The TDF Scheme, or Technology Development Fund, is a flagship programme of the Ministry of Defence, executed by DRDO under the 'Make in India' initiative . Launched to promote self-reliance in defence technology, this grant-in-aid scheme specifically targets Indian MSMEs and startups, providing them with financial backing to design and develop cutting-edge defence and dual-use technologies that are currently not available with the Indian defence industry . If you are an innovator looking to contribute to national security while receiving substantial government funding, understanding the TDF Scheme is your first step toward turning your prototype into a deployable defence solution.
What is the TDF Scheme?
The Technology Development Fund (TDF) is a programme of the Indian Ministry of Defence executed by DRDO. It provides grant-in-aid to Indian industries, particularly MSMEs and Startups, to develop defence and dual-use technologies. The scheme aims to create a bridge between the armed forces, research institutions, and the private sector to foster indigenous innovation and reduce import dependency on foreign defence equipment .
Key objectives of the TDF Scheme
The TDF Scheme is not just about funding; it is about building an ecosystem. Its core objectives are:
- Self-reliance: Promote indigenous design and development of defence technology to align with the 'Make in India' and 'Self-reliant India' campaigns .
- MSME and startup engagement: Specifically encourage the participation of private industries, especially MSMEs and Startups, in the defence R&D ecosystem .
- Niche technology development: Focus on the research, design, and development of niche technologies that are being developed for the first time in the country .
- Bridging gaps: Create a collaborative framework amongst the Armed Forces, academia, DRDO, and private industries .
- Prototype development: Support futuristic technologies that have a Proof of Concept (PoC) and help convert them into viable prototypes ready for induction .
Latest updates and key statistics (2025-2026)
To establish authority and freshness, here are the latest developments regarding the TDF Scheme:
- Enhanced funding: The government has increased the maximum funding per project from Rs. 10 Crore to Rs. 50 Crore .
- Project portfolio: Until December 2024, 80 projects worth approximately Rs. 335 Crore were sanctioned. Overall, around 264 projects amounting to roughly Rs. 930 Crore have been approved under DRDO’s grant-in-aid policies .
- Success rate: 18 technologies developed under TDF have been successfully transferred to users. By 2022, over 70 projects had been awarded for more than Rs. 291 Crore .
- DARPA-like model: In 2025, a new scheme modelled on DARPA (US) was added to the TDF framework to fund cutting-edge research .
TDF scheme eligibility criteria
Before applying, entities must ensure they meet the strict eligibility criteria set by DRDO :
| Eligible entity | Key requirements |
| Industry type | Public/Private Ltd, Partnership, LLP, One-Person Company, or Sole Proprietorship registered in India. |
| MSME/Startup focus | Preference is given to MSMEs (with Udyog Aadhar) and DPIIT-recognized Startups. |
| Ownership | Must be owned and controlled by a Resident Indian Citizen. |
| Foreign investment | Entities with more than 49% foreign investment are not eligible. |
| Collaboration | Can work with academia/research institutions (academia share cannot exceed 40% of project cost). |
| Startup tenure | For nascent startups, they must be incorporated for less than three years and incubated at a government-assisted incubator. |
Funding and financial support
The TDF Scheme is designed to de-risk R&D for private players by providing substantial financial support
- Project cost: Up to Rs. 50 Crore.
- Funding percentage: Up to 90% of the total project cost is covered by Grant-in-Aid.
- Project duration: Typical development period is 2 years, which can be extended up to 4 years for big-ticket projects.
- Milestone-based releases:
- Reimbursement Model: Paid in up to 5 instalments upon successful milestone achievement.
- Advance model: Advance funding available against a bank guarantee.
How to apply for the TDF Scheme
The application process is completely digitised to ensure transparency .
- Registration: Visit the official TDF portal (tdf.drdo.gov.in) and complete the registration process for your industry/startup.
- Profile approval: Once registered, verify your email and submit your profile for approval from the TDF admin panel.
- Identify open projects: Browse the "Projects Open for Application" section. These are specific problem statements or technology gaps identified by the Services (Army, Navy, Air Force).
- Submit EoI: Submit an Expression of Interest (EoI) for the chosen project. Note: Submission of EoI does not guarantee a Project Definition Document (PDD) issuance.
- Detailed Project Report (DPR): If shortlisted, the industry must submit a comprehensive DPR, including technical specs, milestones, and financial breakdowns.
- Evaluation: A three-tier evaluation process assesses Design Capability, Manufacturing Capability, Commercial Viability, and Company Profile.
Benefits of applying for the TDF Scheme
Why should an MSME or startup opt for the TDF Scheme instead of private funding?
- Financial grant: Non-dilutive funding (Grant-in-Aid) up to Rs. 50 Cr.
- IPR ownership: Joint ownership of Intellectual Property Rights (IPR) along with DRDO.
- Technological handholding: Access to DRDO’s labs, experts, and testing facilities for mentoring.
- Market access: Direct sales opportunities to defence primes and a channel for dual-use technology in the private market.
- Ecosystem integration: Opportunity to be a part of the elite national defence ecosystem.
Challenges and considerations
While the scheme is lucrative, applicants should be aware of the challenges :
- Rigorous evaluation: The selection process is highly competitive and technical.
- Compliance: Strict adherence to milestones and certifications (like CEMILAC for airborne systems) is mandatory.
- Timelines: Delays in clearance for large-scale production have been reported in the past.
- Emerging tech gap: Critics note that the scheme initially lacked substantial progress in deep tech like Quantum Computing and AI, though this is now being addressed.
Conclusion
The TDF Scheme represents a monumental shift in India's defence manufacturing landscape. By offering up to Rs. 50 crore in funding, joint IPR ownership, and direct mentorship from DRDO, it provides a strong financial and strategic foundation—much like understanding business loan eligibility, comparing a business loan interest rate, or planning repayments using a business loan EMI calculator before applying for a business loan. It creates a structured pathway for MSMEs and startups to scale innovation. If you have a disruptive idea or a proof of concept in niche technology, exploring the TDF Scheme could be the catalyst that transforms your innovation into a national asset.
