After the independence and the partition of India on 15 August 1947, the ships and personnel of the Royal Indian Navy were divided between the Dominion of India and the Dominion of Pakistan. The division of the ships was on the basis of two-thirds of the fleet to India, one third to Pakistan. The operational ships of the remaining Royal Indian Navy, minus Pakistan, were initially placed under the command of the Commodore Commanding Indian Naval Squadron, later the Rear-Admiral Commanding Indian Naval Squadron, whose title was then changed to Flag Officer Indian Fleet. These appointments were initially held by British officers: Commodore H.N.S. Brown, who was the Commanding Officer of and serving as COMINS, seemingly at the same time, and later, Commodore Geoffrey Barnard who became COMINS and later Rear-Admiral Commanding, INS. The Flotilla was later upgraded to the Indian Fleet under a Flag Officer Commanding Indian Fleet. On the proclamation of a Republic in 1950, the 'Royal' title was dropped and the Navy became simply the Indian Navy. Barnard was succeeded by Rear Admiral N.V. Dickinson, Rear Admiral F.A. Ballance, and then the final British officer Rear Admiral St John Tyrwhitt as FOCIF. In 1956, Rear Admiral Ram Dass Katari became the first Indian flag officer, and was appointed the first Indian FOCIF on 2 October, when he took over from Rear Admiral Tyrwhitt.. In 1957, was commissioned, and the flag of Rear Admiral Katari was transferred, INS Mysore thus becoming the flagship of the Indian Fleet. On 1 March 1968, the Eastern Naval Command was established and the Indian Fleet was renamed as the Western Fleet. In September 1971, Rear Admiral S H Sarma was summoned by the Chief of the Naval Staff, Admiral S M Nanda who told him that he was to move to Visakhapatnam and take up command of the yet-to-be-formed Eastern Fleet. The two-fleet concept of the Navy came into force with the constitution of the Eastern Fleet on 1 November 1971. Rear Admiral Sarma took over as the founding Flag Officer Commanding Eastern Fleet. In mid 1971, The Aircraft carrierINS Vikrant, along with the frigates INS Brahmaputra and INS Beas were moved from the Western Fleet to the Eastern Naval Command. Thus, INS Vikrant became the flagship of the Eastern Fleet.
