Russia has delivered the fourth unit of the S-400 air defense system, known as 'Sudarshan' in India. This unit is expected to be deployed along the western border near Pakistan to strengthen air defense. Under the 2018 agreement for five squadrons, India has now received four, with the final unit expected by the end of 2024. The S-400 system can track targets up to 600 km and engage threats like aircraft and missiles within a 400 km range using cold launch technology. https://argusnews.in/national/india-receives-fourth-s400-sudarshan-air-defence-system-russia #creator program
