Background

Overview

The concept is central to India's strategic autonomy and national security, directly addressing the 'Aatmanirbhar Bharat' initiative in defence. It highlights the challenges and successes in developing complex indigenous technologies, impacting economic growth, job creation, and technological self-reliance, all critical themes for GS3.

India's pursuit of self-reliance in defence aims to reduce dependence on foreign imports and bolster strategic autonomy by fostering domestic design, development, and manufacturing capabilities for critical military hardware. This initiative is crucial for national security, economic growth, and technological advancement, particularly in complex sectors like aerospace engineering.
