India Strengthens Air Defence as Fourth S-400 System Dispatched from Russia Ahead of Operation Anniversary

According to reliable sources, officials of the Indian Air Force completed the pre-dispatch inspection of the fourth system on April 18. Following this clearance, the system was shipped from Russia to India last week. It is expected to be deployed in the Rajasthan sector to further strengthen the missile defence grid against Pakistan.

During Operation Sindoor, the Russian-origin S-400 system showcased its formidable strike capability. India reportedly launched 11 long-range S-400 missiles against Pakistan, successfully targeting and neutralising fighter aircraft, Airborne Early Warning and Control Systems, and transport aircraft with precision.

The system’s long-range radar and strike envelope created a significant deterrent effect. Pakistan reportedly assessed that no aerial platform east of the Indus River was safe from Indian missile coverage. As a result, it was compelled to relocate its active fighter aircraft and aerial platforms to airbases in Quetta and Peshawar to remain outside the engagement range.

In a retaliatory attempt, Pakistan tried to target two S-400 systems deployed in Punjab and Gujarat. However, these attempts were unsuccessful, reinforcing the system’s defensive robustness.

In a further push to enhance national air defence, the central government has approved the acquisition of five additional S-400 systems, each with a range of up to 400 kilometres. As Operation Sindoor remains ongoing, India has also decided to replenish its missile inventory and build a strong reserve of stand-off weapons. Plans are underway to procure 280 short- and long-range S-400 missiles for this purpose.

Strategic deployment plans indicate that while the fourth system will be positioned along the Pakistan border, the fifth system is expected to be deployed in the middle sector along the China border. Simultaneously, India is working towards establishing a domestic Maintenance, Repair, and Overhaul facility for the S-400 system with private sector participation. The possibility of technology transfer is also under consideration to achieve long-term self-reliance in this domain.

To safeguard high-value systems like the S-400 from drone and loitering munition threats, India is further reinforcing its defence shield. Under a government-to-government agreement with Russia, India plans to procure at least 12 Pantsir air defence systems. Additionally, 40 more such systems are proposed to be manufactured domestically under the Make in India initiative, providing a substantial boost to indigenous defence production.

This development underscores India’s strategic focus on strengthening multi-layered air defence capabilities while simultaneously advancing domestic defence manufacturing and technological autonomy in an increasingly complex security environment.
