Answer: Defence Research and Development Organisation (DRDO)
Notes: Post Operation Sindoor, the Indian Air Force (IAF) is pushing for rapid progress on Project Kusha. Project Kusha, also called Program Long Range Surface to Air Missile (PGLRSAM), was approved in 2022 with a budget of ₹21,700 crore. It is an indigenous initiative led by Defence Research and Development Organisation (DRDO) to develop a long-range air defence missile system. Phase 1 includes four interceptor variants: M1 (range 150 km), M2 (250 km), M3 (350–400 km), and Naval variant (200–300 km). Phase 2 aims to develop an even longer-range interceptor exceeding 600 km. The project strengthens India’s strategic air defence capabilities.
