India Set to Receive Fourth S-400 System from Russia as Defence Capabilities Expand Post Operation Sindoor

The government led by Narendra Modi has already approved the acquisition of five additional S-400 systems. These advanced missile defence platforms are capable of neutralising aerial threats at distances of up to 400 kilometres, effectively covering targets deep inside Pakistan, particularly east of the Indus River.

According to official sources, Indian Air Force officials completed the pre-dispatch inspection of the incoming system by April 18. The anti-ballistic missile system was subsequently shipped from Russia last week. Upon arrival, the fourth system is expected to be deployed in the Rajasthan sector to reinforce India’s missile defence posture against Pakistan.

India has also decided to procure 280 short- and long-range S-400 missiles to replenish inventory used during Operation Sindoor and to build a reserve of stand-off weapons. It is estimated that 11 long-range S-400 missiles were launched during the operation, reportedly targeting and destroying enemy fighter aircraft, airborne early warning systems, and transport aircraft.

During the same operation, Pakistan allegedly attempted to strike two S-400 units deployed in Punjab and Gujarat. However, the effectiveness of the Russian-made system and its long-range radar reportedly forced Pakistan to reposition its operational aircraft to bases in Quetta and Peshawar, indicating the strategic impact of the system on regional air operations.

The fifth S-400 system is expected to be deployed along the middle sector bordering China, further strengthening India’s multi-front defence readiness. In parallel, India is exploring the establishment of a maintenance, repair, and overhaul facility for the S-400 system within the private sector, with the possibility of technology transfer also under consideration.

To enhance protection of these high-value assets and counter emerging threats such as drones and loitering munitions, India is planning to procure at least 12 Pantsir air defence systems from Russia through a government-to-government agreement. Additionally, around 40 more systems are expected to be manufactured domestically under the “Make in India” initiative.

The phased deployment of advanced air defence systems underscores India’s strategic focus on strengthening its aerial shield and deterrence capability across multiple theatres. With additional acquisitions and domestic production plans underway, the S-400 programme is emerging as a cornerstone of India’s evolving defence architecture.
