Expressing hope of reusing the sunken INS Sindhurakshak submarine, the Navy today said its record was "not all that bad" in terms of accidents when compared to other navies in the world.

"These (sinking of INS Vindhyagiri warship and INS Sindhurakshak) are isolated and separate cases. The reasons does not derive their linkage from previous cases. Operational risks are fraught in this business of armed forces.

"I would say that our record is not all that bad. We have had accidents there is no denying but if you compare with other navies...," Navy Chief Admiral DK Joshi said in reply to a query related to sinking of two warships in recent times.

The INS Sindhurakshak had sunk on August 14 in the Mumbai naval harbour after an explosion probably in its torpedo section killing all 18 personnel on board. A Board of Inquiry is still on to find out causes behind the accident.
