Finally some figures for MBTs.In a report about the improved Arjun still waiting for IA orders, the costs of T-90s (28cr. ) and Arjun (37cr.) are given.This apart from weight ( 68t) is probably why the IA keps preferring T-90s. More numbers at lesser cos,approx.25% cheaper a pop. With 480+ more T-90s on order in kit form and budget woes,emphasis on increasing the arty. numbers with desi built types,the future of A-1A/2 looks bleak.

The need for better ICVs is long pending.One can't understand why there has been little movement on this subject as some desi models too have been unveiled. The Rus are even moving from BMP-3s to the new Armata T-15. Upgrading old Sov. era ICVs is only an interim job,the IA needs a new design plus a light tank for the mountains.

So T90 with 1600+ in numbers is only 25% cheaper than a heavily upgraded and only 125 Arjun?

Given that the T-90s (best of the best) sent to the Tank biathlon couldn't even complete the course, leave alone compete for top 3 positions, 25% is a small price to pay. And the more important weight parameter is ground pressure. Gross weight is used for crossing bridges - bridges don't fail the first time they are overloaded. Every civil engineering structure is designed with a factor of safety of at lease 2.0. Therefore, the gross weight would not cause problems in battle, it would be the savior for the crew inside (unlike the T-90). With its superior armor and ERA its amazing suspension and the ability to fire on the move, built in crew comfort, the Arjun would destroy a T-90 (like it did in trials).

The IAF is paying 4-6 time the price of a LCA for the Rafales, (2 times the price of a MKI) because of 0.5 gen advancement in tech. Here we have at least 1.0 gen advancement and the IA balks at 25% increase? And can we have a source for the price of the two machines please?

I have mentioned it before. DRDO should pull the rug out of this "weight" argument by making a 3 crew with autoloader version of Arjun.

The whole issue is Army has not asked for it and DRDO will not do it until Army asks for it. Chicken and Egg.

Since DRDO is not a arms manufacturer, it cannot "suggest" technology.

DRDO - should provide the autoloader solution - just to put the IA in a pickle. This is not about weight or superiority of fighting capabilities. It stinks of what we all know very well - he who shall be unnamed. This was a good system to mass produce - flood copies in the world and generate well paying jobs. Exactly why India is a paper tiger in manufacturing.

Not appropriate to compare T90 and Arjun's costs. One is an investment in another country's MIC while the other is an investment in our own MIC.

Help me understand something. Why isn't Arjun primed for Exports?

Yes, I know that if our own Army doesn't buy, why would someone else. But always worth trying. Lets compete in the marketplace against Chally, Leopard, Abrams etc.

CHENNAI: It's the most lethal, sophisticated and all-weather battle tank that India has indigenously designed and conceptualised till date.

Meet Arjun 'Mk-1A' main battle tank, a 68-tonne rugged bull, waiting to join the Indian army and one of the star attractions at the 11th biennial edition of DefExpo India 2020 scheduled to be held in the Uttar Pradesh capital of Lucknow in February.

Armoured Corps has cleared the tank after successful completion of the final integration tests conducted earlier this year in the western sector of Rajasthan. Arjun Mk-1A is an improved variant of Arjun Mk-1, whose two regiments (124 tanks) are currently in service.

Scientists of Chennai-based Combat Vehicles Research and Development Establishment (CVRDE), a laboratory of the Defence Research and Development Organisation (DRDO), are the architects of this improved avatar of Arjun and the Heavy Vehicles Factory (HVF) in Avadi is soon expected to commence production after receiving the order.

Top DRDO officials confirmed to Express that the new variant of Arjun had passed the rigorous army evaluation.

"The tank has fulfilled all user specifications and undergone elaborate field trials. We expect the order of intent any time soon."

Officials said 72 improvements were made to Arjun MBT Mk-1A over the existing version, of which 14 were major upgrades that were specifically requested by the army.

CVRDE Director V Balamurugan told Express the fundamental parameters of a battle tank are "fire power, protection and mobility". Arjun MBT Mk-1A has been improved on all these fronts.

Under firepower segment, four upgrades have been made. An improved Gunner's Main Sight (GMS) integrated with Automatic Target Tracking (ATT) has been fitted, which helps the crew to track moving target automatically making it easy for the gunner to fire even when the tank is on the move.

The Commander's Panoramic Sight (CPS Mk II) has been integrated with Thermal Imager that enables the commander to effectively conduct surveillance both in day and night through eye-safe Laser Range Finder with an advanced Hunter Killer Capability.

Besides, additional varieties of ammunition were incorporated to enhance the lethality of the enemy battle tank.

Other than conventional Fin Stabilised Armour Piercing Discarding Sabot (FSAPDS) and High Explosive Squash Head (HESH) ammunition, Thermo Baric (TB) and Penetration Cum Blast (PCB) ammunition have been developed.

