INS Jyoti (A58) (meaning: sacred light) is the third of the four Komandarm Fedko-class replenishment oilers. She was modified for naval use and is now being operated by the Eastern Naval Command of the Indian Navy. Jyoti was the largest ship in the navy until INS Vikramaditya (R33) was commissioned in November 2013. Its primary role is fleet replenishment and sustaining blue-water operations. It was later fitted with close-in weapon systems for self-defence.
