Defence Minister Arun Jaitley and Chief of Naval Staff Robin Dhowan visited Western Naval Command in Mumbai to see the salvaged INS Sindhurakshak that sunk last year in August killing eighteen sailors.
The sailors went missing after weapons stored in the forward section of the Russian-built INS Sindhurakshak exploded in the middle of the night, causing a fire as it lay berthed in Mumbai, the navy's worst losses in more than four decades.
Divers found the bodies of three sailors who were on board.
The submarine was so badly damaged by fire and explosions that it was unlikely that any of 15 other missing crew members would be found alive.
