Brief History


Ordnance Factory Board predates all the other organisations like the Indian Army and the Indian Railways by over a century. The first Indian ordnance factory can trace its origins back to the year 1712 when the Dutch Ostend Company established a Gun Powder Factory in Ichhapur. In 1787, another gunpowder factory was established at Ichapore; it began production in 1791, and the site was later used as a rifle factory, beginning in 1904. In 1801, Gun Carriage Agency (now known as Gun & Shell Factory, Cossipore) was established at Cossipore, Calcutta, and production began on 18 March 1802. This is the oldest ordnance factory in India still in existence.


The Indian Ordnance Factories have not only supported India through the wars, but played an important role in building India with the advancement of technology and have ushered the Industrial Revolution in India starting with the first modern steel plant of India much before Tata Steel, first modern electric textile mill of India, first chemical industries such as smokeless propellant plants of India, established the first engineering colleges of India as its training schools, played key role in the founding of research and industrial organisations like ISRO, DRDO, BDL, BEL, BEML and SAIL.
