1. Drones in Modern Warfare: An Overview

1.1 How Drones Are Used in Warfare

Drones serve multiple roles:

• Intelligence, Surveillance, and Reconnaissance (ISR): Real-time battlefield monitoring (e.g., U.S. MQ-9 Reaper).
• Combat Strikes: Armed drones like Turkey’s Bayraktar TB2 and China’s Wing Loong II.
• Electronic Warfare (EW): Jamming enemy communications (e.g., Russian Orion EW drones).
• Logistics & Resupply: Small drones delivering supplies (e.g., U.S. Kargo UAV).

1.2 Key Statistics

• Global Military Drone Inventory (2024): ~30,000+ (Source: SIPRI Military Expenditure Database).
• Fixed-wing: ~60% (long-range, high payload – e.g., MQ-9 Reaper).
• Rotary-wing (VTOL): ~40% (short-range, urban ops – e.g., Iran’s Shahed-136).
• Payload Comparison:
• Fixed-wing: 500 kg – 2,000 kg (e.g., U.S. RQ-4 Global Hawk).
• Rotary-wing: 5 kg – 200 kg (e.g., Chinese CH-4).

 Annexure 1 : India’s Military Drone Program – Challenges & Prospects

1. Overview of India’s Drone Ecosystem

India’s drone program has evolved from import dependency to indigenous development, driven by the Make in India initiative and post-2020 military reforms. The Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL), and private firms (e.g., ideaForge, NewSpace Research) are key players.

Key Indigenous Military Drones

2. Challenges Facing India’s Drone Program

A. Technological Gaps

• Engine Dependency: Rustom-II uses Austrian Rotax engines (imported), limiting mass production.
• Sensor & AI Shortfalls: Heavy reliance on Israeli (Elbit) and French (Thales) EO/IR systems.
• Stealth & Swarm Tech: Ghatak UCAV lags behind Chinese GJ-11 and U.S. RQ-180 in low-observability.

B. Slow Indigenous Development

• Rustom-II Delays: 15+ years in development; still not fully operational.
• Private Sector Bottlenecks: Startups lack funding for high-endurance drones (e.g., NewSpace’s CATS Warrior delayed).

C. Import Dependency

• Critical Imports: 70% of military drones are foreign-made (Israel’s Heron TP, U.S. MQ-9B SeaGuardian).
• Vulnerability to Sanctions: Risk of supply chain disruption (e.g., U.S. CAATSA on Russian deals).

D. Regulatory & Budgetary Hurdles

• Fragmented Procurement: Army, Navy, and IAF pursue separate drone projects.
• Funding Shortfalls: Only **1.2BallocatedforUAVsin2024−25∗∗(vs.China’s1.2BallocatedforUAVsin2024−25∗∗(vs.China’s4.5B).

3. Future Prospects & Strategic Initiatives

A. Policy Reforms

• Drone Policy 2.0 (2024): Incentivizes private sector R&D with PLI schemes.
• Theatre Commands Integration: Centralized UAV ops under Maritime & Air Defence Commands.

B. Indigenous Projects

Program	Goal	Timeline
Ghatak UCAV	Autonomous stealth combat drone	2027-2030
TAPAS-BH	Naval surveillance & ASW drone	2025-2026
CATS Warrior	Air-launched drone swarm (with HAL)	2026-2028

C. International Collaborations

• U.S. (MQ-9B Deal): 31 SeaGuardians for $3B (pending approval).
• Israel (Technology Transfer): Joint production of Hermes 900 in India.

D. Export Potential

• Target Markets: Southeast Asia (Vietnam, Philippines), Africa (Nigeria).
• Competitive Edge: Lower-cost alternatives to Chinese Wing Loong.

5. Conclusion

India’s drone program is at a critical juncture:

• Challenges: Import reliance, slow R&D, and budget constraints.
• Opportunities: Private sector growth, U.S./Israel partnerships, and export potential.
• Strategic Imperative: Accelerate Ghatak UCAV and swarm tech to counter China’s drone dominance in the Indian Ocean.

