Why did India buy Russia’s S-400 air defense system ?

The S-400 is the most advanced long-range air defense missile system that went into service in Russia in 2007. It is designed to destroy aircraft, cruise and ballistic missiles, including medium-range missiles, and can also be used against ground installations. The S-400 can engage targets at a distance of 400 km and at an altitude of up to 30 km.

Russia’s s-400 anti-aircraft missile is a land-based mobile medium- and the long-range anti-aircraft missile is the fourth generation of the surface-to-air missile system. It is a new version of the s-300, which can be used to counter dense multi-target airstrikes in ultra-low-altitude, short-range to long-range, ultra-long-range full-altitude airspace, and is specifically optimized for fifth-generation fighter jets and complex interference environments, with anti-tactical capabilities and medium-range ballistic missiles.

The S-400 has two world-first technologies, the longest interception distance and the lowest interception height. These two technologies are among the number one in the world, well ahead of the U.S. “Sad” system. In fact, to achieve strategic checks and balances with the United States, Russia originally planned to design far, medium and near three anti-missile systems. However, limited by the defence budget, it can only build a common anti-missile system, which is also considered a mistake in developing the S-400 feared by the U.S. military.

Its technical performance is the radar maximum detection distance of up to 6000 km, the missile flight speed is divided into three levels, long-range Mach 11.3, medium-range 5.9 Mach, short-range 3.3 or 2.6 Mach, can track 300 targets simultaneously, 72 targets can be guided to target, 36 can attack. The radar detection range of wind targets is 360×14 degrees and damage range is 2-400 km. The radar’s range of detection for ballistic targets is 60×75 degrees and the damage range is 7-60 km. The maximum height of the intercept target is 30,000 meters and the minimum height is 10 meters. Unfortunately, extra-atmosphere targets were not considered at the outset of the design and therefore the launch altitude was lower than the United States sea-based standard-3lla interceptor missile.

India announced its intention to acquire S-400 ‘Triumf’ surface-to-air missile systems in 2015. The contract worth USD 5.43 billion was signed during the visit of President Putin to India in 2018 year.

China purchased six battalions of S-400 anti-aircraft missile contracts at the end of November 2014. In 2017, media reports said Russia had delivered several regiments of S-400 anti-aircraft missile systems to China. However, when the Russian delegation came to China again in 18 years to promote the second batch of eight S-400 anti-aircraft missile systems, China rejected the sale. Because we what Chinese do, they will make an exact same copy of s-400 and put their name, .”Red Flag-19″ in China’s research and development has matured in copying other country stuff.

Interestingly, India has also signed an agreement with Russia to buy S-400 missiles. The result is that it will buy S-400 missile equipment for five camps for $6bn, more than double the price sold to China.