Lastly, the vehicle was upgraded with a Remote Controlled Weapon Station that provides the loader the capability of engaging ground targets and aerial targets from the protective envelop of the tank armour. It also provides an additional capability to fight in urban area called Hatch-closed firing.

Extra protection for crew

The battle tank will have a crew of four -- commander, gunner, loader and driver. Keeping them out of harm's way is paramount. For this, Arjun Mk-1A comes with a slew of new features.

Balamurugan said Track Width Mine Plough (TWMP) is a significant addition which provides capability for the battle tank to cross minefields with ease as the plough mounted to the front of the vehicle creates a mine-free path by ploughing through mines and throwing them to the sides of the tank.

The Explosive Reactive Armour (ERA) panels are provided for effective protection against the ever-evolving anti-tank threats like shoulder-fired anti-tank grenades and missiles. These panels have been mounted along the frontal arc of the hull and the turret.

Another key feature added is a Containerised Ammunition Bin with Individual Shutter (CABIS) that gives crew enhanced protection from inadvertent burning of ammunition stored in the ready round bin.

The hot gases generated due to ammunition burning is vented out by blow-off panels from the roof of the turret, thus saving the crew.

Besides, Arjun Mk-1A has protection against chemical attacks. A special chemical sensor is mounted to detect the presence of harmful toxic chemicals in the atmosphere around the tank.

"The sensor detects the harmful chemicals, triggers an alarm and the Nuclear Chemical warfare system increases the pressure in the tank compartment to a little higher than in the atmosphere thus preventing toxic air from entering the tank. The tank crew get air through a particulate filter for their survival," CVRDE official said.

The Roof Mounted Driver's Seat protects the driver from shocks and enhances driving comfort.

Other new upgrades include Laser Warning and Counter Measure System that protects the crew by creating a smokescreen between itself and the enemy and Anti Infra-Red / Anti Thermal Imaging paints that reduce the signature of the tank when viewed using an IR/TI camera or goggles making the tank difficult to be detected by enemies.

Mobility-related improvements

Officials told Express one of the challenges in making of Arjun MBT Mk-1A was the overall weight. Every improvement comes with baggage, which the user may not like as the mobility may be compromised.

To counter added weight, an Advanced Running Gear System has been developed where the hydro-pneumatic suspension system was completely redesigned to enhance agility of the Arjun MBT Mk-1A. Tweaking the final drive also ensured the required agility of the tank.

Meanwhile, an Advanced Land Navigation System is added to provide enhanced navigation capability of the tank in desert terrains during war.

It provides accurate information of where the tanks is using either Inertial Navigation or GPS or both and where the tank needs to go in the absence of any signage in the war theatre.

An uncooled Night Vision camera for driver has also been provided.

The earlier Image Intensifier (obsolete technology) for the tank driver has been replaced with a un-cooled Thermal imager with binocular sights for the driver thus providing him with a capability to travel at reasonable speeds even in pitch-dark conditions.

^Still based on a Tatra platform, I think. Reminds me of the cozy BEML-Tatra relationship that screwed IA through inflated prices. Hope that mess is sorted now or preferably, we can have the OEM make these tweaks and sell them directly to the IA.

While Arjun is thought to be desi,a large part of it is firang,why maintaining A-1 has had problems with some firang components difficult to source.Just 125 in number hasn't been enough to build up a strong desi supply chain.

25% difference in cost is huge.It also has the cost of one tanker less to look after for life. The Arjun from inception was heavily influenced by the German Leopard MBT.In fact isn't the engine same? The DRDO did have money to come out with " Tank- X".
It could've tried out a T-90 turret on an Arjun chassis too as an experiment. The IA's future req. has been stated to be a 3- crewed 50t + MBT in the style of the Armata T-14. A-2 at 68t with a 4- man crew is even heavier than A-1 and will cost even more. No wonder the IA is less than enthusiastic about it. Chief after chief has resisted pressure to buy Arjun. There must be some solid reasons for doing so.

Even if A-2 is ordered, the number will be small as the increase in arty.,is of top priority, that too entirely desi for all types barring the Korean K-9 Vajra but built at home by L&T .We are much better off than Pak in numbers and quality of MBTs,plus there is the req. for a light tank for the mountains and huge inventory of ICVs requiring both upgrades and one-for-one replacements.

The man has no shame and pride in India and her engineering feats. It is remarkable he is given carte blanche to rave against world-class Indian products not tin cans. Indians need to take pride in themselves and their designs.

Is there any other army/DGMF in the world which sabotages its own superior MBT like this ?

Delay in ordering Arjun tank underlines the army's reluctance to “Make in India”

Although “Make in India” has been the central motif of the on-going Defexpo 2020 in Lucknow, the army continues to block further purchases of the Arjun main battle tank (MBT), years after it has met all the army’s ever-increasing demands.

