A video has emerged showing the crew of the sunken Indonesia submarine singing a ballad together on board the vessel.
The video was filmed a few weeks before KRI Nanggala 402 went down with 53 sailors on board.
Some of those who perished are seen in the video recorded as a farewell for the outgoing commander of the navy's submarine corps, reported AFP.
They were singing an Indonesian hit song, Sampai Jumpa, which translates to "Till we meet".
"Even though I'm not ready to be missing you, I'm not ready to live without you," they sang.
The video has been watched more than 1.2 million times on Instagram after it was out for more than two days.
The poignant lyrics have hit home, with many commenters leaving sad face emojis.
Tributes continue to pour in
Submarine commander Lieutenant Colonel Heri Oktavian was among those gathered around one of the seamen strumming the acoustic guitar.
