Innovation for Defence Excellence (iDEX) Scheme

Current Affairs & Government Schemes › Defence and Security Current Affairs · Topic 21.4

Innovations for Defence Excellence (iDEX) is a Ministry of Defence scheme, launched in April 2018 and run by the Department of Defence Production, that funds start-ups, MSMEs, individual innovators and research bodies to build new technology for the armed forces. It is implemented by the Defence Innovation Organisation, a not-for-profit company set up by Hindustan Aeronautics Limited and Bharat Electronics Limited. The armed forces and defence public sector units post problem statements through the Defence India Startup Challenge, and winners get grants, mentoring and a chance of purchase. The ADITI scheme, launched in March 2024, offers larger grants for critical technologies.

Where Does It Fit?

This topic describes the start-up and innovation route inside the policy of defence indigenisation. It shows how the services state their needs and let small firms propose solutions. Previous topic: Defence Indigenization and Atmanirbhar Bharat in Defence Production. Next topic: Agnipath Scheme and Agniveer Recruitment Reforms.

How Does iDEX Work?

Stage	What happens
Problem statements	The armed forces and defence public sector units list real technology needs, such as drones, sensors, communication and cyber tools
Challenge	The Defence Innovation Organisation opens a Defence India Startup Challenge, or DISC, and start-ups, MSMEs, innovators and academic bodies apply
Selection	A committee picks the best proposals and the winners sign an agreement with a partner incubator
Funding	Winning firms get a grant for prototype development, with different ceilings under iDEX and under iDEX Prime
Trials	The prototype is tested by the service that raised the problem
Procurement	If trials succeed, the service can buy the product, and a start-up with a contract gets a first customer

iDEX main: grants of up to about Rs 1.5 crore for early stage prototype work, through partner incubators
iDEX Prime: launched in 2022 to give larger grants, from about Rs 1.5 crore to Rs 10 crore, to firms with a more advanced product
ADITI: Acing Development of Innovative Technologies with iDEX, launched on 4 March 2024, offers grants of up to Rs 25 crore for critical and strategic technologies and was backed by an outlay of Rs 750 crore, as reported
Open Challenge: besides DISC, a separate route allows firms to propose solutions without a posted problem
Technology Development Fund: a DRDO scheme that funds MSMEs and start-ups for projects of higher cost than the iDEX grants, with higher grant limits in recent years

What Else Should You Remember?

Parent body: the Defence Innovation Organisation is a company under the Companies Act set up by HAL and BEL, and works under a board headed by the Defence Production Secretary
Budget: the Government approved a budget for iDEX for the five years from 2021-22 to 2025-26, as reported
Contracts: reports put the number of contracts signed in the several hundreds, with prototypes worth thousands of crores cleared for purchase. Figures differ between sources, so use them as approximate
Latest challenge: new DISC and ADITI rounds with over 100 problem statements were reported in 2026
Links with indigenisation: products from iDEX feed the import-banned lists described in Defence Indigenization and Atmanirbhar Bharat in Defence Production
Link with procurement: faster routes for innovation procurement are discussed in Defence Acquisition Procedure (DAP) and Defence Procurement Reforms
Examples of fields: drones and counter-drone systems, secure communication, surveillance, artificial intelligence tools and space-based sensing, as reported
Challenge: many prototypes do not become orders because trials are slow and the buyer needs budget and approvals
Concern: a start-up needs working capital after winning a grant, and delays in contracts hurt young firms most

Why Does It Matter for the Exam?

Full name: the name is Innovations for Defence Excellence and the scheme belongs to the Department of Defence Production
Implementer: the Defence Innovation Organisation and its setup by HAL and BEL
Windows: iDEX, iDEX Prime and ADITI differ in grant size
Year: 2018 for launch and 2024 for ADITI
Common errors: crediting DRDO with running iDEX, or mixing it with the DRDO Technology Development Fund

As an analytical point, iDEX works when the buyer commits to purchase. A grant helps a start-up build a prototype, but only an assured order lets it grow, so faster trials and simpler contracts decide the success of the scheme.
