    Indian Navy Kilo Class submarines upgrade


    Overhaul, sensor and weapon upgrade including Club-S missiles
    The Indian Navy (IN) is in the process of upgrading its 10 Kilo class submarines under a deal signed in 2001.

    Each upgrade costs $80 million and involves a complete overhaul of the submarine and its hull structures; installation of an improved control system, sonar, electronic warfare system, and an integrated weapon control system.

    Four submarines have already been overhauled at the Zvezdochka shipyard, which is getting ready to overhaul the fifth - INS Sindhurakshak - under a deal which is expected to be signed in spring 2010.

    The submarine will be delivered to Severodvinsk in June 2010.

    The IN Project 636 / Kilo class submarine fleet comprises the following subs.

    Name Commission Date
    INS Sindhughosh S55 30 April 1986
    INS Sindhudhvaj S56 12 June 1987
    INS Sindhuraj S57 20 October 1987
    INS Sindhuvir S58 26 August 1988
    INS Sindhuratna S59 22 December 1988
    INS Sindhukesari S60 16 February 1989
    INS Sindhukirti S61 4 January 1990
    INS Sindhuvijay S62 18 March 1991
    INS Sindhurakshak S63 24 December 1997
    INS Sindhushastra S65 19 July 2000

    Club-S Missiles

    All the 10 subs are also being retrofitted with Club-S submarine cruise missile family.

    The Club-S 3M-54E1 is a subsonic sea skimming (100') anti-ship missile which accelerates to supersonic speeds during its terminal phase covering the last 15 km in less than 20 seconds, making if difficult for anti missiles defenses to engage it.

    The missile can be launched from a 533 mm torpedo tube from a depth of 35 to 40 meters (130 feet). It can also be launched from a vertical launch tube.

    It uses an ARGS-54 active radar seeker and Glonass satellite and inertial guidance.

    Club-S 3M-54E1
    Weight 4,400 lb
    Warhead 440 lb
    Range 300 km
    Terminal Speed 3,000 kph

    INS Sindhugosh and INS Sindhuvijay have already been equipped with the Club-S cruise missile systems.

    The upgrade wasn't smooth. After INS Sindhuvijay was upgraded, six test firings of the Club-S missile in 2007 failed and India refused to accept the submarines which spent two years in Russia. The technical glitches were eventually sorted out.

    The Zvezdochka shipyard said on Wednesday it will install Club-S cruise missile systems on four Kilo class diesel submarines in service with the Indian navy in the next five years.

    "The new missile system will be installed on the INS Sindhuratna, INS Sindhuraj, INS Sindhushastra, and INS Sindhuvir. The retrofit will be carried out at Indian shipyards," the shipyard in northern Russia said in a statement.

    The Kilo-class submarine is thought to be one of the most silent submarine classes in the world. It has been specifically designed for anti-shipping and anti-submarine operations in relatively shallow waters.

    Displacement.......2,300 tons
    Max Dive Depth.......350 m (1,200')
    Range..............6,000 miles
    Crew..................57
    Armament.......... 2x533
    Max Surface Speed 10 kts
    Max Submerged Speed 17 kts

    Russia has built Kilo-class submarines for India, China and Iran.

    yes their duration will be extended by around 5 years but because submarines have to go through a lot of wear and tear over their lifespans, lifespans are never guaranteed. I dont think these subs will make it to 2020, if they have to then they will require another refit around the 2015 year mark.

    Retirement of subs start from 30 years of service.so kilo would start retireing in 2016 when the first sub inducted in 1986 would be retired. Likewise it fully decommisned in 2026

    its a private company,and they r now separating the unit associated with the defense sector as a new subsidiary which will only get associated with defence products

    L@T is the second biggest engineering and manufacturing enterprise in India
