# Indonesian Navy

The Indonesian Navy (Indonesian: Tentara Nasional Indonesia Angkatan Laut, lit. 'Indonesian National Military-Naval Force', TNI-AL) is the naval branch of the Indonesian National Armed Forces. It was founded on 10 September 1945 and has a role to patrol Indonesia's lengthy coastline, to enforce and patrol the territorial waters and Exclusive Economic Zone (EEZ) of Indonesia, to protect Indonesia's maritime strategic interests, to protect the islands surrounding Indonesia, and to defend against seaborne threats.
The Navy is headed by the Chief of Staff of the Navy (Kepala Staf Angkatan Laut – KSAL or KASAL). The Indonesian Navy consists of three major fleets known as "Armada", which are Komando Armada I (1st Fleet Command) located in Tanjung Uban, Komando Armada II (2nd Fleet Command) located in Surabaya, Komando Armada III (3rd Fleet Command) located in Sorong, and one Komando Lintas Laut Militer (Military Sealift Command). The Navy also heads the Marine Corps.

## Mission

According to Article 9 of Law No.34/2004 on the National Armed Forces, the Navy has the following tasks:
* perform military duties in national defence;
* enforce the law and secure order in the sea area of national jurisdiction in accordance with national laws and ratified international laws;
* perform diplomatic duties in support of foreign policy set by the government;
* engage in other duties relevant to the maintenance and development of naval power;
* support civilian empowerment in sea defence areas.

## History
### Creation and actions during the revolution

The official Indonesian Navy's history began on 10 September 1945, at the outset of the Indonesian National Revolution. The administration of the early Indonesian government established the People's Marine Security Agency (Badan Keamanan Rakyat Laut/BKR Laut) on 22 August 1945, the predecessor to the modern Indonesian Navy. BKR Laut with only wooden ships, a few landing craft, and weapons left by Japan, was initially composed of Indonesian sailors who had served in the ranks of the Royal Netherlands Navy during the Dutch colonial period, and who had fought the Japanese during the years of military occupation, plus active militias who served with the Japanese and ex-Indonesian officers and ratings of the Imperial Japanese Navy. The formation of the Indonesian military organization known as the People's Security Army (Tentara Keamanan Rakyat/TKR) on 5 October 1945, at the height of the National Revolution, helped spur the further existence of the TKR Naval Branch – the Peoples' Security Navy (TLKR), which later became the Republic of Indonesia Navy (Angkatan Laut Republik Indonesia / ALRI). The name ALRI was used until 1970, when it was changed to Tentara Nasional Indonesia Angkatan Laut (TNI-AL).
As the revolution grew, and the Navy began its work, naval bases were established throughout the archipelago. Former ships of the Imperial Japanese Navy handed down to the new republic were acquired. Simple strength did not discourage the Navy from deploying Sea Traffic Operations in order to spread the news of the proclamation and help to form and train Republican military forces and militias nationwide. Besides, they also attempted to breach the Dutch naval blockade in order to obtain aid from abroad.
The newly formed navy confronted the more superior Royal Netherlands Navy in Bali, Sibolga, and Cirebon. Cross-sea operations are also able to prepare the armed forces in South Kalimantan, Bali, and Sulawesi. Limitations in strength and ability to lead the Navy had to divert the struggle in the countryside after most boats were sunk and nearly all bases battered by the Dutch and Allied military forces. But the determination to participate again in the sea never subsided. In the hard times during the National Revolution, the Navy succeeded in forming the Fleet Forces (CA), Marine Corps (Corps Mariniers/ CM), and educational institutions in various places. The formation of these elements marks the presence of aspects for the formation of a modern national navy.

### After the revolution

The end of the War of Independence marked the development of the Navy as a modern naval power. In accordance to the results of the Round Table Conference, in 1949, the Navy received a variety of war equipment such as warships and its supporting facilities such as naval bases. This step came along with the process of consolidation within the Navy, revamping the organization and recruitment of personnel through educational institutions before manning naval equipment. During 1949–1959, the Indonesian Navy managed to enhance its strength and improve its capabilities. In the field of organization the navy reorganized its Fleet Forces, the Marine Corps – then Korps Komando Angkatan Laut (KKO-AL – Naval Commando Corps Command), naval aviation and a number of regions as territorial defense command aspects of the sea. Naval combat equipment grew, both from former Dutch equipment handed down to the new republic and through purchase from other countries.
With the increased strength and the capability, the Navy began refining the strategy, tactics, and techniques of marine operations, which are directly applied in a variety of military operations in order to deal with separatist movements that have sprung up in the year from 1950 to 1959. In operations against PRRI in Sumatra, Permesta, Darul Islam in West Java, and RMS in the Moluccas, the Navy gained lessons in applying the concept of marine operations, amphibious operations, and joint operations with other forces.

