S-400: Why India is buying more fighter-jet hunter ‘Sudarshan Chakra’ that gave Pakistani Air Force sleepless nights

India is set to significantly bolster its air defence network by purchasing approximately Rs 10,000 crore worth of missiles for its S-400 system from Russia. This move aims to enhance long-range strike and interception capabilities, following the system's reported success in downing Pakistani aircraft. Discussions are ongoing, with a Defence Acquisition Council meeting expected to consider the proposal.
