Mains-ready Analytical Notes
Major Debates/Discussions:
The debate around delegating lethal decision-making to machines. Concerns about accountability, human control, and potential for escalation. India's stance is often cautious, emphasizing human oversight.
Rapid development and deployment of AI-enabled systems and hypersonic missiles by major powers could lead to destabilization, new arms races, and lowered thresholds for conflict.
How emerging conventional technologies (e.g., highly precise long-range missiles, AI-driven C2, cyber attacks on nuclear C3I) impact the efficacy and stability of nuclear deterrence doctrines like MAD or minimum deterrence.
Technologies like AI, cloud computing, big data, and biotechnologies have dual-use applications, blurring lines between civilian and military R&D, leading to complex ethical and security implications.
The increasing reliance on networked systems for command, control, communications, computers, intelligence, surveillance, and reconnaissance makes them high-value targets for cyberattacks and electronic warfare, demanding robust security measures.
Historical/Long-term Trends, Continuity & Changes:
- Increasing Lethality & Range: Continuous trend of weapons becoming more powerful and having longer reach.
- Precision vs. Mass: Shift from massed armies/indiscriminate fire to highly precise, targeted strikes.
- Speed of Warfare: From days/weeks to real-time, instantaneous engagement possibilities.
- Blurred Lines: Between conventional and unconventional, war and peace (hybrid warfare), state and non-state actors.
- Human Element: Debate over the decreasing human element in warfare with increasing autonomy.
Contemporary Relevance/Significance/Impact:
- National Security: Maintaining technological edge is paramount for India's defense against traditional and asymmetric threats.
- Defense Modernization: India's push for indigenous defence production (Atmanirbhar Bharat) is driven by these evolving warfare concepts.
- Resource Allocation: Defence budgeting needs to prioritize investments in critical emerging technologies.
- Impact on Society: Cyber warfare's impact on civilian infrastructure, psychological operations.
- India's Strategic Autonomy: Developing indigenous capabilities in critical strategic technologies is key.
