Overview
- The Russian response to India’s tender was submitted in late August and is now being processed by the Defence Ministry as a project estimated at more than ₹50,000 crore.
- If contracted, the purchase would add five S-400 squadrons to the five India already ordered in 2018, with the existing fifth squadron due for delivery by November 2026.
- Officials expect deliveries from any new agreement to begin roughly three years after signing, and the proposal reportedly offers joint production of two units in India and Russian-supplied remainder plus MRO support.
- India is separately buying more than 280 interceptor missiles to replenish S-400 stocks after Operation Sindoor, where the system’s long-range performance increased political support for further buys.
- The proposal arrives alongside wider Russian offers, including the S-500 and Su-57, forcing New Delhi to weigh urgent capability needs against sustainment burdens and its push for indigenous projects such as Project Kusha and the AMCA.
