Why Is Drone Warfare in the News?
A global obsession with drones has emerged in modern warfare. From Hezbollah’s fiber-optic-guided drones against Israel, Ukraine’s deep strikes into Russian hinterland under Operation Spider Web, to the May 2025 India-Pakistan four-day conflict where both sides used small UAVs at massive scale — drones have taken centre stage in modern military strategies. This is a direct UPSC GS Paper 3 (Defence, Internal Security, S&T) topic. The UPSC Mentorship Program at Riyasat IAS Mentorship covers such defence-tech developments with complete analytical depth.
Drone Warfare — Key Facts for UPSC Prelims
| Concept / Fact | Detail |
| Operation Spider Web | Ukraine’s drone-based strikes inside Russia using containers |
| Coordination Altitude | Restricted airspace between fighter jets and helicopters |
| India-Pakistan May 2025 | Four-day conflict — massive UAV deployment by both sides |
| Iron Dome (Israel) | Air defence missile — $40,000-$50,000 per missile |
| Iron Beam (Israel) | Directed Energy Weapon (DEW) — $2-$3.50 per shot |
| Drone Wall | European layered network of counter-drone systems |
| Golden Dome | US space-based counter-drone initiative |
| Sudarshan Chakra | India’s nationwide terrestrial + space-based C-UAS by 2035 |
| C-UAS | Counter-Unmanned Aircraft Systems |
5 Critical Facts — Drone Warfare UPSC 2026
1. Revolution or Evolution? The Doctrinal Debate
The invention of airspace itself was a revolution — it gave warfare a new 3D dimension. But drones are not a new dimension — they are a new “weapon system” developed within the existing airspace. Drones fly in the “Coordination Altitude” (between fighter jets and helicopters) — restricted airspace, not a new battlespace. The strategic implication: drones reshape ground warfare more than aerial warfare. Infantry and tanks must find new ways of hiding; manned aircraft (Su-30, Rafale) still maintain decisive air superiority. Secure Prelims Program 2026 covers such doctrinal concepts in MCQ-ready format.
2. Operation Spider Web and Intelligence Imperative
Under Operation Spider Web, Ukraine caused heavy damage to Russia’s strategic air fleet deep inside Russian territory using drones hidden in special containers. This established a new doctrine: real-time intelligence is now the top priority to detect and foil such far-reaching plans at early stages. Drones have extended the boundaries of kinetic warfare from border regions to hundreds of kilometres inside enemy interior — making 24×7 protection of critical assets (military bases, refineries, power grids) essential.
3. The Economics of Counter-Drone Warfare — Game-Changer
The cost asymmetry is the most decisive UPSC analytical angle:
- • Traditional air defence missiles like Iron Dome — $40,000 to $50,000 per missile
- • Cheap commercial drones — $500 to $5,000 each
- • Result: Using Iron Dome against drone swarms is economically unsustainable
- • Iron Beam (laser DEW) — $2 to $3.50 per shot — viable for drone swarm defence
This makes Directed Energy Weapons (DEWs) a structural game-changer for counter-drone warfare. UPSC Mains GS Paper 3 (S&T + Defence) expects this economic dimension in answers.
4. AI and Ethical Crisis — The Autonomous Weapon Question
The inclusion of Artificial Intelligence in drones makes fully autonomous operations possible — drones that select and engage targets without human intervention. This raises a foundational ethical question: “Should a machine be allowed to make life-and-death decisions?” A United Nations (UN) committee is currently investigating this. UPSC GS Paper 4 (Ethics) and Essay paper angles converge here — autonomous weapons + AI ethics + international humanitarian law.
5. India’s Sudarshan Chakra Plan — The Indigenous Counter
India plans to establish a nationwide terrestrial and space-based counter-drone system by 2035, named the “Sudarshan Chakra.” Three structural pillars:
- (1) Terrestrial component — radar networks + electromagnetic jammers + kinetic interceptors at critical installations
- (2) Space-based component — satellite surveillance for early drone detection
- (3) Layered defence — multi-tier system covering urban centres, military installations, energy infrastructure
This is India’s response to evolving drone threats. The Riyasat IAS Mentorship Program covers such indigenous defence initiatives with policy + strategic dimensions.

UPSC Relevance — Drone Warfare and Sudarshan Chakra
For Prelims:
- Operation Spider Web — Ukraine’s container-based deep strike doctrine
- Coordination Altitude — drone flight zone
- Iron Dome vs Iron Beam — cost economics of air defence
- DEW — Directed Energy Weapons
- Drone Wall (Europe) and Golden Dome (USA) — C-UAS initiatives
- Sudarshan Chakra — India’s 2035 C-UAS plan
Mains (GS Paper 3 — Defence, Internal Security, S&T):
- Drone warfare — evolution vs revolution debate
- Cost asymmetry of modern warfare — economic warfare angle
- Autonomous weapons + AI ethics — international humanitarian law
- Real-time intelligence imperative — deep strike defence
- India’s indigenous C-UAS capability — Sudarshan Chakra plan

Practice Question:
“Drones are not creating a new dimension of warfare — they are reshaping ground warfare while making strategic depth a relative concept.” In light of recent global conflicts and India’s Sudarshan Chakra plan, examine the doctrinal and strategic implications. (250 Words, 15 Marks)
Conclusion
Drones are reshaping the cost economics and strategic depth of warfare. India’s Sudarshan Chakra plan is a timely indigenous response — but its success depends on real-time intelligence, indigenous DEW development, and ethical AI frameworks.
