Indigenisation of these items will be taken up by DPSUs under ‘Make’ category. ‘Make’ Category aims to achieve self-reliance by involving greater participation of Indian industry. Projects involving design and development of equipment, systems, major platforms or upgrades thereof by the industry can be taken up under this category. DPSUs will offer these identified LRUs/Sub-systems for industry led design and development. This will be a great opportunity for the Indian industry to get integrated in the supply chains of manufacturing major defence platforms.

The indigenous development of these LRUs/Sub-systems projects will bolster economy and reduce the import dependence of DPSUs. In addition, it will help harness the design capabilities of domestic defence industry and position India as a design leader in these technologies.

This list is in continuation to the Positive Indigenisation List of 2,851 sub-systems/Assemblies/Sub-Assemblies/Components which had been earlier notified by Department of Defence Production, Ministry of Defence on December 27, 2021.
