The term “indigenisation of technology” goes beyond just manufacturing the item based on drawings and materials supplied by a foreign manufacturer (OEM). Here, the local manufacturer is expected to understand the technology underlying the product or part, so as to be able to change, modify, improve or re-design the item as and when he likes. Most of the ‘technology transfer’ that takes place in the Indian defence and aerospace sector, only relates to the manufacture of the item within the country and therefore concerns only the technology involved in manufacturing. The foreign manufacturer rarely provides any insight into the technology for design or modifications of the part.
