India’s Ministry of Defence has approved a Comprehensive Annual Maintenance Contract (CAMC) for the S-400 air defence systems, ensuring 90% operational availability. This strategic move enhances India’s air defence capabilities against threats from adversaries like China and Pakistan, particularly in sensitive areas like Ladakh. The contract includes maintenance, repairs, and training for Indian Air Force personnel, while promoting indigenous capabilities in line with the Aatmanirbhar Bharat initiative. Despite scrutiny over defence ties with Russia, this long-term framework ensures uninterrupted support and mitigates risks from Western sanctions, reinforcing India’s commitment to national security and operational readiness of advanced missile systems.
