Answer: Defence Research and Development Organisation (DRDO)
Notes: Recently, the Defence Ministry called the Advanced Towed Artillery Gun System (ATAGS) project an "exemplary mission mode success". Indigenously made ATAGS will replace vintage and smaller-calibre artillery guns in the Indian Army. ATAGS is a large-calibre gun system capable of firing future Long Range Guided Munitions (LRGM) with precision and deep strike. It has been designed and developed by Armament Research and Development Establishment (ARDE), a Pune-based lab under Defence Research and Development Organisation (DRDO).
