The purpose of setting up of IL was to attain self-reliance in C&I field for process industries. After contributing its share towards this objective it was thought proper to utilize the expertise gained in field of high tech electronics and manufacturing facilities in other areas. It was decided to use the expertise gained to help Defence forces in getting the equipment Indigenously. Keeping this in view a separate group was formed to liaison with agencies like MOD, Ordnance factories etc to find out the requirement which IL can design, develop, manufacture and supply meeting the stringent Defence specifications. IL has till now developed and supplied following items to Defence establishments.
