Firstly it was planned to send the submarine to Russia for the upgrade because Hindustan yard has almost zero experience in the field but later on plan changed and decided for an indigenous upgrade.

The  refits take long time as expected because that kind of expertise did not exist in India before and that was the first time that in Indian yard they were trying to refit it.

However instead of so many delays ,After nine years Sidhukiriti was returned to Indian Oceans on 23 May 2015 and currently undergoing sea trails as on 2016.
