Arjun
http://www.fas.org/man/dod-101/sys/land/row/arjun.htm
At the end of the 1971 war, the Indian army realized the limitations of their tank fleet in the harsh desert conditions of Rajasthan, a northwestern Indian state bordering Pakistan, so they initiated their own MBT design. The first “Arjun” (named after a mythical Hindu warrior prince) concept was laid out in 1974 by the Combat Vehicles Research and Development Establishment (CVRDE) of the Defence Research and Development Organization (DRDO). Based on 1971 battlefield experiences, the Arjun would have a locally-designed, rifled 120mm main gun, a German, MTU-based diesel powerplant (The Indians consider turbine engines fuel guzzlers), and a computerized fire control system with a laser rangefinder.
One of the early Arjun prototypes was unveiled in April 1985, with a number of prototypes undergoing technical testing while desert trials were scheduled for that summer. At the time, it was reported to have a 120mm smooth-bore main gun and would use a 1400-hp MTU-based diesel until an indigenous one was ready. Weight would be about 50 tons, and the tank would cost about $1.6 million (U.S.). Development costs rose about 500 percent throughout the Â’80s, and through a development process plagued with delays, the end product visually resembles the German Leopard II, however, unlike the German vehicle, its future remains in doubt.
As of mid-2000 India planned to acquire T-90 tanks, based on field trials which had already been completed. Although orders had been placed for the supply of 124 Arjun tanks through the Defence Research Development Organisation, it would be difficult to predict when these orders would be fufilled. Until such time, T-90 tanks would serve to counter Pakistan's T-85 tanks.
Pakistan’s announcment in 1995 of a deal with Ukraine to purchase T-84s caused a flurry of activity in the Indian tank development community. And on 9 January 1996, the Arjun was formally unveiled and cleared for mass production. Considered comparable to the M1A2 Abrams, Leopard 2, and Leclerc, the 59-ton "15th Variant" can achieve a maximum speed of 70 kph (55 mph) and cross-country speed of 40 kph with its 1400-hp powerplant. The 1,610-liter fuel tank allows for a cruising range of 200 km (120 miles). To ensure crew survivability, production versions will have the indigenously-researched and developed ‘Kanchan’ composite armor, an automatic fire detection and suppression system, and an NBC protection system designed and built by the Bhabha Atomic Research Center.
The rifled 120mm gun, which includes a muzzle reference system, is made of ESR steel and is fitted with a thermal sleeve and fume extractor. All main gun rounds use a semi-combustible cartridge case with increased energy propellant for higher muzzle velocity and greater penetration characteristics. In addition to the usual suite of rounds, an anti-helicopter round is under development as well. The Arjun’s fire control system includes a laser rangefinder, ballistic computer, thermal imaging night sight, stabilized panoramic sight for the tank commander, and a secondary telescopic sight. The LRF (integral to the gunner’s sight) has a range of nearly 10 km and a thermal imager (which can “see”’ at around 5.5 km, recognize a target at 3.1 km and identify targets at 2.5 km). The Arjun fire control system’s ability to fire on the move during the night is a major step forward for Indian armored forces.
