Indian Ordnance Factories Service (IOFS): Recruitment, Functions, Hierarchy and Pay Scales

The Indian Ordnance Factories Service (IOFS) is one of the Group ‘A’ services you can get into once you clear the UPSC civil services exam. It is a unique service in that it is the only cadre in which officers are recruited by all four methods – civil services exam, engineering services exam, interviews and promotions. Officers of this service engage in the management of the Indian Ordnance factories. These factories engage in the production of defence equipment and arms/ammunition. In this service, there are two types of posts – technical and non-technical. The technical (engineering) posts are filled by the ESE whereas the non-technical posts are filled by the CSE. Read on to know more about the IOFS functions, hierarchy and salaries.

A brief history of IOFS

The history of the Indian ordnance factories dates back to the British Raj. The British East India Company required military hardware for establishing and maintaining their economic supremacy in India and for this, in 1775, the British authorities established the Board of Ordnance at Fort William, Calcutta. The first factory came up at Ishapore in 1787 and it produced gunpowder. The Indian Ordnance Service was established in 1935 and it had only European officers then. This was reconstituted as the Indian Ordnance Factories Service (IOFS) in the year 1954 with the Defence Department as its cadre controlling authority.

Training for IOFS officers

After the initial Foundation Course at LBSNAA, the officer trainees are provided training in the areas of management, public administration and technology at the National Academy of Defence Production (NADP), Nagpur. This Induction Training Programme is for 64 weeks. After this, they are sent on a Bharat Darshan wherein they visit defence, space, nuclear, industrial and other technical installations. Then, the officers are imparted on-the-job training at the Ordnance Factories.
