INS Jyoti (A58) (meaning: sacred light) is the third of the four Komandarm Fedko-class replenishment oilers.^[3] 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^[7] until INS Vikramaditya (R33) was commissioned in November 2013. Its primary role is fleet replenishment and sustaining blue-water operations.^[3] It was later fitted with close-in weapon systems for self-defence.^[2][8]

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.^[2][5][6][9]

Design and description

General characteristics and propulsion

INS Jyoti has a length of 178 m (584 ft) overall, a beam of 25.3 m (83 ft) and a draft of 11.35 m (37.2 ft). The ships displaces about 35,900 tonnes (35,300 long tons; 39,600 short tons) at full load. The complement is about 208, including 23 officers.

The ship is powered by a steam turbine providing a power of 10,948 hp (8,164 kW). This allows the ship to reach a maximum speed of 15 knots (28 km/h; 17 mph) and an endurance of 12,000 nautical miles (22,000 km; 14,000 mi) ^[3]

Capacity

Displacing 39,900 tons at full load, Jyoti is the second largest ship of the navy, even larger than the 28,500 tons aircraft carrier INS Viraat. The ship can carry 28,000 tons at full load, consisting of fuel diesel, aviation fuels, oils, and water of different grades. The fresh water carried for use in steam turbines is of much higher grade than drinking water.^[5][6][9]

Jyoti has two replenishment positions on each side, with the option of stern refueling and can replenish three ships simultaneously. It can refuel at the rate of 300 tonnes per hour.^[10][11] It has a range of 12,000 nautical miles at the top speed of 15 knots. It has a double-skin hull, which prevents sea pollution in case of damage to any fuel tank, and carries eco-friendly equipment on board to prevent marine and environmental pollution. The space between the double-hull is used for ballast tanks. The fuel and water levels in the cargo tanks are checked to maintain the ship's stability during loading and discharging of supplies.^[5][6][9]

Armament

It was initially armed with light and medium machine guns. In 2000, self-defence capability was added by installing new close-in weapons like anti-aircraft and anti-missile guns and missiles. This was done to enhance the survivability of the ship during surface warfare operations on India's western seaboard. It also has a helicopter deck.^[5][6]

Procurement and service

INS Jyoti 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 was commissioned on July 20, 1996.

Service history

INS Jyoti

1998

Growth in the India-Philippines relations broadened ways for the cooperation between navies. Three Indian naval ships - INS Delhi, INS Khanjar and INS Jyoti visited the Philippines from 24-27 October 1998.^[12]

On 28 March 1998, four civilian workmen were killed in a gas explosion on-board Jyoti at the naval dockyard.^[5]

2001

INS Jyoti and INS Mumbai were deployed to South East Asia and South West Pacific. The ships made port calls at Fremantle, Sydney, Wellington and Ho Chi Minh City.^[13]

2003

INS Jyoti visited the Shanghai naval base in 2003 as part of a three-vessel fleet, for a five-day official visit. The fleet was commanded by flag officer Rear Admiral R. P. Suthan of India's Eastern Naval Command. It comprised a guided missile destroyer INS Ranjit, a guided missile corvette INS Kulish and Jyoti. The fleet held airborne and surface search and rescue exercises with China's East Sea Fleet, which were code-named Dolphin 0311. Before the joint exercise, the Chinese and Indian ships also conducted maritime communication and formation maneuvers. These were the first joint naval exercises between China and India. The fleet left Shanghai on November 14, 2003.^[14][15][16]

2007

In early 2007, a fleet of ships from the navy's Eastern command conducted a two-month-long deployment in the South-East and East Asia. The ships, guided-missile destroyers INS Mysore, INS Rana and INS Ranjit, the guided-missile corvette, INS Kuthar and the fleet tanker INS Jyoti, were under the command of Flag Officer Commanding Eastern Fleet, Rear Admiral R K Dhowan. From March 18 to May 23, the fleet made port-calls at a number of ports, including Singapore, Yokosuka in Japan, Qingdao located on the southern coast of the Shandong peninsula of China, Ho Chi Minh City in Vietnam, and Vladivostok in Russia. The fleet left Qingdao on April 16, 2007,^[17] and then conducted joint anti-terror exercises with the Russian Navy.^[5][18]

During September 2007, the navy deployed three ships - INS Delhi, INS Beas and INS Jyoti on a four-day goodwill mission to Oman, to strengthen maritime relations and develop maritime cooperation. The deployment was led by Rear Admiral Shekhar Sinha, Flag Officer Commanding of Western Naval Command.^[19]

INS Jyoti in 2009

In 2009, Jyoti, along with INS Mumbai, INS Ranvir and INS Khanjar took part in an international fleet review at Qingdao, conducted by the China's People's Liberation Army Navy (PLAN) on its 60th anniversary. Twenty one naval vessels from 14 nations and delegations from 29 countries took part in the review, which lasted from April 20 to 24.^[20][21][22] The fleet then proceeded to Okinawa in Japan, and took part in Malabar 2010 with the US Navy's Seventh fleet and the Japanese Maritime Self-Defense Force.^[23] The other ships were USS Blue Ridge, guided missile destroyers USS Fitzgerald and USS Chafee, fast-attack submarine USS Seawolf of the US Navy, and two guided-missile destroyers, including JDS Asayuki of the JMSDF, along with various P-3C and SH-60 aircraft. The exercise involved air defence, anti-submarine and surface warfare.^[24]

By 2010, the ship had completed thirteen years in the navy, during which it had undertaken 2504 underway replenishment runs and travelled 375,282 nautical miles. It had operated in the Indian Ocean, South China Sea, Red Sea, Persian Gulf and the Pacific Ocean and has participated in numerous multinational exercises with the navies of United States of America, South Korea, Philippines, Japan and Singapore etc.^[3]

In April 2010, it took part in the 17th Singapore-Indian Maritime Bilateral Exercise (SIMBEX) with the Singapore Navy. SIMBEX-2010 was held in the Andaman Sea and the Bay of Bengal. Five platforms of the Indian Navy took part, INS Batti Malv, a fast-attack craft and INS Mahish, a landing ship tank from the Andaman & Nicobar Command, destroyer INS Ranvir, the tanker INS Jyoti and a submarine from the Eastern Naval Command. Singapore Navy was represented by two ships, RSS Intrepid, a Formidable-class frigate and RSS Victory, a Victory-class corvette. During the exercise, Jyoti simultaneously refueled INS Ranvir and RSS Intrepid. The fleet later called at Port Blair and Visakhapatnam.^{[25][26][27][28]}

In May 2010, the navy’s Eastern Fleet deployed INS Jyoti, along with guided-missile destroyers INS Rana and INS Ranjit and missile corvette INS Kulish from Port Blair to South East Asia, where the fleet undertook passage exercises with the navies of Indonesia, Singapore and Australia.
