  • The Drone Revolution in Modern Warfare

    Why in the News?

    On March 29, 2026, reports highlighted the profound impact of Iran’s Shahed drones in the ongoing conflicts in West Asia. These “kamikaze” drones have challenged the supremacy of multi-million dollar air defense systems, signaling a paradigm shift where the economics of attrition are becoming as important as traditional firepower.

    What Makes Drone Warfare a “Game Changer”?

    The rise of Unmanned Aerial Vehicles (UAVs) like the Shahed-136 represents a shift toward Asymmetric Warfare.

    • Cost Imbalance: A Shahed drone costs between $20,000 and $50,000, while the missiles used to intercept them (like the Patriot) cost nearly $4 million each.
    • Swarm Tactics: Drones are often deployed in large numbers to overwhelm sophisticated radar and interceptor batteries.
      • Drone swarms are groups of autonomous drones that coordinate and operate together as a single intelligent system through communication networks, sensors, and AI algorithms.
    • Key Features
      • Autonomous Coordination
      • Each drone can: Share information with nearby drones
      • Adjust movement in real time
      • Collective Intelligence
      • Self-Healing Capability
      • If one drone fails, others reorganize automatically without collapsing the mission.
    • Sustainability: Maintaining an F-16 fighter jet costs roughly $25,000 per hour, nearly the total cost of the drone it is trying to shoot down.
    • Attrition: If a drone is lost, it is merely a financial loss; if a fighter jet is downed, the military loses a high-value asset and a highly trained pilot.

    How Does the Shahed-136 “Kamikaze” Drone Operate?

    The Shahed-136 (and its Russian variant, the Geran) is a “one-way” attack UAV with the following technical specifications:

    • Stealth: It flies at low altitudes (20–30 meters) to stay below traditional radar detection.
    • Navigation: Uses a push-propeller engine (noted for its “lawnmower” sound) and carries explosives in its nose.
    • Range: Capable of traveling up to 3,000 km.
    • Mechanism: It does not fire missiles; it is the missile, detonating upon impact with the target.

    What are the Modern Counter-Drone Solutions?

    To combat the high cost of traditional interceptors (Patriot, THAAD), militaries are moving toward Directed Energy Weapons (DEW) and low-cost interceptors:

    1. Laser Weapons: Systems like the HELIOS Laser (used by the US Navy) destroy targets using concentrated heat. They are extremely cost-effective per shot but can be hindered by bad weather (fog/rain).
    2. Acoustic Detection: Using technology to recognize the specific engine sounds of drones.
    3. Low-Cost Interceptors: * Sting: A $2,000–$4,000 interceptor drone used by Ukraine.
      • Merops: A specialized American anti-drone system being rapidly deployed to West Asia.
      • LUCAS: The US-made “Low-cost Uncrewed Combat Attack System” ($35,000).
    [2025] With reference to Unmanned Aerial Vehicles (UAVs), consider the following statements: 
    1 All types of UAVs can do vertical landing. 
    2 All types of UAVs can do automated hovering. 
    3 All types of UAVs can use battery only as a source of power supply. 
    Which of the statements given above are correct? 
    (a) Only one (b) Only two (c) All the three (d) None

  • [11th March 2026] The Hindu OpED: AI and the national security calculus

    PYQ Relevance[UPSC 2023] Introduce the concept of Artificial Intelligence (AI). How does AI help clinical diagnosis? Do you perceive any threat to privacy of the individual in the use of AI in healthcare?Linkage: The article discusses AI as a dual-use technology with security implications, highlighting concerns about surveillance, military integration, and governance of AI systems. The PYQ connects through debates on ethical risks, regulation, and societal impacts of AI deployment.

    Mentor’s Comment

    The rapid rise of Artificial Intelligence (AI) has pushed it from a commercial technology to a strategic national security asset. The debate intensified after American AI company Anthropic urged the U.S. government to classify Chinese AI labs like DeepSeek, Moonshot AI, and MiniMax as national security threats. The controversy reflects a deeper policy dilemma: Should AI be treated like nuclear technology requiring strict controls, or like a dual-use digital technology that thrives on open innovation? The issue has implications for military decision-making, global technological competition, and governance of autonomous systems.

    Is AI becoming a national security technology comparable to nuclear weapons?

