March 18

The origins of India's ordnance factories date back to March 18, 1802, when the first government-run gunpowder mill was established. Ordnance factories across the nation open their doors to the public with exhibitions of artillery, small arms, and ammunition. Technical seminars and career fairs are held to inspire the next generation of engineers and technicians in defense research. Ceremonies honor the workforce responsible for producing critical military equipment and supporting national security. The day highlights India's journey toward self-reliance in defense production and the technological innovations achieved over two centuries.
