DEVELOPMENT OF SHAPE MEMORY ALLOYS FOR 30 MM LINKS
Stage
FEASIBILITIES
Overview
To develop indigenous Shape Memory Alloy (SMA)-based materials for 30 mm ammunition links that offer improved strength, resilience, and re-usability under extreme operational conditions, ensuring better performance during high-rate firing and battlefield deployment. 30 mm ammunition links are critical components used to hold and feed rounds into automatic cannons. Conventional materials face deformation and fatigue under repeated thermal and mechanical stress, especially in rapid-fire scenarios. Shape Memory Alloys possess the unique ability to return to their original shape after deformation, offering potential for enhanced reliability, reduced wear, and self-correcting alignment.

DEVELOPMENT OF UNDERWATER RE-USABLE TARGET FOR ANTI- SUBMARINE TORPEDOES
Stage
FEASIBILITIES
Overview
To develop a robust, cost-effective, and re-usable underwater target system for simulating submarine signatures and movement profiles. This will support effective testing, calibration, and training with anti-submarine torpedoes under realistic operational conditions. Anti-submarine warfare (ASW) capability is a critical component of naval defence.Presently, expendable or imported targets are used for testing torpedoes, which are either non-reusable or financially unsustainable. There is a need for an indigenous,re-usable underwater target that can emulate various submarine characteristics and be deployed repeatedly across naval ranges for extended use.

Project Name
DEVELOPMENT OF ALTERNATE RECHARGEABLE BATTERIES FOR PRACTICE TORPEDO
Stage
FEASIBILITIES
Overview
To design and develop an indigenous, cost-effective, and rechargeable battery system as an alternative to existing imported or non-reusable power sources used in practice torpedoes for naval training and evaluation exercises.Practice torpedoes are used extensively in anti-submarine warfare (ASW) training to simulate real engagement scenarios. These torpedoes rely on onboard power sources for propulsion, control, and data logging. Current batteries are either imported or non-rechargeable, leading to high operational costs and logistical challenges. Developing a reliable and rechargeable battery system will significantly reduce lifecycle costs and improve operational readiness.

Project Name
DEVELOPMENT OF INDIGENOUS CUSTOMER PREMISES EQUIPMENT (CPE) FOR SECURE INTERNET FOR ONBOARD NAVAL SHIPS (SIFON)
Stage
FEASIBILITIES
Overview
To design and develop an indigenous, secure, and ruggedized Customer Premises Equipment (CPE) system to enable encrypted and reliable internet connectivity onboard Indian naval ships under the Secure Internet for onboard Naval Ships (SIFON) framework in coordination with TSP. With increasing digitalization of naval operations, secure internet access at sea has become a mission-critical requirement. SIFON aims to provide encrypted and authenticated internet services to Indian warships while maintaining operational secrecy and cybersecurity. Current solutions rely on commercial or imported hardware, which may pose security risks and are not tailored for naval environments. An indigenous CPE designed to meet naval requirements is vital for secure maritime connectivity.

Project Name
DESIGN AND DEVELOPMENT OF MULTI-FUNCTIONAL ANTENNA FOR NAVAL APPLICATIONS
Stage
FEASIBILITIES
Overview
To design and develop an indigenous, compact, and high-performance multi-functional antenna system capable of supporting communication, navigation, surveillance, and electronic warfare across multiple frequency bands for naval platforms including ships, submarines, and UAVs. Naval platforms require multiple antennas for various tasks like SATCOM, GPS, UHF/VHF communication, radar, and EW. However, separate antennas for each function result in space constraints, mutual interference, increased maintenance, and high radar cross-section. A unified multi-functional antenna can resolve these challenges by integrating multiple capabilities into a single low-profile system.

PURIFICATION OF METALS SUCH AS Indium (In), Gallium (Ga), Antimony (Sb) etc. TO SEMICONDUCTOR GRADE i.e. 7N+
Stage
FEASIBILITIES
Overview
To develop an indigenous, cost-effective, and scalable process for purifying critical metals like In, Ga, and Sb to semiconductor-grade purity 99.99999 + (7N+), meeting the stringent requirements of the electronics and strategic defence sectors. Ultra-high purity metals are essential raw materials for semiconductors, optoelectronics, solar cells, and compound semiconductor devices. India presently depends heavily on imports for 6N–7N+ grade metals, which poses a strategic risk. Developing indigenous purification capabilities for these critical materials is vital for self-reliance in the electronics supply chain.

DEVELOPMENT OF DILUTION REFRIGERATOR
Stage
FEASIBILITIES
Overview
To indigenously develop a dilution refrigerator system capable of achieving temperatures below 15 mK for quantum computing applications & to support cutting-edge quantum technology research, ultra-low temperature experiments, and defence-related applications. Dilution refrigerators are the only practical systems capable of cooling below 15 mK, enabling breakthroughs in quantum computing, superconducting circuits, low-temperature detectors, and fundamental physics experiments. Currently, India relies entirely on imported systems, which are expensive, restricted by international regulations, and challenging to maintain. Developing this technology indigenously will position India as a key player in the global cryogenic and quantum research ecosystem.
