The biggest and shocking news of this time is coming out from the Indian defense corridors and the platform of global diplomacy, which has made the heartbeats of defense experts and superpowers around the world faster. The centuries-long strategic and military partnership between India and Russia is once again on the verge of creating history. Quoting media reports and defense sources, it has been revealed that after the spectacular success of the world's most lethal weapon 'S-400' (S-400 Triumph) in the field of air defense system, India has now set its sights on Russia's even more sophisticated and accurate weapons. In the coming days, in the high-level bilateral talks to be held between the top leadership of India and Russia i.e. Prime Minister Narendra Modi and President Vladimir Putin, a historic grand deal can be sealed regarding the acquisition of the world's most modern air defense system 'S-500' (S-500 Prometheus) and the fifth generation radar-invisible fighter jet 'Sukhoi Su-57' (Su-57 Felon). If this mega defense deal is finalized, it will take the firepower of the Indian Air Force to such an invincible height that it will prove impossible for any enemy country to match. Let us understand in detail and in-depth every aspect related to this high-profile diplomatic and defense stir. After the historic success of S-400, why is India moving towards S-500 and Su-57? When India made a deal with Russia for S-400 air defense missile system, there was heavy diplomatic pressure from Western countries and America. Despite this, India completed this deal keeping its national security paramount and today the S-400 is protecting the country's borders by becoming the shield of the Indian Air Force. Its accurate firepower and the technology to vaporize enemy planes or missiles in the sky from hundreds of kilometers away proved that Russian defense technology has no match. Now that modern warfare strategies are changing rapidly and neighboring countries are continuously enhancing their air power, India is feeling the need for an even more advanced defense that can destroy hypersonic missiles and even air attacks from space. This is why India is now seriously considering the options of including Russia's latest and most secret project 'S-500' and fifth generation stealth fighter jet 'SU-57' in its army. What is the specialty of S-500 Prometheus and Su-57 fighter aircraft, which makes them the most dangerous in the world? The 'S-500 Prometheus' developed by Russia is currently considered to be the world's most advanced anti-ballistic and anti-aircraft missile defense system. This system can not only shoot down conventional fighter planes and cruise missiles, but it also has the amazing ability to target satellites and hypersonic weapons present in the lower part of space. Its radar range and tracking capability is many times more powerful than the S-400. On the other hand, 'Sukhoi Su-57' (Su-57) is Russia's fifth generation twin-engine stealth multi-role fighter jet. Due to its radar-invisible (Stealth) design, this aircraft is fully capable of attacking at depth without being detected by the enemy air defense system. If Su-57 is included in the Indian Air Force fleet, it will give India such a strategic edge in the air force field, which will completely turn the geopolitical balance of South Asia in favor of India. Prime Minister Modi and President Putin's summit and the new future of India-Russia defense relations Defense cooperation between India and Russia is not a relationship between a contractor and a buyer, but it is a decades-old unbreakable trust that has stood the test of every international crisis. Despite all the sanctions and pressure from Western countries, India has maintained its energy and defense trade with Russia and strengthened it from time to time. Due to the personal rapport and strong diplomatic relations between Prime Minister Narendra Modi and President Vladimir Putin, the implementation of major agreements between the two countries has accelerated. In the upcoming summit, there is also expected to be an important discussion on co-production of these weapons in India under the indigenous transfer of defense technology i.e. 'Make in India'. Instead of just buying ready-made weapons, India is now emphasizing on acquiring technology, so that the country can become completely self-reliant in the field of defense manufacturing. The growing concerns of global superpowers and the maturity of Indian defense diplomacy. The uneasiness can be clearly seen in America, European countries and western defense corridors due to the sound of this possible grand deal between Russia and India. Western countries are constantly trying to ensure that India reduces its dependence on Russia, but India has always kept 'Strategic Autonomy' paramount in its foreign policy. It is a clear policy of India that whatever weapons are best and useful for the national security and sovereignty of the country, they will be selected in the interest of the country. These ongoing discussions regarding S-500 and Su-57 have proved that India is no longer going to bow down to any external pressure for its defense needs. This move will not only put the Indian Armed Forces among the most powerful forces in the world, but is also the biggest testament to India's growing diplomatic strength and independent decision-making capabilities on the global stage.
