India to Receive Remaining S-400 Units by 2026

KKN Gurugram Desk | In a strategic move reinforcing Indo-Russian defense ties, Russia has confirmed the timely delivery of the remaining units of the S-400 Triumf air defense system to India. Speaking to the media on Monday, Roman Babushkin, Deputy Chief of Mission at the Russian Embassy in India, confirmed that the final two squadrons of the missile system are on schedule for delivery by 2025–2026, as per the official contract timeline.

The announcement comes amid heightened regional tensions and follows the successful deployment of the S-400 system during ‘Operation Sindoor‘, India’s swift counter-response to the Pahalgam terrorist attack earlier this year.

 S-400 System’s Role in Operation Sindoor

During his briefing, Babushkin revealed that the S-400 system played a key operational role in India’s defense posture during the brief but intense cross-border escalation with Pakistan, triggered by the Pahalgam terrorist incident.

“We understand that the S-400 systems functioned with high precision and effectiveness during the recent India-Pakistan skirmish. This is a testament to the strength of our long-standing defense cooperation,” said Babushkin.

The Russian diplomat stressed that given current geopolitical realities, particularly the changing security landscape in Europe and Asia, air defense systems are among the most promising areas of future India–Russia cooperation.

 History of the S-400 Deal: A $5.43 Billion Strategic Partnership

India signed the S-400 Triumf acquisition deal with Russia in October 2018, during the annual bilateral summit in New Delhi. The contract, worth $5.43 billion, was one of the largest-ever arms deals between the two nations.

Deal Highlights:

• Total Units Ordered: 5 squadrons

• Current Status: 3 squadrons delivered

• Delivery Deadline: Remaining 2 by 2025–2026

• Capabilities:

  • Long-range interception (up to 400 km)

  • Multi-target tracking and neutralization

  • Counter-stealth, cruise missiles, UAVs, and aircraft

 Why the S-400 Is Crucial to India’s Defense Doctrine

The S-400 Triumf is widely considered one of the most advanced air defense systems in the world. Its integration into India’s defense grid has dramatically improved the country’s airspace protection capabilities, especially in border zones prone to frequent incursions.

Strategic Advantages:

• Multi-layered air defense from low to high altitude threats

• Rapid deployment along borders

• Effective in no-fly zones and protecting strategic installations

• Interoperability with other missile systems in India’s arsenal (Akash, Barak-8, etc.)

The deployment of the S-400 system is viewed as a force multiplier in India’s defense ecosystem, particularly in the western and northern sectors.

Drone Threats and Anti-UAV Capabilities: A New Front

In light of the growing threat from drones—highlighted during India-Pakistan skirmishes and attacks on forward bases—Babushkin emphasized the importance of developing counter-drone technologies.

“Russia has extensive experience dealing with drone threats and is continuously modernizing its systems. We believe it’s in the mutual interest of both countries to collaborate on this critical front,” he said.

India and Russia are already holding bilateral discussions on the integration of anti-drone systems into India’s current and future defense frameworks.

 India-Russia Defense Ties: Beyond the S-400

Babushkin stated that Russia is open to expanding its defense collaboration with India, especially in the area of air defense, cyber security, drone technology, and military modernization.

India and Russia already collaborate on:

• BrahMos Missile Joint Venture

• Sukhoi and MiG aircraft servicing and upgrades

• Submarine leasing and technical cooperation

• Ka-226T helicopter production (delayed but under discussion)

Russian Foreign Minister Lavrov Likely to Visit India Soon

Adding to the momentum in diplomatic engagements, Babushkin hinted at a possible visit by Russian Foreign Minister Sergey Lavrov to India later this month.

“The exact date is yet to be finalized, but we expect the visit to take place soon,” he said.

The visit is expected to focus on:

• Strategic defense ties

• Security cooperation in Eurasia

• Indo-Pacific and BRICS discussions

• Expanding bilateral trade and energy ties

 Geopolitical Implications and the China Factor

The delivery of advanced air defense systems like the S-400 to India carries significant strategic implications, especially considering India’s border challenges with both Pakistan and China.

Experts point out that the S-400 deployment in eastern Ladakh strengthens India’s air dominance and acts as a credible deterrent against any aerial aggression from the Chinese PLA Air Force.

Moreover, the purchase despite U.S. CAATSA sanctions pressure reflects India’s sovereign defense decision-making and commitment to strategic autonomy.

India’s Defense Modernization Push Continues

India has aggressively expanded its defense procurement and modernization efforts over the past few years, including:

• Rafale fighter jets from France

• MQ-9B Predator drones from the U.S.

• Indigenous development of LCA Tejas Mk2

• Upgrades to air defense, cyber warfare, and space-based surveillance

The S-400 is a pivotal part of this modernization and signifies India’s shift toward advanced multi-domain warfare readiness.

 What Lies Ahead?

Likely Developments by 2026:

• Full integration of all 5 S-400 squadrons

• Operational anti-drone systems co-developed with Russia

• Expansion of joint defense R&D projects

• Enhanced interoperability among Indian Army, Navy, and Air Force with Russian systems

India’s future defense deals may include next-gen fighter jets, hypersonic weapons, and AI-driven combat systems, many of which could see Russian collaboration.

Russia’s confirmation to supply the remaining S-400 units by 2026 reaffirms the strength of the India–Russia strategic partnership. At a time when drone warfare, cross-border threats, and geopolitical uncertainties are on the rise, the relevance of high-end air defense systems like the S-400 is more critical than ever.

As India continues to build a robust, tech-enabled, and layered air defense network, its collaboration with Russia remains central to achieving that objective. ‘Operation Sindoor’ not only demonstrated India’s retaliatory capabilities but also validated the operational success of the S-400, reinforcing confidence in the long-term viability of the defense alliance.
