T-90AM: Latest Avatar Of The T-90 MBT






T-90%2527s+Latest+Avatar-11.jpg

























‘Der aye, durust aye’ (better late than never) will probably be the best way to welcome the emergence of the 50-tonne T-90AM—the latest member of the T-90 family of main battle tanks (MBT). In a nutshell, the T-90AM appears to have overcome all the previous design/performance deficiencies associated with the earlier T-90 variants (the T-90S and T-90M), and also with the T-72, from whose design the T-90’s design has evolved. Interestingly, India has had a huge though as yet unacknowledged role to play with the T-90AM’s R & D process. In order to delve deeper into this issue, we will have to take a walk down memory lane back to the late 1970s and early 1980s when the Indian Army was evaluating its options for a future main battle tank (FMBT) of imported origin to complement the indigenously designed Arjun MBT—which then was still on the drawing boards.


By the late 1970s, Indian Army HQ had decided to acquire new-generation replacements for its UK-origin fleet of Royal Ordnance Factories-built Centurion and Vickers-built Vijayanta Mk1 MBTs and consequently, paper evaluations concerning the firepower and mobility characteristics of the two principal contenders being offered for full in-country production—AMX-40 developed by GIAT Industries of France, and the Chieftain 800 (which later evolved into the Challenger 1 from Royal Ordnance Factories (then owned by British Aerospace PLC)—were conducted by the Indian Army. Between these two contenders, the Army had by early 1980 zeroed in on the 43-tonne AMX-40 MBT, which was still on the drawing boards and was meant to be powered by a 1,100hp Poyaud V12X 12-cylinder diesel engine coupled with a LSG-3000 automatic power shift transmission built by RENK Aktiengesellschaft of Germany (offering a power-to-weight ratio of 25.6hp/tonne, and armed with a 120mm smoothbore cannon. However, things didn’t go according to the Army’s well-conceived plans, since, after coming back to power, the then Indian Prime Minister Mrs Indira Gandhi took the political decision to acquire new-build MBTs from the USSR, following which the Soviet Union’s Ministry of Foreign Economic Relations (which after 1991 morphed into Oboronexport, then Rosoboronservice and ultimately Rosoboronexport State Corp) made a formal offer to India’s Ministry of Defence (MoD) for supplying the 37-tonne T-72M Ob'yekt 172M-E4 MBT off-the-shelf, and according an approval for licenced-production of the 41.5-tonne T-72M-1982 Ob'yekt 172M-E6 to the MoD-owned Heavy Vehicles Factory (HVF) in Avadi. By early 1981, two T-72Ms--powered by a 780hp diesel engine, armed with 125mm 2A46M smoothbore gun and offering a power-to-weight ratio of 20hp/tonne, were subjected to an exhaustive series of in-country firepower and mobility trials by the Army, while copies of the T-72M’s operating and maintenance manuals supplied by the Soviets (who in those days were totally aghast when shown marketing brochures of competing MBTs of Western origin and were asked why such types of materials were unavailable from the USSR) were subjected to intense academic and operational scrutiny for a 90-day period.


