Arjun Main Battle Tank (MBT) Mark II

[Kunal Biswas]

But, Sir the RCWS will be on commander side unlike in the vid its on Loader Side ..

Kunal sir it cant be put on that area on Mk-2.

 

[Kunal Biswas]

@sayareakd Sir, Long back we discussed about ERA of MK2, I think the extra plate at back of ERA is actually NERA, The same NERA tiles on front Armour over chassis, In that scene this is a very effective Dynamic protection, A combo of both Heavy ERA and NERA ..

 

[methos]

That's not technical possible. NERA needs slope in order to work.

It is just the end of the holding bracket for the ERA tiles...

Sir OFB make Russian T90S tank with ERA, DRDO could have borrowed that,

it would have saved weight but they didnt do that, means they want to further secure the tank.

Afaik, The defeat of HEAT rounds is due to the composition of the metal in that tile, Which make it bulg ..

The MK2 era is stright coming from K5 technology, Than in this case why not just bolt mount it like on T-90 ?

=====================

I am not making any fact, But giving my observation on the case ..

That's not technical possible. NERA needs slope in order to work.

IMO the DPA being discussed use a non-explosive mean to disrupt ERA working like an ERA-

Also from what we can see a T-90S style ERA was cheaper alternative with less weight on the tank- providing better cover to the lower part of turret-

 

[shuvo@y2k10]

the arjun era may look like kontact 5 but there is no indications that it is a reverse engineered copy since russians are very sensitive to ipr and drdo will faithfully honour the trade agreements.most likely it has a diffferent composition and is effective both against tandem heat as well as ke penetrators though i don't know whether the indegenous nera also has similar features.

Arjun MK II main battle tank may miss 2016 induction date | idrw.org

A key source in the Defence Research and Development Organisation (DRDO) said, the Israelis who customised the LAHAT (also a Hebrew word for 'incandescence') for firing from the 120 mm main gun of the Mark II variant, has gone back to the drawing boards for correcting the error.
The DRDO source said, 'This has delayed the induction of the tank a bit, but then we are telling the army that since the platform, the tank, is ready they can take it up, with the missile getting mated later.'
The tank itself has undergone about 89 major and minor 'improvements,' and still have a few unsolved issues which are decidedly 'minor' like changing the position of a light bulb or so.
The range of the LAHAT pay-load is about three-and-a-half kilometres on the plains and about two-and-a-half kilometres in the deserts.
LAHAT was originally developed 1992 by Israeli Aerospace Industries (IAI) for firing from their own Merkava MBT. With a diametre of about 105 mm, the anti-tank can be independently targeted or targeted through laser designation. The latter means an alternative platform can illuminate the target with the anti-tank guided missile (ATGM) homing in on the laser spot.
Till now the army has ordered 124 Mark IIs, while the DRDO is still attempting to get the army raise the demand to 500, which the DRDO source said, would make the production line viable.
Though the improvements sought by the army has increased the weight of the tank – from about 45 tonnes to 67 tonnes. It can still pivot by 360 degrees while firing. The crew comfort is considered to be of a very high order, beating the T-90 Russian MBT hollow, sources say.
Now the DRDO claims it is for the army to make up its whether it wishes to field it by 2016 or wait for the LAHAT to come online fully, before it accepts the ready for deployment MBT.

Um, Not sure if this is the right time to join the conversation but the question is,
What exactly did they had to improve?

Armament

The Arjun MBT is equipped with an indigenousy developed 120mm main rifled gun with fin stabilized Armour-piercing discarding sabot (FSAPDS) and high-explosive squash head (HESH) ammunition. An anti-personnel 7.62mm coaxial machine gun is fitted alongside the main gun and a 12.7mm machine gun is fitted at the top of the turret to aim aircraft and ground targets. An anti-helicopter round is also being developed to combat air threat to armour.
The tank has special containers to carry 39 projectiles of 120mm ammunition. These containers keep the ammunition away from the crew, providing an additional level of survivability. The rear-side faces of the turret are fitted with up to 12 smoke grenade dischargers. The weapon systems can be operated in silent watch mode with the help of an auxiliary power unit.