The Chassis and Automative System of MBT Arjun comprises main chassis, power pack (1400 HP engine coupled to hydromech transmission), running gear with hydropneumatic suspension, integrated fuel system, advanced electrical system and other dedicated special systems like integrated fire detection and suppression system. The chassis is fabricated from rolled homogenous armour plate using advanced welding technique. Frontal armour is of Kanchan composite sandwitched between armour plates. This fully integrated Arjun chassis and Automative System having smooth riding characteristics can be used as a mobile platform for any advanced weapon system. An extremely effective hydropneumatic suspension system has been developed for MBT Arjun. The suspension is externally mounted and provides vehicle springing and damping. It consists of one bogey wheel pair for each suspension station. Gaseous medium in the hydropneumatic suspension is for all terrain maneuverability for exploiting the power available. Casing and hub of the hydropneumatic suspension are sealed for preventing dust ingression and water seepage into the casing during operation in marshy area or shallow/medium fording. The MBT Arjun is fitted with double-pin steel track with detachable rubber pads. It is made out of steel casting having two bores for insertion of rubberised pins. It is an integral piece incorporating guide horns and has got a provision for insertion of detachable pads. The end connectors are induction-hardened in the area which comes in contact with the sprocket teeth to prevent wear.
The integrated fire and explosion suppression system developed for MBT Arjun is based on state-of-the-art technology. The indigenous development of this system is considered to be a breakthrough in the field of fire protection engineering. It is capable of suppressing hydrocarbon fuel fire/explosion resulting from an enemy hit on the tank or due to any malfunctioning of the engine, transmission or any electrical short circuiting. The system is based on infra-red detectors for the detection of fire/explosion in the crew compartment of the battle tank and a continuous type of linear thermal detector popularly known as fire-wire for the engine compartment. Halon-1301 has been employed as a fire extinguishing medium. The system is capable of detection and suppression of hydrocarbon fuel fire/explosion in the crew compartment within 200 milliseconds and in the engine compartment within 15 s thereby enhancing the chances of survivability of the crew and battle effectiveness of the tank.
Further improvements were deemed necessary even after the Arjun design profile was accepted again in July 1996. On 27 August 1996, the Defense Production and Supplies Secretary ordered 15 pre-production tanks from the Heavy Vehicles Factory, Avadi (at which point, estimates placed the project cost at $112 million). As of mid-1997 the list of faults after 20 years of development was not encouraging. In addition to numerous technical modifications to its fire and gun control systems, the fire control system in particular has been found unable to perform in temperatures above 42 degrees Celsius (108° F). The DRDO has been considering scrapping the current Arjun fire control system in favor of whatever is accepted for the T-72M1 upgrade program. Defects noticed during the user trials of the Arjun Mk.1 MBT, including over-heating of the engine in Rajasthan desert areas, had supposedly been “by and large overcome” while other complaints were being addressed.
The first 120 tanks to be built would cost $4.2 million each, while other cost estimates places the figure at $5.6 million each per tank by 2001, given a purchase of 124 tanks to equip two regiments. Production of the first batch of tanks might take more than the planned five years, given the capacity at the Avadi factory.
Planned Arjun variants include mobile assault guns, an observation post vehicle, an air defense (gun or missile) version, a recovery vehicle, an engineer vehicle, and bridgelayers. New bridgelayers and recovery vehicles were necessary, given the ArjunÂ’s substantial weight increase over the T-72M1 series.

