“As for the supply of S-400, everything is going according to plan, the Indian colleague did not ask here to speed things up,” Putin said.

He emphasized that "everything is going fine."

In September, Russian Deputy Prime Minister Yuri Borisov said that India’s S-400 air defense systems will be delivered within 18-19 months.

In October 2018, during negotiations between Russian President Vladimir Putin and Indian Prime Minister Narendra Modi, the parties signed a contract for the supply of S-400 in the amount of more than $ 5 billion.
