Fourth Squadron of Sudarshan Air Defense System Arrives from Russia

NEW DELHI, June 3: In a significant boost to India’s long-range air defense network, the fourth squadron of the S-400 Triumf, known in Indian service as the Sudarshan air defense system, has arrived from Russia.

According to the defense sources, the advanced air defense system reached India by sea a few days ago and is expected to be deployed in an operational sector shortly.

The latest delivery marks the arrival of the fourth of the five S-400 squadrons contracted by India under a 2018 deal with Russia. Three S-400 squadrons are already operational with the Indian armed forces and have been deployed in strategically important sectors.

India had signed the agreement for the procurement of five S-400 air defense squadrons in 2018. While the first three units were delivered and inducted over the past few years, the delivery schedule for the remaining two squadrons was affected by disruptions caused by the ongoing Russia-Ukraine War.

The fifth squadron of the S-400 air defense mission system is expected to reach India in the next few months. The Defense Acquisition Council (DAC) has already cleared the acquisition of five more squadrons of the S-400s.

India is also working on an indigenous programme, codenamed Project Kusha, to develop its own air defense systems capable of shooting down enemy drones at similar ranges as the Russian system.

The S-400 air defense missile system has a maximum strike range of 400 km. The S-400 Triumf was used extensively by the Indian Air Force during the May 7–10 military conflict with Pakistan, underscoring its operational significance and played a huge role in thwarting the Pakistan Air Force’s capabilities during Operation Sindoor, where it secured the longest recorded surface-to-air kill by bringing down a high-value Pakistan Air Force surveillance aircraft flying at over 300 km.

The S-400 is regarded as Russia’s most advanced long-range surface-to-air missile defense system, capable of tracking and neutralizing multiple aerial threats simultaneously.
