April 23, 2021 By Ann Koh and Arys Aditya (Bloomberg) The Indonesian navy’s missing submarine may have been too old and overloaded when it embarked on a military exercise on Wednesday, according to a defense analyst. The KRI Nanggala-402 that disappeared in waters off Bali island was carrying 53 crew during training, Indonesia’s defense ministry said. A submarine of that class has a maximum capacity of 40, according to Ridzwan Rahmat, principal defense analyst at Janes. Its age does not help either. At over 40 years, the Cold War-era submarine is among the world’s oldest in service today and was not built to withstand pressure beyond 230 meters (754 feet) deep, Ridzwan said.
