last rites with military honours. The Navy's preliminary report indicated that "an accident or inadvertent mishandling of ammunition" was the cause of the explosions; the full incident report would only be completed after the submarine was raised. The salvage contract was awarded on 31 January 2014 to Resolve India, a subsidiary of the US-based Resolve Marine Group. The submarine was brought to the surface on 6 June 2014. In December 2014, a naval court of inquiry arrived at the preliminary conclusion that human error as a result of crew fatigue caused the disaster. A senior officer stated that "the crew was working beyond their prescribed hours. Fatigue and exhaustion may have triggered human error that led to the accident. Standard operating procedures were violated at several levels". A 2017 report by the Comptroller and Auditor General of India quoted the Navy's Board of Inquiry stating that "Submarine authorities concerned didn’t properly assess the crew fatigue, besides, the submarine was holding ammunition nearing life expiry". Initially, the navy was hopeful of using Sindhurakshak'' after it was salvaged, but on Navy Day 2015, Vice Admiral Cheema confirmed the Sindhurakshak would be disposed of. After a period of use for the training of marine commandos, the submarine was sunk in 3000 metres of water in the Arabian Sea during June 2017.
