India has sought time to "evaluate" Russia's offer of upgrading its Sukhoi-30 fleet to a near fifth-generation aircraft level, a top official of Russia\u2019s Rostec State Corporation has said. Victor Nikolayevich Kladov, the head of the Department of International Cooperation and Regional Policy, Rostec State Corporation, said it was upto India whether it wants to pick up the entire upgrade package or opt for selective modernisation. He said the pricing of the upgrade would also depend on that. Talking to a select group of reporters ahead of Russia's MAKS air show, he said India was evaluating the offer for the upgrade of Sukhoi Su-30MKI. "This question as far as I know was raised in St Petersburg between President (Vladimir) Putin and esteemed Prime Minister(Narendra) Modi (last month). The Indian Prime minister once again reiterated that the Indian side needs time to evaluate it\u2019s strategy of development and how to spend money," Kladov said. "The package is there. We are offering the package of modernising the Su-30 aircraft. It will obtain new capabilities, it will be very close to the fifth generation aircraft in capabilities. This is a deep modernisation everything should be changed engine, radar etc," he said. "Indian Air Force has to evaluate its strategy and then take a decision," Kladov said. The Su-30 fighter jets are developed by Russia's Sukhoi and built under licence by India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF).
