All S-400 air defence missile systems will be delivered to India by 2025, according to the Russian Deputy Chief of Mission in India Roman Babushkin.
“The production of S-400 missiles to be delivered to India has started,” Babushkin said.
External Affairs Minister S Jaishankar will visit Russia on March 22 and March 23 to attend a meeting of the Russia-India-China trilateral.
The S-400, an upgraded version of the S-300, had previously only been available to the Russian defence forces.
It is manufactured by Almaz-Antey and has been in service in Russia since 2007.
The S-400 is known as Russia’s most advanced long-range surface-to-air missile defence system. China was the first foreign buyer to seal a government-to-government deal with Russia in 2014 to procure the lethal missile system.
India and Russia signed a $5 billion S-400 air defence system deal in October 2018.
