An Indonesian naval ship named KRI Teluk Jakarta-541 carrying out logistical duties sank to a depth of about 90 meters in East Java province's Masalembo waters on Tuesday at about 8:30 a.m.
The Indonesian Navy said that the ship sank due to several leaks at thru-hulls of the vessel in a statement on Wednesday.
"The sea waves (around) the location were between 2.5 and 4 meters high at the time," the statement read.
No casualties were reported in the accident. All the 55 crewmen have been rescued by two civilian ships nearby.