Immediately later, a delegation of ‘experts’ comprising members of the MBT’s design bureau-- Kartsev-Venediktov; the MBT’s manufacturer--Uralvagonzavod Factory located in Nizhny Tagil; and officials from the Soviet Defence Ministry’s Land Forces Armaments Directorate, all converged at the Indian Army HQ, where extensive deliberations on and analysis of the T-72M’s in-country firepower and mobility trials were conducted by both sides for at least a week. Following all this, it ultimately emerged that while the T-72M possessed excellent and hassle-free mobility characteristics, its firepower capabilities were clearly a full generation behind that of the AMX-40. The Army, which had all along wanted to acquire a MBT incorporating hit-survivability design features (something that the home-grown Arjun Mk1 MBT’s design strongly signifies), now found to its utter horror that basically, with the exception of the T-55, the overall Soviet approach to MBT design in the post-World War II era was found to be flawed on two major counts: namely, the gamble on not being hit rather than on surviving hits, and the refusal to perceive survivability of the tank crew as a quite distinct issue from survivability of the vehicle, with the former having priority over the latter. The combination of these two shortcomings produced design solutions such as the T-72M’s carousel autoloader and ammunition reserve being accommodated on the turret floor. This indeed allowed for a very compact configuration and ensured that the ammunition is less likely to take a direct hit—but it also entailed a very high risk of ignition or sympathetic detonation should the fighting compartment be penetrated, in which case there went the MBT and the crew with it. When confronted with such ‘hard facts’ along with the Army’s criticisms about the lack of even a ‘decent’ hunter-killer fire-control system (when compared to the likes on board the AMX-40), members of the Soviet delegation were clearly red-faced and a depressed lot, and it took several bottles of vodka during and after dinner-time to come out with the truth: according to the MBT’s designers, the performance characteristics of all weapons produced in the USSR were dictated purely by the warfighting doctrine of the country’s armed forces. Hence, weapons like the T-72M were meant for usage only by follow-on echelon formations of the Red Army, while the all-critical breakout forces then stationed throughout the East European member-states of the Warsaw Pact were equipped with state-of-the-art MBTs like members of the 38-tonne T-64 and 42.5-tonne/46-tonne T-80 MBT families—designed by the Ukraine-based Morozov Design Bureau and series-produced at Malyshev in Kharkiv, Ukraine, and in Russia by both the Leningrad Kirov Plant and Omsk Transmash. In other words, while members of the T-64 and T-80 MBT families were the vanguard elements of the Red Army’s armoured juggernaut, those of the T-72 MBT were meant to be used merely for encirclement and envelopment of the enemy’s armoured formations.

Yet, despite all this, India’s Cabinet Committee on Political Affairs of the day decreed that the T-72M and T-721982 (powered by a Model V-84MS four-stroke 12-cylinder multi-fuel engine developing 840hp and offering a power-to-weight ratio of 18.8 hp/tone) would be the Army’s future MBTs, and a procurement contract for 2,418 T-72s was subsequently inked. Interestingly, while the first off-the-shelf shipments of T-72Ms began arriving by ship in Mumbai in mid-1982, in Lebanon the 105mm APFSDS rounds fired by Israeli Merkava Mk1 MBTs with 105mm rifled-bore guns routinely pierced the Syrian T-72M’s front glacis, went straight through the MBT and exited through the engine compartment, leaving a turretless hulk behind. Five years later, The Indian Army’s worst fears were realised when got a first-hand demonstration of the T-72M’s acute vulnerability in October 1987, after LTTE guerrillas exploded improvised explosive devices underneath two T-72Ms deployed with the Army’s 65 Armoured Regiment for Operation Pawan during the battle for Jaffna, which resulted in armour penetration and the ensuing catastrophic detonation of the MBT’s ammunition reserve (this being stored in a carousel autoloader on the turret’s floor), resulting in the turrets being blown off. Subsequent events in 1991 during Operation Desert Storm would convincingly highlight the T-72’s totally flawed design features. Despite such developments, the Army—starting in 1988 began inducting the HVF-built T-72M-1982s into service.

A year earlier (1987), however, the Indian Army—being acutely aware of the T-72M’s vulnerabilities, had decided to undertake Project Bison—an ambitious upgrade project in cooperation with Yugoslavia’s state-owned Yugoimport SDPR, under which all its T-72Ms would be fitted with a new rolled homogenous armour (RHA) package developed by the Ravne-based Slovenske Železarne and comprising high-hardness steel, tungsten, and plastic fillers with ceramic components, plus the SUV-M-84 digital fire-control system that incorporated a Hughes-built gunner’s sight that was stabilised in two axes and included a thermal imager and laser rangefinder. The gunner’s ballistics computer—developed by Banja Luka-based Rudi Cajevec—was designed to automatically download crosswind data, vehicle cant, azimuth tracking rate and range, while the gunner manually inputted the data for air pressure, air temperature, barrel wear, barrel droop and ammunition type. Also planned for retrofit was the 12-cylinder water-cooled V-46TK 1,000hp diesel engine, that would have given the T-72M a power-to-weight ratio of 24.10hp/tonne. A procurement contract was signed with Yugoimport SDPR in early 1989 and an advance down-payment was made as well, but by 1991, Project Bison had to be scrapped in its entirety as by then civil war had broken out in Yugoslavia, and the country was subjected to an UN-mandated universal arms export/import embargo.

