In 2018, India inked a contract valued at almost $5.43 billion to buy five regiments of S-400 to augment its home air defences. In response to the need for strong defence, recently, India got the fourth S-400 system, which will strengthen the Indian Air Force&#8217;s capacity to detect and neutralise enemy aircraft, drones, ballistic and cruise missiles. The induction follows on the heels of growing security threats in the region and brings India&#8217;s military modernisation and preparedness efforts to the fore. While referring to the layered air-defence system, the official government statements have accentuated the need for it in order to maintain national security.<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Key Highlights of India Receives Fourth S-400 Air Defence System<\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">India has welcomed the Russian S-400 Triumf&#8217;s fourth regiment.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The S-400 system is reckoned one of the top combat systems of surface-to-air missile defence systems in the world.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">India signed the S-400 Deal in October 2018 with Russia.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The entire deal is estimated to be worth approximately $5.43 billion.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The Russian S-400 system is mainly operated in India by the Indian Air Force.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The system can be used for detecting and destroying aircraft, drones, cruise missiles and ballistic missiles.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The range of action for engagement of the target is 400km.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">S-400 is part of the integrated air defence system that will comprise an integral part of India&#8217;s air defence system, according to official PIB information.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Earlier versions of S-400 have already been deployed in dynamic areas of the country by India.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">This is expected to bolster the air defence in the western part, and the fourth regiment is anticipated to advance India&#8217;s defence capabilities in this regard.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">India is set to conduct the delivery of the fifth (and final) regiment of the S-400 missile system in the near future to the country.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The Defence Acquisition Council has also given its nod to the other proposals pertaining to procuring S-400 armament and enhancing the capabilities of the existing system.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400\">PYQs Related to Defence Systems and Missiles<\/span><\/h2>\n<table>\n<tbody>\n<tr>\n<td><b>Exam Name<\/b><\/td>\n<td><b>Year<\/b><\/td>\n<td><b>Question<\/b><\/td>\n<td><b>Options<\/b><\/td>\n<td><b>Answer<\/b><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400\">UPSC CDS<\/span><\/td>\n<td><span style=\"font-weight: 400\">2021<\/span><\/td>\n<td><span style=\"font-weight: 400\">India procured the S-400 missile defence system from which country?<\/span><\/td>\n<td><span style=\"font-weight: 400\">A.

The long-range aerial combat capability in India against modern ballistic missile attacks and foreign planes will receive a boost from the advanced system. The Government&#8217;s official release has pointed to the significance of an integrated air defence network to protect national interests and strategic assets. The development also brings to light India&#8217;s close defence ties with Russia. The acquisition of such systems, such as the S-400, plays a crucial role in ensuring the security of the Indian subcontinent and military deterrence as India reinforces the modernisation of its armed forces.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Russian-made S-400 &#8216;Triumf&#8217; is one of the world&#8217;s most advanced long-range air defence missile systems that has been developed.
