Russia is set to complete the delivery of five S-400 Triumph air defense systems to India by 2026, as part of a USD 5.43 billion contract signed in 2018. Four systems have already been delivered, with the final unit expected next year, despite previous concerns over potential U.S. sanctions under the CAATSA legislation. India has effectively utilized the S-400 systems, notably during Operation Sindoor, which targeted terrorist infrastructure in Pakistan, underscoring the strategic importance of these defenses. Moreover, India is considering acquiring advanced S-500 systems, reflecting its commitment to bolster its air defense capabilities amidst regional security challenges. This procurement highlights India’s proactive stance in enhancing its defense readiness against evolving threats.