Both the MoD and the Indian Army learnt valuable lessons from Project Bison, and almost a decade later, when it came to the planned procurement of 1,657 T-90s (to replace the 1,781 T-55 and T-72M MBTs in a phased manner), it was decided to adopt a product block developmental approach similar to what by then was being planned for the Indian Air Force’s Su-30MKI procurement exercise. Consequently, in February 2001, India bought its first batch of 310 47.5-tonne 47.5-tonne T-90S MBTs worth US$795 million, of which 124 were delivered off-the-shelf, 86 in semi-knocked down kits (for licenced-assembly by the MoD-owned HVF in Avadi), and 100 in completely-knocked down kits (all these MBTs were retrofitted with Saab’s IDAS radar/laser warning system and LEDS-150 active protection system, or APS, worth Rs25 billion between 2009 and 2011). This was followed by a follow-on contract, worth $800 million (or Rs175 million per unit), being inked on October 26, 2006, for another 330 T-90M MBTs that were to be built with locally-sourced raw materials and also come fitted with LEDS-150 APS. The third contract, worth $1.23 billion (which was inclusive of the R & D funds required for designing a customised version of the T-90—the 50-tonne T-90AM), was inked in December 2007 for 347 upgraded T-90Ms, which are now being licence-built by HVF. These T-90Ms each come with a THALES-built Catherine-FC thermal imager (operating in the 8-12 micron bandwidth and housed within the Peleng-built 1G-46 gunner’s sight), the commander’s panoramic sight (which houses the Matis-STD thermal imager that operates in the 3-5 micron bandwidth and which has also been selected for the Arjun Mk1 MBT’s panoramic sight), an automatic gearbox, an electro-hydraulic turret-drive-cum stabilisation system, and most importantly, has a 2A46M-5 Rapira smoothbore main gun barrel that also comes fitted with a muzzle reference system.

While all theenhancements featured on the T-90M will also be found on the T-90AM, the latter will, among other things, incorporate a totally new redesigned turret that will now house a remote-controlled weapon station, an independent commander’s panoramic sight and gunner’s sight, a rear-mounted ammunition stowage bustle and its autoloader (thereby doing away with the much-criticised carousel autoloader on the turret’s floor and enabling the stowage of single-unit FSAPDS rounds containing long-rod kinetic energy penetrators which the T-90S and T-90M cannot fire at the moment), and redesigned modular armour tiles. The hull-section, housing the driver’s and gunner’s compartments, will be equipped with a battlespace management terminal, fibre-optic gyro-based land navigation system, software-defined radio suite, health-and-usage management systems for on-board diagnosis of the MBT’s vectronics and automotive elements—all these being selected and furnished by the customer (in India’s case) to Uralvagonzavod for on-board fitment-cum-integration. Also to be furnished by India for integration is the active protection suite (APS), for which the LEDS-150 is competing with the Iron First APS (already installed on board the Arjun Mk2 MBT) from Israel Military Industries. Powerplant for the T-90AM will comprise a Chelyabinsk Tractor Plant-built 1,130hp V-92S2 diesel engine, while a 1kW AB-1-P28 auxiliary power unit will provide back-up electric power when the engine is idling. By today calculations, 670 T-99AMs could well be delivered to the Indian Army between 2013 and 2019.


