Official beginning of the Army Ordnance in India is marked by establishment of the Board of Ordnance at Fort Williams, Calcutta on 08 April, 1775 by the East India Company under recommendations of Lt Gen Sir John Clavering. The Ordnance Corps of Indian Army traces its roots to this institution. This also marked the beginning of India’s indigenous military production which later led to establishment of the Gunpowder Factory at Ichhapore in 1787 and the Gun Carriage Agency at Cassipore in 1801 which started production in 1802 – on a day that is celebrated as Indian Ordnance Factory Day. 18 March is a date which pulses with the heartbeat of our nation’s self-reliant defence spirit! At present there are 41 ordnance factories which represent over two centuries of indigenous firepower, evolving from British-era necessities into the backbone of India’s military might. It will be a befitting tribute to recount their journey, achievements, and potential synergies for our National emergence.
