The Indian Ministry of Defense said it expects delivery schedule for the last two S-400 batteries to be slightly shorter, at least for the S-400’s 4th Squadron. According to New Delhi, the fourth S-400 battery could arrive by the end of the year, with the last batch coming in early 2026.
In 2018, India signed a major $5.43 billion contract with Russia to acquire five units of the Triumf air defense system on the S-400. The agreement is potentially under the US to counter the US enemy through the Sanctions Act (CAATSA), which aims to punish the country for engaging in important defence transactions with Russia, Iran or North Korea. This was confirmed amid concerns about sanctions.
Despite the looming threat of sanctions, India has driven its purchases driven by strategic defence needs, particularly in light of tensions with neighbouring countries like China and Pakistan. The S-400 is renowned for its ability to engage multiple targets in a range of up to 400 km, making it a key asset for India’s long-range air defense strategy.
India’s escape from CAATSA sanctions can be attributed to several factors. First, the US has navigated a delicate balance in relations with India, recognizing New Delhi as an important partner in countering China’s influence in the Indo-Pacific region. This strategic alliance unwillingly leads to impose sanctions from the United States, and could hinder the growth of military and economic cooperation between the two countries.
Secondly, there was a considerable amount of diplomatic manipulation. India has spoken with the US and claimed that it was signed before the contract with Russia came into effect, suggesting that retroactively imposing sanctions is unfair. Furthermore, long-standing military relations between India and Russia provided historical context that the US had to consider.
In 2022, the US House of Representatives passed a legislative amendment that effectively waived CAATSA sanctions against India for the purchase of the S-400, indicating a political recognition of India’s strategic importance. This decision was seen as a recognition of the complexities of international diplomacy, where strategic interests often overwhelm legislative obligations.
The US approach to CAATSA was selective and had different outcomes in different countries. For example, Turkey faced sanctions on the purchase of the S-400, highlighting the case-by-case nature of US foreign policy decisions. Therefore, India’s non-authorization reflects both geopolitical calculations and the subtle application of US law, aiming to not alienate important alliances in strategically important regions.
The good news for India regarding the lack of CAATSA sanctions is hidden by a critical set-off from Russia, namely the delay in the provision of the S-400 Triumf air defense system, especially the last two squadrons.
Initially, Russia had promised to complete delivery of all five squadrons by the end of 2024. However, the ongoing conflict in Ukraine, which expanded Russia’s military resources and manufacturing capabilities, has pushed back delivery schedules significantly.
Reports show that the last two squadrons of the S-400, which were expected to strengthen India’s air defense against potential threats from Pakistan and China, will now only be delivered by August 2026. , which predicted that these advanced systems would be operational much faster to strengthen the country’s strategic position along its unstable borders.
The reason behind this delay is multifaceted, with the main cause being Moscow’s needs prioritizing domestic military requirements, particularly in light of the Ukrainian conflict. Furthermore, logistics challenges, including supply chain disruption and the complexities of international sanctions affecting Russia’s defense exports, exacerbated this issue.
This development forces India to reevaluate its defence strategy, perhaps to accelerate domestic initiatives to develop indigenous air defense systems, or to fill the gaps left by delayed Russian delivery. We are looking for alternative suppliers. This situation highlights the broader implications of global conflicts over international defense contracts and shows how geopolitical tensions directly affect national security programs.
India is strategically planning for Pakistan to deploy its S-400 victory air defense system, west and China to the north, along the most sensitive and unstable borders. The rationale behind this development is clear. It is to protect airspace from the potential air threats posed by these neighboring countries.
The system is particularly important along the line of Actual Control (LAC) with China, where tensions have been growing since the 2020 Galwan Valley collision.
The S-400’s advanced radar capabilities allow India to monitor and engage air threats at distances of up to 400 km, greatly enhancing its defensive attitude. The first three squadrons have already been deployed in areas like Punjab, near Pakistan, and Punjab, facing northeastern China.
This deployment strategy not only strengthens India’s air defense, but also serves as a deterrent against potential aggression, introducing India’s military power and preparation.
The S-400 Triumf, known by the NATO reporting name as the SA-21 Growler, represents a major leap in air defense technology from Russia’s Almaz-Antey Corporation. This mobile surface-to-surface missile system is designed to tackle a wide range of aviation threats, including aircraft, unmanned aerial vehicles, ballistic and cruise missiles.
The backbone of the S-400 system is a variety of sophisticated vehicles and equipment, each playing a distinct role in ensuring the effectiveness of the system. The S-400 battery is a 55K6E command and control system, usually mounted on a URAL-532301 mobile command post vehicle. The command center is equipped with an LCD console that manages data from a variety of radars, coordinates with other defense systems, prioritizes threats, and controls missile launches.
The radar system is the center of the detection function of the S-400. Known by NATO as “gravestones,” the 92N6E is a fire control and target tracking radar mounted on an MZKT-7930 8×8 vehicle. This radar not only tracks, but also attracts targets. Complementing this is a 96L6 cheese board, 3D surveillance and tracking radar, which can be carried in the same vehicle for automatic deployment.
For wider surveillance, the S-400 integrates the 91N6E Big Bird. This is a radar system that enhances the battery’s ability to detect and manage airborne threats over vast distances. This radar can also be deployed on an 8×8 trailer, providing positioning flexibility.
The missile components of the S-400 battery vary, and four types of missiles are used to cover different ranges and altitudes. The 40N6 missile boasts a 400-kilometer range and employs active radar homing to employ targets at distances.
The 48N6DM (or 48N6E3) extends its reach to about 250 km, an upgrade from the previous S-300 missile with a more powerful propulsion system. The 9M96E2 offers a medium range solution with a reach of 120 km, but the system also retains compatibility with the S-300PMU missiles, increasing flexibility.
The launch vehicle, or Tel (transporter erector launcher), is important for deploying these missiles. 5P85TE2 Automatic Promotion Launcher or 5P85SE2 Trailer Launcher is often used in conjunction with the BAZ-64022 or MAZ-543M tractor trailer for mobility. Each of these vehicles can carry up to four missiles, and when deployed in numbers can provide a significant punch.
For operational efficiency, the S-400 battery includes a vehicle for reloading missiles, allowing the system to maintain high speeds without having to return to the base for resupply. These logistical components are less attractive than missile launchers and radars, but are essential for sustained combat operations.
Integration with other systems is another facet in the S-400’s design. It can communicate and coordinate with various Russian defense systems, such as the S-300PMU2, S-300PMU1, TOR-M1, PANTSIR-S1, and more, creating layered defense networks that are difficult to penetrate. This feature is enhanced by radars such as Protivnik-Ge and Gamma-DE, which enhances the system’s ability to communicate with command posts and other radar systems for comprehensive air defense coverage.
The S-400 deployment strategy involves careful placement of radars to maximize its effectiveness, especially in challenging terrain where incoming threat radar cross sections can be operated for the benefit of the system. It is often the case.
From a practical application perspective, the S-400 has been deployed in various Russian regions, including Moscow, Kaliningrad and the Eastern Military District, demonstrating its strategic importance. Internationally, countries such as China, India, and Turkey either acquire or acquire these systems, despite the potential political consequences of US sanctions. , showing their global appeal.
Therefore, the S-400 Triumf is not just a missile system, but a complex and integrated air defense solution that combines advanced technology and strategic deployment to provide one of the world’s most frightening defenses against air invasions.
