Komandarm Fedko-class oiler

The Komandarm Fedko class is a class of replenishment tankers operated by the Indian and Chinese navies. Four ships of the Komandarm Fedko class were constructed by the Soviet Union, later Russia, of which one was bought by India, one by China and two are in commercial service. INS Jyoti (meaning "light") is the third largest ship in the Indian Navy after the aircraft carrier INS Vikramaditya.

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 commissioned on 20 July 1996. The ship was based at Bombay, where it arrived in November 2006. It is deployed as 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 nmi to 50 days and 16,800 nmi. INS Jyoti visited Shanghai in 2003, and participated in exercises by the Indian and Singapore navies in 2010.

Qinghaihu was laid down in January 1989 at the Kherson Shipyard as Vladimir Peregudov. In 1992, China bought the incomplete ship from Ukraine for $10 million. The ship sailed nearly complete to Dalian, China in 1993, and completed by the Dalian Shipbuilding Industry Company. She was commissioned into the PLAN on 5 August 1996 and assigned to the South Sea Fleet.
