On 21 April 2021, an Indonesian navy submarine called KRI Nanggala (402) was reported as missing in waters about 95 km (51 nautical miles) north of Bali during its torpedo drill.[6][7] Few days later, debris was found within 10 nmi (19 km; 12 mi) of the point of last contact and was believed to have come from the submarine. Nanggala was later declared sunk along with 53 people on board, including 49 crew members, 1 commander, and 3 weapons specialists.[8][9]
