Russia has dispatched the fourth batch of the S-400 Triumf air defense system to India, expected to arrive by mid-May, according to a defense source cited by The Times of India. This shipment follows the May 7 anniversary of Operation Sindoor. The fifth batch is anticipated to reach India in November.
The S-400 system has demonstrated its capability in safeguarding India’s military and civilian assets against missile threats from Pakistan during conflicts in the past year. Pre-dispatch inspections by officials from the Indian Air Force (IAF) were completed by April 18, as reported by the Russian state-owned news agency TASS. The latest system is set to be deployed in Rajasthan to reinforce missile defense along the Pakistan border, while the fifth system will be stationed at the border with China.
The initial two batches of S-400 systems have been positioned along the border with Pakistan, while the third has been placed in India’s eastern sector. In 2018, India formalized an agreement to procure five S-400 squadrons for $5.43 billion, aimed at enhancing its missile defense capabilities. Following the effective utilization of these systems against Pakistan last year, India’s Defense Acquisition Council (DAC) approved the acquisition of an additional five S-400 systems on March 27, emphasizing the need to expand the country’s missile defense network.
Additionally, India plans to acquire 280 short- and long-range S-400 missiles to replenish stockpiles used during Operation Sindoor and to establish a reserve of long-range weaponry. It is estimated that India launched 11 long-range S-400 missiles against Pakistan, targeting fighter jets, early warning systems, and transport aircraft.
In response to evolving threats, India is in the process of developing a multi-layered integrated air and missile defense system called ‘Sudarshan Chakra,’ which incorporates the S-400 (long-range), Barak-8 (medium-range), and an indigenous Project Kusha (extended-range air defense system) to form a comprehensive security shield against various threats, including ballistic missiles, drones, and hypersonic weapons.
Furthermore, India is considering the procurement of Russian Pantsir-S1M short-range air defense systems to protect its S-400 Triumf batteries from smaller threats, such as drones.
