S-400 air defence missile system Expansion Plan
Indian Air Force Plans Expansion of S-400 air defence missile system
S-400 air defence missile system procurement is set to expand as India plans to acquire five additional squadrons from Russia following its reported success during Operation Sindoor last year.
According to ANI, the Defence Ministry is expected to soon consider a proposal from the Indian Air Force to strengthen India air defence capabilities with the additional units. The systems are likely to be deployed along both the eastern and western fronts.
India had earlier signed a $5.5 billion defence deal with Russia in 2018 for five squadrons of the S-400 air defence missile system. Of these, three squadrons are already operational. The remaining two are scheduled for delivery in 2026 and 2027.
S-400 air defence missile system expansion after Operation Sindoor
The S-400 air defence missile system reportedly demonstrated operational effectiveness during Operation Sindoor. Following this, the Indian Air Force is assessing the requirement for additional long-range surface-to-air missile systems.

Sources indicated that discussions with the Russian side are ongoing. A fresh tender may be issued soon for the additional five squadrons. Meanwhile, the Air Force is also looking to procure missiles in significant numbers to ensure layered protection across strategic zones.
The S-400 air defence missile system, known in Indian service as “Sudarshan Chakra,” is among the most advanced platforms globally. It is designed to detect and neutralise multiple airborne threats, including stealth aircraft, cruise missiles, drones and tactical ballistic missiles.
Capabilities and Strategic Impact
The S-400 air defence missile system can track targets up to 600 km away and intercept them at distances of up to 400 km. Each squadron consists of two batteries. Every battery includes six launchers, advanced radar systems and a control centre.
A single battery can carry up to 128 missiles, enabling sustained operations in high-threat environments. The system’s phased array radar enhances detection accuracy and response time.
Defence analysts note that the additional procurement would significantly boost India air defence capabilities, especially along sensitive border areas. However, final approval will follow official review by the Defence Ministry.
Further details regarding timelines and contract structure are expected once formal discussions conclude.