### At the height of the Cold War

At the time the country started to recover from the threat of disintegration, in 1959, the Navy launched a program known as Menuju Angkatan Laut yang Jaya (rough translation – "Towards A Distinguished Navy"). The Navy experienced a significant progress until 1965 which was motivated by the politics of confrontation in order to seize West Irian, which Indonesia claimed as part of its territory, a claim refuted by the Dutch government. As part of the increasing military ties between Indonesia and the Warsaw Pact, various naval combat equipments from Eastern European countries strengthened the Navy and become the dominant force at the time. Some military equipment of Soviet production served in the ranks of the Navy, among others Sverdlov-class cruiser, Skoryy-class destroyer, Riga-class frigate, Whiskey-class submarine (the first such vessels to be used in Southeast Asia), Komar-class missile boat, Ilyushin Il-28 long-range bomber aircraft of Naval Aviation and the PT-76 Amphibious light tanks, BTR-50 APCs and BM-14 MRLs (Southeast Asia's first ever MRL system in service) of the Commando Corps, the first of their kind in the region. With such power in the era of the 1960s the Navy was called the largest Navy in Southeast Asia and one of the strongest within the Asia-Pacific, outranking those of its neighbors in armament and prestige.
By January 1962 the Indonesian Navy started preparing several naval operations for the liberation of West Irian known as Operation Trikora, which began on 15 December the year before as part of the military component of that operation under the Mandala Command for the Liberation of West Irian (Komando Mandala Pembebasan Irian Barat) . Beginning 1 January, fast-ship torpedo vessels of the Navy were forward deployed to deal with destroyers, frigates and aircraft of the Royal Netherlands Navy. On January 15, 1962, Commodore Yos Sudarso along with RI Matjan Tutul sank in the sea battle in the Arafura Sea. This battle is known as the Vlakke Hoek incident. By mid-year the Navy was preparing to organize its role in the planned Operation Jayawijaya which would have been the largest amphibious operation in the history of Indonesian military operations if commenced. The naval component was made up of 100 warships and 16,000 sailors and Marines. The deployment of forces preparatory to the planned landings in West Papua forced the Dutch to return to negotiations and reached an agreement to hand over West Irian to Indonesia.
After seizing West Irian, Sukarno by 1963 moved his sights on Malaysia. Indonesia political confrontation against Neocolonialism and Imperialism (Nekolim) continued in Operation Dwikora to oppose the formation of Malaysia. Although elements of the National Armed Forces were prepared for operational deployments to the new state, the operations were limited to the infiltration operation along the Borneo frontier. Soldiers from the marine corps were involved in the operations which targeted both the Malaysian states of Sabah and Sarawak. The Marine Corps, though, would figure in the 1964 MacDonald House bombing in Singapore.

### 1965 onwards

Operation Dwikora was discontinued in 1965 along with a succession of governments in Indonesia after an abortive coup d'état took place in Jakarta, which were organized by the self-proclaimed organization of Indonesian National Armed Forces members who, in the early hours of 1 October 1965, assassinated six Indonesian Army generals and killed 3 more. Since 1966, the Navy experienced a new chapter in its history as the military integration efforts. With the integration of the armed forces organizationally and operationally been able to keep up on the implementation of tasks in the field of defense and security so doctrinally, the direction of development of the power and capabilities of each branch to be concentrated. The operations were prominent during the period of the 1970s was Operation Seroja in the framework of the integration of East Timor to Indonesia. The Navy played an active role in the operation of landings, a joint ground operation, and transporting troops by sea.
Starting the 1980s the Navy began to modernize combat equipment. Ships made in Eastern Europe that has been the core strength of the Navy in the era of the 1960s and 1970s were not suited to meet the growing and changing needs for the navy and its branches (saving for its submarines and several corvettes and frigates, the submarines were retired in 1990). The worsening relations between Indonesia and the Soviet Union after the overthrow of President Sukarno resulted a cessation of military cooperation between the two countries and the Warsaw Pact. Therefore, the Navy switched once more to using Western technology to modernize the power and ability to buy warships, logistics vessels and other major combat equipment from various countries. Included among those commissioned during the Suharto presidency were Fatahillah-class corvette and Ahmad Yani-class frigate from the Netherlands, Cakra-class submarine from West Germany, fast patrol boat from South Korea, and the GAF Nomad patrol aircraft from Australia. In 1993 the Navy also received 39 ships from the former Volksmarine (East German Navy), including 16 Parchim-class corvettes, 14 Frosch-class landing ship tanks (LSTs), and 9 Kondor II-class minessweepers. Aside from these the Navy reorganized its forces. In 1984, as part of an-Armed Forces wide unit reorganization, the former Naval Regions, which in turn governed Naval Bases and Naval Districts and subordinate Naval Stations and Naval Air Stations, were turned into Main Naval Bases of the Navy Fleet Commands, divided from the formerly unified National Fleet Command on the basis of the Western and Eastern Squadrons of the Fleet. The National Fleet Command by the late 1960s was briefly split into two operational fleets – the Ocean Fleet Force (for defense operations abroad) and the Archipelago Fleet (for local defense operations within Indonesia), until these were fused into a unified command in 1970.
At the same time the Navy began to develop a non-combat military operations in the form of humanitarian service program Surya Bhaskara Jaya in various remote areas in Indonesia that can only be reached by sea. The core of the operating activities are health services, construction and rehabilitation of public facilities and various counseling in health, law, and civil defense. This event is held regularly every year until now. A number of countries also participated in these activities, among others, Singapore, Australia and the United States. The navy also seeks promoting the development of the maritime sector, especially those related to aspects of defense and security at sea, activities that had been present since independence before the formation of the Ministry of Maritime Affairs and Fisheries. The actual activities undertaken today by the Navy are establishing marine development assessment bodies together with the government and private sectors in some areas, coastal village pilot programs are summarized in Coastal Rural Development (Bindesir), and the National Potential Development Program for Maritime Defense (Binpotnaskuatmar). In order to encourage the spirit of the seafaring nation, the Navy held an international scale maritime event Arung Samudera 1995. The navy was responsible for the programs for National Maritime Year 1996 and the Bunaken Declaration of 1998, which is a manifestation of marine development in Indonesia.