This finally brings us to the issue of whether or not to upgrade the remaining 1,664 T-72s in successive tranches. Already, 692 T-72Ms have been upgraded thus far into the T-72 ‘Combat-Improved Ajeya’ standards, while a follow-on tranche of 700 T-72M1s (whose per unit procurement cost is Rs90 million) is due to be upgraded at a cost of Rs50 million per unit, for which there is an on-going competition between Russia’s Rosoboronexport State Corp, ELBIT Systems of Israel, and the Raytheon/Larsen & Toubro combine, with work scheduled for completion by 2018). One interesting view prevailing within the Army HQ’s Directorate of Mechanised Forces calls for scrapping the planned T-72 upgrades altogether and instead procuring up to 900 T-90AMs and up to 400 Arjun Mk2s (each costing Rs380 million or $8.2 million) before 2020. This view also calls for re-engineering the hulls of the existing 1,100 T-72Ms and 1,318 T-72M-1982s to accommodate a family of turrets housing not only missile-launchers of the Akash E-SHORADS and their Rajendra L-band PESA target engagement radars and battery command-and-control centres (62 T-72M hulls have already been re-engineered for this purpose), but also air-defence artillery guns and their fire-control systems like the Skyranger from Rheinmetall Defence, a turret containing anti-armour guided-missiles like up to eight Kornet-EM in ready-to-fire configuration along with a 30mm rapid-fire cannon and 30mm automatic grenade launchers—all remotely-operated, MLC-70 bridge layers (like the BLT-72), equipment required by armoured recovery vehicles for the T-90 family of MBTs, and counter-mine flails.—Prasun K.

.
i hope we replace t 72 with T 90 AM.

we should buy at least 510 T 90 AM MBTs.
 
.
the good news is that we can upgrade to 50+ ton class really easily.
 
.
i hope this shows how these Russians have always exploited our defense needs and hope fully our croupt politicians will keep on drinking more vodka and help them with that and not miss our army hierarchy
 
.
^^ well we can turn t 90s into T 90 AM.

but it requires removing turret and fitting newer one.

hence we should not upgrade remaining T 72s and should go for T 90 AM
 
.
why not to induct more arjuns may be half the no. of t 72 but dear friends they will be more than twice as effective leave and come over this russian junk...... really these all tanks are junk when compared to modern tanks like merkava or leopard or even the luckrack ............
 
.
Wow :blink: The turret looks more...Westernized :blink:

And it's 50 tonnes!
 
. .
Lets hope DASS-GUPTA is right this time...
 
.
50 ton is a good weight

what about the engine?
does the engine is still the 1200hp one?

INDIAN BATTLE TANKS


The T-72


The T-72, which entered production in 1971, was first seen in public in 1977. The T-72, introduced in the early 1970s, is not a further development of the T-64, but rather a parallel design chosen as a high-production tank complementing the T-64.


The T-72 retains the low silhouette of the T-54/55/62 series, featuring a conventional layout with integrated fuel cells and stowage containers which give a streamlined appearance to the fenders. While the T-64 was deployed only in forward-deployed Soviet units, the T-72 was deployed within the USSR and exported to non-Soviet Warsaw Pact armies and several other countries. In addition to production in the USSR it has been built under license in Czechoslovakia, India, Poland and former Yugoslavia.


DESCRIPTION:


The T-72 medium tank is similar in general appearance to the T-64.


The T-72 has six large, die-cast, rubber-coated road wheels and three track return rollers. It has a 14-tooth drive sprocket and a single-pin track with rubber-bushed pins.


The gunner's IR searchlight is mounted to the right of the main gun. The 12.7-mm NSV anti-aircraft machine gun has a rotating mount, and there is no provision for firing it from within the tank. There are normally only a few small stowage boxes on the outside of the turret, and a single short snorkel is stowed on the left side of the turret.


The T-72 has a larger engine compartment than the T-64, and the radiator grill is near the rear of the hull.


