The government of Tamil Nadu has identified land parcels for the Defence Industrial Corridor. The five nodes include -- Chennai, Coimbatore, Hosur, Salem and Tiruchy -- which form the ‘Defence Quadrilateral’. Around 1,500 acre have been identified between Hosur and Nallampalli in Dharmapuri.
Also, a memorandum of understanding (MoU) was signed between the Defence Research and Development Organisation (DRDO) and the Tamil Nadu Industrial Development Corporation (TIDCO).
The project will create an ecosystem where industries will be encouraged to take up more defence projects. The government is planning a Research and Development (R&D) centre in the Tamil Nadu Defence Corridor, where industries will be hand-held and groomed by Indian scientists.
In January 2019, an investment of over Rs 3,100 crore was announced by the Ordnance Factory Board/Departmental Public Sector Undertakings and private industries for the Tamil Nadu Defence Corridor. Further, the government has also appointed a consultant for preparation of a detailed project report (DPR) for the defence corridor.
