Give Arjun a fighting chance
Those of us who want to see India emerge as a nation that produces its own weapons to contemporary standards would be dismayed and even perturbed at reports that Arjun, the Main Battle Tank developed after three decades of sweat and toil, will be taken off production even before it started rolling out in decent numbers. Apparently, this proposal is because Arjun has failed to meet the expectations — never mind the moving goal posts were set by the Army itself all alo ng; and the Army is now looking for state-of-the-art requirements 20 years hence. This is a legitimate desire if there is no urgent need to replace the ageing fleet of T-55s and T-72s.
Going by past experience, even advanced countries take a decade or more to bring about truly path-breaking improvements in weapon platforms. After 13 years, T-95 is still a work in progress in Russia. If one has a measure of what is being attempted in shaping futuristic tanks, there are several areas — electro magnetic armour, unmanned turret, use of composites and lighter chassis, total missile launching facility and, more importantly, choosing invisibility over invincibility, all in their infancy in development.
Therefore, even those who are called upon to draw RFPs (Request For Proposal) will only be able to put together, as in old times, a mélange of promised and mostly untested systems, cut and pasted from glossy brochures from the aggressive arms merchants or a mere wish-list. We must consider our terrain and battle conditions and not opt for tanks just because they are from Russia or the US or appear exciting in a demo DVD.
Anyone who has followed the chequered history of Arjun’s development would most certainly confirm that the Army has been less than fair in its handling of issues arising out of inducting indigenous tanks and deploying them.
Under the teeth of opposition from the Army, though unarticulated in public, the then Defence Minister, Mr George Fernandes, authorised production of 124 numbers in March 2000 after satisfying himself that all production issues were settled and this batch of 124 could be delivered by 2003-2004, according to his statement in Parliament then.
Army’s Involvement In Development

Army, as is its wont, was not impressed with Arjun even at this stage although on all parameters such as horse power, speed, suspension, mobility, rifled barrel, imagers and communication sets, it was way ahead of the Soviet tanks that the Army is besotted with. The irony is that, through the years, in the development era of Arjun, Generals of the calibre of Gen Shankar Roy Choudhuri, who later went on to become Rajya Sabha MP, were involved as Project Heads, Chairmen and Members of Steering Committees. The Vice-Chief of Army staff was always associated with every step of the decision-making.
Yet, after ostensibly being satisfied according to averments made in public at the highest levels of Chief Of Staff, the Army insisted on testing the equipment repeatedly almost every winter and every summer, in every desert and every mountain, making each piece produced a prototype. The DRDO was will-nilly forced to commit itself to such procedures as would have been unimaginable to be imposed on any foreign supplier.
Contrast this with the case of the T-72 or T-90. The Soviets or Russians sent a few tanks for testing and the Army made up its mind in a matter of less than two or three years on quantity and variants, convinced the civilian bureaucracy and ordered hundreds of them at one go. It is not that T-72s or T-90s functioned without any technical glitches in operation and maintenance. Even now, T90s are reportedly yet to overcome the problem of losing accuracy due to overheating, although they were cleared after due desert trials.
T72s have had their share of snags such as bursting of barrels, inconsistent accuracy, heating of engines, faulty ammunition loading and so on. Their communication sets are still primitive.
The laser range finders had to be sent back to the manufacturer in bulk for rectification. Overall, all problems were satisfactorily resolved as everyone involved climbed the learning curve.
Parliamentary Committee Report
It was only a year ago, the 14th parliamentary report by the Ministry of Defence stated that, Arjun Tank Mark-II production will be taken up after the successful completion of the first order of 124 Arjun tanks. The same report stated that, “MBT Arjun is a 60-tonne class battle tank with state of the art opto-electronic power-packed control system, weapon management system and high performance suspension. It is a product unique in its class, specifically configured for the requirements of the Indian Army.
Unlike the T-90 tank, which was primarily built for Russian Armed Forces, adapted by the Indian Army for certain specific roles, this T-90 is a 50-tonne class vehicle which does not have some of the advanced features of MBT Arjun. But it is an improved system over T-72 tank.
However, it is important to know that MBT Arjun costs Rs 17.20 crore per system from the production line and is Rs 6-8 crore cheaper than its contemporary system in the West. It is understood that T-90 tank costs approximately Rs 12 crore and is yet to be indigenised.
MBT Arjun’s firing accuracy is far superior to the other two tanks. It has a second generation thermal imager and can engage targets at 2,500 meters. Its 1,400 hp engine ensures excellent mobility performance. It has capability to fire Laser Homing Anti Tank (LAHAT) missile from the barrel of the gun. Only T-90 tank has such capability. MBT Arjun has good export potential in the African countries due to its superior features vis-a-vis contemporary MBTs. (Table)
Arjun’s Woes
However, in May this year, in reply to a Parliament question, the Defence Minister informed that Arjun was found to have low accuracy, frequent break-down of power packs and problems with its gun barrel in the recent accelerated user-cum-reliability trials. The tanks also had problems of consistency, recorded failure of hydro-pneumatic suspension units and shearing of top rolls.
All Arjun’s problems except engine failure, were reported to have been resolved promptly. However, for engine failure, the Army field teams also have to bear some accountability as they are known to flog the vehicle at top speeds for long periods as the rides are smooth with superior hydro-pneumatic suspension compared to T-72s. This, in fact, prompted the suppliers Powerpack to install data loggers and automatic computer controls to prevent overheating.
This like the black box of an aircraft gave the complete log of the use of the vehicle but also regulated the speed on sensing overheating. It is learnt that results of close monitoring are being analysed and the engineers are confident that the problem can be fixed soon.
Continued lack Of Synergy
However, despite lofty exhortations from the Prime Minister downwards, what has been most difficult to achieve and standing in the way of making Arjun, a success is the lack of synergy between the user, on the one side, and the developer on the other.
Arjun is not treated with the same deference as other Russian tanks, either because there is reluctance to study and follow the manual of operations and maintenance provided by the producer or because they find it difficult to switch from the T-72 mode.
Although several recommendations of Dr Rama Rao Committee for revamping Defence Research and Development Organisation (DRDO) are under serious consideration for implementation, the immediate need in the case of Arjun is to thwart any misguided attempts by the Army to throw the baby with the bath water. The time, effort and money spent on development of indigenous fighting equipment, including Arjun, should not be squandered away in pursuit of pipe-dreams on technology or mindless fascination for foreign equipment.