Recommendations:

1. Increase R&D funding to $3B/year by 2030.
2. Fast-track engine indigenization (GTRE’s PTAE project).
3. Integrate drones with theatre commands for centralized ops.

Annexure 2 : China's Military Drone Program – Challenges, Prospects, and Strategic Leap

1. Overview of China’s Drone Ecosystem

China has rapidly emerged as a global leader in military drone technology, leveraging state-backed research, mass production, and aggressive exports. The People’s Liberation Army (PLA) and state-owned enterprises (e.g., AVIC, CASC, CETC) dominate development, while private firms (e.g., DJI, EHang) support dual-use innovations.

Key Indigenous Military Drones

Drone	Type	Status	Capabilities	Deployment
Wing Loong II	MALE UCAV	Mass-produced	1,500 km range, 6x air-to-ground missiles	PLA, export (20+ countries)

2. Challenges Facing China’s Drone Program

A. Export Restrictions & Geopolitical Pushback

• U.S. Sanctions: CAATSA penalties on buyers of Chinese drones (e.g., Turkey, UAE).
• Western Mistrust: Bans on DJI drones in NATO countries over data security concerns.

B. Technological Dependencies

• Engine Limitations: Reliance on Ukrainian AI-222 engines for early Wing Loong models (now indigenized).
• Sensor Gaps: Inferior EO/IR systems compared to U.S./Israeli equivalents (e.g., Raytheon’s MS-177).

C. Operational Shortfalls

• Combat Inexperience: Limited real-world testing outside proxy conflicts (e.g., Yemen, Libya).
• Electronic Warfare (EW) Vulnerability: Weak counter-drone defenses exposed in Ukraine.

D. Overcapacity & Market Saturation

• Price Wars: Chinese firms undercut rivals (Wing Loong II sold for 2M∗∗vs.MQ−9’s∗∗2M∗∗vs.MQ−9’s∗∗30M), risking profit margins.

5. Conclusion: China’s Path to Dominance

China is poised to leapfrog the U.S. in drone warfare by:

1. Scaling Swarm Tech: GJ-11 and FH-97A will outnumber adversaries.
2. Monopolizing Export Markets: Price dominance in Global South.
3. Carrier & Hypersonic Integration: Projecting power beyond the "First Island Chain."

Critical Vulnerability: Overreliance on exports for R&D funding—if sanctions tighten, progress could stall.

2. Challenges Facing the U.S. Drone Program

A. High Costs & Slow Production

• **MQ-9 Reaper costs ~30Mperunit∗∗(vs.China’sWingLoongIIat 30Mperunit∗∗(vs.China’sWingLoongIIat 2M).
• Bureaucratic procurement delays (e.g., MQ-9B SeaGuardian for India stuck in approval since 2020).

B. Vulnerability to Electronic Warfare (EW)

• Jamming & Spoofing: Russian EW in Ukraine disrupted U.S.-supplied drones.
• Counter-Drone Gaps: Lack of scalable anti-swarm defenses.

C. Export Restrictions & China’s Market Dominance

• ITAR Regulations limit sales to allies (e.g., UAE forced to buy Chinese CH-4 after MQ-9 restrictions).
• China controls ~40% of global drone exports (vs. U.S. at ~30%).

D. Lagging in Drone Swarms

• China’s GJ-11 swarms are operational, while U.S. Gremlins program remains experimental.

5. Conclusion: Can the U.S. Maintain Its Lead?

The U.S. still leads in high-end drones (stealth, carrier ops, AI), but China is closing the gap with:
✔ Mass production & cost advantage
✔ Faster swarm deployment
✔ No export restrictions

U.S. Must:

1. Accelerate NGAD & attritable drones to offset China’s numbers.
2. Relax ITAR rules to compete in Global South markets.
3. Invest in counter-swarm EW (e.g., lasers, microwave weapons).

China’s Leap Potential: If it masters hypersonic drones (2026+), it could surpass U.S. airpower by 2030.