I think we have alot to learn from the Indian army especially in their armour. They have combat experience as they have fought in 3 major wars with Pakistan and many smaller military conflicts. They also have the capability to upgrade and develop new MBTs something which we cannot do at the moment as least not officially. After all if they are not good we won't have sent our troops there for exercises. I have seen pics and black and white clips of the Indians with the AMX-13. There is a bit of irony as some of the AMX-13 which we have are gotten second hand from the Indians and now these tanks are back in India!

When did it happen and when AMX-13 was returned? -
Please check out the video clips of the wars, especially the military operations carried out by the Indian army straight after they gained independence from the British, when Pakistan is being created.That is when i first saw the AMX-13 in action in India.
I am personally trained as a tank commander as the AMX-13SM1 ( upgraded version of AMX-13) during my NS so i know that some of the tanks are gotten from India because of certain structural differences. We got our second hand AMX-13 from at least one other source.
The tanks are back in India when they carried out exercises and training in India not too long ago and i have heard they are sending personnel there for training on a regular basis.Reserve/Store MBTs

Tankee? I think u r another Indian. We learn from India armed forces and they r very good in upgrade? R u nuts? Their Arjun failed terribly which they failed to admit due to pride! (Why they keep buying and license produce T-90 from Russia?)

For info all our AMX-13 is upgraded by our ST and we have no problem and no need to learn from India.. Maybe anti-submarine warfare which in these areas which we can learn from them but armour warfare is a no,no and their technology is even worst! -
Their Arjun MBT is indeed met with many problems and delays but there is without a doubt and one cannot deny this fact that they did come out with Arjun and upgrades of MBT (Tank Ex). However, their true capabilities can only be assessed during war time or by internationally recognised agencies such as Janes during peace time. Things may look nice on paper but that doesn't mean they work, this is also a fact.
We indeed sent personnel there for exercises and training which is another fact. I am sure the big brass in Mindef must have good reasons to ship the vehicles and fly our troops there as India is after all quite a distance away from SEA.Originally posted by zenden9
Well to be fair, quite a fair bit of our technology is acquired through cooperation with other countries. Examples are chemical and submarine warfare with Sweden, armour warfare with Israel and so on. Currently we do not have the capability to make or upgrade MBTs at least not officially. Yes, we are good, no doubt about that but there are always others out there in this world who are better in some aspects. Sometimes humility is a virtue no?

I always thought that the reason for training in India is the result of the reduction of training in Taiwan (compared to 20 years ago).
China had offered Hai Nan, as a counter to Singaporeans training in Taiwan.
Instead of having to choose between China and Taiwan, in my opinion, its best to stay out of the China/Taiwan politics, and conduct training in another country instead (India). Singapore has a unique relationship with both Taiwan and China, and I hope we don't have to take sides.
India is seen strategically as an alternative to China. -
So what? I come out with something but it cannot works! Does this show what? I am still capapable? What kind of logic u r using???

The Arjun MBT failed again during the off road and firing test. The India land army reported the bad news to the government. They found that the firing control system had serious malfunctions during the normal firing test. And the flexibility is worse than T-90. The department of defense of India said that the Arjun is a useless tank. One retired general said that more than 60% of Arjun's parts depend on imports. And before 2008, over 1500 active tanks will retire. The officer said that the Arjun will be a training tank only, not used in war, since it is too heavy to handle. (Arjun is 60 Tons, T-90 is 46.5 Tons) T-90 tanks will swiftly" kill" the Arjun, the main battle tank developed locally for 25 years.Originally posted by tankee1981:

The Arjun has failed the engine test in the Thar desert and later it was all solved and offered for test. The purchase of T-90 is because it is cheaper than the Arjun. The army will use T-90 for numerical superiority and the Arjun for qualitative superiority.anti-submarine warfare which in these areas which we can learn from them but armour warfare is a no,no and their technology is even worst!
Boasting will not help right.
The experience Indian's have in the armour warfare can be read from the link provided.

Battle of Asal Uttar
From the reading you can easily conclude that it is not just tanks but training, leadership qualities, tactics all matter. You have a fine example how a well trained IA routed the an army with the best tech (Patton tanks) -
Serious questioning! If u say numerical superiority,T-72M1 will be a better choice,more cheaper and can easily mass produce for India since India co-produce with Russia. Btw,T-90 is not a cheap. The last I heard of Arjun news is that,they want to switch the Arjun chasis to T-72 one to reduce weight and for easy of transportation..Other than that,I think the problem of Arjun still persists....Originally posted by arjun:The Arjun has failed the engine test in the Thar desert and later it was all solved and offered for test.

T-72M1 is already produced in India in great numbers. The first batches of T-90's will be assembled in India and then the production of it instead of the T-72 will start in India. The T-90 is not cheap as the T-72 but we require a tank that is much better than the T-72 but cheaper than Arjun. And this T-90 will be mass produced in India.The last I heard of Arjun news is that,they want to switch the Arjun chasis to T-72 one to reduce weight and for easy of transportation..Other than that,I think the problem of Arjun still persists....
That is the Tank-Ex the experimental tank. There is no such restriction as such. It depends on the IA. But the Arjun production has commenced at Avadi and the first batch of tanks have already rolled out. The army has ordered 120 tanks in the first batch. The third picture is from the roll out ceremony of Arjun in Avadi.The last I heard of Arjun news is that,they want to switch the Arjun chasis to T-72 one to reduce weight and for easy of transportation..
The problem with transportation was that the Arjun tank is somewhat bigger or belongs to the biggie league, so they did not fit exactly into the rail wagons. The sides protruded outside it. So they had build new rail transporters pecially for the Arjun to be transported. It solved that problem also. -
Again,why needs three type of tank? T-72M1 for mass number? T-90 also for mass number? Arjun as the elite but in quality number? T-90 is only procure in 300 not as the mass as u stated but definitely more than the 126 Arjun. I'm wondering how T-90 is going to be in mass number?Originally posted by arjun:T-72M1 is already produced in India in great numbers.

