  • Drone swarms: Coordinated groups of multiple drones operating together

Background & Context

With increasing use of UAVs including weaponised drones, loitering munitions, and drone swarms in warfare, counter-drone capabilities have become critical for national defence. India’s indigenous Bhargavastra system aims to provide a hard-kill, multi-layered response capable of detecting, tracking, and neutralising hostile UAVs, enhancing battlefield dominance and troop protection. The system's integration of various sensor types and a dual-layer kill mechanism allows it to effectively counter different classes and sizes of UAVs. The Make-II category under the Defence Acquisition Procedure supports the development of such advanced prototypes funded by industry, promoting self-reliance in defence technology. This system is a strategic step forward in complementing future air defence architectures like Sudarshan Chakra, which plans a layered defence approach by 2030.

Why This Matters for Exams / Exam Relevance

Bhargavastra is a notable recent development (demonstrated July 2026) emphasizing India’s progress in indigenous defence technology and counter-UAV warfare. Exam aspirants should note the system's unique features, Make-II context, developer details, and future defence integration plans, all of which are relevant for current affairs, defence technology, and security-related questions in competitive exams. Understanding terminology such as 'hard-kill', 'drone swarms', 'loitering munitions', and 'Make-II' procurement enhances conceptual clarity for multiple-choice and descriptive questions.
