Air defense has always been a central aspect of warfare. In South Asia, the phenomenon carries immense significance due to compressed reaction times. In this context, one of the most-hyped systems is the Russian-made S-400, touted by New Delhi as a one-stop solution to counter aerial threats from both Pakistan and China.
The 2025 conflict between India and Pakistan marked an important chapter in testing the S-400 technology. The conflict began on May 7, when India attacked what it alleged were terrorist targets in both Pakistani-held Kashmir and Pakistan proper, using drone and missile strikes. The conflict lasted for four days, culminating in a U.S-facilitated ceasefire. However, the brief conflict debunked a lot of the myths regarding the S-400 technology.
First, India claimed that the mobile S-400 would be able to control Pakistan’s airspace. In contrast, Pakistani aircraft continued to operate freely, according to official briefings by the Pakistani military. Although the Pakistan Air Force (PAF) aircraft were in their own airspace, they were still within the air defense range.

The May 2025 India-Pakistan war played a pivotal role in eroding India’s long-standing notion of conventional superiority. Seven months ahead, the echoes of the conflict continue to shape military choices. The post-crisis environment shows predictable trends, marked by sabre-rattling via hawkish statements by the civil and military leadership, followed by military procurements. Most recently, India has signalled a mega aircraft deal, with the announcement of the induction of 114 Rafales.

In an era of novel threats, a layered defensive shield is once again at the centre of US strategy. The announcement of the Golden Dome by President Trump shortly after assuming office has given rise to new expectations, questions, and concerns regarding the project.
The capability is envisioned as a comprehensive missile shield for the continental United States (CONUS) against ballistic missiles, hypersonic vehicles, cruise missiles, and UAVs. Conceived as a multi-tiered system, it aims to integrate existing missile defences with new space-based platforms. The layered system, combining land, sea and space-based sensors