It is not as simple as u think,JUST BUILD A NEW TRANSPORT WAGON FOR ARJUN AND CAN SOLVE THE RAIL PROBLEM??? OMG!!!

As per the agreement, 120 tanks will be delivered in a ready-for-use configuration, 90 in semi-knocked down (SKD) kits and the final 100 in completely-knocked down (CKD) kits. The SKD and CKD kits will be assembled at the Heavy Vehicles Factory in Avadi, Tamil Nadu and the first tank was delivered to the Army on 07 January 2004. Chief of Army Staff, General Nirmal Chander Vij stated that local production of the tank would begin in 2006-07, after the assembly of the CKD kits.
General Vij also stated that the T-90S MBT would constitute 30% of the Indian Army's combat tank force.I like yr way of addressing the problem Laughing Build new rail trnasporter and problem solve??

You are not transporting that big. The difference was for some feet. Do you think that all the tunnels are all made in such a manner that even one feet will make it un transportable. This transportation is from Avadi to the northern areas. Once in northern areas it did not require any transport to move to the border. -
hey, sorry to ask a dumb question.
Who is India's potential Rival tat requires India to have such numbers and heavy (60ton) mbt?
I imagine the northern part of India's border to be a lil "tank-unfriendly". Can help enlighten me pls?
=) -
So u think the differents of the new transporter is in one feet only? Arjun is definitely build with intent to counter Chinese tank too! Which will be needed to move to the east of northern part! How is it going to reach the northern part with a unsuitable railway transporter? If as simple as building new transporter is going to solve Arjun transport problem. I don't see India armed forces kick a big issue on the rail part! Maybe u can enlighten me with a sourcè or it is all along an assumption by u that this problem can be easily solve by 1,2,3?Originally posted by arjun:You are not transporting that big.

