Published byEdited byRitaban MisraRussia has submitted a detailed proposal to India’s Defence Ministry for the acquisition of five additional squadrons of the S-400 Triumf long-range air defence system for the Indian Air Force, with the proposed project estimated to cost more than 50,000 crore.
Defence sources said the Russian response to India’s tender has been received and is currently being processed.
The proposal comes months after the Defence Acquisition Council (DAC) cleared the procurement of five additional S-400 squadrons in March 2026.
The decision followed the system’s reported performance during Operation Sindoor in May 2025, when India used its air-defence network against Pakistani aerial threats.
The additional systems are expected to strengthen India’s layered air-defence capabilities on both its western and eastern fronts.
INDIA ALREADY HAS 4 OF 5 S-400 SQUADRONS
India had signed a $5.43-billion (Rs 51,838 crore) agreement with Russia in 2018 for five S-400 squadrons. Four of those systems have now been received, while the fifth and final squadron is expected to be delivered by November 2026, according to defence sources.
The first three squadrons have been deployed across key sectors, including areas along the western and northern borders. The S-400 is designed to detect and engage a range of aerial threats, including aircraft, drones and missiles, at different ranges and altitudes.
The proposed procurement would effectively double India's planned S-400 inventory to 10 squadrons if the new deal is concluded.
The system gained particular attention following Operation Sindoor.
Western Air Command chief Air Marshal Jeetendra Mishra recently said the S-400 achieved what was possibly the longest recorded surface-to-air missile kill, destroying a Pakistani surveillance aircraft at a range of 314 km.
He also credited the system with engaging several Pakistani fighter aircraft.
NEW DEAL MAY INCLUDE TECHNOLOGY TRANSFER
Deliveries under the proposed contract are expected to begin around three years after the agreement is signed. Discussions are also understood to include establishing a maintenance, repair and overhaul (MRO) facility in India.
The proposal reportedly involves greater domestic participation, including the possibility of joint production of two units in India by the private sector under a technology-transfer arrangement, while three squadrons would be acquired directly from Russia.
The additional S-400 systems are expected to operate alongside India's indigenous long-range air-defence programme, Project Kusha, as New Delhi seeks to build a more comprehensive multi-layered air-defence network.
India is also separately pursuing additional S-400 interceptor missiles to replenish stocks and strengthen its inventory following Operation Sindoor. Reports have put the planned missile procurement at more than 280 missiles.
With the Russian proposal now under examination, the next stage will involve evaluation and negotiations before a final contract can be concluded.
