    # INS Sindhukirti was docked in the mid-1990s, and had been under "Medium Refit-cum-Upgradation" since 2003, and by 2014 was expected to return to service no sooner than 2015. But in 2014 media reports indicated that workmanship on the submarine was so bad that Indian Navy had termed it “unfixable” and unlikely to ever enter into service again.

    Indian Navy’s INS Sindhukirti entered its final full-power trials after a decade-long renovation process, before officially re-entering into service with the Indian Navy in July 2015. The attack submarine would provide a much-needed advantage to India’s limited submarine force.

    Sindhukirti is the seventh Sindhughosh-class (Indian name for the Russian Kilo-class) diesel-electric attack submarine in the Indian Navy, which was originally commissioned in 1990. The Sindhukirti entered its upgrade process back in 2006. India’s Sindhughosh-class submarines were co-developed between India and Russia’s Rosvooruzhenie. The Sindhukirti's restoration involved extensive modernization.

    * An internal explosion occurred onboard INS Sindhurakshak around midnight on 13/14 August 2013 in the forward compartment, where ordnance was stowed, resulting in major fire onboard. The submarine remained submerged and resting at the bottom at the Naval Dockyard, Mumbai. INS Sindhukirti is unlikely to enter into service again.
