List of active Indonesian Navy ships

All the Indonesia Navy (Indonesian: Tentara Nasional Indonesia-Angkatan Laut, TNI-AL) vessels are named with the prefix KRI (Kapal Perang Republik Indonesia or Naval Vessel of the Republic of Indonesia). Smaller sized boats with light armaments usually have the prefix KAL (Kapal Angkatan Laut or Naval Vessel of the Indonesian Navy). The classes are often named after lead ships or the first ship commissioned.

The Navy has a traditional naming convention for its ships. Moreover, the ship's type and missions can be identified by the first number on the ship's three-digit hull number, which is located at the bow and the stern of a vessel. The naming convention is such as:^{[1][page needed]}