Arjun self-protection

The newly developed Kanchan modular composite armour gives all-round protection to the tank from anti-tank ammunition. Kanchan has been manufactured by Defense Metallurgical Research Laboratory (DMRL) armour design and development division.
The armour is made of composite panels sandwiched between rolled homogeneous armour (RHA), which can defeat APFDS or HEAT rounds. The turret houses lightweight compact Kanchan armour. An option is also available to add explosive reactive armour. Mobile camouflaging system (MCS) technology is also being developed by the DRDO in collaboration with Barracuda Camouflaging Limited.

Fire control and observation

The Arjun is equipped with a computer-controlled integrated fire control system with a laser range finder. The system is jointly developed by BEL and IRDE. The day/ night stabilized sighting system is also incorporated in the system. The targets are hit with high first-round-hit probability and reduced reaction time. The system is capable of acquiring targets under all weather conditions, and the stabilisation system allows the main armament to accurately fire at targets on the move.
The gunner's main sight includes a day sight, thermal sight, a laser range finder and a stabilized head. Night vision facility is provided by a thermal imagery. The gunner and the commander can locate target in total darkness and in the presence of smoke, fog, snow, haze and dust. Targets can be found accurately with the laser range finder integrated on the main sight.
The panoramic sight allows commanders to have all-round surveillance on the battlefield without being disturbed by turret motion. The two axes rate gyro-mounted on the platform of the head mirror stabilize the view of the field, offering dual magnification.

Battle management system

The battlefield management system of the tank has been developed by the DRDO and Ebit Israel. The system connects the tank to other fighting units in the battle field. It is also equipped with GPS-based navigation systems.
Upgrades to the tank under development include a laser warning control system (LWCS), a tank urban survival kit (aerosol smoke grenade system, IR jammer and laser warning) and tank simulators.


Sounds like a perfect tank to count on during war. The only thing i could come up with was a better engine with more horsepower. That's about it

[sayareakd]

The Arjun MK II main battle tank (MBT) for the Indian Army may get delayed further than its pre-fixed 2016 induction date. Reason: Its Israeli Laser Homing Anti-Tank (LAHAT) guided missile has failed about 20 per cent of the times it was fired during last summer.

Arjun MK II main battle tank may miss 2016 induction date

How many times they have tested LAHAT ?

 

[maomao]

With so much of corruption and middle men infused by secular con-gress and their affiliated families of dilli durbar ; I believe, an indigenous product will never get inducted into armed forces.....and to top it up we have a Hijda shameless PM and moron of a RM!

 

[arnabmit]

@Kunal Biswas Dada, last I heard a year back was that ICL-20 syntheses process is so very expensive that it was unsuitable for mass production. Has there been any progress in this field?

 

[Kunal Biswas]

MADE IN INDIA-Arjun MBT Special Program


=============================
English

First two minutes (intro): Guy says he's speaking from the CVRDE campus in Avadi on Republic Day. He says Avadi stands for Armored Vehicle and Ammunition Depot of India, a fact he only found out that day. Then he says we will talk about this tank and all the matters behind it. Mentions commander, driver, gunner and he's going to talk to many people behind this tank.

1:55 First he talks about the Arjun Mark II engine at the Engine Test House. Dept. head of this area is Mr. Swaminathan, Engineers Karthikeyan and Muninathan. Mr. Swaminathan says the engine is 1400 HP, about 10 times the power produced by a car or a truck engine. For a 60 ton MBT, it can take it about 70 kmph on normal roads. He says in this area, they do quality control of the engine. Each engine does 40 hours here, of initialization test, followed by performance test and then endurance test. They test for full power, look for problems, leakage etc. here, after which the engine is fitted into the tank.

Every tank engine does 40 hours here. He breaks it down as first 7 hours, they do initialization and tuneup. Once that is done, performance testing is done for the next 23 hours, after that the remaining 10 hours is endurance testing. He says, engine weight is 6.3 tons, including both the engine and the transmission combined (i.e. total power pack). He says that the engine and transmission are fitted as one unit.

