Rewriting the Future of Warfare: How India’s Defence Ecosystem Must Master Speed and Scale

The Chief of Defence Staff, General N.S. Raja Subramani, addressed the gathering at the defence conclave, arguing that the character and economics of warfare are changing faster than existing military, acquisition, and industrial systems can adapt. India therefore requires a defence ecosystem capable of rapid learning, technological integration, economical production, resilient sustainment, and large scale delivery. The CDS structured his entire argument around the acronym “BUILD”, which encompasses the Battlefield, Understanding, Integration, Learning, and Delivery at Scale.

Battlefield: Changing Nature of War

Regarding the first pillar, the Battlefield and the changing nature of war, the future battlefield is assessed as increasingly transparent, connected, simultaneous, and contested across multiple domains. India must be prepared for continental and maritime challenges as well as space, cyber, electronic, and information warfare, rather than preparing for conflicts in isolation. Persistent and inexpensive sensors are reducing concealment, the traditional distinction between front and rear areas is disappearing, and the time gap between detection and engagement is being compressed from hours down to minutes or seconds.

Understanding: Changing Economics of Warfare

Moving to the second pillar, Understanding and the changing economics of warfare, commercial technologies, inexpensive drones, autonomous systems, and software are transforming traditional cost relationships in combat. The speaker argued against meeting every threat solely with increasingly expensive weapon systems, calling instead for the most economical means of producing the required military effect. These demands layered capabilities combining expensive and affordable systems, electronic warfare, directed-energy systems, deception, and both kinetic and non-kinetic means. Consequently, the defence industry should be judged not only by its technological sophistication, but also by its ability to produce economically, modify rapidly, sustain, replenish, and repair systems during operations. These new economics are driven by three fundamental factors: compute, through affordable computing powering drones and autonomous sensors; compatibility, via open architectures and software increasing interoperability; and collaboration, as start-up's , universities, engineers, students, and technology companies become integral parts of the wider defence ecosystem.

Integration: Technology, Data, and Industry

On the third pillar, Integration of technology, data, and industry, future combat effectiveness will increasingly depend not only on major metallic platforms but on the networks, data, software, and algorithms connecting sensors, platforms, and decision makers. Multi domain operations require highly interoperable networks, seamless data exchange, and robust decision support across all services. Data is identified as a strategic national resource and the core foundation of military AI, prompting a call for common data standards, secure sharing mechanisms, and a federated architecture where data can remain distributed yet accessible to decision-makers through appropriate interfaces. India’s robust software and engineering capabilities, alongside its extensive experience in building massive digital ecosystems, are presented as vital advantages that must be harnessed for defence. Furthermore, artificial intelligence must progress from mere peacetime demonstrations to operational warfighting applications, prioritizing intelligence analysis, mission planning, logistics, maintenance, wargaming, training, and decision support, while functioning reliably under degraded communications and incomplete data at the tactical edge while retaining appropriate human authority.

Learning: Adaptation as a Combat Capability

The fourth pillar focuses on Learning and adaptation as a vital combat capability. Because adversaries, industry players, technology companies, and non-state actors are simultaneously learning from contemporary conflicts, strategic advantage will decisively belong to the side that learns and adapts the fastest. Innovation must therefore move away from lengthy linear processes and shift toward rapid, continuous cycles of requirements generation, prototyping, testing, iteration, deployment, and ongoing improvement.

Delivery at Scale

The final pillar addresses Delivery at Scale, noting that India's next major industrial challenge is not merely demonstrating the capability to develop complex weapons, but proving that they can be produced quickly, economically, and in vast numbers. Industry must establish robust production lines, tooling, supply chains, inventories, and surge capacities capable of expanding production sharply when strategic circumstances demand. To achieve this, the CDS identified critical priority capability areas requiring deep cooperation between the armed forces, industry, academia, and technology institutions, including long-range precision effects produced at substantially lower costs and greater scale, unmanned surface and underwater systems alongside conventional naval platforms, indigenous control of propulsion engines, sensors, data algorithms, and electronics, the ability to rapidly scale production of explosives and propellants during conflict, domestic manufacturing of infrared seekers, electro optical equipment, and synthetic aperture radar sensors to eliminate supply chain vulnerabilities, strong domestic maintenance, repair, and overhaul capacity to keep systems operational throughout prolonged conflicts across varied environments, faster testing, quality assurance, and certification against spurious components and backdoors, and indigenous development of critical components to mitigate the risk of external denial.

The principal requirements placed directly upon the defence industry are volume, cost, and speed. Systems must be interoperable, built on open standards, designed for upgradeability rather than rapid obsolescence, and backed by resilient supply chains. The desired model is an integrated national defence ecosystem where the armed forces articulate operational problems, industry helps solve them, and both learn continuously from frontline field experience.

Priority Capability Areas

The CDS identifies several areas requiring cooperation between the armed forces, industry, academia and technology institutions:

• Long-range precision effects produced at substantially lower cost and greater scale.
• Unmanned surface and underwater systems alongside conventional naval platforms.
• Indigenous control of propulsion, engines, sensors, data, algorithms and electronics.
• Ability to scale production of explosives and propellants rapidly during conflict.
• Indigenous manufacture of IR seekers, electro-optical equipment and SAR sensors to reduce supply chain vulnerability.
• Strong domestic maintenance, repair and replenishment capacity so weapon systems remain operational throughout prolonged conflict and varied environmental conditions.
• Faster testing, quality assurance and certification, including verification against spurious components and electronic backdoors.
• Indigenous development of critical components and subsystems to reduce the risk of external denial.

Self-Reliance and Global Partnerships

Addressing the interplay between self-reliance and global partnerships, the speech presented them as complementary rather than competing objectives. Domestic capabilities to manufacture, sustain, upgrade, and maintain defence systems provide the foundation for strategic confidence and credibility, allowing India to transition from being merely a massive defence market into a trusted manufacturing, technology, and security partner capable of ensuring reliable and assured supplies.

Conclusion

In conclusion, under the overarching framework of the Defence Forces Vision 2047, true transformation requires faster experimentation and acquisition by the armed forces, strong investment and scalable capacity from industry, and deeper participation by academia and technology institutions. Ideas acquire true military value only when they are successfully converted into operational capabilities and delivered at scale, ensuring that India's defence transformation focuses relentlessly on faster learning, deeper industrial capacity, resilient supply chains, technological sovereignty, and trusted global partnerships capable of keeping pace with the rapidly evolving character of modern warfare.
