Eastern Naval Command

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 Surface Fleet of the Navy was called Indian Fleet and was commanded by the Flag Officer Commanding Indian Fleet (FOCIF). Initially, the shore establishments on the eastern coast were headed by a captain in the appointment of Naval Officer-in-Charge, Vishakapatnam (NOIC). This was subsequently upgraded to the appointment of Commodore East (COMEAST), a One Star appointment. The FOCIF and COMEAST reported into the Chief of the Naval Staff. In July 1967, COMEAST was upgraded to the two-star appointment of Flag Officer, East Coast (FOEC). On 1 March 1968, the Eastern Fleet was also created. With this, the appointment of FOEC was re-designated Flag Officer Commanding-in-Chief Eastern Naval Command (FOC-in-C ENC). The Indian Fleet was split between the Western Fleet and the Eastern Fleet with the Fleet Officer Commanding Eastern Fleet (FOCEF) reporting into the FOC-in-C ENC. On 1 March 1971, Vice Admiral Nilakanta Krishnan took over as FOC-in-C, the first three-star officer to lead the command.

The oldest naval establishment of the Eastern Seaboard was the INS Circars, Visakhapatnam, which was identified as "an important convoy assembly point" for the Royal Indian Navy flotillas. A small Naval Base was established there on 12 December 1939 and the base was designated as HMIS Circars on 12 April 1942. Now, the base is the base depot ship of the Eastern Naval Command. It is the logistics and administrative support establishment of the Command, supporting all ships and units based in Visakhapatnam. As of 2018, the establishment supports 52 additional units with strength of 2,300 sailors and 400 officers, besides accommodating live-in sailors of Circars.

Under the Flag Officer Commanding-in-Chief Eastern Naval Command (FOC-in-C East) is the Flag Officer Commanding Eastern Fleet (FOCEF), Commodore Commanding Submarines (East) (COMCOS (E)), Admiral Superintendent Dockyard for Visakhapatnam, shore establishments, and five Naval Officers-in-Charge (NOICs).

The Eastern naval Command has the states of Andhra Pradesh, Odisha and Tamil Nadu etc., under its area of responsibility.

The FOC-in-C (East) is the submarine operating authority, under whom COMCOS (E) operates. The 11th (Sindhughosh class submarine) and 8th (Foxtrot class) Submarine Squadrons operate under COMCOS (E). INS Virbahu, a submarine base commissioned on 19 May 1971, is the alma mater of the Indian Navy submariners.

The Eastern Naval Command is organized as follows:

The headquarters in Visakhapatnam, is also a strategically important dockyard for two nuclear-powered submarines of the Arihant-class submarine. Due to congestion and heavy shipping traffic, a new 20 square km base INS Varsha is being developed for exclusive naval use about 50 km south of Visakhapatnam.

The Eastern Navy fleet is distributed among its bases at Paradip, Tuticorin, Kakinada and Chennai on the east coast, and in the Andaman and Nicobar Islands. The Navy has opened its latest naval air base, INS Baaz, at the southernmost tip of the Andaman and Nicobar Islands to secure the strategically important Straits of Malacca, and another naval air station in Kolkata to base an unmanned aerial vehicle squadron.

In 2005, Eastern Naval Command was home to 30 warships. Since then it has grown to include INS Jalashwa is the flagship of Eastern Fleet and provides amphibious capabilities to the Indian Navy in the Bay of Bengal. Eastern Fleet is equipped with submarine pens and maintenance dockyards. The Amphibious Task Group of Eastern Naval Fleet has INS Jalashwa (LPD), INS Vikrant (Aircraft carrier) It's CBG includes the Delhi-class & Rajput-class destroyers, Nilgiri-class & Shivalik-class frigates, Arnala-class, 2 Kora-class, Kamorta-class & Khukri-class corvettes, Sindhughosh-class submarines, Airhant-class (SSBNs) and the Akula-class submarine INS Chakra. Naval aviation is provided by Westland Sea King, MH-60R, Kamov-31 & Kamov-27 helicopters. For Fixed-wing aircraft it's P-8I and Mig-29K naval fighters. Apart from these, a number of smaller vessels such as Patrol Vessels, fast attack craft, support vessels and other auxiliary ships.

Until 1997, INS Vikrant (1961) was the flagship of Eastern Fleet. After her de-commissioning in 1997, the Eastern Fleet has been without an aircraft carrier. Its aircraft carrier capability will get restored after first indigenously built aircraft carrier INS Vikrant (2013) joins the Eastern Fleet by 2023 after completing extensive sea trials and is likely to based in Vishakapatnam.
