GlobalConflictहिंदी's video: Israel Russian Air Defence System Reputation

The S-400 Triumf, previously known as the S-300PMU-3, is an anti-aircraft system developed in the 1990s by Russia's Almaz Central Design Bureau as an upgrade of the S-300 family. It has been in service with the Russian Armed Forces since 2007. China was the first foreign buyer to make a government-to-government deal with Russia in 2014, while Saudi Arabia, Turkey, India and Belarus have all acquired, or expressed interest, in the system since. In 2017, the S-400 was described by The Economist as "one of the best air-defence systems currently made", and Siemon Wezeman of Stockholm International Peace Research Institute (SIPRI) said it "is among the most advanced air defense systems available." One system comprising up to eight divizion (battalions) can control up to 72 launchers, with a maximum of 384 missiles (including missiles with a range of less than 250 km. A gas system launches missiles from the launch tubes up to 30 metres (98 ft) into the air before rocket motor ignition. In April 2015, a successful test firing of the missile was conducted at an airborne target at a range of 400 km (250 mi); transporter erector launchers (TELs) carrying the long-range 40N6 may only be able to hold two missiles instead of the typical four due to their large size. Another test recorded a 9M96 missile using an active radar homing head that reached a height of 56 km. All the missiles are equipped with directed explosion, which increases the probability of complete destruction of targets. In 2016, Russian anti-aircraft missile troops received new guided missiles for S-300 and S-400 defense systems. The anti-aircraft missile system, designed to destroy aircraft, cruise, and ballistic missiles, can also be used against ground targets. The S-400 is able to intercept cruise missiles at a range of about 40 km due to their low-altitude flight paths. 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. The US$5.43 billion deal (₹40,000 crore) was formally signed on 5 October 2018, ignoring threat of US sanctions. The deliveries are expected to commence by the end of 2020 and brought into service in October 2020. The United States threatened India with sanctions over India's decision to buy the S-400 missile defense system from Russia because India chose S-400 over American origin Patriot PAC 3. In March 2021, U.S. Secretary of Defense Lloyd Austin discussed India's planned purchase of Russia's S-400 air missile system and threatened India with sanctions for buying S-400.
