In 2021, Government having corporatise the functions of the 41 Indian Ordnance Factories into 7 Defence Public Sector Undertakings (DPSUs), the Government is merging them again in 2024, as the output of one factory serves as the input of the other.

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 () in the year 2020–'21.

Every year, 18 March is celebrated as the Ordnance Factory Day in India.

History Origins The Indian Ordnance Factories predate 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 and 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.

Contributions 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, aluminium, copper plants of India, 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.

Restructuring OFB into seven DPSUs On 17 June 2021, the Defence Ministry announced its plans to split the existing five operating divisions of OFB, in addition to parachutes and opto-electronics, 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:

Advanced Weapons and Equipment India Limited (AWE) Armoured Vehicles Nigam Limited (AVANI) Gliders India Limited (GIL) India Optel Limited (IOL) Munitions India Limited (MIL) Troop Comforts Limited (TCL) Yantra India Limited (YIL)

The new companies were launched and dedicated to the nation on 15 October 2021.

The Government is exploring the possibility of merging five of the seven defence public undertakings as of 2023, as the output of one factory serves as the input of the other.

Training institutes, regional centres and controllerates

National Academy of Defence Production provides training to the IOFS officers in areas of technology, management, public administration as induction and re-orientation courses.

There were Ordnance Factories Institutes of Learning (OFILs) in Ambajhari, Ambernath, Avadi, Dehradun, Ishapore, Khamaria, Kanpur and Medak. Each OFIL was headed by a principal director, and NADP by a senior principal director. NADP provided training to Group A officers, whilst the other eight institutes imparted training to Group B and Group C employees of the ordnance factories. OFB had Regional marketing centres and Regional controllerates of safety as well.

Joint ventures In 2017, the Department of Defence Production under the Ministry of Defence opened itself to for Joint Ventures with OFB and DRDO was also tasked with identifying their products and patents, with the scope of commercial production

Indian Ordnance Factories Service (IOFS)

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.

Products The type of ordnance material produced is very diverse, including various small arms to missiles, rockets, bombs, grenades, military vehicles, armoured vehicles, chemicals, optical devices, parachutes, mortars, artillery pieces plus all associated ammunition, propellants, explosives and fuses.
