Science, Technology and Emerging Dimensions of Defence
This domain looks at how technology changes military capability and how India tries to innovate, absorb and counter new systems. The exam tests definitions and the ability to see both promise and vulnerability.
Core areas
- C4ISR-command, control, communications, computers, intelligence, surveillance and reconnaissance-is the information backbone of modern operations.
- Unmanned systems and drones provide persistence and reduce risk, but depend on data links and are vulnerable to electronic warfare and jamming.
- Artificial intelligence supports analysis, targeting and autonomy, but raises questions of accountability, data quality and human control.
- Hypersonic weapons, stealth, directed-energy weapons and quantum technologies are emerging; each creates counter-measures and arms-control debate.
- Space and cyber are war-fighting domains as well as support domains. India's DRDO, iDEX and defence innovation ecosystem aim at indigenous design, while dual-use technologies blur civilian and military boundaries.
Worked example
A question describes a drone swarm attacking an airbase and asks for its main advantage and main vulnerability. Reasoning: the advantage is saturation and low cost per unit; the vulnerability is dependence on communication, navigation and EW-resistant software. A good answer balances offensive utility with counter-drone measures such as jamming, spoofing and layered air defence.
Traps that cost marks
Do not assume a new technology automatically wins a war. Do not confuse AI-enabled decision support with fully autonomous weapons. Do not ignore electronic warfare when discussing drones. Do not treat space or cyber as only civilian domains. Do not claim a capability without its logistics and training tail.
