In a landmark move to boost self-reliance in defence capabilities, the Ministry of Defence has identified an Indian firm to establish a maintenance, repair, and overhaul (MRO) facility for the S-400 air defence system, officially named ‘Sudarshan Chakra’. The facility will be set up in collaboration with Russia’s Almaz-Antey, the original manufacturer of the system.
The decision comes in the wake of the system’s crucial performance during Operation Sindoor, India’s military retaliation in May following the April 22 terror attack on tourists in Pahalgam. During Pakistan’s attempted drone and missile strike on over 15 Indian cities on the night of May 7-8, the S-400 system played a decisive role in intercepting and neutralizing incoming threats, safeguarding military installations across the northern and western sectors.
A senior Defence Ministry official confirmed that the MRO facility plan had been under consideration for some time, but the events of Operation Sindoor accelerated the process. The selection of the Indian firm followed rigorous phases of security clearance and capability testing. Rules of engagement (RoE) for the facility have also been drafted, and a formal announcement is expected shortly.
“This is a huge step forward for our armed forces. The S-400’s effectiveness in Operation Sindoor was widely acknowledged, and having a domestic maintenance facility will ensure constant operational readiness while reducing dependence on foreign support,” the official said.
Another official familiar with the matter called it a “landmark achievement” in India-Russia military technical cooperation. He said the decision aligns with the government’s ‘Make in India’ initiative and would help mitigate challenges posed by international sanctions and global supply chain disruptions.
India had signed a deal with Russia to procure five S-400 systems. Three have already been delivered. During the Shanghai Cooperation Organisation (SCO) Defence Ministers’ meeting in China on June 26, Russian Defence Minister Andrey Belousov confirmed that the remaining two will be delivered in 2026 and 2027, respectively.
Named after the divine weapon of Lord Vishnu, the S-400 ‘Sudarshan Chakra’ is capable of engaging aerial targets up to a range of 400 km. Its integration into India’s defence infrastructure marks a significant leap in securing the nation’s skies against modern threats.
