Russia has completed the modernization of the INS Sindhurakshak at its shipyard in Severodvinsk.
INS Sindhurakshak is a diesel electric submarine and has undergone a mid-life refit programme.
During the two year in-depth moder4nisation programme, INS Sindhurakshak has been upgraded to be equipped with the tube-launched Club‑S cruise missiles which are effective against surface vessels and submarines at a range of about 200 km. The submarine has also been fitted with a few Indian components like the hydro-acoustic “USHUS” complex, a CCS-MK radio-communication system and Porpoise Electronic Support Measures.
The INS Sindhurakshak is the seventh and the last of the kilo class diesel electric submarines under active duty of the Indian Navy. These submarines were purchased from Russia during 1986 & 2000. Of the remaining three submarines one was repaired in India and the two others are currently under repair in India.
Even as Russia prepares to deliver the last retrofitted submarine to India, Russia’s top shipbuilding official has come up with the idea of a second mid-life repair of the Indian Navy’s Kilo-class submarines.
A second mid life upgrade of the submarine will add another 5 to 7 years of life to the already 20-year service life. This will help the Indian Navy maintain its submarine strength in view of delays in the induction of French-built Scorpene subs and in floating a tender for six more diesel-electric submarines.
Apart from the modernization of India’s existing submarine fleet, an RFI has been issued for new generation submarines. Russia is expected to take part in the tender with its new Amur-1650 submarines, along with France’s Scorpio, Germany’s Type-214 and Spain’s S‑80 submarines. Russia hopes that it’s submarines stands a good chance of winning the Indian tender.
The Amur-1650 makes far less noise than the Kilo-class submarines, which the NATO nicknamed “Black Holes” for their stealth qualities.