India's Battle Tanks Arjun Operationally Useless
Pakistan Times Foreign Desk Report
NEW DELHI (India): India's defence production authorities handed over the first batch of first five "indigenously-developed" Arjun main battle tanks (MBTs) to the Indian army on August-8.
However, according to diplomatic sources, the Indian army chief has expressed skepticism about combat worthiness and operational mobility of the tank.
The Main Objection
The main objections raised by the army headquarters are that with its excessive weight and width, the Arjun tank has poor operational mobility.
It will not be possible to rapidly move it from one area of operation to another on the existing tank transporters on our rail network."
Secondly, the Arjun weighs 58.5 tonnes. As such, it outweighs the newly-inducted 46.5 tonnes T-90S Russian MBT by 12 tonnes. "Being heavier than the Russian substitute, it is too heavy to transport over most border bridges in India".
Arjun is not only less manoeuvrable, but also suffers from recurring engine and fire-control-systems problems.
I scare the new transporter and Arjun will fall off the bridge! Mr Arjun,how r u going to solve the bridge part? By deciding not to use the bridge? Or by rebuilding the whole many,many bridge in India for the sake of Arjun? -
Up till now after more than 30 years of development at cost even more than the development of M1, InAF has yet to accept any Arjun tank into svc!!!!
And that the facts.
Yes, InAF was forced to order abt 124 Arjun a few years back without meeting their requirement and only last year, 5 were delivered to InAF for trials again and still InAF complained abt all kind of problems from this batch.
At this moment, there is no further news after that, full production of Arjun is still unknown becos of the failure of the trial last year. -
The Arjun not only suffer all kind of problems like too heavy for certain terrain in northern India , bridges etc, too big for rail transport etc but all this are problems are well known way before the trials in 2005.
So InAF already know that and accept them eventhough the Arjun will never fully meet the InAF requirement of weight and size even before the trail in 2005.
And yet it still fail the trial due to other reasons like problem with FCS, mechanical reliability, engine and lastly even the T-90 vs Arjun trial.
People already nicknamed it as "Arjunk"!!!! -
gary long time no see!
-
Arjun is definitely build with intent to counter Chinese tank too!
In the Himalayas tank war is not possible. Only infantry and artillery.Maybe u can enlighten me with a sourcè or it is all along an assumption by u that this problem can be easily solve by 1,2,3?
The defence minister himself has said this in 1995 or something that the problem is solved. Now don't be bothered how the tank will be transported. The IA will do it. They are in Rajasthan means they can be transported and already transported to the border.
Don't bring paki source here if you don't want to see the most unreliable reports and wrong statistics. If you love lahori logic and madrassa maths please do it.Yes, InAF was forced to order abt 124 Arjun a few years back without meeting their requirement and only last year, 5 were delivered to InAF for trials again and still InAF complained abt all kind of problems from this batch.
Why the Indian Airforce require these tanks. To make them fly.The Arjun not only suffer all kind of problems like too heavy for certain terrain in northern India , bridges etc, too big for rail transport etc but all this are problems are well known way before the trials in 2005.
Why you people brag that the Arjun is too heavy. It is not your or my problem to say that the Arjun is heavy so must not be fielded. The Arjun was build to counter the M1A1 which the Pakistanis were supposed to acquire. So it is meant to be heavy tank.
Telling the same again and again will not help. You are seeing the Arjun's rollling out from the factory after fixing all the problems and let's wait to see them in the next military exercise. -
Cool kit for soldiers in tanks
http://www.telegraphindia.com/1060506/asp/frontpage/story_6189609.asp
Ranchi, May 5: IndiaÂ’s main battle tank will never be the same again.
A team of engineers, led by Suchitangshu Chatterjee, from the Ranchi-based Metallurgical and Engineering Consultants (Mecon) Ltd, has developed the technology to keep gunners cool in the confined space and for a long period.
The device, smaller than a tabletop computer, took eight years to develop. It was tested in desert conditions on IndiaÂ’s western front and in Chennai, where the main battle tank, Arjun, is built, says a communication from the Defence Research and Development Organisation (DRDO).
The army has found it suitable for use.
An elated Chatterjee told The Telegraph that only the US had the technology so far to keep a tank in motion “cool”.
Conditions inside a tank, he said, are demanding and the temperature hovers between 45 and 50 degrees Celsius. Sitting in the cramped conditions and in such heat takes a toll on the toughest of soldiers. Many gunners have suffered anxiety syndrome, loss of memory and even temporary insanity.
An airconditioner cannot be fitted in the tank, Chatterjee, a deputy general manager in the company he joined in 1987, said. Any device to be designed by the team had to be small and access energy conveniently. The device ensures continuous air-flow, through tubes, to a special costume that keeps body temperature hovering between 18 and 22 degrees Celsius. This will now protect the gunners from fatigue.
The Mecon team has also developed a pair of battery-operated gloves and socks for soldiers camping at high altitudes and in severe cold. They are yet to undergo field tests, though.
But Chatterjee exuded confidence that they would function in Siachen, where the field tests are likely to be conducted. -

I am puzzled, since its that hot then why isn't an air conditioner (which many tanks already have) unsuitable and a small cooling device suitable?
The SM1 is very cramped and hot especially when engine is off. This is due to the hot and humid climate here in Singapore and the thick fire retardant coveralls which we wore. We are sweating very heavily! I really can't imagine being in a tank out in the desert where its very hot in the day and freezing at night! -

But if you cannot accept some well-known facts or criticisms discussed here eg that the Arjun has a weight problem (which was made known in established military mag eg Janes) please do not let your 'patriotic Indian sentiments' cloud/deflect the issue/criticisms here. Most of us, I believe, have no access to these new Indian military hardware gems and therefore, the points raised are based on what we read in mags.
I believe the Arjun tank is a wonderful piece of equipment produced by Indian ingenuity but perhaps it is too ambitious for a 1st-timer in tank design/production. As discussed in another thread on the LCA http://www.sgforums.com/?action=thread_display&thread_id=188083 , and given the environment where the Arjun will operate (Indian subcontinent) & face Pakistanis/PLA's tank force, the Arjun is nothin if it cannot hold its own & defeat the proliferation of Chinese-made tanks by your ....you know who .
P/s Food for thought, do you ever wonder why the Indian Army procured Russia's ultra modern T-90 tanks? If you have the answer to that, you will perhaps know the base where the criticisms that is leveled against the Arjun here.
