MoD approves 107 Major Line Replacement Units/Sub-systems for Indigenisation
In continuous pursuit of self-reliance in defence manufacturing and to minimise imports by DPSUs under ‘Aatmanirbhar Bharat’, Ministry of Defence has approved another list of 107 strategically important Line replacement Units (LRUs)/sub-systems with a timeline beyond which there will be an embargo on their import.
These will be indigenised in the coming years and will only be procured from Indian Industry after the timelines indicated against each of them in the list. The DPSU-wise and timeline-wise lists are given below:
