Russia and India are currently engaged in negotiations over the potential sale of additional S-400 surface-to-air missile systems, according to statements from Russian authorities in Moscow this week.
The Russian Federal Service for Military-Technical Cooperation confirmed that India has shown interest in acquiring more of the advanced systems. “Russia is ready for this. Negotiations are underway,” the service told Interfax on the sidelines of an International Security Forum that opened in the Russian capital on Tuesday.
Dmitry Shugaev, who heads the FSMTC, noted last week that the existing contract to supply India with S-400 units continues to move forward on schedule. He had previously indicated that Russia remains open to further deliveries beyond the original agreement signed in 2017.
The S-400 systems have already demonstrated their capabilities, the Russian service stated, citing their performance during the India-Pakistan military conflict in May of last year. Three of the five units from the 2017 deal have been delivered so far, with a fourth expected to arrive before the end of this month and the final one by the close of the year.
In March, India’s Defense Acquisition Council approved a broad package of defense purchases valued at $25 billion. This included proposals for five additional S-400 units along with new aircraft and artillery systems as part of an accelerated military modernization effort.
New Delhi proceeded with the original S-400 purchase despite significant pressure from the United States at the time. The move underscores India’s determination to strengthen its air defenses amid regional tensions.
India ranks as the world’s fifth-largest military spender and the second-largest arms importer after Ukraine, based on data from the Stockholm International Peace Research Institute. More than 60 percent of Indian weaponry originates from Soviet or Russian sources.
At the same time, New Delhi has been advancing its Make in India initiative to boost domestic defense manufacturing. Officials have not confirmed whether future S-400 acquisitions would involve local production elements.
Earlier reports had suggested India might also explore the more advanced S-500 systems, which are designed to engage targets in low-earth orbit. However, current discussions appear focused on additional S-400 units rather than the newer platform.
The procurement approvals from March also cover transport aircraft intended to replace aging Soviet-era An-32 and Il-76 planes, as well as various artillery systems. These steps reflect India’s ongoing efforts to update its military capabilities across multiple domains.
Russian officials have emphasized their readiness to meet Indian requirements while fulfilling existing commitments. The FSMTC statement highlighted that the S-400 has “proven itself” in recent regional conflicts, providing context for the renewed interest.
Both countries maintain longstanding defense ties, with Russia continuing to serve as a key supplier even as India diversifies its sources. The outcome of the current talks could shape the next phase of that relationship.
