Arjun Mk II
DRDO chief VK Saraswat said the German engine on the current version of the tank would be replaced by an Indian power plant and the new variant (Arjun Mk-II) would have 90% indigenous component. Saraswat, also the scientific adviser to the defence minister, told HT at Aero India-2011: "The new variant will have high indigenous quotient, except for some hydraulic and electronic systems. The tank should be ready in early 2014. It will feature several modifications including superior missile firing capabilities. On June-2011 the Mk-II begun to undergo trials at Pokhran ranges in Rajasthan. The Mk-II is also expected to go through its winter trials later the same year.

According to CVRDE the Director P. Sivakumar, the Arjun Mark II will have a total of 93 upgrades, including 13 major improvements. The major upgrades would be missile-firing capability against long-range targets, panoramic sight with night vision to engage targets effectively at night, containerisation of the ammunition, enhanced main weapon penetration; additional ammunition types, explosive reactive armour, an advanced air-defence gun to engage helicopters; a mine plough, an advanced land navigation system and a warning system which can fire smoke grenades to confuse laser guidance. Other upgrades are an enhanced Auxiliary power unit providing 8.5 KW (from 4.5 KW) and an improved gun barrel, changes in the commander's panoramic sight with eye safe LRF, night vision capability including for driver, digital control harness, new final drive, track and sprocket.

Arjun tank hull and turret has been modified to achieve the target weight of about 55 tons from 59-64 tons. Elbit is helping to enhance its firepower and battlefield survivability and IMI is helping to augment Arjun Mk II's mobility, redesign its turret and hull and improve its production-line processes.

The development trials of the Mark II tanks started on June 22, 2012, at Rajasthan's Pokhran field firing range which will continue for the next two months and will mainly focus on 19 parametres, according to DRDO spokesperson Ravi Gupta. DRDO will start production of 124 Arjun Mark II tanks for the Indian Army after the success of these trials. The tank commander's thermal imaging (TI) night sight, the tank's operation in "hunter-killer" mode, the tank's missile firing capability from its main gun, and a laser missile warning and counter measure system are among the crucial upgrades that will be tested.

This says that modified Arjun tank hull and turret has been modified to achieve the target weight of about 55 tons from 59-64 tons.


The turret and glacis are heavily armoured and use "Kanchan" ("gold") modular composite armour. The Kanchan armour got its name from Kanchan Bagh, Hyderabad, where the Defence Metallurgical Research Laboratory (DMRL) is located. The armour is made by sandwiching composite panels between Rolled Homogenous Armor (RHA) to defeat APFDS or HEAT rounds. During the trials in 2000, the Kanchan was able to withstand a hit from a T-72 at point blank range, and was able to defeat all available HESH and APFSDS rounds, which included the Israeli APFSDS rounds.

This says that "During the trials in 2000, the Kanchan was able to withstand a hit from a T-72 at point blank range, and was able to defeat all available HESH and APFSDS rounds, which included the Israeli APFSDS rounds.

Earlier sources were claiming otherwise.

What types of ammunition, give me their designation codes, not that these were APFSDS and HESH, because this means nothing. And is good for layman like You.

Arjun Mk.2 Main Battle Tank | Military-Today.com
link which says it is modelled on LEOPARD.
which also says that the weight is reduced to 55 tons.I don't whether this is with or without ERA and other add ons. I will clarify and post it later if it is correct.

Your link leads to a website where everybody can become an editor... reliable as hell. There is no German source nor any Indian source claiming that the Indians and the Germans cooperated. The Arjun is not "modelled on LEOPARD" it just looks similar. That sums up everything these two tanks have in common.

 

[Damian]

To be honest only Arjun turret is a bit similiar to Leopard 2... rest not so much.

What I said was that arjun has been modelled on LEOPARD based on the western tank design philosophy.
I never said that it was license built from german LEOPARD tech.
No tech from LEOPARD was transfered.
There is a world of difference when we say modelled and TEch transfered.
The LCA was modelled on the mirage and a bit of F-16 XL.
But no tech was transferred.The same analogy here.
Same higher weight, better armour philosophy of LEOPARD was followed.
And RENK transmission was employed.
I dont pass of myself as editor and the final authentic source .

 

[Kunal Biswas]

Arjun MK1 = 58 tons..

Arjun MK2 = 67 tons, Earlier projected as 62 tons..

FMBT = 55 tons..

 

[ersakthivel]

Earlier sources were claiming otherwise.

So please admit you have no reliable source in this matter.

What types of ammunition, give me their designation codes, not that these were APFSDS and HESH, because this means nothing. And is good for layman like You.