    1. Dual-Use Technology: AI functions as a general-purpose technology used for civilian innovation and military operations. Unlike nuclear weapons, AI also drives sectors such as healthcare, finance, and digital governance.
    2. Military Integration: AI models assist in accelerating the military “kill chain”, supporting target identification, intelligence analysis, and operational decisions.
    3. Technological Diffusion: AI research occurs across universities, private firms, and open-source communities, enabling rapid global diffusion.
    4. Comparative Argument: Nuclear non-proliferation succeeds due to scarcity of fissile material, whereas AI relies on widely accessible resources like data and computing.

    What is AI model distillation and why is it controversial?

    1. Model Distillation: Distillation involves training smaller AI models using the outputs of larger frontier models to replicate capabilities at lower computational cost.
    2. Industrial-Scale Claims: Anthropic alleges 16 million interactions with its Claude model through around 24,000 accounts, suggesting systematic distillation efforts.
    3. Strategic Advantage: Distillation enables competitors to achieve frontier-level performance at a fraction of the cost of original research.
    4. Intellectual Property Issues: Companies argue distillation violates terms of service and proprietary model safeguards.

    Why are export controls and technological restrictions facing limitations?

    1. Circumvention of Restrictions: Export controls on advanced chips and inputs often face workarounds through alternative supply chains or domestic development.
    2. Human Capital Mobility: AI researchers frequently work across countries, making technological containment difficult.
    3. Diffusion of Knowledge: AI research spreads through academic publications, open-source models, and global conferences.
    4. Policy Ineffectiveness: Restrictions may fail to prevent competitors from achieving comparable performance, as illustrated by emerging Chinese AI models.

    Do corporate guardrails effectively regulate military uses of AI?

    1. Corporate Governance Limits: Private companies can modify or remove safeguards when responding to government contracts.
    2. Defense Integration: AI firms increasingly compete for military and national security contracts, accelerating integration into defence systems.
      1. Example: Some firms accept permissive contracts allowing military use of AI models, illustrating the competitive pressure in defence technology markets.
    3. Regulatory Gap: Corporate policies alone cannot substitute state-led governance frameworks for military AI use.

    Why does AI governance require international cooperation?

    1. Inevitable Military Adoption: Armed forces globally are integrating generative AI into surveillance, cyber warfare, and autonomous systems.
    2. Need for Global Norms: Effective regulation requires plurilateral commitments among states rather than unilateral corporate decisions.
    3. Human Control: Governance frameworks must ensure meaningful human oversight in lethal decision-making systems.
    4. Restrictions on Mass Surveillance: Global norms should prohibit large-scale civilian surveillance enabled by AI systems.

    Way Forward: Strengthening Global Governance of AI in National Security

    1. Multilateral AI Governance Framework: Establishes global rules for responsible AI deployment through platforms like the United Nations and the UNESCO which already adopted the Recommendation on the Ethics of Artificial Intelligence (2021) promoting transparency, accountability, and human rights protection.
    2. AI Safety and Risk Management Regimes: Strengthens international cooperation through initiatives like the Global Partnership on Artificial Intelligence (GPAI) and the OECD AI Principles, which promote responsible AI innovation, democratic values, and safeguards against misuse.
    3. Regulation of Military AI Systems: Develops binding norms on autonomous weapons through negotiations under the United Nations Convention on Certain Conventional Weapons (CCW), focusing on meaningful human control over lethal autonomous weapons systems (LAWS).
    4. Global Technology Export and Monitoring Mechanisms: Expands export-control regimes such as the Wassenaar Arrangement to include AI algorithms, advanced chips, and surveillance systems to prevent uncontrolled proliferation.
    5. Data Governance and Digital Rights Protection: Aligns AI regulation with frameworks such as the European Union AI Act, which classifies AI systems by risk level and restricts high-risk surveillance technologies.
    6. International Research Collaboration: Promotes open but secure collaboration among states, universities, and companies through forums like the G20 and World Economic Forum, ensuring innovation while maintaining safeguards.
    7. India’s Strategic Role: India can leverage platforms such as the BRICS, Quad, and G20 to push for ethical AI standards, responsible military use, and inclusive technological governance.

    Conclusion

    Artificial Intelligence is transforming the intersection of technology, geopolitics, and national security. Unlike nuclear technology, AI cannot be easily contained due to its open research ecosystem, global talent mobility, and digital diffusion. Effective governance therefore requires international norms, state-led oversight, and responsible corporate practices to balance innovation with security.
