India has received its fourth squadron of the Russian S-400 "Sudarshan" air-defence system [1].
This delivery marks a significant expansion of India's long-range air-defence capabilities. By integrating these advanced systems, the Indian Ministry of Defence aims to secure its airspace against a wider array of aerial threats and enhance its strategic deterrence.
The arrival of the fourth squadron [1] is part of a broader procurement strategy known as Project Kusha. This acquisition is governed by a contract signed in 2018, which is valued at $5.4 billion [2]. The agreement specifies the purchase of five S-400 squadrons in total [3].
Russia continues to deliver these systems to Indian territory to fulfill the existing agreement. The S-400 is designed to track and engage aircraft, drones, and ballistic missiles at long ranges, a capability that allows India to monitor a larger perimeter of its borders.
Government officials said the final delivery will conclude shortly. The fifth and final squadron is expected to arrive by the end of 2026 [4].
Once the full complement of five squadrons is operational, the Indian military will possess one of the most dense long-range surface-to-air missile networks in the region. This buildup reflects India's ongoing effort to modernize its military hardware while maintaining a strategic partnership with Russia despite shifting global geopolitical pressures.

The completion of the S-400 delivery schedule signifies India's commitment to a multi-layered air defence architecture. By securing these Russian assets, India reduces its reliance on any single supplier while establishing a formidable defensive shield that complicates the operational planning of regional adversaries.
