Indian Navy ranks and insignia

[2] In May 1949, Lord Mountbatten, the inaugural Governor-General of India and himself a naval officer, dispatched a note to Prime Minister Jawaharlal Nehru, titled Names and Insignia of Indian Armed Forces, containing a list of suggestions regarding the nomenclature of the armed forces that were to be enforced upon the dominion's conversion to a republic.

[2] In September 1949, Nehru forwarded the proposals to the country's minister of defence, Baldev Singh, recommending Mountbatten's suggestions, which were consequently enforced upon India's emergence as a republic on 26 January 1950.

[6][7] Consequently, the revision plan was publicized during the IN's 2023 Navy Day celebrations, when prime minister Narendra Modi announced that the rank structure's designations would be retitled with domestic names to reflect Indian-origin traditions, while the shoulder board epaulettes worn by flag officers would be altered to bear the octagonal-shaped naval crest, which had been adopted by the IN the previous year.

[5] Accordingly, the alterations to the flag officer insignia were revealed later that month; notably, other observable emendations in the new insignia included the introduction of an Indian sword-cum-telescope design in lieu of the older sword-cum-baton design and a gold button embossed with a clear anchor in lieu of a fouled anchor.

[11] However, unlike the IA and the IAF, which both bear the honorary five-star ranks of Field Marshal (FM) and Marshal of the Indian Air Force (MIAF) respectively, the IN does not have a correspondingly recognized equivalent, as no four-star admirals were deemed for promotion to five-star rank.
