We have discussed that umpteen number of times on the T-90 thread. Check it out. Everybody knows I am not a fan of either the Arjun Mk1 or the LCA mk1.You are talking bs here man.Arjun mk1 has already outclassed the T90S by far in both firepower
and armor.There is no doubt about it.I have seen for long that you are a diehard russian fan or should I say a fanboy.Without the Kontact5 the T90 can't even withstand a single RPG7 and Kanchan mk1 withstood hits from even Kornet ATGMs.Even multiple Israelly 125 mm FSAPDS T rounds and the indian mk2 rounds fired from T90 at point blanck range could not defeat the Kanchan armor.That should answer your question.
And please don't talk about the firepower of the 2A46 gun that fires only 550 mm long penetrtors which have a mere weight of 7 kg.On the other hand the ARDE L52 fires 950mm longrod rounds with a weight of 10.8 kg and are fitted with hardened ballistic caps.Both guns have same mussel velocity of 1720 meter/sec.So now you decide which one is better,but to understand you need to know about physics.
In fact if both gun use tungsten rounds the ARDE L52 beats the Rheinmetal L44 smoothbore handsdown which has a mussel velocity of just 1550 meter/sec.
Beside most people think that the Arjun's guns are less powerful because it is rifled.The spin from rifling bleeds some of the kinetic energy into rotating motion.But ARDE scientists overcame this problem by a simple but brilliant innovation-they used barings into the sabot,so that while travelling through the barrel the sabots starts to spin but the rod remains linear.So Arjun has got a rifled gun that is just as powerful as a smoothbore one of same length but in addition can also fire HESH rounds that are must against concrete pil boxes and that smoothbore guns can't fire.
REGARDS....
At the same time the senior officials on the T-90 say it will continue costing the same at 11 Crores per unit. So, is 3 times the cost justifiable for a capability which is only slightly better even if it is proven to be better? What if the new version of the T-90 is much better in overall survivability and lethality at a slightly higher cost? So, like I said, Army knows best."If everything goes on track, Heavy Vehicles Factory here will roll out its first batch of Mark II by the end of 2014 and a unit will cost Rs 35 crore. Mark II will have 90 per cent Indian components in its making," the official added.
Exhaust Pipe?any one has any idea as to what that vertical pipe like structure with black top on the top of Arjun tank is for ???
Very interesting points from the long article. My question would be whether some of these upgrades can be retrofitted on the T-types as well? It would be really good to have this system on all tanks and IFVs, iron fist or trophy would do.As of April 2011, Heavy Vehicles Factory (HVF) Avadi had delivered 101 tanks to the Army.
Top New Features in Arjun Mk-II
Ability to fire anti-tank guided missiles through the tank's main gun.
Extra protection for the tank's crew through explosive reactive armor, or ERA
Thermal imaging panoramic sights that allows the Arjun's commander to scan his surroundings even by night.
An automatic target tracking (ATT) system which will add to the accuracy when firing on a moving target.
Advanced air defence gun system for firing at attack helicopters.
Enhanced Auxiliary Power Unit (APU) with a capacity of 8.5 KW (against Mark I's 4.5 KW).
Mine Plough.
Advanced Land Navigation System (ALNS)
Digital control harness.
Improved gun barrel with an Equivalent Firing Charge (strength of the barrel to sustain firing) of 500 rounds against T 72's 250 rounds.
Indigenous engine will replace the German engine of the 58-tonne Arjun Mark-I.(none of that nonsense from Prasun)
In phase I, 45 tanks will roll out with 56 upgrades, including the missile firing capability and the commander's panoramic sight with night vision. Phase I production of Arjun Mark-II will be completed by July 2011
In phase II, the remaining 79 tanks, with all the 93 improvements, will come off the assembly line. "By 2013-14, the first batch of around 30 tanks will go out," Dr. Sivakumar said. Phase 2 production will be completed by June 2012.
"After the testing, the MBT will go for a first user trial in October 2011 and production is expected to start from July 2012 after the second user trial," the official said.
