iDEX Prime Re-Open is a high-value defence innovation challenge launched under the Innovations for Defence Excellence (iDEX) framework by the Defence Innovation Organisation (DIO), Ministry of Defence. This re-launch features two advanced problem statements issued by the Indian Air Force (IAF), aimed at developing mission-critical defence technologies through collaboration with MSMEs, startups, and individual innovators.
Under the iDEX Prime category, selected innovators qualify for grant support of up to ₹10 crore to develop and demonstrate advanced prototype systems aligned with operational requirements. The first challenge focuses on the development of a UAS-based Electronic Support Measures (ESM) system for SIGINT operations in hilly terrain and high-altitude areas. The system is expected to integrate tethered drones mounted on vehicle platforms, ELINT payloads, encrypted SATCOM data transmission, real-time localisation of adversary electronic warfare emitters, and operational capability up to 4 km AMSL. The expected project outcome is a fully integrated vehicle-based SIGINT system capable of enhancing electronic warfare capabilities in near real-time operational scenarios.
The second challenge under iDEX Prime X seeks the development of an inflatable or modular all-weather sun shelter for fighter aircraft and helicopters. The solution must be rapidly deployable, modular, transportable across difficult terrain, resistant to harsh weather, fire-retardant, thermally insulated, and equipped with HVAC systems. It must also incorporate features to reduce enemy satellite-based surveillance exposure. The shelter should support operations up to 4.5 km AMSL and be scalable for larger aircraft classes.
Through structured evaluation, pitch sessions, and milestone-based monitoring, iDEX Prime enables the development of strategic indigenous defence technologies with significant operational impact. The program strengthens India's defence innovation ecosystem by supporting high-value, deep-tech solutions aligned with national security priorities.
