M119M Refleks (AT-11B Sniper) ATGM, new thermal imaging sight "Agava-M1" (optionally "Agava-2" or "Buran-R") because of which the L-4 "Luna" IR has been removed.
