"There are offers from some countries, such as Singapore, with its Swift Rescue vessel, and also some rescue ships to find submarines in trouble under water," TNI spokesman Maj. Gen Achmad Riad informed the press at the Ngurah Rai Air Base here on Thursday.
Singapore's rescue vessel will arrive on April 24, while Malaysia's submarine rescue ship Mega Bhakti will arrive on April 26.
Some other countries, including the United States, Germany, France, Turkey, India, Russia, and Australia, have also extended help to find the submarine that went missing on Wednesday (April 21).
The National Search and Rescue Agency (Basarnas) and the National Transportation Safety Committee (KNKT) will also join the search and rescue operation.
"They will conduct the search in a joint team with the Agency for the Assessment and Application of Technology (BPPT) and Basarnas using Basarnas' ship," he stated.
The German-built KRI Nanggala 402 was scheduled to conduct live torpedo exercises when it sought permission to dive. It began to dive at 3:45 a.m. local time, and the last contact was established at 4:25 a.m. local time when the commander of the exercise was ready to give authorization to launch the torpedo.
Some 53 crew members were aboard the vessel believed to be in waters about 700 meters deep.
Currently, five warships and a helicopter have arrived at the area to look for the submarine, while another warship is en route to the location. The operation has involved 400 TNI personnel. Related news: Indonesia asks Singapore, Australia to assist in submarine search
