Detailed Analysis by The Indian Standpoint; The Future of warfare in 2025
The modern warfare system is changed, now technology plays a critical role in deciding the fate of the battle. In recent times we all witness the situations in which countries do not send their skilled army professionals or troops to the land of their enemies but they use technologies to target them with accurate precision. Some recent cases included India’s operation sindoor, Russian Drone attacks in Ukraine, Ukraine drone attacks in Russia, Israel attack on Qatar etc. While nations prepare themselves to attack with modern technologies, now the need of modern technological defence systems are also playing a major role. In this article we are going to discuss the standpoint of various nations and Indian Standpoints in detail about major Air Defence Systems.
Introduction
Air defence systems are rapidly being modernised as a result of the evolving threats in the 21st-century. Sky space is more threatened than ever before, from unmanned aerial vehicles/ systems (UAVs), cruise missiles and hyper sonic weapons to ballistic projectiles and hyper sonic threats. This article shows how nations around the globe are adjusting, improving, and innovating in order to defend their airspace. This article will help you to understand which systems are currently in use and by which country, and what recent changes are doing to strategic balances.
1. Need of Modern Air Defence Modernisation: What Drives It?
Several pressures combine to drive today’s upgrades in air defence:
- Threats are diverse, including drones as well as low-radar cruise missiles with hyper sonic weapons, hovering munitions and drones.
- The global geopolitical instabilities of US Standpoint, Western and Eastern Europe, South Asia and the Middle East. These regions are prone to frequent aerial conflicts or proxy wars.
- The rapid advancement of technology in the fields of radar, AI, directed energy weapons, missile seekers and AI has allowed for much more accurate tracking, interception and targeting.
- Risks associated with the supply chain and a desire to achieve strategic autonomy pushes nations towards developing their own indigenous systems instead of relying upon foreign suppliers.
