The Defence Research and Development Organisation (DRDO) is advancing the development of a sub-15-ton variant of the Advanced Towed Artillery Gun System (ATAGS), named the Advanced Light Towed Artillery Gun System (ALTGS), with internal trials expected by late 2026. This new design aims to provide the Indian Army with a high-mobility artillery solution suited for challenging terrains, featuring a reduced chamber size and a lighter barrel while retaining all-electric drive technology for enhanced reliability. The Indian Army may require up to 1,200 units over the next 15 years, which would replace outdated artillery systems. If successful, the ALTGS could establish India as a leader in lightweight artillery technology, surpassing existing global competitors.
