Modern defence equipment relies heavily on AESA radars, electronic warfare systems, encrypted communication networks, Battlefield Management Systems (BMS), satellite communication, and cyber defence technologies. These systems facilitate network-centric warfare, allowing seamless coordination among the Army, Navy, and Air Force.

Advanced electronics and secure communication technologies are therefore essential elements of Science and technology in defence, particularly for developing sophisticated and interconnected defence platforms.

Space and Advanced Manufacturing Technologies

Space technology plays a crucial role in defence through military satellites, NAVIC navigation, satellite communication, and intelligence gathering. At the same time, advanced manufacturing techniques such as 3D Printing (Additive Manufacturing), advanced composite materials, nanotechnology, and indigenous semiconductor-based electronics have reduced production time, improved equipment quality, and enhanced self-reliance in defence manufacturing.

These technologies strengthen Defence technology and Atmanirbhar Bharat by enabling domestic development of critical technologies and supporting a more capable India defence manufacturing ecosystem.

3. Government Initiatives and Current Status

• Atmanirbhar Bharat in Defence: The Government has prioritised indigenous design, development, and manufacturing to reduce import dependence. In FY 2024–25, India’s defence production reached a record ₹1.54 lakh crore, reflecting the growing strength of the domestic defence industry. This progress demonstrates the increasing importance of Defence technology and Atmanirbhar Bharat in strengthening India’s strategic autonomy.
