India knows it is a far too big a weapons market for the US to dare antagonize. In any case Russia, not the US, is India's traditional arms supplier
India will press ahead with the procurement of five regiments of Russian-made S-400 Triumf advanced Air Defense Systems (NATO reporting name: SA-21 Growler) intended for service in the Indian military notwithstanding U.S. sanctions, Indian Defense Minister Nirmala Sitharaman said at a recent press conference.
Speaking to the press on June 5, the defense minister emphasized the close defense ties between India and Russia. “In all our engagements with the U.S., we have clearly explained how India's and Russia’s defense cooperation has been going on for a long time and that it is a time-tested relationship,” Sitharaman said. “We have mentioned that CAATSA cannot impact the India-Russia defense cooperation.”
The United States passed the Countering America’s Adversaries Through Sanctions Act (CAATSA) against Russia in August 2017 for reportedly influencing and manipulating the 2016 presidential election process. Core provisions of the CAATSA, including sanctions on Russian business entities and senior Russian political and business figures, came into effect in January 2018.
The Indian defense minister is expected to raise the issue of sanctions under CAATSA, which could kick in on any Indo-Russian defense procurement deal above $15 million, at the upcoming 2+2 talks between the Indian and U.S. defense and foreign ministers scheduled for this month in Washington DC.
India and Russia reportedly concluded price negotiations last month. The signing of the final contract is purportedly expected during a summit meeting between Indian Prime Minister Narendra Modi and Russian President Vladimir Putin scheduled for October 2018. New Delhi and Moscow concluded an inter-governmental agreement for the purchase of the S-400s already in 2016 (See: “India and Russia Ink S-400 Missile Air Defense System Deal”).
The total contract value is estimated at around $5.5 billion for five regiments. “The standard S-400 battery consists of four transporter erector launchers (TELs), four launch tubes per TEL, in addition to target acquisition and engagement (fire control) radar systems and a command post. (With an additional fire control radar system, a battery can consist of up to 12 TELs.),” I explained elsewhere. “Two batteries make up an S-400 battalion (also known as an S-400 division), whereas an S-400 regiment consists of two battalions.”
Neither Indian nor Russian officials have so far publicly commented on what type of surface-to-air missiles will be delivered to the Indian military under the deal.
