The British authorities in 1775 established a Board of Ordnance in Fort William, Kolkata, which marks the official beginning of the Army Ordnance in India. They further set up a gun powder factory in 1787 at Ishapore, which started production in 1791.In 1801, the British established a Gun Carriage Agency at Cossipore, Kolkata and production started on March 18, 1802. This heralded the first industrial establishment of Ordnance Factories in India and they continue to operate till date.
