In a written reply in Lok Sabha, he said, "The last contracted price for each Mirage-2000 aircraft in the year 2000 was Rs 133 crore. The contract for upgrade was signed in 2011 wherein the cost of upgrading one aircraft was Rs 167 crore."
Antony said, "Applying an escalation of 3.5 per cent per annum as per the Pricing Policy Review Committee, to the contacted cost of the year 2000, it works out to be Rs 195 crore at 2011 levels. Thus, the upgrade has been undertaken at 85 per cent of the escalated cost of the aircraft."
To a separate question on deployment of Airborne Warning and Control System (AWACS), he said these are force multipliers for specific area cover and not for surveillance of the entire air space.
"Three AWACS aircraft are presently operationalised in the IAF. AWACS are meant as force multipliers for specific area cover and not for surveillance of the entire space of our country," he said.
All three AWACS are part of Network Centric Operations and are able to provide adequate coverage of specified areas in such perations, Antony said.
