The Sector at a Glance

Defence technology and indigenisation concern a nation's ability to design, develop, produce, sustain and upgrade the platforms, systems and components on which its armed forces depend. The sector covered under this tab extends across military aerospace and aviation, including combat and transport aircraft, helicopters, unmanned aerial systems, aero-engines and avionics; land systems such as armoured vehicles, artillery and small arms; naval platforms and weapons; missiles and munitions; radars, electronic warfare and communication systems; and the defence-industrial production base that manufactures them under the Make in India framework.

The scope of this tab is not limited to the final platform. It covers the full defence-industrial chain behind it: research and design, materials and special alloys, propulsion, electronics and software, sub-systems and components, testing and certification infrastructure, production and integration, and the long-tail of maintenance, repair, overhaul and spares support that keeps equipment operational across decades. It is this complete chain, and not the licensed assembly of imported kits alone, that determines whether Bharat owns its military capability or rents it.

Why This Sector Is Critical

Defence capability is the final guarantor of national sovereignty, and its credibility rests on availability in crisis. Equipment that depends upon imported engines, seekers, electronics, software source codes or spares carries an inbuilt vulnerability: in times of conflict, sanctions or diplomatic pressure, supply can be delayed, conditioned or denied, and the operational readiness of entire fleets can be held hostage to decisions taken elsewhere. Even where platforms are assembled domestically, the dependency often persists at the level of critical sub-systems and lifecycle support.

This is why the BAP-I mandate treats defence indigenisation as a resilience imperative rather than a procurement preference. The sector also has a strategic multiplier effect: aerospace and defence technologies in materials, propulsion, electronics and precision manufacturing spill over into civil aviation, space, energy and industry. If indigenous capability fails to mature, Bharat remains exposed to supplier leverage, bears high lifecycle costs, and risks fielding forces whose ability to fight a sustained conflict is determined by external supply chains.

The Bharat Context

Bharat has built a substantial defence-industrial base over several decades, anchored by DRDO laboratories, defence public sector undertakings such as Hindustan Aeronautics Limited and Bharat Electronics Limited, ordnance production entities, and shipyards. Indigenous programmes in combat aircraft, helicopters, missiles, radars and warships demonstrate genuine design capability, and private industry and MSMEs have entered the sector in growing numbers. Persistent gaps remain, however, in aero-engines, advanced materials, high-end electronics and semiconductors, sensors and seekers, and in the testing and certification infrastructure needed to qualify indigenous products quickly; and long development cycles continue to push users towards imports.

The policy environment has shifted decisively towards self-reliance. The Defence Acquisition Procedure 2020 prioritises indigenously designed, developed and manufactured equipment; positive indigenisation lists progressively restrict imports of identified items; the Innovations for Defence Excellence (iDEX) programme and the Technology Development Fund support start-ups and MSMEs; the Defence Industrial Corridors in Uttar Pradesh and Tamil Nadu aim to cluster production; and the SRIJAN portal opens import substitution opportunities to domestic suppliers. Aatmanirbhar Bharat and Make in India frame this effort nationally. What remains absent is an integrated research-to-resilience architecture that addresses the deep technology gaps, shortens the path from prototype to induction and builds sustainable lifecycle sovereignty; and this is the gap that BAP-I seeks to address through this tab.

Importance of the Sector

Economy

The defence-industrial base is a high-value, technology-intensive segment of the manufacturing economy. Indigenous production retains within Bharat the capital that would otherwise flow abroad for platforms, spares and lifecycle support, and builds supplier ecosystems in precision engineering, electronics, composites and software. Defence exports to friendly nations add a further economic and diplomatic dimension. The aerospace segment, in particular, links military demand with civil aviation maintenance and component manufacturing. It is argued that a sustained, predictable domestic order book is the single most important economic lever for converting defence spending into an industrial asset.

Employment

Defence and aerospace manufacturing employ some of the most highly skilled engineers and technicians in the economy: aeronautical, mechanical, electronic and software engineers, materials scientists, test pilots and flight test engineers, quality and certification specialists, and machinists, welders, assemblers and maintenance technicians. Supplier tiers extend this employment deep into MSME clusters and industrial corridors. The sector also absorbs veterans whose operational experience is valuable in testing, training and lifecycle support. The constraint lies in the pipeline of specialised talent and in retaining it against competing global demand.

