The minister indicated that the submarine has not suffered any major damage.
The Minister was asked to comment on the alleged incident where Navy's INS Sindhughosh submarine was allegedly grounded due to lack of water in the harbour area in Mumbai.
Last week on Friday, the submarine had encountered a situation where there was very less water in the harbour but held to its position using ropes and other means but was not grounded, they said.
In August last year, Navy lost its latest submarine INS Sindhurakshak after an explosion in its torpedo section killing all the 18 personnel on board.