He then mentions the crane and talks about using it for high-temperature/low-temperature air intake testing and says after this, the engine goes for assembly/

5:45 - He's talking to Mr. Balaguru, a scientist in charge of design and development. Mr. Balaguru says that compared to Mark-I variant, this one has 89 improvements to it. Of these, 19 are major improvements and 70 are minor improvements. Then he talks about the mine plough that attaches to the front and keeps the tracks safe from buried mines. Then he talks about the ERA in front and explains that ERA = Explosive Reactive Armor. He says that if an enemy tank launches missiles or HEAT warhead (shaped charge), which have excessive penetration, this ERA armor helps neutralize them, which is a major improvement. Then he talks about the CPS (Commander's Panoramic Sight) on top. Commander can use at night or dawn and can use it to engage an enemy tank or designate it for gunner. This feature is called Hunter-Killer capability and is built in. He says it has a 2 to 2.5 km optimum range to inflict max. damage. It has missile capability to engage enemy at longer ranges. He says it can neutralize enemy tanks at 5 km. ranges because of the missile firing capability. Then he talks about the Laser Warning systems. He explains that enemy troops will paint a tank with a laser to find out range, before firing (Laser Range Finder or LRF). They use it either to designate or determine target distance or use it for a beam-riding weapon. The laser warning system detects their laser and figures out the angle it is coming from. On top of that, there is a rotary grenade launcher that creates a smoke screen in front of the tank, so enemy laser cannot be used as a guidance for the missile and in that time, it gives the tank a chance of scoot off elsewhere. Then he talks about the remote control weapon station. He says in the Mark I system, they have a gun for aerial targets + against human targets at longer ranges. The difference between Mark I and Mark II is that in Mark I, the loader has to come out of the tank to fire it, whereas in Mark II, they can acquire target and fire from inside and no need to come out. He says one more major improvement is that despite ERA and mine plough, vehicle weight of Mark II is only 4 tons more than Mark I. He says final drive that drives the tracks is also improved here for more torque. Also says that when driving in loose sand or rough terrain, if the driver is inexperienced, there is tendency for track shedding, therefore these tracks are designed for increased wall weight, so it can be used even by inexperienced drivers without causing track shedding. He also says that since the tank is in a different weight class than Mark I, the hydro suspension is redesigned and it is indigenous and CVRDE made. Reporter asks how many team members are involved in building a tank. Mr. Balaguru agrees it is team work, but says he can't reveal how many. He also says one more big thing about this is that the improvements were all done within 2 years from start to handing for user trials.

11:30 Talking to Program Manager Mr. V. Balamurugan (Caption says he's managing director). He also mentions that there are 89 improvements and done in 2 years from 2010 to 2012. He says CVRDE has 12 different design divisions, each one does its part in the final assembly. He says that aside from these 12 divisions, DRDO has 6 other establishments that also contribute parts to the tank. He says his role is to coordinate these 12 divisions + 6 drdo labs. He says tank has number of stakeholders: army, DGSE, production agency etc. He says they involved all of them very early on in the design stages and got technology transfers done (apparently his job) and got necessary workers etc. did several meetings and figured out how to manage the program up front. He says tank did trial run and says something like 1000+ KM (didn't catch exact number except for 1000 part). He says they discussed what trial activity would be done to the tank and he mentions there are more trials coming. He says after trials comes production, and with production comes making sure the needed facilities in production agency are set up and ready, by the time the Army accepts the tank. In other words he makes sure that there is no delay between development acceptance and production stage. He says they are working on it and have drawings and documentation prepared for the user (EME). He says that it will take 3 years (i.e. 36 months) to produce the tank, but maintenance life is 30 years. So for it to be maintained for 30 years, they do all the planning up front, so that when the tank is released, the maintenance stuff is already planned for.

14:45 - He talks about the person in charge of the running gear, Mr. Solomon. Mr. Solomon says that the tank does not only run on roads, but is a cross-country vehicle. Country has desert terrain, river terrain, dunes, mountain terrain. He says this tank has to negotiate all kinds of terrain, so running gear is a very important system. He says the track is a chain rubberized track. He says that when the tank is running on a road, it should not ruin the road, but it should also be flexible when going cross-country. He says to do this, the suspension is a very special system. He says that this is the first time in India that this is 100% indigenous system made in India, design, development etc. He says it is a hydro-gas suspension system, has nitrogen gas and oil in the shock absorber. He says wheels are solid rubber and wheel can travel 537 mm. total and this helps negotiate all terrains. If this running gear system was not there, it could not negotiate cross country terrain.

