List of active Indonesian Navy ships

All the Indonesia Navy (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:


 * Hull number beginning with 1 (reserved for aircraft carriers): ancient empires and kingdoms
 * Hull number beginning with 2 (cruisers and destroyers): Indonesia's main islands
 * Hull number beginning with 3 (frigates, ocean escorts, corvettes): national heroes or naval heroes
 * Hull number beginning with 4 (submarines, submarine tenders): mythical weapons (for submarines), national heroes (for submarine tenders)
 * Hull number beginning with 5 (amphibious ships, LSTs, LPDs, LCUs, command ships): strategic bays or gulfs (for LSTs), big cities (for LPDs), small cities (for LCUs), national figures (for command ships)
 * Hull number beginning with 6 (fast attack ships): mythical weapons (previous names for missile boats), traditional weapons (current names for fast missile boats), wild animals (for fast torpedo boats)
 * Hull number beginning with 7 (minesweepers, minehunters ships): every island begin with letter "R", letter "F" (mine countermeasure vessel)
 * Hull number beginning with 8 (patrol boats): native fishes and sea creatures, native snakes and wild reptiles, wild insects, geographical places (such as towns, lakes or rivers begin with "si-", e.g. Sikuda, Sigurot, Sibarau)
 * Hull number beginning with 9 (supporting ships, oilers, tugs, troop transports, oceanographic research ships, sailing ships, etc.): volcanoes, cities, mythical figures, geographical capes and straits

Submarine fleet
The Indonesian Navy is expected to operate at least 8 submarines by 2024. The submarines are named after weapons in Javanese Wayang mythology.

Surface fleet
Surface ship are typically named after a National Hero of Indonesia or other Heroes of Indonesia.

Fast boat fleet
Fast missile boat (FMB) and Fast torpedo boat (FTB) are small vessels that are used in a hit-and-run naval strategy. FMBs are named after traditional weapons of Indonesia. FTBs are named after wild animals.

Patrol fleet
The list below mentions ships that are considered as KRI because they are equipped with heavy and adequate armament or equipment. The Indonesian Navy also has numerous smaller patrol boats that classify as KAL. These types of boats were used as a secondary fleet to maintain the law of Indonesian coastal sea. Most of these smaller boats are lightly armed and better known domestically as PC or Patroli Cepat (Fast Patrol) vessel. There are also even smaller boats with Patkamla (Patroli keamanan laut) prefixes or Marine security patrol and armed with only machine guns. These boats are mainly used to patrol around various TNI AL naval bases or Lanal (Pangkalan TNI AL) across the Indonesian archipelago. Due to the sheer number of Lanal located inside Indonesian territory, TNI AL sources some of its patrol vessels (mostly Patkamla or rarely KAL vessels) from local shipbuilding industry in the region around its bases' location. This resulted in a varied bunch of ship classes and designs based on different standards adopted by various ship builder. Patrol boats are named after fish (Pari class, Sibarau class, Cucut class, etc.), snake (Boa class, Krait class, etc.), and small islands of Indonesia. The list below does not reflect the actual number of patrol vessels used by Indonesian Navy due to various factors, such as insufficient open-source data of some vessels and the lack of coverage by most national or international publications on patrol boats smaller than 18 meters (mostly Patkamla vessel), which are often converted from locally sourced boats near its Lanal location.

Transport/Amphibious Warfare fleet
LSTs with helipads and LPDs with wider flight decks are generally used for transport, whereas the reverse is used for amphibious warfare. LPD is named after a maritime city, while LST is named after a bay.

Frigates
In 2019, defence planners from the Indonesian Ministry of Defence (MoD) are increasingly leaning towards a variant of the Iver Huitfeldt-class frigate in their quest to acquire two more frigates for the country's navy.

On April 30, 2020, The Indonesian Ministry of Defence has signed a preamble contract that paves the way for the country to procure Iver Huitfeldt-class frigate from Denmark. The contract was signed in the presence of representatives from the MoD, state-owned shipbuilder PT. PAL, and PT. Sinar Kokoh Persada, the Indonesian agent for Danish company Odense Maritime Technology (OMT).

In July 2020, it was reported that Indonesian Ministry of Defence has indicated an interest in procuring Germany's Bremen-class frigate warships as part of Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut: TNI-AL) modernization program requirement known as the Interim Readiness Frigate (IRF).

On July 13, 2020, Indonesia's Minister of Defence, Prabowo Subianto, has forwarded a proposal for the country to receive up to $20 billion in defence-related foreign credit and assistance schemes for the period spanning 2020–24. Among programmes that may be funded via the proposed foreign defence credits include two follow-on warships to the Martadinata-class frigate.

