What’s impeding Indonesia’s military ambitions? May 10 The Indonesian Navy submarine KRI Nanggala takes part in a drill off Cilegon, Indonesia, on Oct. 3, 2017. (AP) MELBOURNE, Australia — The recent loss of a 40-year-old Indonesian submarine has highlighted the need for the Southeast Asian nation to replace many of its military platforms, but plans to do so have been stymied by budget shortfalls and a lack of adherence to its long-term vision. The sinking of the KRI Nanggala in late April, along with the deaths of 53 personnel onboard during a torpedo-firing exercise, prompted debate among Indonesia defense analysts about the state of its armed forces. In particular, some worried about the continued use of aging equipment such as the German-built Type 209 submarine, which was in its fourth decade of service when it sank for unknown reasons.
