Re: Armoured Vehicles Discussion Thread
Is RoI on R&D that is added for 428 of them for 8m each? In that case, it would be more., cause we did take sometime to come up. But as more orders takes place, say 1000 tanks at the min, then it can come down to 4m/5m. But then again, who is me marketing this. Perhaps GoI has already lined up external customers for 8M, then it is a fair game.

Re: Armoured Vehicles Discussion Thread
To protect the driver in case of mine blasts I think. This kind of thing is standard design practice in mine proof vehicles . Sort of like driver's seat suspended from the roof, rather than bolted/welded to the floor.roof mounted drivers seat - is this for the jernails to take a ride?

Re: Armoured Vehicles Discussion Thread
oh ok...I thought it was a separate chair welded to the roof of the turret !
Re: Armoured Vehicles Discussion Thread
Even some tin can series incorporated the suspended from roof drivers seat. Thsi way the mine blast shock wave will not crumple body.

Re: Armoured Vehicles Discussion Thread
Slight correction - General sahab is standing on the radio-operator's/loaders seat. The gunner sits ahead and at a level below the commander's position. You need to go down further from the commander's seat to reach gunners position.Austin wrote: <SNIP> But seriously IIRC when Arjun was first accepted in the army during PV Narasimha Rao time he was standing inside the commander seat and even Gen Shankar Chaudhary was similarly standing in gunner seat

The counter arguments based on your explanation would be, Why have a GSQR to begin with? if an imported item is not bought because it meets the GSQR, but because it is the best available. I am sure their would have been products which met the GSQR, as spelled out by the IA, why not buy one of them.
Alternatively, if a product meeting GSQR is not available due to political reasons and the product available is not meeting the GSQR, then why not provide that opportunity to a domestic product. That is being provided to an imported product. As the way it is, IA requirements that have been spelled out for a particular product are not being met by an import.
Re: Armoured Vehicles Discussion Thread
Talking about ammunition, AFAIK, DRDO had plans to develop/integrate the following types of rounds for Arjun MBT (DRDO Tech Focus 2002 - Ammunition System): (1) APFSDS, and (2) HESH. Then there were talks about additional rounds: (1) HEAT, (2) HE, (3) Anti-Helicopter Round, and (4) Israeli LAHAT missile. We know that LAHAT has been integrated, and possibly HEAT/HE rounds as well. Wondering what that "additional ammunition" is? It could be Israeli 120mm APAM-MP-T, M329 Cartridge (Anti-Personnel/Anti-Materiel, Multi-Purpose Tank Cartridge) since it serves as an anti-helo round as well.sameer_shelavale wrote:Upcoming modifications on the Arjun Mark IIcolonel sahab has posted next article on Arjun MK2.here is the list of 19 major modifications that the Arjun Mark II will feature.

What would a typical round types carried (totaling 39 rounds) on a Arjun MBT? Here's my guess:
- 4 x LAHAT -> long-range (8km) anti-tank/anti-helo ammunition
- 5 x HESH -> secondary ammunition against a variety of soft targets, tanks/LAVs, fortifications
- 5 x HE/APAM -> secondary ammunition against infantry/anti-tank squads, soft targets, LAVs, fortifications
- 25 x APFSDS -> primary anti-tank ammunition
- 1 x LAHAT
- 1 x HESH
- 1 x HE/APAM
- 7 x APFSDS
Re: Armoured Vehicles Discussion Thread
question on blast off panel and roof mounted driver seat.. do these features have some common goal in terms of modularity and protection/affordance?
Re: Armoured Vehicles Discussion Thread
Large orders can make Arjun tank cheaper.
The army could clear the indigenous Arjun Mark II main battle tank (MBT) for frontline service after trials next year, but a question mark hangs over the Arjun’s prohibitive cost. Heavy Vehicle Factory, Avadi (HVF) has already built 124 Arjun Mark I tanks for the army at Rs 18 crore per tank. But on 29th August, Defence Minister AK Antony sprung a bombshell when he announced in Parliament that, “The likely estimated (sic) cost of each MBT Arjun Mark-II… will be approximately Rs 37 crore.”
This is twice the price of the Russian T-90 and not much cheaper than USA’s M1 Abrams, the world’s most advanced MBT. On 1st July 11, the US Congress was notified that Egypt would buy 125 Abrams tanks for $1.3 billion — i.e. $10.4 million, or Rs 54 crore, per tank.
During a visit to HVF and to the Central Vehicles R&D Establishment (CVRDE), which has developed the Arjun, Business Standard was explained that the cost of the Arjun is easily reduced. If the army places a larger order the price will drop by 30 per cent.
P Sivakumar, Director of CVRDE, explains that 50 per cent of the cost of the Arjun Mark I went on three imported components —the gunner’s main sight (GMS) from OIP Systems, Belgium; the gun control equipment (GCE) from Bosch, Germany; and the power pack (engine and transmission) from Renk, Germany — which together cost Rs 12 crore. Ordering just 124 pieces left little leeway to beat down that price.
“If you are talking just 124 tanks, there is a problem. Bring an order for 500 tanks. We will go for ToT (transfer of technology) for the foreign parts… The cost of labour in Germany is the highest in the world. We will build 70 per cent cheaper in India. If we buy the power pack of the Arjun for Rs 7.5 crore on Friday… I will produce it in India for just Rs 4-5 crore,” says Sivakumar.
For an army with more than 3,500 tanks, including 2,400 obsolescent T-72s that are crying out for replacement, ordering just 124 Arjun Mark IIs seems unduly cautious. But the army has little incentive to reduce cost. Though the generals are now willing to order more Arjuns, they are placing their orders piecemeal.
Since most of the Arjun’s 10,000 components are outsourced, the size of the order is a crucial determinant of what price they are supplied at. Says RK Jain, Additional DG of the Ordnance Factory Board (OFB) who oversees HVF: “If the army’s indent is for just 124 tanks, the vendors charge higher prices. Besides, the amortisation cost of jigs, tools and equipment is reduced over a larger order. HVF and CVRDE have been jointly requesting the army to confirm an order of at least 250 Arjun Mark IIs so that we can negotiate from a stronger position,” says Jain.
Another reason for the Arjun Mark II’s rising cost becomes obvious at the Arjun production line at HVF, where the army is collecting the last of 124 Arjuns that were cleared for production in 2008. Just as the Rs 50 crore Arjun line has hit its stride, it must shut down for at least two years since another order can come only after the Arjun Mark II trials next year.
I walk through the giant workshop, now almost empty, with the HVF manager who oversees Arjun production, HR Dixit. “Even if the army clears the Arjun Mark II next summer, and indents for 124 more tanks by October 2012 (an optimistic time-frame), we require at least 12 months for obtaining the items that go into the Arjun. So end-2013 is the earliest that the Arjun assembly line can restart,” says Dixit.
The skilled workers on the Arjun line, who have developed invaluable expertise while building 124 Arjun tanks, will be distributed to other parts of HVF, Dixit tells me.
“We can send our workers to HVF’s other lines. But what can we do about the dislocation of our sub-contractors, many of them small enterprises around Chennai, who supply thousands of Arjun components like fuel pipes and bearings. They will seek other work because they know they will get no orders until an indent is placed for the Arjun Mk II. And, when we need them again, they might not be available,” says Ashutosh Kumar, works manager.

