Technology Development Fund (TDF)

What is the Technology Development Fund?

Technology Development Fund (TDF) is a Ministry of Defence programme executed by the Defence Research and Development Organisation (DRDO) to fund the indigenous development of defence components, products, systems and technologies by Indian industry. Technology Development Fund sits within the Government of India's "Make in India" push in defence and is aimed squarely at reducing import dependence for critical defence subsystems.

According to the TDF portal run by DRDO, funding is released as grant-in-aid covering up to 90% of the project cost, with a ceiling of Rs 50 crore per project. That ceiling was raised from the earlier Rs 10 crore limit, which allowed the scheme to take on substantially larger development projects than before.

Technology Development Fund is not a subsidy or a welfare payment. It is a competitive R&D funding route: DRDO publishes specific technology requirements as project calls, industry submits proposals against those calls, and the selected developer builds the technology with DRDO mentoring.

Key objectives

• Build indigenous capability in defence technologies currently imported.
• Bring MSMEs and start-ups, not only large defence primes, into defence R&D.
• Reduce the cost of defence production and improve quality and functionality.
• Create a supplier base that defence primes and the armed forces can buy from.

Main features

• Grant-in-aid of up to 90% of project cost, capped at Rs 50 crore per project.
• The applicant industry contributes the remaining share of the project cost.
• Intellectual property is held jointly by the industry partner and DRDO.
• Industry partners get access to DRDO laboratories, experts and test facilities.
• Industry may work in a consortium with another company or with academia, but the work involvement of academia cannot exceed 40% of the total project.
• Projects are advertised on tdf.drdo.gov.in and marked "Open for Application".

Who is eligible for the Technology Development Fund?

An entity can apply if:

• It is an Indian company, firm, MSME or DPIIT-recognised start-up, or an academic institution participating in development.
• It is owned and controlled by resident Indian citizens, with majority Indian ownership of at least 51%.
• It has demonstrable R&D capability or potential, and can meet DRDO's technical and financial evaluation parameters.
• It is responding to a project currently listed as Open for Application on the TDF portal.

Who cannot apply:

• Individuals cannot apply for Technology Development Fund as a personal benefit. There is no citizen application and no individual cash grant. A private innovator with an idea should look instead at DRDO's separate "Dare to Dream" innovation contest.
• Entities with more than 49% foreign investment are not eligible, since the scheme requires Indian ownership and control.
• Entities that cannot show a credible R&D base or that fail DRDO's financial due diligence are not eligible.
• Proposals unrelated to any published TDF project call are not considered; Technology Development Fund funds against specific advertised requirements, not open-ended ideas.

This is the single most misunderstood point about the scheme. Technology Development Fund is institutional defence R&D funding. Salaried professionals, students and ex-servicemen looking for a personal grant will not find one here.

What documents are required for the Technology Development Fund?

How to apply for the Technology Development Fund

1. Open the official portal at tdf.drdo.gov.in and register your company, MSME or start-up with its registration details and authorised signatory.
2. Browse the list of projects and identify one marked Open for Application that matches your technical capability.
3. Read the project description, deliverables and timeline published with that call, and confirm your entity meets the ownership and eligibility conditions.
4. Prepare the technical proposal; approach, work-breakdown structure, milestones, test plan and the team assigned to the project.
5. Prepare the financial proposal, a detailed cost estimate showing the grant-in-aid sought and your own contribution, since DRDO funds up to 90% of project cost.
6. Upload the proposal along with incorporation documents, Udyam or DPIIT recognition, audited financials and the shareholding pattern, then submit online before the closing date of that call.
7. Attend the technical and financial evaluation conducted by DRDO, including any presentation or clarification the evaluation committee asks for.
8. On sanction, sign the agreement with DRDO and draw grant-in-aid against milestones as the project progresses.

How much benefit does the Technology Development Fund provide?

Technology Development Fund sanctions grant-in-aid of up to 90% of the project cost, capped at Rs 50 crore for a single project. The applicant industry funds the balance. Money is not paid as a lump sum. It is released against agreed milestones as the technology is developed and demonstrated.

Beyond the cash, Technology Development Fund gives the industry partner three things that are hard to buy: access to DRDO laboratories and test facilities, mentoring by DRDO scientists, and joint ownership of the resulting intellectual property with a clear line of sight to defence customers.

What technology areas does the Technology Development Fund cover?

Project calls published on the TDF portal span the engineering disciplines that defence systems depend on; aerospace and avionics engineering, embedded systems, artificial intelligence, robotics engineering and design engineering, among others. The exact scope of any individual project is fixed by the description in that call, so an applicant should read the call document rather than rely on the broad area label.

How to track a Technology Development Fund proposal

1. Log in to your registered account on tdf.drdo.gov.in.
2. Open the dashboard for the project call you applied against.
3. Check the status shown against your proposal — submitted, under technical evaluation, under financial evaluation, or sanctioned.
4. Respond promptly to any clarification request raised by the evaluation committee, since an unanswered query stalls the file.

Common reasons TDF proposals are rejected

• Ownership failure; more than 49% foreign investment, or control not resting with resident Indian citizens.
• Weak R&D base: no in-house team, facilities or track record to execute the project.
• Financial capacity, the applicant cannot demonstrate the ability to fund its own share of project cost.
• Proposal does not match the call, an interesting technology that does not meet the published requirement is still a mismatch.
• Unrealistic milestones or costing: timelines or budgets that do not stand up to DRDO's evaluation.

Help and contact

• TDF contact numbers: 011-23792825, 011-45660227 and 011-66208011, working days between 9:00 AM and 5:00 PM.

Applying under Technology Development Fund is free. No consultant can guarantee a sanction, and DRDO does not accept proposals outside the published project calls.
