New Delhi: In what could be a game-changing arms acquisition, India is planning to acquire the new-generation Russian S-400 Triumf air defence missile systems that can destroy incoming hostile aircraft, stealth fighters, missiles and drones at ranges of up to 400-km.

Indian media quoting defence sources say the defence acquisitions council (DAC), chaired by defence minister Manohar Parrikar, will "soon" take up the proposal moved by the IAF to purchase around a dozen S-400 long-range systems from Russia. "The project is at an initial stage at present.

But it will be a government-to-government contract when it is finalized, with the S-400 systems being inducted over several years," said a defence ministry source. The procurement proposal comes ahead of Parrikar's impending visit to Russia, which will be followed by the Modi-Putin summit in Moscow in December.

It also comes around a year after China sealed a $3 billion deal with Russia for acquisition of six S-400 batteries.