"We had test-fired the Israeli LAHAT missile through the Arjun gun as far back as in 2005," said Sundaresh. "It will take us about six months to integrate the LAHAT's designator into the Arjun's fire control system."
"The ERA will protect the Arjun's crews from enemy missiles. Initially we will fit the same Russian ERA that protects the T-90 and the T-72. But, we will also develop our own indigenous ERA."
The HVF can deliver upto 50 tanks in a year.
According to unconfirmed reports Arjun Mk-II will be equipped with a Laser Warning Systems developed by Elbit of Israel.
According to unconfirmed reports Arjun Mk-II will also be fitted with the Iron Fist APS (Active Protection System) developed by srael Military Industries (IMI). (interesting)
Didnt the Arjun Mk-1 out perform the T-90 in comparative trails and an neutral auditor also said it was a good tank! Then what is wrong now?We have discussed this earlier. The Arjun Mk2 is meant to equalize or exceed the T-90 in armour and firepower depending on the version of T-90 we are talking about. The Mk1 did not.
Only in mobility and accuracy. When it comes to firepower and armour the T-90 still comes on top. 2Didnt the Arjun Mk-1 out perform the T-90 in comparative trails and an neutral auditor also said it was a good tank! Then what is wrong now?
In a battle Mobility and Accuracy matter more than Armour because you need to hit the enemy not receive hits! Wont that make it more capable than T-90.Only in mobility and accuracy. When it comes to firepower and armour the T-90 still comes on top. 2
T-90 is cheaper and we have the infrastructure to manufacture twice the number as compared to Arjun.
Could not get how the armour of the T-90 is better than Arjun. T-90 is cheaper and it doesnot mean that we shall allow our solders to burn inside the tanks. Till now 10 T-90 was produced by Avadi with kit from Russia. That is our infrastructure to produce T-90Only in mobility and accuracy. When it comes to firepower and armour the T-90 still comes on top. 2

So,where you would like to be in??By the way,the crew told that they would like to be in Arjuns in the time of war.
just check the armour of the two, you will know where you want to be at the time of war.
just check the competition at the same place
There is a serious misconception regarding the T-90s armour. Western analysts believe the T-90 that was designed in the 1990s had the same level of armour as the Leopard A4.Could not get how the armour of the T-90 is better than Arjun. T-90 is cheaper and it doesnot mean that we shall allow our solders to burn inside the tanks. Till now 10 T-90 was produced by Avadi with kit from Russia. That is our infrastructure to produce T-90
So, the RPG-29 penetrated the front armour of the Challenger II and the ERA over it. Quite gruesome isn't it that a Russian made weapon can penetrate the armour of god like tanks so easily. The Arjun is a lesser capable cousin of the Challenger II BTW. Now I don't even want to know what would happen to the Mk1 which has no ERA equipped.The Challenger 2 is reputed to be one of the most sophisticated tanks in the world and those used in Iraq by the British Army are built with Dorchester armour, the composition of which is top secret. The tank is also fitted with explosive reactive armour (ERA) at its front that should deflect any weapon fired at its hull.
the Challenger was damaged when a Russian-made rocket-propelled grenade, known as an RPG-29, defeated the ERA and penetrated the driver's cabin.
Even the beyond god like M1A2 with it's Depleted Uranium armour was penetrated. There goes the theory up in smoke.In one instance not previously disclosed, an American M1 tank was damaged by an RPG-29, an advanced anti-tank weapon.
The crew that is currently driving the Arjun moved from the T-72. T-72 is acknowledged to have a poorer armour. Then again, the crew will base this on crew comfort, which is another advantage on Arjun. I would rather drive a BMW than a Lorry, even though I know the Lorry can crush the BMW in a second.So,where you would like to be in??By the way,the crew told that they would like to be in Arjuns in the time of war.
