History
INS Jyoti (A58) was constructed by the Admiralty Shipyard of St. Petersburg, Russia. It was built to be a Project 15966M merchant tanker, but was modified and purchased by the Indian Navy, and got commissioned on July 20, 1996. The ship was based in Bombay, where it arrived in November 2006. It is a major force multiplier in sustaining the navy's blue water operations. It can increase the range of a naval task force without tanker support from seven days and 2400 nautical miles to 50 days and 16,800 nautical miles. INS Jyoti visited Shanghai in 2003, and participated in exercises by the Indian and Singapore navies in 2010.
