What Happened
- The Defence Research and Development Organisation (DRDO) has reaffirmed its focus on developing indigenous advanced materials — including composites, ceramics, smart alloys, and stealth materials — as part of India's strategic push to reduce dependence on defence imports
- DRDO's Defence Materials and Stores Research and Development Establishment (DMSRDE), based in Kanpur, is the nodal lab working on non-metallic materials, polymer matrix composites, ceramic matrix composites (CMCs), elastomers, and carbonaceous nanostructured materials for defence applications
- Composite materials are being developed for unmanned aerial vehicles (UAVs), personal and vehicle armour, next-generation combat airframes, and stealth platforms
- Thermal barrier coatings are being developed for jet engines and spacecraft reentry applications, reducing dependence on foreign suppliers for aerospace-grade materials
- DRDO has been transferring these technologies to domestic industry partners as part of the Atmanirbhar Bharat in defence initiative
- Joint research with institutions like IIT Delhi and companies such as CUMI is ongoing for ballistic ceramics used in bulletproof jackets and armoured vehicles

Atmanirbhar Bharat in Defence — Self-Reliance Initiative
Atmanirbhar Bharat (Self-Reliant India) in the defence sector refers to a comprehensive policy framework launched by the Government of India to reduce dependence on foreign arms and equipment by developing domestic design, development, and manufacturing capabilities.
- India was historically the world's largest defence importer, with approximately 65–70% of defence equipment sourced from abroad; this has now reversed to approximately 65% manufactured domestically
- A phased import embargo was introduced from 2020, identifying specific weapons systems, platforms, and components that cannot be imported after specified dates, forcing domestic sourcing
- India's defence production reached a record ₹1.54 lakh crore in FY 2024-25; the government targets ₹3 lakh crore in production and ₹50,000 crore in exports by 2029
- Defence exports reached ₹21,083 crore in FY 2023-24, up from under ₹2,000 crore in 2014-15
- The defence budget for 2025-26 stands at approximately ₹6.81 lakh crore, representing about 1.9% of GDP
Connection to this news: DRDO's materials research directly supports the import embargo: when India cannot import specific composite structures, ceramics, or stealth materials for new platforms, domestic alternatives must be ready. DRDO's role is to develop and transfer these technologies to industry before the embargo timelines, ensuring operational readiness is not compromised.
DRDO — Organisation and Mandate
The Defence Research and Development Organisation (DRDO) is the R&D wing of India's Ministry of Defence, tasked with designing and developing cutting-edge defence technologies, systems, and materials to equip India's armed forces.
- Founded in 1958; operates 50+ laboratories and establishments across India, covering missiles, aeronautics, naval systems, electronics, materials, and life sciences
- Key laboratories relevant to materials: DMSRDE (Kanpur) — composites and non-metallic materials; DMRL (Hyderabad) — Defence Metallurgical Research Laboratory for advanced alloys and metals
- DRDO follows a Technology Readiness Level (TRL) framework — technologies mature from basic research (TRL 1) to full operational capability (TRL 9), at which point they are transferred to industry
- Successful DRDO programmes include Agni/Prithvi missiles, Tejas light combat aircraft (composite airframe), Arjun Main Battle Tank, and AUV systems
- DRDO's budget is approximately ₹23,855 crore in 2025-26
Connection to this news: DRDO's focus on composites and ceramics addresses a critical vulnerability: advanced structural composites for fighter jets, drones, and armour are high-value dual-use materials that major exporting countries often restrict under export control regimes (e.g., ITAR in the US). Developing indigenous capability removes this strategic chokepoint.
Advanced Materials in Modern Defence — Composites, Ceramics, and Smart Alloys
Advanced materials science is increasingly at the core of military capability, determining the performance of platforms ranging from fighter jets to infantry armour systems.
- Composite materials (carbon fibre reinforced polymers, fibre-reinforced plastics) offer high strength-to-weight ratios, reducing aircraft weight by 20–30% compared to metals, enabling higher performance and fuel efficiency
- Ceramic matrix composites (CMCs) withstand extreme temperatures (above 1,200°C) and are used in jet engine hot sections, reducing thermal damage and enabling higher thrust-to-weight ratios
- Ballistic ceramics (boron carbide, silicon carbide, alumina) are used in personal body armour (PASGT, MICH helmets) and vehicle armour plates, providing superior protection at lower weight than steel
- Smart alloys (shape memory alloys like nitinol) are used in actuators, vibration dampening, and morphing structures in aerospace applications
- Stealth materials (radar-absorbent materials, RAM coatings) are critical for reducing the radar cross-section of aircraft and missiles, enabling stealth capability
Connection to this news: DRDO's stated goal of developing these specific categories of materials (composites, ceramics, smart alloys) maps directly to the capability gaps India faces when import restrictions are applied. Domesticating these materials enables the full indigenisation of platforms like the Advanced Medium Combat Aircraft (AMCA), naval vessels, and next-generation armoured vehicles.
