S-400 missile defence systems
GS Paper - 3 (Defence Technology)
The US has made clear to India that it is "discouraging" it from proceeding with its acquisition of S-400 missile defence systems from Russia but Washington will have to weigh "important geostrategic considerations" while taking a decision on growing calls for a presidential CAATSA waiver to New Delhi.
- In October 2018, India signed a USD 5 billion deal with Russia to buy five units of the S-400 air defence missile systems, despite a warning from the then Trump administration that going ahead with the contract may invite US sanctions.
- The Biden administration has not yet clarified whether it will impose sanctions on India under the provisions of the Countering America's Adversaries Through Sanctions Act (CAATSA) for procuring the S-400 missile systems.
- CAATSA is a tough US law that was brought in 2017 and authorises the US administration to impose sanctions on countries that purchase major defence hardware from Russia.
- The US has already imposed sanctions on Turkey under the CAATSA for the purchase of a batch of S-400 missile defence systems from Russia.
- India pursues an independent foreign policy and its defence acquisitions are guided by its national security interests, the Ministry of External Affairs (MEA) said, amid apprehensions over the possibility of US sanctions on New Delhi over the procurement of S-400 missile systems from Russia.
- The S-400 is known as Russia's most advanced long-range surface-to-air missile defence system.
- Quad - comprising Japan, India, Australia and the United States - is a grouping of four countries.
- In November 2017, the four countries gave shape to the long-pending proposal of setting up the "Quad" to develop a new strategy to keep the critical sea routes in the Indo-Pacific free of any influence.