### Expansion in the 21st century

During the presidencies of Susilo Bambang Yudhoyono and Joko Widodo, the Navy has begun a program of expansion of its combat commands and has begun a program of national warship construction in naval arsenals, while acquiring nationally produced transport aircraft for the needs of the Navy.
On December 17, 2024, Indonesian Navy Chief of Staff Admiral Muhammad Ali inaugurated two Fast Patrol Warships (PC 60), KRI Hampala-880 and KRI Lumba-Lumba-881, at a ceremony held at Sunda Kelapa Pier, North Jakarta. The ships were produced by domestic shipbuilder PT. Caputra Mitra Sejati.

## Integrated Maritime Surveillance Systems

With various coastal radars, Indonesia has one of the world's longest Integrated Maritime Surveillance Systems (IMSS). The network covers more than 1,205 kilometres (749 mi) of coastline in the Straits of Malacca and about 1,285 kilometres (798 mi) of coastline in the Sulawesi Sea.
The IMSS is a tightly integrated network of ship and shore based sensors, communications devices, and computing resources that collect, transmit, analyze and display a broad array of maritime data including Automatic Identification System (AIS), surface radar, surveillance cameras, Global Positioning System (GPS), equipment health monitors and radio transmissions of maritime traffic in wide operating areas. Redundant sensors and multiple communication paths make the IMSS a robust and capable system. The IMSS enhances Indonesia's ability to detect, track, and monitor vessels passing through territorial and international waters. This capability is crucial to combating piracy, illegal fishing, smuggling, and terrorism within and around Indonesia's maritime borders. The IMSS is operated by the Indonesian Navy, and consists of 18 Coastal Surveillance Stations (CSS), 11 Ship-based Radars, two Regional Command Centers, and two Fleet Command Centers (Jakarta and Surabaya).

## Rank structure

In the Navy, as well as in other armed forces branches in Indonesia, the rank consists of officer in Indonesian known as "Perwira", NCO "Bintara" and enlisted "Tamtama".
The Indonesian Navy is one of few navies in the world which use rank titles similar to its Army, except for flag officers and lower-ranking enlisted sailors. However the Indonesian Marine Corps, which is a branch of the Navy, uses exactly the same rank titles as those of the Army, but still uses Navy-style insignia (for lower-ranking enlisted marines, blue replaces the red colour). Starting 2006, navy personnel assigned abroad are authorized to use foreign service uniform, officially named "Black Navy" (similar to service dress blues in United States Navy) during their service overseas (e.g. during training exercises), which includes sleeve and cuff insignia.
The proper title to address rank are as follows, all high-ranking officers (Admiral or Marine General) use their rank followed by "(TNI)", while other officers use their rank followed by respective branch/corps. For example, a Navy captain from fleet forces corps uses the title "Kolonel Laut Pelaut" (written as "Kolonel Laut (P)"), while a Navy Vice Admiral uses the title "Laksamana Madya (TNI)" regardless of their previous branches. Warrant officers, NCOs and enlisted seamen may put their respective branch/corps specialty, for example: "Pembantu Letnan Dua SAA" (warrant officer from surface weaponry corps) and "Kelasi Dua TRB" (seaman recruit from torpedo corps). All marine corps personnel, general officers inclusive, use their rank followed by "(Mar)".
Note: Indonesia is not a member of NATO, so there is not an official equivalence between the Indonesian military ranks and those defined by NATO. The displayed parallel is approximate and for illustration purposes only.
Note: The red banding on the rank insignia denotes the personnel holding a command position which is agnostic of rank.
