INS Jyoti

INS Jyoti

INS Jyoti was a fleet replenishment tanker of the Indian Navy commissioned in the late 1960s that provided underway replenishment, logistic support, and fuel resupply to surface combatants and auxiliaries. Commissioned during a period that included the Indo-Pakistani War of 1965 aftermath and Cold War naval expansion, she served alongside other Indian platforms and participated in regional deployments, goodwill visits, and exercises with navies such as the Royal Navy, United States Navy, Soviet Navy, Royal Australian Navy, and navies of Sri Lanka, Maldives, and Mauritius. As a support asset, she interfaced with carriers, destroyers, frigates, and auxiliaries from fleets including those of Japan, France, Russia, United Kingdom, and United States.

Design and capabilities

The ship was designed by Mazagon Dock Limited and naval architects influenced by tanker concepts used by the Royal Fleet Auxiliary and Soviet Navy auxiliary designs, combining fuel storage, transfer rigs, and limited stores handling to support blue-water operations. Her hull form and displacement enabled transfers compatible with aircraft carrier platforms such as the INS Vikrant (R11) class and destroyer classes like the Rajput-class destroyer and Kashin-class destroyer derivatives; she supported underway replenishment alongside Leander-class frigate and Godavari-class frigate escorts. Propelled by steam turbines, she reached speeds adequate to keep station with task groups including battle squadrons similar to those centered on INS Vikramaditya and escorted by Khukri-class corvette elements. Defensive fittings and communications suites allowed integration with command nodes such as Western Naval Command, Eastern Naval Command, and multinational task forces like Operation Cactus and Exercise Malabar.

Construction and commissioning

Constructed at Mazagon Dock Limited in Mumbai, she was laid down and launched in the 1960s, a period of Indian shipbuilding growth that followed collaborations with Soviet Union shipyards and procurement through entities like Hindustan Shipyard Limited. Commissioning ceremonies involved senior officers of the Indian Navy and dignitaries from the Ministry of Defence (India), reflecting strategic priorities established after incidents such as the 1961 Annexation of Goa and contemporaneous with procurement of platforms like INS Vikrant (R11), INS Viraat, and INS Kolkata (D64). The crew complement included sailors trained at establishments such as the Naval Dockyard (Mumbai), Naval Academy (India), and institutions like INS Mandovi and INS Shivaji.

Operational history

Throughout her service life, she operated in the Indian Ocean region, supporting operations and deployments that connected Indian maritime strategy with partners from the United States and Soviet Union during the Cold War and post-Cold War collaborations. Deployments included sustained presence missions, fleet tanker duties during peacetime patrols, and logistic support during contingencies involving regional actors such as Pakistan Navy, Sri Lanka Navy, and maritime security operations in areas near Gulf of Aden, Strait of Malacca, and the Bay of Bengal. She took part in exercises and port visits coordinated with fleets including the Royal Navy, United States Navy, People's Liberation Army Navy, French Navy, and Royal Malaysian Navy, supporting platforms like INS Delhi (D61), INS Mysore (C60), and INS Shakti (A57).

Modifications and refits

Over decades she underwent periodic overhauls at shipyards such as Cochin Shipyard and Mazagon Dock Limited, receiving updates to auxiliaries, pumping systems, fuel lines, and navigation equipment to remain interoperable with evolving replenishment-at-sea standards used by NATO navies and the Soviet Navy legacy systems. Communications and electronic suites were modernized to interface with tactical data systems and satellite links from providers linked to establishments like Indian Space Research Organisation assets and regional tracking centers. Structural maintenance addressed wear from long deployments and tropical corrosion common to vessels operating in the Indian Ocean Region.

Incidents and notable deployments

Her service record included notable deployments and incidents: participation in multinational exercises such as Exercise Malabar and bilateral exercises with the Royal Australian Navy and French Navy; logistic support during humanitarian and evacuation operations similar in scope to Operation Sukoon and Operation Raahat; and port visits to capitals including Colombo, Male, Port Louis, Durban, Aden, Muscat, and Mumbai. During peacetime operations she transferred fuel to combatants during transits comparable to operations alongside INS Vikramaditya and frigate squadrons; sporadic engineering casualties required emergency repairs in yards like Visakhapatnam Naval Dockyard and temporary assistance from tugs such as those from Dredging Corporation of India. Her regional presence contributed to maritime diplomacy with states including Mauritius, Seychelles, Oman, Indonesia, and Thailand.
