OFB is the world's largest government-operated production organisation,[8] and the oldest organisation run by the Government of India.[9][10] It has a total workforce of about 164,000.[5] It is often called the "Fourth Arm of Defence",[11][12][13] and the "Force Behind the Armed Forces" of India.[14][15] It is amongst the top 50 defence equipment manufacturers in the world.[3][16] Its total sales were at $3 billion (19982.71 crores) in 2015-'16.[2] Every year, 18 March is celebrated as the Ordnance Factories' Day in India.[17][18]




The history and development of the Indian Ordnance Factories is directly linked with the British reign in India. The East India Company considered military hardware to be a vital element for securing their economic interest in India and increasing their political power. In 1775, the British East India company accepted the establishment of the Board of Ordnance at Fort William, Calcutta. This marks the official beginning of the Army Ordnance in India.

In 1787, a 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.[19]


The growth of the Ordnance Factories Board leading to its present setup has been continuous but sporadic. There were eighteen ordnance factories before India became independent in 1947 and twenty-three factories have been established after independence, mostly in the wake of defence preparedness imperatives brought about by the wars involving India.

  • 1801 – Establishment of Gun Carriage Agency at Cossipore, Kolkata.
  • 1802 – Production begins at Cossipore on 18 March.

Indian Ordnance Factories ServiceEdit

The Indian Ordnance Factories Service (IOFS) (Hindi: भारतीय आयुध निर्माणी सेवा) 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 (Chemical, Metallurgical, Textile, Leather) and non-technical/administrative (Science, Law, Commerce, Management and Arts graduates). Technical posts comprise 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.[21]


The recruitment in the Indian Ordnance Factories as a Group A officer is done by the Union Public Service Commission (UPSC) based on the performance in the rigorous and prestigious Engineering Services Examination (ESE) and the Civil Services Examination (CSE).[22] Engineering posts are filled through the Engineering Services Examination, while technologists are selected through interviews by UPSC. Posts in the non technical streams are filled through the Civil Services Examination. IOFS is the only cadre in which candidates are selected by all four means – CSE, ESE, interviews and promotions. IOFHS officers are selected through the Combined Medical Services Examination, conducted by UPSC.[23][24][25] All appointments to the Group A Civil Services are made by the President of India.[26]