With the Defence R&D Organisation (DRDO) awaiting a long-cleared order for 118 Arjun MBTs, the ministry of defence (MoD) instead asked the Ordnance Factory Board (OFB) last November to build 464 Russian-origin T-90S tanks at the Heavy Vehicles Factory, Avadi (HVF). With each T-90 costing about Rs 28 crore, the order is worth an estimated Rs 13,000 crore.

The army continues to block the indigenous Arjun tank even though, in a comparative trial the army conducted in the Rajasthan desert in March 2010, the Arjun proved itself equal to, or better than, the Russian T-90.

In the trial, one squadron (14 tanks) of Arjuns was pitted against an equal number of T-90s. Top army generals who witnessed the trial admitted the Arjun performed superbly. Whether driving cross-country over rugged sand dunes; or accurately hitting targets with its powerful main gun; the Arjun established it was a tank to reckon with.

Yet, the army refused to order more Arjun tanks, beyond the 124 it had already inducted into service. Army insiders say there is an ingrained belief that Russian tanks are better than Indian ones.
However, it was officially stated that the 62.5-tonne Arjun was too heavy for roads and bridges along the Pakistan border, and too wide to be transported by train.

Under pressure from the MoD to order another 118 Arjuns, the army then demanded several capability enhancements in the tank to make it more effective. At a meeting of the MoD-led Arjun Steering Committee in 2010, the army demanded an improved version of the tank, which would be called the Arjun Mark 2.

The Arjun Mark 2 was required to have 83 capability enhancements, including 15 major and 68 minor changes. Incredibly, given the army’s complaint that the tank was too heavy, the new enhancements would make the tank heavier by another 6 tonnes.

These included the fitment on the tank of mine ploughs (1.6 tonnes extra), explosive reactive armour (1.5 tonnes), suspension improvements (one tonne) and another two tonnes in other areas. Having complained earlier that a 62.5 tonne Arjun tank was too heavy, the army signed off on a six-tonne weight increase to 68.5 tonnes.

In August 2011, the MoD announced it had “cleared the proposal for placement of indent for 124 MBT Arjun Mark 2”. It said each enhanced Arjun would cost Rs 37 crore and the first batch would roll out by 2015.

By June 2012, the DRDO offered the Arjun for trials with all the enhancements, except one: a cannon-launched guided missile (CLGM) the army wanted to fire through the Arjun’s main gun. The DRDO had sourced the Lahat CLGM from Israel, but that could strike targets between 2-5 kilometres (km) away. The army insisted on being able to strike targets as close as 1.2 km.

The DRDO pointed out that the Arjun’s powerful main gun had already proved its ability to destroy targets at ranges out to 2 km. But the army insisted the CLGM should be usable against targets 1.2 km away. So the DRDO began work on an indigenous CLGM to meet those specifications.

By 2015, a series of trials had validated the improvements the army demanded. Even the CLGM’s laser designator was tested and validated with Lahat missiles. The DRDO asked for production order, promising to develop and supply the missile on priority.

However, the army dilly-dallied for three years, until March 2018, when it was agreed that the next batch of Arjuns would be supplied without missile firing capability, which would follow up separately. This version would be designated Arjun Mark 1A.

After several months of delay, Arjun Mark 1A trials were held in December 2018 and the tank found fit in all respects. The army’s trial team recommended the Arjun Mark 1A be inducted into service.

Incredibly, more than a year later, the army has not yet placed an indent for 118 Arjun Mark 1A. It has raised numerous issues – including ammunition availability, non-availability of spares and low indigenous content – to successfully avoid placing an order.


Were an indent to be placed today, it would still take HVF about 36 months to start delivering completed Arjun tanks. The DRDO is confident it would develop the CLGM by then, so those 118 tanks will actually be Arjun Mark 2, with full CLGM capability.

Asked whether there was frustration over the lack of orders, DRDO chairman, Satheesh Reddy told Business Standard: “No, we cannot get frustrated. We are very positive. The user trials for the Mark 1A have been completed in December 2018 and we have even developed the ammunition now. I am sure that the Indian Army will soon be inducting the Arjun Mark 1A.”

The MoD can fix this very easily by flatly refusing to sign off on any more T-90 purchases or just tell the IA that they can either buy the Arjun or make do without more tanks. I have said this on other threads, this govt. needs to take the right decisions to promote Make in India or shut their mouths about Make in India, at least when it comes to Defence manufacturing and let things continue as they are.

Meanwhile, DRDO needs to stop allocating resources to this wild goose chase that is the neverending list of "improvements" that the Army wants with the Arjun. It is pointless.

When the army used different yard sticks to measure tanks during T90 and ARJUN, it became an open secret that army treats ARJUNA as a step child.
For example, they would not conduct tests in firing on move. Sometimes I feel may be paki army and Indian army have a agreement that they will not fire on each other's tanks while the tanks are moving.

:rotfl: :rotfl: , Like any other agreements they will also not keep this promise. Only fools will suffer, if we don’t learn from history.
