This was then called the Indian Fleet. After her commissioning in 1948, HMIS Delhi (later called INS Delhi) became the Flagship of the Indian Fleet. The Fleet commander was styled as Flag Officer Commanding Indian Fleet (FOCIF).
In 1956, Rear AdmiralRam Dass Katari became the first Indian flag officer, and was appointed the first Indian Commander of the Fleet on 2 October, when he took over from Rear AdmiralSirSt John Tyrwhitt.[4][5] In 1957, INS Mysore was commissioned and the flag of Rear Adm Katari was transferred from INS Delhi to INS Mysore, thus becoming the flagship of the Indian Fleet.[6]
The first Aircraft carrier of the Indian Navy, INS Vikrant was commissioned in 1961 and became the flagship of the Indian Fleet.[7]
At the outbreak of war, the Western Fleet was commanded by Rear Admiral E C Kuruvilla, PVSM, AVSM.[11] 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.[12] Due to this, INS Mysore, once again, became the flagship of the Western Fleet.
On 4 December, the fleet successfully executed Operation Trident, a devastating attack on the Pakistan Naval Headquarters at Karachi that sank a minesweeper, a destroyer and an ammunition supply ship. The attack also irreparably damaged another destroyer and oil storage tanks at the Karachi port.[15] To commemorate this, 4 December is celebrated as the Navy Day.[16] This was followed by Operation Python on 8 December 1971, further deprecating the Pakistan Navy's capabilities.[15]
The Indian Navy launched Operation Talwar on 25 May 1999. The entire Western Fleet had sailed from Mumbai to the North Arabian Sea to increase surveillance and adopt a deterrent posture. Elements of the Eastern Fleet joined the Western Fleet in the Arabian Sea later. The joint Western and Eastern Fleets blockaded the Pakistani ports (primarily the Karachi port).[18][19][20][21][22] They began aggressive patrols and threatened to cut Pakistan's sea trade. This exploited Pakistan's dependence on sea-based oil and trade flows.[23] Later, then-Prime Minister of Pakistan, Nawaz Sharif disclosed that Pakistan was left with just six days of fuel to sustain itself if a full-scale war had broken out.[24][25][26][27]
