New Delhi: Kalyani Strategic Systems Limited (KSSL), a wholly-owned subsidiary of Bharat Forge under the prestigious Kalyani Group, has embarked on a ground breaking initiative to develop a 155mm/52-calibre tracked self-propelled howitzer (SPH) based on the indigenously developed Advanced Towed Artillery Gun System (ATAGS). This strategic move represents a significant advancement in India’s defence manufacturing capabilities and positions KSSL as a key player in the global artillery market while strengthening India’s pursuit of self-reliance in defence production.
The ATAGS represents a pinnacle of indigenous defence manufacturing, developed by the Defence Research and Development Organisation (DRDO) in collaboration with KSSL and Tata Advanced Systems Limited (TASL). This 155mm/52-calibre towed howitzer has achieved remarkable specifications that position it among the world’s most advanced artillery systems.
The ATAGS boasts an impressive range of 48 kilometres with base bleed ammunition, significantly exceeding the performance of most contemporary artillery systems globally. The system features advanced automation capabilities, including a fully electric drive system that ensures maintenance-free and reliable operations over extended periods. With a firing rate of 5-6 rounds per minute and the ability to achieve Multiple Round Simultaneous Impact (MRSI) firing, the ATAGS provides exceptional battlefield effectiveness.
The system’s sophisticated features include autonomous operation capabilities, integration with the Artillery Combat Command and Control System (ACCCS-Shakti), and compatibility with NavIC-guided smart ammunition. These technological advancements make the ATAGS an ideal foundation for developing a tracked self-propelled variant, as the core systems can be adapted to a mobile platform while maintaining their advanced capabilities.
KSSL’s decision to develop a tracked SPH based on the ATAGS platform is driven by several strategic considerations. The Indian Army’s Field Artillery Rationalisation Plan (FARP), conceived in 1999, envisages the acquisition of approximately 2,800 155mm artillery guns by 2027, including a significant number of self-propelled systems. This massive modernisation program presents substantial opportunities for domestic manufacturers who can deliver world-class systems that meet the Army’s stringent requirements.
The company’s experience with the truck-mounted Multi-terrain Artillery Gun (MArG) system has provided valuable insights into mobile artillery development. The MArG, unveiled at international defence exhibitions, demonstrates KSSL’s capability to successfully adapt towed artillery systems to mobile platforms while maintaining their operational effectiveness. This experience forms a crucial foundation for developing a tracked SPH that can offer superior mobility and survivability compared to towed systems.
