India's ‘Sudarshan Chakra’ gets more powerful: Fourth S-400 squadron arrives from Russia

India has received its fourth S-400 air defence squadron from Russia, significantly bolstering its long-range aerial defence. This delivery, part of a larger 2018 deal, follows earlier squadrons and is set for rapid deployment. The system has proven effective, notably during Operation Sindoor, and is integrating into India's broader 'Sudarshan Chakra' air defence network alongside indigenous projects like Kusha.
