Countries from around the world are offering support to help locate and rescue the crew.
Time is short: The sub was only equipped with 72 hours of oxygen and may be too deep for rescue.
Countries from around the world are sending reinforcements to assist in the search for a Indonesian naval submarine that went missing on Wednesday.
The 53-person crew was participating in a torpedo drill north of Bali but failed to relay the results of the drill, an Indonesian Navy spokesperson told Reuters. Hadi Tjahjanto, the commander of the Indonesian National Armed Forces, said the submarine lost contact with the military at 4:30 a.m. local time on Wednesday.
