Small Parts, Big Impact – Role of Critical Ancillary Components in India’s Drone Manufacturing

Introduction: Rising Demand and Expanding Drone Adoption

India’s drone industry is at an inflection point. From defence and agriculture to infrastructure monitoring and logistics, unmanned aerial systems are being deployed across sectors at an unprecedented rate. The market is projected to expand from USD 654 million in 2024 to USD 1.43 billion by 2029, representing a compound annual growth rate (CAGR) of 17 %.

Further, India’s drone manufacturing potential could reach USD 23 billion by 2030, a figure that underscores both domestic expansion and export promise. This surge in demand is creating a ripple effect across the entire value chain, especially for ancillary suppliers, the manufacturers of precision components, materials and subsystems that determine whether a drone meets its design and performance expectations.

A robust ancillary base is essential. As drones become smaller and more sophisticated, the reliability of every part from sensors to housings will define India’s competitiveness in global markets.

Drone Manufacturing and the Role of Ancillaries A Launchpad for MSMEs

In modern defence and aerospace systems, even the smallest component can decide mission success. The quality of original equipment manufacturers (OEMs) and their drone systems depends on the precision of ancillary parts such as connectors, sensors, housings, fasteners and structural sub-elements. Eg-a misaligned connector can trigger a critical system failure mid-flight. Polymer housings with inadequate vibration resistance can impair avionics. Composite wings with minute deviations in tolerance can affect aerodynamics and stability. These are the foundation of airworthiness and reliability.

Drone manufacturing operates through tiered supply chain primes, subsystems, components and sub-components, and ancillaries form its crucial lower tier. For MSMEs and startups, this tier presents an accessible opportunity: lower capital investment, faster innovation cycles and meaningful participation in the national manufacturing agenda.

Today, India’s defence sector counts over 350 manufacturers working with more than 10,000 MSMEs in integrated supply chains. Reforms such as PLI schemes and liberalised procurement norms are helping smaller firms enter the ecosystem with better visibility and opportunity. As drones proliferate across civil and defence applications, dependence on ancillary suppliers for precision, scalability and reliability will continue to grow.

Rising Demand and Strengthening Supply Chains, R&D, Innovation, and Scaling

The surge in domestic and international demand is prompting Indian manufacturers to expand capacity and localise production. Government’s ban on importing finished drones, while allowing import of certain components, has accelerated domestic assembly and encouraged new entrants into manufacturing.

States such as Tamil Nadu, Maharashtra and Uttar Pradesh are emerging as major drone and defence hubs, supported by Defence Industrial Corridors that promote supplier clustering and local partnerships.

Manufacturers are responding with strong R&D investments in advanced composites, lightweight polymers, additive manufacturing and miniaturised electronics. India’s defence output reached ₹1.27 lakh crore in FY 2023–24, with exports touching ₹21,083 crore. Drone-related funding alone hit ₹311 crore in Q1 FY 2025, highlighting investor confidence in the sector.

However, for this momentum to be sustainable, India must evolve beyond final assembly. Atmanirbhar Bharat demands a fully indigenous value chain from raw materials and tooling to testing, certification and advanced materials. While certain inputs like motors, sensors and composites remain import-dependent, the private sector’s 20.8 % contribution to defence production marks encouraging progress. Building a resilient domestic supply chain is vital to insulate India’s manufacturing ecosystem from global disruptions and export restrictions.

Challenges and How to Bridge the Gaps

Despite rapid progress, several gaps must be addressed for India to fully unlock its potential:

• Certification hurdles can be overcome through faster, simplified approval frameworks and government-backed testing support.
• Limited access to advanced materials and tooling can be resolved through shared infrastructure and R&D clusters.
• Capital and scaling constraints require targeted fiscal incentives and technology-upgradation schemes.
• Fragmentation and skill shortages can be mitigated via OEM–MSME partnerships and focused training initiatives.
• Import dependence can be reduced through incentives for localised component production and material innovation.
• Restricted market access for MSMEs can be improved through procurement preferences and stronger local-content mandates.

Each of these measures represents a crucial step in developing a competitive and self-reliant manufacturing ecosystem for drones and allied technologies.

Conclusion: A New Horizon for Defence Manufacturing and MSMEs

Ancillary suppliers are the backbone of India’s drone and defence manufacturing story. By ensuring precision, reliability and innovation at every tier, they enable OEMs to deliver systems that meet both domestic and international benchmarks.

With policy consistency, continued investment and collaborative R&D, India’s drone ecosystem can scale to global leadership while driving MSME participation and employment. As demand accelerates and supply chains deepen, India stands at the threshold of becoming a global hub for drone manufacturing and ancillary innovation, hence, fulfilling the broader vision of Atmanirbhar Bharat through every link in its supply chain.
