India’s indigenous Zorawar Light Tank programme is poised for a significant survivability enhancement as the Defence Metallurgical Research Laboratory (DMRL) develops advanced armour solutions designed to counter NATO-standard 25 mm and 30 mm Fin Stabilized Armour Piercing Discarding Sabot (FSAPDS) ammunition.
DMRL officials have revealed that efforts are underway to achieve STANAG Level 5B protection against 25 mm FSAPDS rounds and STANAG Level 6 protection against 30 mm FSAPDS threats. If achieved, the upgrade would considerably strengthen the battlefield survivability of the Zorawar Light Tank, which is being developed as a next-generation armoured platform for operations in high-altitude environments.
The vehicle currently features STANAG Level 4 protection at the front and Level 2 protection on other sections. While this configuration provides defence against heavy machine-gun fire, artillery fragments, and certain autocannon threats, the planned armour package would significantly improve resistance against modern infantry fighting vehicles and combat platforms armed with high-velocity autocannons.
NATO’s STANAG standards serve as globally accepted benchmarks for armoured vehicle protection. Level 5B is generally associated with protection against 25 mm armour-piercing ammunition, while Level 6 is designed to withstand 30 mm APFSDS rounds commonly employed by advanced infantry fighting vehicles and attack helicopters.
The enhanced armour is particularly important for the Zorawar programme because the tank is intended for deployment along India’s northern borders, where potential adversaries field modern armoured vehicles equipped with powerful 30 mm weapon systems. Addressing one of the traditional weaknesses of light tanks—limited protection against medium-calibre kinetic threats—the upgrade aims to deliver higher survivability without compromising mobility.
DMRL’s contribution highlights India’s growing expertise in advanced armour materials, including specialised steels, ceramic composites, and lightweight protection technologies. Balancing protection and weight remains critical, as the Zorawar is designed to operate in mountainous terrain where mobility and rapid deployment are essential.
Jointly developed by DRDO and Larsen & Toubro, the Zorawar Light Tank is being built to meet the Indian Army’s requirement for a highly mobile armoured platform capable of operating in Eastern Ladakh and other high-altitude regions. The need for such a platform became more urgent after the border standoff with China, during which the People’s Liberation Army deployed Type-15 light tanks and other lightweight armoured vehicles in plateau areas.
Beyond domestic requirements, the armour upgrade could also enhance the Zorawar’s attractiveness in the international market. As modern battlefields become increasingly dominated by drones, loitering munitions, precision-guided weapons, and autocannon-equipped vehicles, survivability has become a key factor for light armoured platforms competing in the global defence sector.
