Advanced Towed Artillery Gun System (ATAGS)
TestingAmogh appeared in the 2026 Republic Day mechanised column while still undergoing induction trials.
On 26 January 2026, the Indian Army paraded the system under the service name Amogh, while an Army officer said it remained under trials for induction. The first product-model gun had been declared ready for mandatory testing in July 2025, with an 18-gun regiment projected within a year of that test. The Ministry of Defence signed contracts worth about Rs 6,900 crore in March 2025 for the guns and 6x6 towing vehicles; the wider procurement covers 307 ATAGS and 327 towing vehicles for 15 regiments. The 155 mm/52-calibre system combines an all-electric drive and automatic ammunition handling with Zone 7 BMCS capability, a stated range beyond 48 km and 18 km/h self-propelled mobility. It matters because the Indian Army's first major private-sector towed-gun purchase replaces smaller vintage guns with a domestically designed long-range system.