17:35 He's in the simulator operating area. He says that in very simple terms, a simulator is sort of like a video game. He says that for example, it is not possible to drive in F1 race, but we can sit at home and play something that feels somewhat like it. He says that this is a simple simulation, but Arjun Mark II simulator is bit more realistic, controls are like interior of tank, how gunner shoots, how commander operates, all can be done inside.

Person in charge of simulator says that you get all the vibration and feeling of driving a real tank in operation -- whatever disturbances you feel in real life, you will feel inside the simulator. Can also simulate different environments -- fog, dust, storm effects, evening conditions. Drivers can practise in varied conditions. They learn how to start it, how to stop it, what procedures to do in emergency situations etc.

Then they go driving and the reporter points to a simulated cement block in the distance. When they get to it and climb it, he says it feels like climbing the real thing. Next, coming up is a big gap between two cement blocks. He gets to feel how it feels and points that viewers can see the screen also moves as though the gap is real.

Next he talks about simulating night vision. Guy points out that in wartime conditions, they don't use headlights. He says enemy can tell where they are if they use headlights, that's why they use Passive Night Vision Device (PNVD). He says that if you're looking outside in the dark, you cannot see anything, but the driver can see much more through his display upto 50 meters. Guy says only driver can see it, so reporter asks what about gunner. Guy says gunner has his own thermal effects sight. Commander also has his own sight. He repeats that driver's sight is much better than what someone outside with naked eye can see.

Next reporter talks about firing conditions and mentions that the simulator vibrates realistically as though a real gun is fired. Next is fording exercise - i.e. how to go into water obstacle and outside it.
Reporter goes into little more recap and then thanks Mr. Anbazhagan (chap in camo uniform).

23:30 He's going to talk to CVRDE director Mr. P. Shivakumar. Dr. Shivakumar explains CVRDE = Combat Vehicle Research and Development Establishment. He says Ministry of Defence takes care of all services, Army, Navy, AF. Then we have DRDO - Defence Research Development Organization. Then there are other labs, of which one is CVRDE. CVRDE role is only combat vehicles. Of these combat vehicles, CVRDE is mainly responsible for tracked vehicles. He explains car, bus, etc. are wheeled vehicle and tanks are tracked vehicle and can do all terrains. He says CVRDE was originally there to support the Heavy Vehicles Factory, but now they participate in many products for Army, artillery, air force, navy etc. Main product here is Arjun MBT and he says earlier tanks were imported, or for tanks like vijayanta, T-72 it was just transfer of technology. However, he says today, Arjun, we are proud to say, it is made in India and used by us. It is the first of its kind, made for India's requirements, for indian terrain. He points out that if you look at T-series tanks, they are built for Russia's needs, not India's. He says, if you look today, Arjun Mark I has two regiments. He says they have 45 tanks per regiment, so there are 90 tanks fully functional in there and total of 120 tanks produced. He mentions comparative trials between Arjun and T-90. He says Army was very happy with tank. He points to Mark I on right and Mark II on left and says that it took 30 years for Mark I, but only 2 years for Mark II. He says DRDO has 4 labs and of these, CVRDE only takes responsiblity for tracked vehicles and don't do mini or micro vehicles. He says Army didn't say we want X technologies, but they looked at what was available around the world and saw what was needed for India and there was need for something for low-intensity conflict. He said, big factor in low-intensity conflict are mines. He points out how many CRPF people are killed, so mine reduction is big, so they developed a vehicle for mine reduction. Another matter is surveillance, he says something about if you look in Thiruvanmalai now, there's a UAV flying above. Third factor is Nuclear-Biological-Chemical threat. If you look at all these factors, Army has some old BMP-2 infantry tanks which they modified from manned operation to tele-operation. He says that tele-operation means that they can sit in a base vehicle and operate through camera from distance of 5 km., which they have fully proven. Now they've improved that to 20 km. distance. First they want to prove tele-operation at 20 km. and then want to go for fully autonomous vehicle. Fully autonomous means no need for human operator. He says with tele-op you can protect an island, operate the UGVs from the center.

Then talks about mine reduction. He says that they have a vehicle driving with sensors in front. He mentions that one sensor technology is not enough and so they have to use 2-3 different technologies sensors that work together to ID a mine. After they ID and mark the mine, they have to remove it.