CAPABILITIES:


The T-72 has greater mobility than the T-62. The V-12 diesel engine has an output of 780 hp. This engine appears to be remarkably smoke-free and smooth-running, having eliminated the excessive vibration which was said to cause high crew fatigue in the T-62. Although the engine is larger than that of the T-64, the heavier (41 mt) T-72 is believed to have approximately the same road speed as the T-64. The T-72B1 is powered by a multi-fuel V-12 piston air-cooled 840 hp engine that will run on three fuels: Diesel, Benzene or Kerosene. Two 200-liter auxiliary fuel drums can be fitted on the rear of the hull. The T-72 can be fitted with a snorkel for deep fording, and takes about 20 minutes to prepare for amphibious use.


The T-72 has better armor protection than the T-62, due to the use of layered armor and other features discussed above under T-64 capabilities. The advanced passive armour package of the T-72M and T-72M1 can sustain direct hits from the 105mm gun equipped M1 Abrams at up to 2,000 meter range. The later T-72Ms and T-72M1s are equipped with laser rangefinders ensuring high hit probabilities at ranges of 2,000 meters and below. The turret has conventional cast armor with a maximum thickness of 280-mm, the nose is about 80-mm thick and the glacis is 200-mm thick laminate armor. Besides the PAZ radiation detection system, the T-72 has an antiradiation liner (except on export models) and a collective NBC filtration and overpressure system.


The T-72 has the same integral smoke generating capability as earlier T-54/55/62, tanks, and variants have been observed with smoke grenade projectors mounted on the front of the turret.


The T-72 employs the same armament, ammunition, and integrated fire control as the T-64. The low, rounded turret mounts a 125mm smooth bore gun with a carousel automatic loader mounted on the floor and rear wall of the turret. The 125mm gun common to all the T-72 models is capable of penetrating the M1 Abrams armour at a range of up to 1,000 meters. The more recent BK-27 HEAT round offers a triple-shaped charge warhead and increased penetration against conventional armors and ERA. The BK-29 round, with a hard penetrator in the nose is designed for use against reactive armor, and as an MP round has fragmentation effects. If the BK-29 HEAT-MP is used, it may substitute for Frag-HE (as with NATO countries) or complement Frag-HE. With three round natures (APFSDS-T, HEAT-MP, ATGMs) in the autoloader vs four, more antitank rounds would available for the higher rate of fire.


The infra-red searchlight on the T-72 is mounted on the right side of the main armament, versus on the left on the earlier T-64. The 1K13-49 sight is both night sight and ATGM launch sight. However, it cannot be used for both functions simultaneously. A variety of thermal sights is available. They include the Russian Agava-2, French SAGEM-produced ALIS and Namut sight from Peleng. Thermal gunner night sights are available which permit night launch of ATGMs.


VARIANTS:

* T-72: Original Russian tank from which T-72 variants were derived.

* T-72A: The Russian variant differs from T-72 with the TPDK-1 LRF, added sideskirts, additional armor on the turret front and top, smoke grenade launchers, internal changes, and a slight weight increase.

* T-72B : has the thickened frontal turret armor and is commonly known in the United States as the Dolly Parton.

* T-72BK: Commander's variant with additional radios

* T-72BM: Version with 2nd Generation Kontakt-5 explosive reactive armor similar to that on the T-90. This system is being fielded and is available for export.

* T-72M: Original Polish and former-Czechoslovakian T-72-series tank from which Polish/Czechoslovakian T-72M1 was derived. T-72M differs from T-72 in replacing the right-side coincident rangefinder with a centerline-mounted TPDK-1 LRF.

* T-72M1: Russian export version and Polish/Czechoslovakian counterparts. Versions with Kontact ERA are known as T-72AV /T-72 M1V. Some countries have inventories of T-72, T-72M and T-72M1, with different versions of each variant.

Also, many variants were upgraded or modified. Some T-72M1s do not have smoke grenade launchers or track skirts. Some T-72s/T-72Ms have smoke grenade launchers. More reliable discriminators are armor and rangefinder/FCS.

* T-72S/Shilden: Russian export T-72A upgraded to be comparable to the T-72BM standard. Although similar to the T-72BM, it may have less turret front protection. The early T-72S tank has Kontakt ERA.

