India has reportedly initiated development work on an indigenous 105mm cannon intended for the Zorawar Light Battle Tank programme, marking another significant step in the country’s long-term effort to reduce dependence on imported defense systems and strengthen domestic armored vehicle capabilities under the Atmanirbhar Bharat initiative. According to reports, development activities have already commenced with the objective of operationalizing the locally designed gun system within the next five years. The weapon is expected to eventually replace the imported Belgian-origin 105mm rifled gun integrated into the current Zorawar prototype, which uses the Cockerill 3105 turret supplied by John Cockerill Defense. The Zorawar programme, jointly developed by the Defence Research and Development Organisation (DRDO) and Larsen & Toubro (L&T), was accelerated following military tensions along the Line of Actual Control with China, particularly in Eastern Ladakh, where the Indian Army identified the need for a highly mobile light tank capable of operating in mountainous and high-altitude terrain. Initial production batches of approximately 59 tanks are expected to retain the imported turret and gun system to meet immediate operational requirements and avoid delays in induction timelines. However, subsequent variants are likely to incorporate higher levels of indigenous content, including the domestically developed main armament system currently under development. Engineers involved in the programme are expected to focus on critical challenges such as recoil management, thermal stability, lightweight construction, firing accuracy in extreme climates, and compatibility with modern NATO-standard 105mm ammunition including APFSDS, HEAT, and programmable multi-purpose rounds. Future integration of anti-tank guided missile firing capability may also be explored. The indigenous gun programme aligns with the Indian Army’s phased procurement strategy, under which a larger second-phase acquisition of nearly 300 additional Zorawar tanks could follow successful user evaluations. The programme also reflects a broader doctrinal shift toward highly mobile armored platforms optimized for high-altitude operations rather than traditional heavy tank warfare in plains and desert sectors.
