The Indian Navy has started testing a modernised and refitted diesel-electric submarine, the Sindhukirti, in the open seas, N.K. Mishra, head of the Hindustan Shipyard Limited (HSL), told reporters on Friday.
The modernization began in 2006, and took nine years to complete. During this time, the Ushus sonar system, manufactured in India, was installed on the submarine, along with more than 10 other systems of both domestic and foreign manufacture. 100 kms of cables and 30 kms of high-pressure air pipes were replaced during the refit.
“Modernization turned out to be a more complex process than the construction of a new submarine,” the newspaper The Hindu quoted Mishra as saying, on its website. “This was the largest project ever implemented in an Indian shipyard.”
