Tamil Nadu has proposed a 3,000-acre aerospace hub near Hosur in Krishnagiri district, close to Bengaluru, to attract manufacturing for the DRDO’s Advanced Medium Combat Aircraft (AMCA) program. Announced on December 9, 2025, the initiative by Tamil Nadu Industrial Development Corporation includes an airport, DRDO research labs, AMCA fighter jet factory, NETRA surveillance center, and high-tech factories across villages like Balavanpalli (788 acres), Muthali (432 acres), and Adavanapalli (498 acres), utilizing government and private lands. Just 40 km from HAL facilities, this positions Tamil Nadu ahead of rivals like Karnataka, boosting self-reliance in defense amid regional threats from China’s aviation advances and driving economic growth through jobs and investments.​
