The Indonesian Navy reportedly has about 72 hours worth of oxygen left to rescue the 53 crew members of the Type 209/1300 submarine KRI Nanggala (402), which went missing in deep waters during a torpedo drill north of Bali on Wednesday.
A half-dozen warships, a helicopter, and 400 people are involved in the search while Singapore and Malaysia have dispatched additional assets, and the US, Australia, France, and Germany have offered assistance. The Indian Navy has dispatched their DSRV.
A 40-year-old boat, the German-made SSK underwent a refit in South Korea in 2012. In somber news, Nanggala disappeared in 2,300 feet of water (Type 209/1300s have a test depth of 800 feet) and an oil slick was observed shortly after.