According to a statement released by the Indonesian MoD on 31 March 2021, Indonesian state-owned shipbuilder PT. PAL has engaged German naval consultancy group, MTG Marinetechnik, and Turkish engineering firm FIGES AS, to customize the design of a new frigate class that it will be constructing for the Indonesian Navy. Marinetechnik and FIGES are customizing a derivative design of Iver Huitfeldt-class frigate for TNI-AL requirements, and will be recommending a suite of sensors, weapons, and other combat systems for the frigate.

According to The Japan Times and The Japan News, Indonesia plans to import four destroyers and construct four more ships domestically through transfer of technology from Japan. The project is expected to be worth about ¥300 billion and will likely to include the Mogami-class frigate.

On June 10, 2021, Italian shipbuilder Fincantieri announced at their press release that they and Ministry of Defense of Indonesia have signed a contract for the supply of six FREMM frigates, the modernization & sale of two Maestrale-class frigates, and other related logistical support. There may also be collaboration between Fincantieri and PT. PAL shipyard regarding local production on some of the FREMM frigates. The two Maestrale-class will be acquired and modernized by Fincantieri after the ships were retired from the Italian Navy.

On September 16, 2021, during Defense and Security Equipment International (DSEI) 2021 event in London, Babcock said it has secured the first export contract for its Arrowhead 140 (AH140) frigate, which is based on the hull of the Iver Huitfeldt-class frigate, through a design license agreement with PT.

As of 2024, both KRI Makassar (590) & KRI Surabaya (591) were observed to be fitted with one Leonardo OTO Twin 40L70 Compact with a stealth cupola on the bow of each vessels as main gun.

Minesweepers
The Indonesian Navy has allocated $215 million to replace its two Pulau Rengat-class minesweepers. In January 2019, Indonesia's Ministry of Defence (MoD) has signed a contract with Abeking & Rasmussen to design and construct two mine countermeasures vessels (MCMVs) for the Indonesian Navy. The 62 meters vessels will be an evolution of the German Navy's Frankenthal-class, and will replace the TNI-AL's ageing fleet of two Pulau Rengat-class MCMVs, both of which were commissioned in March 1988.

Abeking & Rasmussen on October 11, 2022, launch the lead vessel, KRI Pulau Fani (731) during ceremony in Lemwerder, Germany. The Pulau Fani-class MCMVs will each be equipped with two unmanned surface vehicles (USVs), and these will be carried on-deck in the vessel's aft section. The USVs both feature Abeking & Rasmussen's SWATH (Small Waterplane Area Twin Hull) design.

During IMDEX Asia 2023 in Singapore, Anschütz is showcasing a mine countermeasure (MCM) suite designed and developed for the Indonesian Navy upcoming Pulau Fani-class MCMVs.

These include SharpEye MK11 and MK7 radars, LTR 400 IFF transponder and Tactical Data Link, as well as sonar and unmanned underwater vehicles dedicated to mine hunting.

Hydrographic and oceanographic research vessel
On 15 September 2023, PT. Palindo Marine held first steel cutting ceremony for one BHO (Bantu Hidro-Oseanografi) 105m ship. The procurement of this ship is the result of a contract between Indonesia Ministry of Defense and Abeking & Rasmussen (A&R), in December 2022. In the implementation of the ship construction, Abeking & Rasmussen collaborated with PT. Palindo Marine in Batam as part of the transfer of technology (ToT) scheme for the construction of the research vessels and also as an effort to increase the usage of local content on the program. As the ship concept is based on a proven design by FASSMER, the project was handled jointly from the beginning. While A&R, as general contractor, is responsible for the customer’s requirements in terms of delivery, local value creation and transfer of technology, FASSMER is responsible for the design and construction of the vessel.

On 14 December 2023, PT. Palindo Marine on its facility in Batam in cooperation with German shipyards, Abeking & Rasmussen and FASSMER held keel-laying ceremony for BHO-105m vessel (yard number 6515), TNI AL’s future 105-metre ocean-going hydro-oceanographic auxiliary ship known as Bantu Hidro-Oseanografi (BHO) types of ship in Indonesian navy services. Abeking & Rasmussen stated that once the pre-outfitted hull is completed, the ship will be sent to Weser River in Germany for final outfitting. Previous reports suggest that this cooperation is part of the technology transfer originating from the purchase of two mine countermeasures vessels (MCMV), KRI Pulau Fani (731) and KRI Pulau Fanildo (732), for TNI AL. The ship will have a maximum top speed of 16 knots, accommodate 90 crew, and be equipped with various devices, including Autonomous Mine Detector (AUV), Conductivity, Temperature, Depth (CTD) Rosette, Light Detection and Ranging (LiDAR) Drone, Magnetometer, Multibeam Echo sounder, Remotely Operated Vehicle (ROV), Side Scan Sonar, and Seismic Towed Streamer, etc.

