## India’s S-400 Air Defence System: Powering National Security in 2025

India’s S-400 air defence system has become the backbone of the nation’s aerial shield, especially amid rising regional tensions. In May 2025, the S-400 played a decisive role in thwarting a major drone and missile attack from Pakistan, showcasing its advanced capabilities and strategic importance.

## What Is the S-400 Air Defence System?

The S-400 Triumf, developed by Russia, is one of the world’s most advanced long-range surface-to-air missile systems. It can detect, track, and destroy a wide range of aerial threats—including aircraft, drones, cruise missiles, and even ballistic missiles—at distances up to 400 km and altitudes up to 30 km. Each S-400 unit can track up to 300 targets simultaneously and engage up to 36 of them at once.

## Latest Operational Success: May 2025

According to [India Today](https://www.indiatoday.in/india/story/indian-air-force-sudarshan-chakra-s-400-air-defence-missile-systems-foil-pakistan-drone-attacks-targets-neutralised-2721562-2025-05-08), on the night of May 7-8, 2025, Pakistan launched a coordinated attack using drones and missiles targeting multiple Indian military bases across northern and western India. The Indian Air Force’s S-400 systems, dubbed “Sudarshan Chakra,” intercepted and neutralized these threats, protecting key cities like Srinagar, Jammu, Amritsar, Ludhiana, and Bhuj. In a swift response, India also targeted and destroyed a Pakistani air defence system in Lahore.

## Deployment Status and Future Deliveries

India signed a $5.4 billion deal with Russia in 2018 for five S-400 squadrons. As of May 2025, four squadrons have been deployed, covering strategic regions including Jammu & Kashmir, Punjab, Rajasthan, and Gujarat. The final squadron is expected to be delivered by 2026.

## Why Is the S-400 Important for India?

With growing threats from both Pakistan and China, the S-400 provides India with a technological edge, acting as a deterrent against enemy airstrikes and missile attacks. Its rapid response and high interception rate make it a critical asset for India’s national security.
