Flaws in T 90 Main Battle Tanks troubles Indian Army

Chandigarh: Inducted to serve as India's main battle tank just over three years ago, the Army's fleet of Russian-built T-90s have run into serious trouble.
The problems include critical flaws in its fire control system, availability of ammunition and, what military officers said, was avoidable overuse during training exercises, rendering many tanks in need of overhaul.
According to Jane�s Defence Weekly, the tank�s continuing technical flaws are "adversely impinging on the Indian Army�s operational preparedness."
Confirming the Jane�s report, senior Army officers told this newspaper that the French Catherine thermal imaging (TI) camera, which gives the T-90�s Belarussian (Peling IG-46) night sight its 3 km range and higher accuracy, is not "adequately tropicalised" and hence prone to malfunctioning in the extreme heat of the Rajasthan desert region, where temperatures inside the MBT routinely average between 55�C and 60�C.
During repeated manoeuvres in the Thar Desert, where the T-90s will ultimately be deployed in the event of an outbreak in hostilities, prolonged use under high temperatures had already "knocked out" between 80 and 90 of the Catherine TI cameras, rendering the FCS "unserviceable." The officers said that repeated efforts to correct the problem had been without success.
The TI cameras are the crucial "eyes" of the tank�s systems. At Rs 2 crores each, the Catherine TI system comprises almost one-sixth of each T-90�s total cost of Rs 11.75 crores.
One of the options currently being explored to rectify the FCS is to locally develop an airconditioning plant for the TI camera. For this, a former director-general of mechanised forces is understood to have already held discussions with some French manufacturers, including Thales (which makes the Catherine TI cameras). However, neither this nor the local vendors called in by the DRDO have had any success in this matter.
The Army, incidentally, does not have a D-G for its mechanised forces after Lt. Gen. G.D. Singh became deputy chief of staff at Army Headquarters recently. Under the circumstances, it could take any new D-G who is appointed quite a while before he can adequately address the T-90�s problems, possibly further delaying the MBT�s operational preparedness.
The problem of successfully integrating the Catherine TI camera with the Belarussian IG-46 sight is also believed to have considerably delayed the licensed production of T-90s at the Heavy Vehicles Factory (HVF) at Avadi. Sources said the indigenous T-90 production, as part of the transfer of technology agreement signed with Russia, which was scheduled to begin in 2006, has been deferred after problems were encountered in fitting out the FCS in assembled tanks. Of the total of 310 T-90 tanks, 124 were bought fully formed and kits were imported for the remaining 186 to be assembled at Avadi. The first locally-assembled T-90s rolled out of the HVF in January 2004, but these too have run into problems with the FCS.
According to the transfer of technology agreement, the T-90�s IG-46 sights were to be made at the Opto Electrics Factory at Dehra Dun, the gun at the Ordnance Factory Board facility at Rishikesh and its 1,000-horsepower engine by Bharat Earth Movers Ltd. All the three projects stand deferred, official sources said.
The T-90s are also facing a host of other problems, including a nearly exhausted inventory of ammunition. The tank�s 125 mm smooth-bore gun is electronically configured to fire imported Russian AMK-338 and AMK-339 shells, the supply of which has run out after innumerable exercises.
Surprisingly, the T-90�s gun has not been configured to fire the Indian-made AMK-340 shells. These shells have turned out rather dubious in quality, with over 150,000 rounds having to be destroyed, leading to the loss of over Rs 700 crores. Some AMK-340 shells have even burst inside the tanks, killing crew members, in at least one instance at Babina. Armoured Corps officers said many tank crews, who feared the shells would explode inside the barrel, had refused to use the faulty ammunition, and when forced to do so went to elaborate lengths, enabling them to fire from outside the tank.
According to the Armoured Corps officers, the ordnance factory board had triple-packed the 125 mm AMK-340 shells with propellant, but without adequate packing in between the layers to prevent leakage at high temperatures in which they are stored, often under the open sun. This had led not only to a near-complete freeze on regular firings but also "severely dented" the confidence of tank crews, sources said.
The Secunderabad-based Bharat Dynamics Ltd (BDL), which was scheduled to start production of 9M119 Refleks missiles for the T-90 early this year, has also fallen badly behind schedule amid failed trials. BDL is believed to have sought technical assistance from the Russians in building the Refleks (Nato designation: AT-11 Sniper) missile.
It was the T-90�s missile-firing capability that had initially clinched the Army�s decision in its favour way back in 2001. But with BDL unable to supply the missiles and the endless problems with the fire control system, many officers are of the view that the tank appears little better than the already proven T-72, also currently in service with the Indian Army.
