  A deal to purchase S-400 systems by India was first reported in October 2015. On 15 October 2016, during the BRICS Summit, India and Russia signed an Inter-governmental Agreement (IGA) for the supply of five S-400 regiments to India. On 1 July 2018, the Defence Acquisition Council (DAC), chaired by the then Defence Minister Nirmala Sitharaman, cleared the procurement. The deliveries were expected to commence within 24 months after contract signing (October 2020) while they would complete all deliveries within 60 months (April 2023). On 26 September 2018, the Cabinet Committee on Security (CCS), headed by the Prime Minister Narendra Modi further cleared the acquisition. The US$5.43 billion deal (₹40,000 crore) was formally signed on 5 October 2018, ignoring the threat of US sanctions.
  
  In March 2021, U.S. Secretary of Defense Lloyd Austin discussed India's planned purchase of Russia's S-400 air missile system and warned that the purchase of S-400 could trigger CAATSA sanctions.