The Rifled gun has superior accuracy. But bring the Arjun against a Challenger and all accuracy claims go to naught. The Arjun can fire briefcase targets from 2Km, but Challenger can fire a backpack size target from 4Kms away. Experience tank crews will do it from 6 Kms away. Even after all that, there is a reason why the T-90 crew is still feared.In a battle Mobility and Accuracy matter more than Armour because you need to hit the enemy not receive hits! Wont that make it more capable than T-90.
The Challenger II and Abrams are being equipped with ERA for urban battles. The T-90 has excellent armour protection that is better than Arjun. This has been explained in my previous post.Also Arjuns heavier which means it has more Armour, it does not have Reactive armour but so do Challenger and Abrams, that does not make them lesser in Armour than T-90?
The T-90S costs 11 Crores. The Arjun Mk1 costs 17 Crores. This difference is not marginal. The T-90 also carries the latest French TIs while the Mk1 carries previous generation Israeli TIs. The T-90S has missile firing capability unlike the Arjun Mk1. The T-90M cost is unknown, but it won't be as expensive as the Mk2 at 35 Crores.The Tanks is marginally more expensive but it offers better mobility in level with western tanks. In our 4,000 strong feelt there is room for both Arjun and T-90.
Considering you believe in a "Developing World Standards" the T-90 is actually a "developed world standard."Arjun MK2 is a different story so lets not go there for the movement. Lets talk with Developing world standards.
The armour details are guarded. But most analysts still say the T-90 has a Leo A4 level of armour.Ok p2prada you gave a source regarding the armor is the most unreliable source.The armor thickness of a tank is the most closely guarded secret.So how can an individual author know that.
With out the Kontact5 the T90 can't even withstand a RPG7.On the otherhand Kanchan armor withstood hits from both the KonkursM ATGM and Kornet atgms without ERA.Besides in 2005 during trial the armor was found to be capable of withstanding both the 125 mm IMI shot and 125 ARDE mk2 shot from 2A46M at point blanck range.So there goes your theory of weak armor in Arjun.Besides the Arjun mk2 will be equipped with new slanted armor with NERA-ERA combo.
Now coming at the rounds.Just look at the rounds's length,it's 994 mm!one of the longest and heaviest T round in the world.As I said earlier,simple use of barings can solve the problem of rifled barrels.Besides V.K.Saraswat stated that ARDE has developed a new mk2 round with a heavier rod and much stronger propelant.But yeah,the 2A86 is much better for sure.
The MK1 has not been calibrated to fire the Lahat. It is a diferent story that the Lahat was fired in a test, but as long as the operational ones are not calibrated then it is no point.p2,just go through the HAPP website.There you should get all the details of 125 mm IMI rounds,125 mm ARDE mk2 rounds and the 120mm ARDE mk1 rounds.The OFB website has not been updated for a decade or so.
I don't know how did that author get that armor detail. In 1985 the 1st prototype of Kanchan armor was made of a 1.5'' ceramic alumina tiles sandwithed between high hardened tungsten steel and limited quantity of glass fibers.The combined thickness of the two plates was 120mm or 5'' but their armor thickness was equivalent to 400 mm of rha against FSAPDS T rounds.So definately the complete armor had more thickness than atleast 600 mm against ke rounds.This block had defeated the 2A46M rounds from few hundred meter and also the 106 mm heat rounds from rcl guns.Arjuns don't use this armor anymore.Besides,as you said and I also know that india is using Kanchan armor in the T90Ms itself reveals that original russian armor of T90M is inferior.Otherwyse IA would not have been agreed.Besides according to the latest report Arjun mk2 will be 64 ton tank,so much more heavier armor than mk1 is for sure.Coupled with ERA-NERA combo the armor will be one of the strongest for sure.
It's not right that current ARDE L52 can't fire the LAHAT,in 2004 LAHAT was fired from that gun.Besides it's not weak either,because there is very few tank guns that can withstand a bore pressure of 860 mpa.Even the Israelies were very much impressed by overall design of Arjuns but they praised the Kanchan and ofcourse the gun the most.They even told that ARDE had found the gun 'accidentaly'.