The vessel were also said to have some submarine rescue capability aside from her main role as the navy's hydro-oceanographic research vessel.

Submarine rescue vessel
On 12 September 2023, Submarine Manufacturing and Products Ltd (SMP), a UK based manufacturer and supplier of diving and subsea rescue equipment, they will provide its new Submarine Rescue System (SRS) to the Indonesian Navy. The SRS will be hosted on a mothership designed by independent design and engineering consultancy, Houlder and delivered by its Indonesian strategic partner, BTI Defence. The three-year build contract will include the SRS, centered around SMP’s new SRV-F Mk3 rescue submersible. The SRV-F Mk3 has been developed as a hybrid system which is capable of deployment both by air and on its mothership. When deployed by air, the rescue submersible can be towed to and from the distressed submarine’s location without needing to be recovered to deck, it can also dive to depths of 500m and able to carry up to 50 rescuees at a time.

The custom build of the mothership will take place in region, along with the associated expert training for the Indonesian Navy who will operate the system when it is in service. The mothership is fitted with a suite of support equipment, including a handling system, an advanced Transfer Under Pressure (TUP) system and a dedicated Decompression Chamber, enabling the immediate medical attention and treatment of rescued personnel.

The mothership includes an aft working deck arrangement and a large, dedicated operations room with an attached communications suite, which has a clear view over the working deck to support rescue operations. The design also incorporates multiple small boats for rescue duties and a helipad that takes the appropriate medium-to-large sized rescue helicopters. The ship will have a large permanent hyperbaric chamber and a dedicated 10 berth hospital. Permanent onboard accommodation for up to 90 people with over 30 spare berths available and separate accommodation for rescued personnel, with up to 50 berths. The vessel will feature a dedicated closed hangar with climate control for rescue equipment. This ensures the equipment is protected from the environment and remains in optimal condition. It can also be maintained more easily and ensures crew comfort is maximized whilst conducting rescue tasks, an important consideration for equatorial operations.

Submarines
In January 2020 the Indonesian Minister of Defence Prabowo Subianto during a bilateral meeting in France and met with his French counterpart Florence Parly said the Ministry is interested on French military equipments including 48 Rafale jet fighters, 4 Scorpène submarines, and 2 Gowind corvettes.

On 10 February 2022 the Indonesian Minister of Defence Prabowo Subianto and his French counterpart Florence Parly witness the signing of Memorandum of Understanding (MoU) between Kaharuddin Djenod, CEO of PT. PAL and Pierre Eric Pommellet, CEO of Naval Group on cooperation in research and development between PT. PAL and Naval Group regarding the plan to purchase two Scorpène submarines with AIP (Air-independent Propulsion) along with weapons and spare parts as well as training with local production of said submarine on PT. PAL facility in Surabaya, East Java.

On 2 November 2022 Naval Group and PT. PAL signed a Memorandum of Understanding to start the creation of an Indonesian Energy Research Lab to cooperate on energy and propulsions solutions in the naval field. This project consists of the creation of the Indonesian Energy Research Lab to develop, in Indonesia, the next generation of submarine energy solutions.

As of October 2024, French shipbuilder Naval Group has updated its Scorpène submarine proposal to Indonesia. Dubbed ‘Scorpène Evolved’, the submarine’s propulsion system will be installed with a full Lithium-ion Batteries (LiBs) configuration, thus giving it the longest endurance of any other variant in the Scorpène family.

On 26 February 2024, Representatives from French shipbuilder Naval Group begin contract negotiations for two lithium-ion batteries-equipped Scorpène Evolved diesel-electric submarines with Indonesian MoD in Jakarta. A major point of the discussions included how the program would be financed should a contract materialize. Under this arrangement, both submarines will be fully built in Surabaya, with construction work on the first boat scheduled to begin 14 months after the contract becomes effective and once funding sources and an initial payment are secured.

On 28 March 2024, Indonesia chose Naval Group and PT. PAL to strengthen the capabilities of the Indonesian Navy with two Scorpène Evolved full lithium-ion battery (LiB) submarines to be built fully in Indonesia's PT. PAL shipyard, through a transfer of technology from Naval Group. Key features of each Scorpène Evolved boats includes an overall length of 72 m and having surface displacement between 1,600 and 2,000 tons. Accommodation for a crew of 31 and will have 6 torpedo tubes and can take up 18 weapon payloads. The submarine will have maximum submerged speed exceeding 20 knots and can attain a maximum diving depth of over 300 m. The vessels also boast an autonomy exceeding 78 days on an 80-day mission and can remain submerged for more than 12 days. The adoption of full lithium-ion technology in the energy system allows for higher energy efficiency, reduced charging time, and increased tactical mobility regardless of the state of charge.
