India and Russia close to five S-400 anti-aircraft systems deal

India is close to buying at least five S-400 anti-aircraft systems from Russia for $2.5bn  as part of a larger deal believed to be worth around $7bn, unnamed sources in Delhi  told Kommersant yesterday.  Officials from the two countries are due to meet later in the week where they are also expected to discuss  the purchase of two Varshavyanka-class diesel-electric submarines, 48 Mi-17V-5 military transport helicopters, 150 BMP-2/2K armoured  vehicles and three Project 11356 frigates. 
India is Russia’s biggest military hardware client  and spent $4.7bn last year – 28% of Russia’s total arms exports.
