India to Set Up Domestic MRO Facility for S-400 Air Defence System
Indian Firm Selected for MRO Operations
- The Ministry of Defence has identified an Indian firm to establish a Maintenance, Repair, and Overhaul (MRO) facility for the S-400 Triumf air defence system in India.
Strategic Importance of the MRO Facility
- This facility will enable India to be self-reliant in maintaining advanced air defence systems.
- It aligns with the โMake in Indiaโ and Atmanirbhar Bharat
- It helps India mitigate supply chain disruptions and bypass international sanctions that may affect the availability of spare parts and technical support from Russia.
Role of S-400 in Operation Sindoor
- India currently possesses three S-400 systems, officially named Sudarshan Chakra.
- During Pakistanโs retaliation for Indiaโs Operation Sindoor in May 2025, the S-400 played a crucial role in intercepting and destroying drones and missiles aimed at over 15 Indian cities.
India’s Procurement of S-400 Systems
- India had signed a deal with Russia in 2018 for five S-400 systems at an estimated cost of $5.43 billion (approx. โน40,000 crore).
- Three systems have been delivered, with the fourth and fifth expected in 2026 and 2027, respectively.
- The deal had faced pressure from the U.S. under CAATSA sanctions, but India has remained firm on the decision due to the system’s critical capabilities.
Additional Information: What is the S-400?
- The S-400 Triumf is one of the worldโs most advanced air defence systems, developed by Russiaโs Almaz-Antey.
- It can detect, track, and destroy aerial targets including:
- Aircraft
- Unmanned aerial vehicles (UAVs)
- Cruise missiles
- Ballistic missiles
- The system can engage targets at ranges up to 400 km and at altitudes up to 30 km.
- It uses multiple missile types with varying ranges and is known for its multi-layered defence capability.
- S-400 radar and missile guidance systems are highly sophisticated, providing a 360-degree shield.
Significance
- Establishing an indigenous MRO for the S-400 is a strategic and technological milestone for India.
- It reduces dependency on foreign assistance for routine and emergency servicing.
- Enhances the operational availability and combat readiness of India’s air defence capabilities.
