India today announced that it will buy the S-400 Triumf air defence systems from Russia, worth over USD 5 billion (over Rs 33,000 crore).
The deal was announced following talks held between Prime Minister Narendra Modi and Russian President Vladimir Putin on the sidelines of the BRICS Summit being held here.
The two sides also decided to collaborate in making four state of art frigates besides setting up a joint production facility for making Kamov helicopters.
The development comes as Russia hopes to stave off tough competition from the Americans and the Europeans to continue being India's foremost defence supplier.
The most strategically important decision is the Inter Governmental Agreement for the purchase of S-400 'Triumf' long-range air defence missile system which has the capability to destroy incoming hostile aircraft, missiles and even drones at ranges of up to 400 km.
India and Russia have been in talks for over a year for the purchase of at least five systems of S-400 that will be a game changer in the region.
It is capable of firing three types of missiles, creating a layered defence, and simultaneously engaging 36 targets. If India signs the deal, it would be the second customer of the prized missile system after China which had struck a USD 3 billion (around Rs 20,000 crore) contract last year.
Another important deal is for four Admiral Grigorovich-class (Project 11356) guided-missile stealth frigates.
Under this deal, two vessels will come from Russian and while the other two will be built in India with Russian collaboration.
No decision has been made on the selection of the Indian shipyard.
This is in furtherance to the six Talwar-class frigates that Russia built for the Indian Navy between 2003 and 2013.
The complex agreement for production of 200 Kamov 226T helicopters domestically under a nearly USD 1 billion (around Rs 67,000 crore) deal to replace the country's aging Cheetah and Chetak choppers is yet another important defence deal between the countries.