Entrepreneurship

Recent reforms have opened defence to private enterprise in an unprecedented manner. Start-ups and MSMEs can contribute in drones and counter-drone systems, electronic sub-systems, simulation and training, artificial intelligence applications, advanced materials, precision components and maintenance services. Programmes such as iDEX and the Technology Development Fund, combined with indigenisation lists and procurement reforms, provide entry points. The persistent obstacles are long trial and qualification cycles, irregular orders and working capital pressure; provided that these are addressed, defence can become one of Bharat's most dynamic arenas of deep-tech entrepreneurship.

Partnership

Indigenous defence capability requires structured partnership between DRDO and industry as development and production partners, between defence public sector undertakings and private firms across supplier tiers, between armed forces and developers for early user involvement, between academia and defence laboratories for fundamental research, and between Bharat and trusted foreign partners for co-development and co-production with genuine technology transfer. Such partnerships must be structured so that design authority and intellectual property increasingly rest in Bharat. BAP-I positions itself as the convening platform where these stakeholders can engage on shared research questions.

Research Focus Possibilities

BAP-I invites original research articles, policy papers, technical reports, diagnostic assessments, case studies and white papers across the following indicative research streams. The list is open-ended; contributions that connect a new question to the resilience objective of this tab are equally welcome.

A. Capability Gaps and Supply Chain Sovereignty

  • Mapping critical import dependencies in aero-engines, seekers, sensors, electronics and special materials, with risk modelling for sanctions and conflict scenarios
  • Assessment of the gap between licensed production and genuine design authority across major platforms
  • Spares, lifecycle support and maintenance, repair and overhaul sovereignty for legacy and imported fleets

B. Aerospace, Aviation and Platform Technologies

  • Indigenisation pathways for military aero-engines, propulsion and associated materials
  • Unmanned aerial systems, counter-drone capability and the domestic component base they require
  • Avionics, mission computers and embedded software: security of source codes and indigenous development
  • Synergies between military aerospace and civil aviation manufacturing and maintenance

C. Policy, Procurement and Industrial Base

  • Effectiveness of positive indigenisation lists and DAP 2020 provisions in shifting procurement towards indigenous design
  • Performance of the Defence Industrial Corridors and lessons for cluster-based defence manufacturing
  • Testing, trials and certification infrastructure: bottlenecks and models for faster qualification of indigenous products

D. Innovation, Enterprise and Human Capital

  • Outcomes of iDEX and the Technology Development Fund in converting start-up innovation into inducted capability
  • MSME participation in defence supply chains: working capital, order predictability and quality certification
  • Workforce readiness in aeronautical engineering, flight testing and defence electronics, with curriculum gap analysis
  • Co-development and co-production models with trusted partners, and safeguards against technology denial

Who Can Participate

This tab invites participation from DRDO laboratories, defence public sector undertakings, shipyards and ordnance production entities, armed forces and veterans' expertise, IITs, IISc, NITs and aeronautical institutions, private defence and aerospace manufacturers, start-ups and MSMEs in defence supply chains, industry associations, testing and certification agencies, policy think tanks, international collaborators and individual researchers with domain expertise. Contributions from practitioners, policymakers and academics carry equal standing within the BAP-I research framework.

The Resilience Objective

Every contribution under this tab must serve one purpose: building a defence-industrial and aerospace base in which Bharat designs, produces and sustains its own military capability, so that its armed forces remain ready whatever the external supply environment. BAP-I treats indigenisation not as a slogan but as the measurable foundation of strategic autonomy.

From Challenge to Contract: iDEX, India's Deep-Tech Support Architecture in 2024, and How Start-ups Can Serve Critical Infrastructure Protection

Abstract Article

By 2024 India had assembled a recognisable architecture for supporting deep-technology start-ups. Its most mature defence component, Innovations for Defence Excellence (iDEX), launched in 2018, had moved from grants to procurement, and in March 2024 it was extended through the ADITI scheme, which offers larger grants for critical and strategic technologies. Around it stood the Startup India programme, the Fund of Funds for Startups, a draft national deep-tech start-up policy and, in 2025, a research, development and innovation fund of Rs 1 lakh crore. This retrospective paper reviews what the iDEX model achieved by 2024, the reforms that would strengthen it further, and what its design offers to a field it was not built for: the protection of civilian critical infrastructure. It argues that the decisive feature of iDEX is not the grant but the identified user with a problem statement and a route to purchase, and it proposes a comparable challenge-to-contract mechanism for power, telecommunications, water, transport and port operators under a national resilience mandate.
