The Indian Army has successfully upgraded its legacy Bofors FH-77B howitzers by replacing the outdated Volvo engine with a modern Cummins engine, enhancing their operational reliability, mobility, and logistical efficiency. This initiative, executed at the 506 Army Base Workshop, not only addresses the obsolescence of the original engine but also promotes standardization across artillery systems, aligning with India’s push for self-reliance in defense. The upgraded howitzers have undergone rigorous trials, demonstrating improved performance, reduced maintenance needs, and greater reliability in diverse environments. This move significantly extends the service life of these critical artillery assets while minimizing dependence on foreign suppliers.