We should wait for KUNAl's clarification regarding ammunition, since laman like me who forage the net like peasant wont have any credibility in your eye.
So please admit that you don't have any up to date knowledge on ARJUN's armour and it's trials either, since you are asking this question to me.

 

[ersakthivel]

Arjun MK1 = 58 tons..

Arjun MK2 = 67 tons, Earlier projected as 62 tons..

FMBT = 55 tons..

Is this short ton or metric ton?
with or without mine ploughs and other add ons?

Arjun Mark II Battle Tank with New Upgrades Undergoes Trials in Rajasthan for Army

The Arjun tank hull and turret has been modified to achieve the target weight of about 55 tons from 59-64 tons. Israeli firm Elbit is helping to enhance its firepower and battlefield survivability and IMI is helping to augment Arjun Mk II's mobility, redesign its turret and hull and improve its production-line processes.

Are reports like this false or accurate? Do they mention the short tons or actual tons/ with addons or with out addons?

This is what wiki says

Then the report that it's turret was redesigned to reduce weight from 58.5 ton to 55 ton true or false?
I would accept your words as final as you have army background.

Arjun Mark II Battle Tank with New Upgrades Undergoes Trials in Rajasthan for Army

In an earlier statement, DRDO chief VK Saraswat had indicated that the new variant (Arjun Mk-II) is likely to achieve 90% indigenous component.

Broadsword: Heavier, more lethal Arjun tank poised for trials

The Arjun Mark II's most remarkable feature is its extra weight, 3-4 tonnes more than the earlier 62-tonne Arjun. For years the army criticised the Arjun as too heavy for India's road and rail infrastructure; now it wants modifications that will make the Arjun heavier. Fitting Explosive Reactive Armour (ERA) plates on the tank has boosted crew protection, but also increases the weight by one and a half tonnes. An equivalent increase comes from added mine ploughs, which churn up the ground ahead of the tank, uprooting explosive mines that would otherwise blow up the tank.
CVRDE chief, Dr P Sivakumar, an award-winning transmission specialist, is jubilant. "Earlier the army was criticising my Arjun [for weighing too much]. But, after seeing its cross-country performance, even compared with a lighter 40-tonne tank like the T-90, they realise that the Arjun moves like a Ferrari. Even at 65-66 tonnes, it will beat any MBT in the desert," he promises.

So what is the exact weight?

Arjun is our own design. The design shows nobody from the west helped.

Edit: The problem with Arjun is there is nobody related who has written a decent book about its development to date.

 

[ersakthivel]

But in the above post it says that the mine plough weighs 1.5 tons.
1.ERA adds another 1.5 ton.
2.The arjun Mk-I weighs 59 tons.
With the addition of the 3 ton weight from ERA(1.5 ton) +mine plough (1.5 tom) the tamk weight is reported to be 59+3 =62 tons.
But it does not mentions the weight reduction exercise done on ARJUN MK-I's turret and hull to reduce it's weight from 59 to 55 tons as reported by V.K.saraswat interview.
Then what is the exact weight of erjun mk-II?
Is it this reduced 55tons+3 tons=62 tons
or
the old arjun mk-I weight of 59+3 =62 tons?
or quoted as 67 tons in many other sources?

 

[Kunal Biswas]

Is this short ton or metric ton?
with or without mine ploughs and other add ons?

In Metric tons, With all equipments..

 

[Kunal Biswas]

What types of ammunition, give me their designation codes,

We should wait for KUNAl's clarification regarding ammunition

Back in 2000 :

3BM-15 is in service in Indian army back in 2000 and still used in training..

-------------------

CL 3254 and as the MK-1..

Well, this only prooves what I said, Kanchan armor was not tested against best APFSDS ammunition, but against ammunition avaiable for India... ~460mm penetration is not something anyone should be proud.

 

[Kunal Biswas]

These test were carried out in 2000 more than a decade ago, Kanchan which is similar to Burlington Armour have layers which are increased and can be decreased as per thread analysis, Over the years these layers are improved as ARDE continuously improve the Armour based on latest ammo India gets from different sources, Anyways this test was the only one published in public, Rest are only circulated in inner circle which is private..

 

[Damian]

Still it is doubtfull that Kanchan was tested against modern and the best APFSDS ammunition for several reasons.

1) USA do not export their M829 series, and especially not the best currently used variants M829A2 and M829A3.
2) India could obtain German DM53 and DM63 but there is again another problem, also connected with M829 series... from what You would fire these rounds if India do not use a 120mm smoothbore gun?
