India and Russia have signed a $5.4 Billion S-400 Triumf surface-to-air missile deal on Friday during an annual bilateral meet in New Delhi, according to the Economic Times.
The delivery of the five advanced S-400 Triumf squadrons will begin in October 2020.
The deal has been signed despite the looming threat of US financial sanctions.
In mid-July, Indian Defense Minister Nirmala Sitharaman said that Delhi and Moscow had reached the final stage in talks on the deliveries of S-400.
The United States has been trying to prevent other countries from buying S-400 from Russia, in particular by invoking its Countering America’s Adversaries Through Sanctions Act (CAATSA) which envisions punitive measures for any third party that carries out major transactions with the sanctioned Russian companies.