* T-72BV: with explosive reaction armor packages fitted to the hull and turret. The glacis plate is covered with a layer of single ERA blocks while the turret is covered by one, two or three layers with one being the more usual.

* T-90: Successor to T-72BM. This tank has been tentatively approved for production and adoption as a standard tank, alongside the T-80U, for the Russian army. The T-90 uses the gun and 1G46 gunner sights from T-80U, a new engine, and thermal sights. Protective measures include Kontakt-5 ERA, laser warning receivers, and the SHTORA infrared ATGM jamming system.

INDIAN BATTLE TANKS


The T-90 S

The T-90S is the latest development in the T-series of Russian tanks and represents an increase in firepower, mobility and protection. It is manufactured by Uralvagonzavod in Nizhnyi Tagil, Russia.


The T-90S entered service with the Russian Army in 1992. In February 2001, the Indian Army signed a contract for 310 T-90S tanks. 124 were completed in Russia and the rest are being delivered in 'knocked down / semi-knocked down' form for final assembly in India.


The first of these was delivered in January 2004. The locally assembled tanks are christened 'Bhishma'. The tanks are fitted with the Shtora self-protection system and Catherine thermal imagers from Thales of France and Peleng of Belarus.


By November 2007, it has been estimated that the Russian Army has around 200 T-90 tanks. In August 2007, Thales was awarded a contract to supply 100 of these with the Catherine FC thermal imager.


In November 2006, India ordered a further 300 T-90 tanks, to be licence-built by Heavy Vehicle Factory (HVF), Avadi. Deliveries are to begin in 2008.


ARMAMENT

The T-90S armament includes one 125mm 2A46M smoothbore gun, stabilised in two axes and fitted with a thermal sleeve. The gun tube can be replaced without dismantling inside the turret. The gun can fire a variety of ammunition including APDS (Armour Piercing Discarding Sabot), HEAT (High Explosive Anti-Tank), HE-FRAG (High Explosive Fragmentation) as well as shrapnel projectiles with time fuzes.


The T-90S gun can also fire the 9M119 Refleks (NATO designation AT-11 Sniper) anti-tank guided missile system. The range of the missile is 100m to 4,000m and takes 11.7 sec to reach maximum range. The system is intended to engage tanks fitted with ERA (Explosive Reactive Armour) as well as low-flying air targets such as helicopters, at a range of up to 5km. The missile system fires either the 9M119 or 9M119M missiles which have semi-automatic laser beamriding guidance and a hollow charge warhead. Missile weight is 23.4kg. The guns automatic loader will feed both ordnance and missiles.


Also fitted is a coaxial 7.62mm PKT machine gun and a 12.7mm air defence machine gun. A 5.45mm AKS-74 assault rifle is carried on a storage rack.


SELF-PROTECTION

The T-90 tank is protected by both conventional armour-plating and explosive reactive armour (ERA).


The T-90 is fitted with the Shtora-1 defensive aids suite which is produced by Electronintorg of Russia. This system includes infrared jammer, laser warning system with four laser warning receivers, grenade discharging system which produces an aerosol screen and a computerised control system.


It is also fitted with NBC (nuclear, biological and chemical) protection equipment.


FIRE CONTROL AND OBSERVATION

The T-90S has the 1A4GT integrated fire control system (IFCS) which is automatic but with manual override for the commander. The IFCS contains the gunner's 1A43 day fire control system, gunner's TO1-KO1 thermal imaging sight which has a target identification range of 1.2km to 1.5km and commander's PNK-S sight.
"The T-90S has the 1A4GT integrated fire control system (IFCS) which is automatic but with manual override."


The gunner's 1A43 day FCS comprises: 1G46 day sight/rangefinder with missile guidance channel, 2E42-4 armament stabiliser, 1V528 ballistic computer and DVE-BS wind gauge.


The commander's PNK-4S sight includes a TKN-4S (Agat-S) day/night sight which has identification ranges of 800m (day) and 700m (night).


The driver is equipped with a TVN-5 infrared night viewer.


