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 55ºC and 60ºC.
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.
But the fact remains that Russian military has been consistently outclassed by its American counterparts. This is just another example.
The T-90S has the 1A4GT integrated fire control system (IFCS) which is automatic but with manual override for the commander. The IFCS contains the gunner's 1A43 day fire control system, gunner's TO1-KO1 thermal imaging sight which has a target identification range of 1.2km to 1.5km and commander's PNK-S sight.
The gunner's 1A43 day FCS comprises: 1G46 day sight/rangefinder with missile guidance channel, 2E42-4 armament stabilizer, 1V528 ballistic computer and DVE-BS wind gauge.
The commander's PNK-4S sight includes a TKN-4S (Agat-S) day/night sight which has identification ranges of 800m (day) and 700m (night). The driver is equipped with a TVN-5 infrared night viewer.