Re: Armoured Vehicles Discussion Thread
I think IA should bump up the order to 1000 tanks at $5-6M each. going by bharat pack, and 90% indigenous parts of mk 2.
Re: Armoured Vehicles Discussion Thread
Piece meal orders are meant to kill Arjun. Compare with Tin Box orders of 1600+
Re: Armoured Vehicles Discussion Thread
We should be greatfull that the IA has at least given orders for 248 tanks.

Re: Armoured Vehicles Discussion Thread
The problem is with MoD... once they say it is proven, then like it or not, the numbers are given to maintain the production standards, quality and cost. PERIOD. They can call it whatever they want.. They will never get a chance to call it kickback* etc. no chance here. The product itself should be a terror to chase away competition. Good Job Arjun! go for the kill!
now thinking about Ferrari idiom, I feel there is a link here.. may be the designer indirectly pointed that Arjun can kill those Ferrari seekers rather. correlation of tfta pedigree.

Re: Armoured Vehicles Discussion Thread
Just a blinked on reading your explanation. What is weight of ERA package in T-90s? I'm sure it is quite heavier than 1.5t. Arjun turret is much bigger in size compared to T-90.

That much is clear, but the question remains, if a 60 ton tank needs 1.5 tons of extra ERA and blow off armour panels to meet the IA GSQR. Then, what does it says about the tin can and the fact that 1600 + of those have been ordered to be built. <SNIP>
On the ERA front - I have a feeling that we're going the western route in terms of their response to superiority of Soviets in numbers. Basically, heavy well guarded tanks which can take multiple hits and with overmatch in terms of sensors and electronics. Arjuns, after all, are going to spearhead the attack as part of IBG (my inference) and need to slog it out till the hammer of Strike Corps falls.

I predict 1200 Arjuns (124 Mk 1). estimate is that it will reach MK 5. Rest will be a mix of T-90 and probably a lighter tank.

I am sure such a video will do great damage to the IA. Many afsars will most probably be sacked for their choice of tin can and especially its ordering in such large numbers.

The Mk2 is a welcome development and looks like they will be following an evolutionary path to the FMBT, and an Arjun Mk6 is simply called FMBT like they did with the A2P renamed as A4, so between Mk3 and Mk6, all the requirements of a FMBT are realized?chackojoseph wrote:I predict 1200 Arjuns (124 Mk 1). estimate is that it will reach MK 5.

