NEW DELHI -- Indian Prime Minister Narendra Modi and Russian President Vladmir Putin are expected to sign a deal in New Delhi this week for Moscow to supply S-400 air defense missile systems at a cost of over $5 billion, despite the threat of U.S. sanctions.
The two countries have been negotiating the deal since 2015. The purchase of five S-400 Triumf missile systems and associated equipment is expected to boost India's defense capability along its borders with nuclear-armed Pakistan and China. The S-400 is Russia's most-advanced long-range surface-to-air missile system and is planned for induction in the Indian Air Force by 2022.
