T-90ms: a big step forward
British kazhdomesyachny magazine IHS Jane’s International Defence Review published an article by Christopher F. Foss on a brand new Russian tank T-90ms. Creator — the largest zabugorny expert on armored vehicles and armament of the Army.

He not only browser such recognizable in the midst of military professionals of magazines like IHS Jane’s International Defence Review and IHS Jane’s Defence Weekly, and the editor of a noble yearly directory Jane’s Armour and Artillery («armor and artillery»), His outlook on T-90ms, certainly deserves attention.

With its main battle tank, which owns Oversize EFFICIENCY IN URBAN criteria Our homeland is aimed at EXPORT MARKETS

Christopher F. Foss

Russian Uralvagonzavod has developed an improved version of the main battle tank (MBT) T-90S, which is currently being aimed at the export market. Compared with baseline model newcomer modification popular as T-90ms, different improvement of all 3 components of the triad armored vehicle: firepower, mobility and protection, designed to improve the overall efficiency of its urban criteria. What elements or T-90ms very similar to elements of the tank Leopard-2 PSO firm Krauss-Maffei Wegmann, created for peacekeeping operations.

In the Russian time Our homeland disposed of 4 tank plants. Now she has only one — «Scientific and Production Company» Uralvagonzavod «in Nizhny Tagil. Besides promoting MBT T-90ms on the world market the company continues to sell the previous model T-90S tank commander T-90SK also fighting vehicle fire support «Terminator.» The latter was developed in accordance with the requirements of the Russian army, but was among the programs, suspended in 2010 Game «terminator» was sold to Kazakhstan, where the machine for the first time appeared in the parade in 2011

T-90ms armed upgraded 125-mm smoothbore gun 2A46M-4 (in fact refers to the gun 2A46M-5 — approx. Edition), which is claimed to provide a significantly higher accuracy compared with the previous models, and the dispersion of the shells has decreased by least, 15%. Unlike models 2A46M its trunk chrome that provides overcharge his vitality. He also resettled ejector shroud thermal protector and accounting system thermal meander of the gun barrel, which allows the gunner to inspect the line of sight through the bore without departing from the tank.

As with all family tanks T-72 autoloader placed below the turret and provides loading of the gun shell, and then charge with partly burned down sleeve, from which a shot can only pan. In ammunition includes 22 ready to use the shot (projectile and charge) plus 18 shots available in reserve. Previously, all spare shots were placed in the tank hull, but T-90ms most of them moved to the aft part of the tower, in what is now expelling installed panels on the roof. Other 125-mm ammunition stored in the fighting compartment, but in a separate section to increase crew survivability.
The actual composition of ammunition 125mm gun will depend on combat tasks performed by tank. The tank can carry a full range of everyday shooting ammunition, including armor-piercing discarding sabot projectile feathered (BOPS), cumulative projectile (COP) and high-explosive/fragmentation (CFC). He can also shoot the guided missile laser-guided 9M119M at a range of 100 to 5000 m Projectile 9M119M resettled tandem HEAT warhead and is capable of hitting targets outside the firing range of the main armament. From the gunner requires detain crosshair tools and associated illumination laser spot on the target to the rocket hit the target, which can take up to 15 seconds at maximum range.

Coupled with the gun 7.62-mm machine gun PKTM (6P7K) is set to the right of the main armament and ammunition has a standard 2000 rounds.
Installed on the roof of the tower 12.7-mm machine gun 6P7K (in fact, this gun is 7.62 mm, but in its place by the customer can be installed mnogokaliberny anti-aircraft gun — approx. Edition) in remotely controlled weapon stations. It can rotate 316 degrees in azimuth and range from -10 to +45 degrees in elevation to hit targets in urban labyrinths. Food machine gun carried by 2-magazine capacity of 400 rounds each, and from the probable shooting on the move.

T-90ms resettled computerized fire control system (FCS), which allegedly allows the crew to hit stationary and moving targets, including when the tank itself is in motion, with the highest probability of hitting the target with the first shot in virtually all weather criteria . This MSA contains a digital ballistic computer and a set of sensors, including sensor criterion shooting, mounted on the roof, and automatic target tracking. There is also an emergency sight, associated with the main armament and located in front of the main gunner’s sight.

On the roof of the tower there is a separate stabilized commander’s panoramic sight, having a television and thermal channels, a laser rangefinder and that allows to implement the principle of «hunter-shooter.»

The commander also has day periscopes for radial observation. Cover flap tower can be closed or partially tilted backwards, like an umbrella, raised.

Place gunner Resettled stabilized TV / teplovovizionnym sighting system which includes a laser rangefinder with maximum range of 7500 m and the sight missile guidance 9M119M.

Russian tanks usual drawback was the lack of thermal sights, because T-90ms in standard configuration is a big step forward, and significantly improved situational awareness tank makes applicable for use in urban criteria. For example, apart from the sights and periscopes, four cameras provide almost radial charts, transferring images on monitors commander and gunner. Any camera has a field of view of 95 degrees in azimuth and 40 degrees elevation.

As the power plant is used forced a 12-cylinder diesel engine in the power-92S2F 1130 hp coupled with the automatic transmission. Through this 48-ton tank is equipped with a power density of 22.9 ps / m, sufficient for the traffic on the highway at a speed of 60 km / h

T-90cm able to overcome a ford deep 1,2 m without preparation and up to 5 m — with special equipment.

IMPROVED BOOK

In the basic model T-90 was used absolutely welded housing made of metal armor with improved frontal armor plate, and the tower was absolutely cast and had a built-in armor. Last version of the T-90ms has the hull and turret with improved armor that provides overcharge protection from ammunition hitting the top.

This superior set of armor includes not only the protection of dynamic modules (RS), and passive armor elements in modules that in case of damage can be rapidly changed.

Rear hull and turret equipped bars, providing more effective protection against rocket-propelled grenades, and in the fighting compartment are also provided-proof screens to protect the crew from the secondary fragments.

Active protection of ammunition semi-active laser guidance system provides automatic smoke-screens. This system consists of multiple laser sensors are located so as to provide a radial scan location. Upon detection of laser hazards, the crew is alerted by visual and audio means, and in the direction of danger put a gun spray Zahav. In addition, the tower can be rotated in the direction of the machine with the following danger actuation 81mm smoke grenade launchers mounted on either side of the tower.

T-90ms is also equipped with electrical protection system capable allegedly neutralize anti-tank mines, kitted electric detonators.

This also installed armored vehicle combat control and navigation system, which allegedly can be integrated directly to division.

Outside on the rear left side of the tank’s hull mounted auxiliary diesel-electric installation, providing the main function of the T-90ms, when the main engine is shut down to save fuel.

T-90ms is also equipped with equipment for self-entrenching installed on the front armor plate, which can be used, and to overcome obstacles. Standard equipment auxiliary equipment includes fire fighting system, NBC protection system and a communication system crew.
