Russian Ambassador to India, Denis Alipov, has confirmed that discussions between India and Moscow are ongoing regarding the procurement of additional S-400 air defense systems. This announcement underscores the continued strengthening of the "Special and Privileged Strategic Partnership" between the two nations.

In an exclusive interview on Wednesday, May 28, 2025, Alipov highlighted the exemplary performance of the S-400 system, along with the jointly-manufactured BrahMos missiles. He cited reports from "Operation Sindoor," a recent military operation, as evidence of their effectiveness. "From what we know, India has clearly stated the goals and undertook actions after having identified the targets and the terrorists it promised to do. As far as we know, during the operation, the S-400 system was used and the BrahMos missiles were engaged. Judging by the reports available, the performance of these weapons was exemplary," Alipov told news agency.

India and Russia have a long-standing and comprehensive defense cooperation agreement, guided by the IRIGC-M&MTC mechanism, headed by the defense ministers of both countries. This partnership has evolved beyond a simple buyer-seller dynamic to encompass joint research and development, co-development, and joint production of military equipment. Key projects include the supply of the S-400 systems, licensed production of T-90 tanks and Su-30 MKI fighter jets, supply of MiG-29 combat aircraft and Kamov helicopters, the INS Vikramaditya aircraft carrier (formerly Admiral Gorshkov), production of Ak-203 assault rifles in India, and the BrahMos missile program.

Sources suggest that India's interest in procuring more S-400 systems is driven by strategic planning and the need for enhanced military preparedness. When asked about the potential for further acquisitions, Alipov stated, "Our discussion, on this particular topic, as on many others, is ongoing. It is a continuous one, but it would be incorrect for me and also premature to speak about the results of it at the moment."

The S-400 Triumf, known as the "Sudarshan Chakra" in Indian service, is a mobile, long-range surface-to-air missile (MLR SAM) system developed by Russia's Almaz Central Design Bureau. It is considered one of the most advanced air defense systems globally, capable of intercepting a wide range of aerial threats, including fighter jets, ballistic and cruise missiles, drones, and stealth aircraft. The system can be deployed rapidly, becoming operational within five minutes while on the move.

India had signed a USD 5.43 billion deal with Russia in 2018 for five S-400 air defense systems. The first system was deployed in Punjab in 2021 to address aerial threats from both Pakistan and China. The S-400's capabilities include tracking over 100 targets simultaneously and engaging up to 36 targets at once using various missiles with ranges up to 400 km.

The Indian Air Force (IAF) strategically positioned its S-400 squadrons in Punjab, Rajasthan, and Gujarat to cover key airbases and cities, supported by mobile counter-UAS units and kamikaze drones. The S-400’s five-minute setup time enables quick redeployment, enhancing India's air defense posture.

Despite previous delays, three of the five contracted S-400 squadrons have been delivered to India as of 2025, with the remaining two expected by 2026. In parallel with these acquisitions, India is also pursuing its indigenous long-range SAM system project, "Project Kusha," targeting initial deployment by 2028-2029. This system is expected to include missiles with ranges of 150, 250, and 350 km.

Alipov also expressed satisfaction with the 'Made in India' BrahMos missiles, a product of the joint collaboration with Russia. "We have a joint venture, designing and producing of these weapons. We are very satisfied with the results of this collaboration," he noted. This highlights the deepening defense cooperation between the two countries, extending beyond conventional buyer-seller relationships to encompass joint development and production ventures.
