Currently, Indonesia is in grief again. Various disasters seem to constantly shake our country. After in early January the Sriwijaya plane crashed in the kepulauan Seribu, floods in several areas, earthquakes in Malang and its surroundings, and now the submarine belonging to the Indonesian Navy, KRI Nanggala 402, sank.  KRI Nanggala 402 was initially reported to have lost contact on April 21, 2021. The last time KRI Nanggala was able to communicate at 04.30 WIB. After that the KRI Nanggala could not be contacted again and was declared drowned. Many people believe that the cause of this sinking was due to the many defects in the submarine's old engine. Therefore, there are three main reasons why Indonesia needs to modernize and improve the Main Tool of the Defense System (Alat Utama Sistem Pertahanan or Alutsista).