Reporter asks if Mark II is 100% indigenous or are there any outside parts. Dr. Sivakumar says that no country uses 100% indigenous tech. He also says that when you look at numbers, even though cars are produced in lakhs, they are still importing stuff because we can't do it all ourselves. So what they are doing is first see what is already available in India or can be produced in short time and whether there is industrial support. Then he says they were given 89 improvements of which 19 are major and says that to develop the tech for these takes 4-5 years. So based on that, they decide what to import and says they can't just import anything arbitrarily, but should get proven technologies. So they decide what to import and what is made indigenously. Now if you look in Mark II, there are several new technologies, one is missile firing capability. Without that, your loader has to come out to fire at threats, but Mark II has RCW (Remote Control Weapon System). Then he mentions the laser warning system and the smoke grenades that form a screen to hide the tank. He mentions the ERA armor and chemical threats. He says in these technologies, we've done a lot ourselves. He says there are big differences in suspension between Mark I and Mark II, because of difference in weight category and they had 20 years to iron out all the problems. He says with the Mark I, if the driver were to steer it on the side of the mountain without knowing about how to negotiate it properly (e.g. not angle the stick right), it is possible to detach the track. In order to avoid that human error factor, they've redesigned tracks in Mark II. Then he talks about cost of production of tanks. Dr. Sivakumar says currently Mark-I costs about Rs. 24 or 25 crores. They haven't estimated or negotiated cost of Mark II yet, only dev. expenses for the prototypes have been around 140 crores. He says right now, 30% of the cost is going out in foreign exchange. However, he points out that if you make 1000 tanks or 1100 tanks, then you can see cost advantage and the unit cost will drop drastically. They can decide cost only after they know how many tanks to make.

Then reporter asks how they test how everything in the tank works. Dr. Sivakumar says that during development & production, they can only do limited trials in Avadi, because Avadi doesn't have all terrains to test with. They test the automotive side (i.e.) how it performs on flat surfaces, then test against gradients, obstacle clearance, side slope etc. But you have to consider where the tank is being used. For instance, Arjun is needed in the border, where there are desert conditions. And in those conditions, temperature goes to 55 celsius in summer. So they do limited testing in Chennai and then transport it 2500 kms. to the border, which takes 20-25 days. When it gets there, there are two important areas. One is mahajan? (marasan? couldn't hear it exactly) and other is pokhran. These are firing range areas. In those areas, there is loose sand and dunes and high temperature. One more thing with the sand particles is that they are as fine as talcum powder. Here they test the engine air filter capability, cooling system capability etc. So they take them there and do two types of trials: First is automotive trials, how does it handle gradients, desert, loose sand, sand dune, hard sand etc. which we test to satisfaction. Then there is firing test, whether with small arm or main gun, they fire it first. They make sure it performs to the requirements and after doing these trials, it is handed to user. As far as user is concerned, when they go to trial, they are given a set of trial directives and they test how everything works: track, firing, electrical, suspension, sights etc. full trials With Mark II they started trials in July 1st to August 2013 and did over a year worth of trials and tested every subsystem. Mark II logged over 3700 km in the Army's own range + the 2000 km in Avadi's range for a grand total of 5700 km. Then he talks about the missiles and the tank armaments. Main gun is 120 mm. rifled bore, which they check for 2 to 2.5 km. ranges, also testing at night and when tank is static or when tank is moving or when enemy target is static, all scenarios are tested for firing purposes. For missile testing they do them at min. range of 5 km. at least, though he says it can do 6+ km. They've tested with 22 missiles.

Final question reporter asks is if CVRDE is only making tanks for India or are there plans to export to some other countries. Dr. Sivakumar says there have been enquiries from other countries, but India's MoD has to take the decision to export.

1400hp MTU engine has better torque for quick acceleration, Which is essential in battlefield than top speed ..

1400hp engine is no disadvantage but an advantage ..

I don't know how you came to this conclusion, but the MB 838 engine used in the Arjun doesn't have more torque than the 1,500 hp engines from MTU and competitors.

@methos, Its not first time you make such points,

1. I am not comparing engines but you .

2. MK2 Turbo charged 1400hp engine is modified to produce more torque at cost of losing few Kms in top speed ..

Do i need to repeat same lines again and again, Kindly Follow the thread before making questions ..

Thank you ..
