The rescue team had yesterday extricated badly charred bodies of five of the 18 personnel trapped in the craft after gruelling efforts as naval authorities voiced worst fears that others on board might have been incinerated too.
"Body of one more sailor was recovered from the submarine late this evening," Navy sources said.
The divers had managed to open a second access to the sunken vessel during an overnight operation.
18 Navy personnel, including three officers, were on board the Russia-made submarine when a devastating fire ripped through the frontline underwater craft following serial explosions on Tuesday midnight.
The Navy has instituted a Board of Inquiry to probe the cause of the explosions and fire which is expected to submit its report within four weeks.
Mumbai Police have also registered a case of accidental death in connection with the worst peacetime tragedy suffered by the Navy.