PROPULSION

The T-90S has a liquid-cooled V-84MS 618kW (840 hp) four-stroke V-12 piston engine. This engine can be fuelled by T-2 or TS-1 kerosene and A-72 benzine, in addition to diesel. The tank can carry up to 1,600 litres of fuel in the main fuel tanks and fuel drums. The fuel tanks are reinforced with armour plating.


The tank is provided with a snorkel for deep fording and can ford 5m of water with equipment which can be deployed in 20 minutes.


The mechanical transmission includes primary reduction gear, two planetary final gearboxes and two planetary final drives. The running gear features torsion bar suspension with hydraulic shock absorbers at one, two and six road wheel stations and tracks with rubber-metallic pin hinges.

Been reading too much Rakshack? In terms of the Arjun v. T90 nonsense the guy either spread some factitious claims or the competition was staged, and now many look at the T-90 as a second class tank. I find it ironic that the T-90's performance in exercises and competitions in Russia and in India have revealed that the tank has excellent if not world class hit rates, rate of fire, accuracy and mobility yet it does poor against the Arjun? Something is not right.

Read this before proclaiming the tank to be junk:


T-90 - a knol by Anonymous



During one of the displays, T-90 struck 7 targets in 54 seconds. All were at the distance between 1500-2500m and the tank was on the move at 25km/h. While returning to position, the layer gave the control to the commander who used the gunner mode to fire to the rear of the vehicle and hit 4 more targets.



during the official trials of T-90, all of the ammunitions were fired by young conscripts who just finished training. All of the rounds – 24 of them, hit targets at a distance of 4-5km.


Indian crews quickly mastered the T-90S, they also did not have problems with the fire control and thermo-vision systems. Just after several training sessions Lt. Kapur of the Indian army acted as layer who accurately fired on to the targets at 2500-3000m. Officers from one of the panzer corps needed 20 minutes to familiarize with T-90S and successfully complete the task of destroying 4 targets at night from a distance of 3100m at an ambient temperature of 47°C.





Further, Russian tanks have a bad rap from the Gulf War but the truth is the Iraqi Army mostly used Chinese Type 69's, the T-72's that Iraq had were actually locally assembled tanks with mismatching parts.

Also the effectiveness of Russian reactive amour:


Kontakt-5 - Wikipedia, the free encyclopedia

The effectiveness of Kontakt-5 ERA was confirmed by tests run by the German Bundeswehr and the US Army. The Germans tested the K-5, mounted on older T-72 tanks, and in the US, Jane's IDR's Pentagon correspondent Leland Ness confirmed that "when fitted to T-72 tanks, the 'heavy' ERA made them immune to the depleted uranium penetrators of M829 APFSDS, fired by the 120 mm guns of the US M1 Abrams tanks



Interestingly to destroy some T-72 variants the kinetic energy rounds will have to penetrate the equivalent of 20 inches of steal. Obviously the T-90M or T-90AM has improved amour both regular as well as reactive.

I have heard 1200-1500, the important thing is power-weight-ratio, and the T-90 has excellent numbers. The T-90's diesel has an advantage over gas turbine engines in the fact that it is more efficient. The T-90 has superior range over other tanks meaning it will not need entire fuel convoys following it around. Diesels also have outstanding torque, important for steep inclines and power wise the T-90's diesels are producing similar numbers to gas turbine engines.

I also have not heard any weight figures for the new T-90M although it does appear to have a larger turret. It also seems to have reactive amour covering most of the hull especially a good portion of the tracks, something that is important in my opinion because intact track will allow the tank to stay Mobil. The T-90 also has a grill covering the rear of the tank, this is made to defeat RPG's. All this could mean more weight but I have not heard any exact weight figures.

why not to induct more arjuns may be half the no. of t 72 but dear friends they will be more than twice as effective leave and come over this russian junk...... really these all tanks are junk when compared to modern tanks like merkava or leopard or even the luckrack ............

You are the first Indian to call Russian tanks Russian junk. I'm proud of you that you see the light. India should look into getting some M1A3 tanks and ditch everything else.
