The Flag Officer Defence Advisory Group (FODAG) and Advisor Offshore Security and Defence to the Government of India is the title of the flag officer who heads the Offshore Defence Advisory Group. The FODAG is a two-star officer holding the rank of Rear Admiral. The current FODAG is Rear Admiral A. V. Bhave, VSM. History
The Oil and Natural Gas Commission (ONGC) discovered an oilfield in the Gulf of Khambhat in the early 1970s, called the Mumbai High Field. Later in the decade, more oilfields were discovered in the western offshore region. These economic assets need to be kept under surveillance and require continuous protection. The Indian Coast Guard (ICG) came into being on 19 August 1978. Among the Coast Guard's charter of duties was the safety and protection of artificial islands and offshore terminals. The responsibilities for the safety and protection of the offshore installations were discussed between the Indian Navy, ONGC and the Indian Coast Guard. As a result, an offshore security coordination committee (OSCC) was established in 1978. Subsequently, on 31 December 1983, an Off shore Defence Advisory Group (ODAG) was established. The ODAG was to be headed by a Rear Admiral designated Flag Officer Defence Advisory Group (FODAG). The FODAG would plan and advise the Navy and ONGC on the security and defence of the offshore installations. On 25 June 2002, offshore defence advisory cells were established at Visakhapatnam  and New Delhi. The FODAG was re-christened Flag Officer Defence Advisory Group and Adviser Offshore Security and Defence to the Government of India. Functions and role