On a different development path, there was news about collaboration with poland on a ultra light tank transportable by heli, probably heavy lift choppers, anyways since weight is at a premium, would they be adding a Ti based turret and gun a la M777 (4 tons), a gas turbine engine say the engine meant for LUH (1 ton) and finally an all composite hull (?)
On the howitzers, why don't they mothball the T-72's while they have some life left and when a local howitzer is ready, they could retrofit them onto these hulls on the lines of Bhim, the mothballed T-72's could be replaced by Arjun in quick time

Answered above on mark's. Even with mark-2 deployment, there will be incremental refinements as user uses is and FMBT shapes. We might see FMBT tech incrementally being used. When they were trying to push MK-1, mk-2 was already being incrementally tested. Some of you can work on exact figure that can be rounded to 1200 tanks based on the number of a tanks in a unit/brigade etc.
I firmly believe that DRDO's aim of 500 tanks (for Mk-2) for break even will be outpaced.
On the AS style treatment.... I have been there, done that.....
Re: Armoured Vehicles Discussion Thread
True insight! Most of the tech developed for the Arjun series will eventually find its way onto the FMBT, albiet in more advanced versions.chackojoseph wrote:...

Looking at the timeline, IA is looking to field the first FMBT between 2020 and 2025 timeframe. That gives another 10 to 15 years to develop Arjun MBT further. IMO, Arjun Mk.3/4/5 will realize these technologies:
- indigenous power pack (1500hp engine and transmission)
- indigenous gunner’s main sight (GMS)
- indigenous gun control equipment (GCE)
- improved integrated defensive sub-systems
- improved battle management system (BMS) and communications that are linked to the larger network and other tanks in formation
- improved sensors and situational awareness for the commander, gunner and driver
- improved protection through new generation of Kanchan armor and ERA/NERA add on armor
- reduction in overall weight using lighter weight composite armor in selected areas
- improved crew comfort for operating in high desert temperatures
- improved ammunition - APFSDS, HESH, HE/HEAT, etc. ... maybe an indigenous AT missile replacing LAHAT
Possible quantities ordered to reach CJ's predicted numbers:
.124 x Arjun Mk.1 (2 regiments)
..............................124 x Arjun Mk.2 (2 regiments)
.....................................248 x Arjun Mk.2 (4 regiments)
....................................................................744 x Arjun Mk.3/4/5 (12 regiments)
Totals: 1,240 Arjun MBTs in 20 armored regiments

So, no new engine on MkII.Broadsword said...
Who has told you that the Arjun Mark II would be getting a new engine?
A new engine would require re-engineering of the kind that would delay the Mark II beyond acceptability.
Instead, the 1400 HP engine's output has been optimised by re-engineering the tank's final drive... and re-arranging the gear ratios so as to obtain more torque at lower speeds... and obtain fast acceleration, lower operating speeds and better fuel economy.

Nov. 2010 - The Hindu: 1,500-horsepower FMBT to replace T-72 tanks beyond 2020
The DRDO is launching a project to develop the transmission for the tank; the indigenous engine and transmission will together be called Bharat Power Pack and it will meet the FMBT's mobility requirements.
So they're aiming for more horse-power and two-thirds the volume in the first-generation of Indian design itself.The FMBT will weigh only 50 tonnes compared to Arjun-Mark II's 62 tonnes. The DRDO is simultaneously working on Arjun-Mark II. The volume occupied by the electronics package in the FMBT will be less. The FMBT's engine will be two-thirds the size of Arjun-Mark I's, but will generate 1,500 HP compared to Arjun-Mark I's 1,400 HP.

Lets hope that FMBT does not damage the arjun unless they can come up with a prototype or two.

Improving Arjun's already great suspension.
Ajai Shukla
One of the distinctive features of the Arjun tank is its hydro-pneumatic suspension, distinct from and far more advanced than the "torsion bar" arrangement that conventional MBTs (including the T-90) feature. The Arjun's suspension provides a smoother ride, making the tank a more stable gunnery platform that permits more accurate engagement of targets whilst on the move.
The Arjun Mark II features an enhanced version of the Arjun's well-proven hydro-pneumatic suspension, with the new one designed for a 70-tonne load. This is part of an improved "running gear", including the road wheel mountings, the road wheels, axle arms and shock absorbers.
The new suspension has already been tested in the recent trials and run for 1,300 kilometers. In order to obtain an accurate comparison with the earlier suspension, the trial tank was fitted with both: the old suspension on the left side and the new one on the right. The photographs --- in which the new suspension still looks new while the old suspension looks somewhat the worst for wear (not surprising; 1,300 km is a lot of running!) --- point to a successful upgrade.
The Arjun's suspension will be practically all-Indian. The road wheels, which continue to be built by Sundaram Industries, have been improved with better manufacturing and bonding processes for the rubber. Tractor Engineeers Ltd (TENGL), an L&T company, is doing parallel development of the Arjun track (imported so far), including development of one of the most difficult running gear technologies: the track pins.
I am amused at the many who appear to believe that the Arjun is "built entirely of foreign components" that are "hammered together in India". This kind of view is rooted in a deep lack of understanding of the processes of indigenisation. It is true that almost 60% of the cost of the Arjun goes on imported components. Practically all of that goes on just three components --- the power pack; the gunner's main sight (GMS); and the gun control equipment (GCE). Almost all the Arjun's other 10,000-odd component are sourced from Indian industry, which is rising to the challenge. More support from the government, in terms of better procurement procedures, would accelerate this.
There will be more on this particular issue in Broadsword. Stay tuned...
