Ordnance Factory Board (OFB), consisting of the Indian Ordnance Factories, now known as Directorate of Ordnance (Coordination & Services) was an organisation, under the Department of Defence Production (DDP) of Ministry of Defence (MoD), Government of India. The 41 Indian Ordnance Factories have been converted into 7 Defence Public Sector Undertakings (DPSUs).
OFB was the 37th-largest defence equipment manufacturer in the world, 2nd-largest in Asia, and the largest in India.OFB was the world's largest government-operated production organisation, and the oldest organisation in India. It had a total workforce of about 80,000. It was often called the "Fourth Arm of Defence", and the "Force Behind the Armed Forces" of India. Its total sales were at US$3 billion (₹22,389.22 crores) in the year 2020–'21.
It was engaged in research, development, production, testing, marketing and logistics of a product range in the areas of air, land and sea systems. OFB consisted of forty-one ordnance factories, nine training institutes, three regional marketing centres and four regional controllerates of safety, which are spread all across the country. Every year, 18 March is celebrated as the Ordnance Factory Day in India.
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 also 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 of India, established the first engineering colleges of India, as its training schools, sparked India's first war of independence in 1857 with its rifles and bullets, and also played key role in the founding of research and industrial organisations like ISRO, DRDO, BDL, BEL, BEML, SAIL, etc.
On 17 June 2021, the Defence Ministry announced plans to restructure OFB into seven PSUs wholly owned by the government. It was mentioned that all existing factories and employees will become a part of these seven PSUs. From 1 October 2021, OFB has been dissolved and all the management, control, operations and maintenance has been transferred to 7 newly formed Defence PSUs, namely:
The new companies were launched and dedicated to the nation on 15 October 2021 by Prime Minister Narendra Modi.
The Apex Board was headed by the Director General of Ordnance Factories (DGOF), who acts as the Chairman of the board (ex officio Secretary to Government of India) and consisted of nine other members, who each held the rank of Additional DGOF. Ordnance factories were divided into five operating divisions, depending upon the type of the main products/technologies employed. These were:

Main article: Indian Ordnance Factories Service
The Indian Ordnance Factories Service (IOFS) is a civil service of the Government of India. IOFS officers are Gazetted (Group A) defence-civilian officers under the Ministry of Defence.
IOFS is a multi-disciplinary composite cadre consisting of technical – engineers (civil, electrical, mechanical, electronics), technologists (aerospace, automotive, marine, industrial/product design, computer, nuclear, optical, chemical, metallurgical, textile, leather) and non-technical/administrative (science, law, commerce, management and arts graduates). Technical posts account for about 87% of the total cadre. The doctors (surgeons and physicians) serving in OFB belong to a separate service known as the Indian Ordnance Factories Health Service (IOFHS). IOFHS officers are responsible for the maintenance of health of the employees, and the hospitals of OFB. They report directly to the IOFS officers. IOFS and IOFHS are the only two civil services under the Department of Defence Production.
