TNI–AL submarines

After 13 years of negotiations, delays and finally construction Indonesia has launched the first of three South Korean Chang Bogo class submarines in late March. This boat will enter service in 2017 followed by the second in 2018. The third boat is to be built in Indonesia with South Korean help. Chang Bogo is an improved version of the German Type 209, but built in South Korea under license. The South Korean Navy put nine locally built Chang Bogos into service between 1993 and 2001. It is a proven design and that was a major selling point.

The Chang Bogos are 1,200 ton boats that are 55.9 meters (174 feet) long, have a top speed while submerged of 39 kilometers an hour, and a top surface speed of 20 kilometers an hour. Range is 20,900 kilometers at a surface speed of 7.4 kilometers an hour. Endurance is 50 days and the highly automated boat has a crew of only 31. Armament is 14 torpedoes fired from eight 533mm (21 inch) tubes.

DSME launches first Indonesian Type 209/1400 SSK | IHS Jane's 360 - 24 March 2016

South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) has launched the first of three Type 209/1400 diesel-electric submarines (SSK) on order for the Indonesian Navy (Tentara Nasional Indonesia - Angkatan Laut, or TNI-AL).

The boat was launched on 24 March at DSME's Okpo shipyard in a ceremony attended by Indonesian defence minister Ryamizard Ryacudu and TNI-AL chief Admiral Ade Supandi. TNI-AL sources have confirmed to IHS Jane's that the submarine has been given the pennant number 403.

The vessel is part of a KRW1.3 trillion (USD1.1 billion) contract signed between DSME and the Indonesian Defence Ministry in December 2011. Under the contract the first and second vessels are to be built in South Korea, while the third boat will be produced at Indonesian state-owned shipbuilder PT PAL's premises in Surabaya in a technology transfer arrangement.

According to specifications provided by DSME the Indonesian Type 209, which displaces 1,400 tonnes dived, has a top speed of 21 kt and a maximum operating range of approximately 10,000 n miles at 10 kt while surfaced. The submarine has been designed for a range of missions, including anti-surface warfare (ASuW), anti-submarine warfare (ASW), mine laying, and special forces operations, said DSME in a statement on the launch.

Indonesia moves forward with talks for three more Type 209 submarines | Janes - 11 January 2019

Key Points
* Indonesia is edging closer towards acquiring three more diesel-electric submarines from South Korea
* The country has been studying several vessel types for the requirement, but considerations of commonality and maintenance costs have led to the current frontrunner

Should it materialise, the contract, which includes a support and training package across all three submarines, is expected to be worth approximately USD1.2 billion.

Indonesia signed a USD1.1 billion deal for three Type 209/1400 submarines with DSME in December 2011. Two boats under the contract have been delivered, while a third vessel is currently awaiting launch at PT PAL's premises in Surabaya. The first submarine was commissioned in August 2017 as KRI Nagapasa (403).

However, there are several decisions yet to be made, and these mainly pertain to workshare arrangements that can be undertaken for each vessel, the sources confirmed.

Once it materialises, the contract, which includes a support and training package across all three submarines, is expected to be worth about USD1.2 billion.

Jakarta signed a USD1.1 billion deal for three Type 209/1400 submarines with DSME in December 2011. Two submarines under this contract have been delivered, while a third is awaiting launch at PT PAL's premises in Surabaya. The first submarine was commissioned in August 2017 as KRI Nagapasa (403).

Indonesia moves third Nagapasa submarine to alternative site for long-delayed launch
28 March 2019

The vessel was transferred to its launch site at PT PAL's dock at Semarang via a 300-foot intermediate barge, and is now slated for launch on 12 April if all precedents for the ceremony are assessed to be in order, an industry source confirmed with Jane's on 28 March.

Alugoro was originally slated for launch at PT PAL's dock adjacent to Jalan Letnan Supriadi as early as October 2018. However, PT PAL engineers later discovered that the location has become too shallow owing to sedimentary deposits. The situation was aggravated in recent years by construction work at the nearby Terminal Teluk Lamong, said an industry source who first informed Jane's of the situation.

The submarine will now be launched at the same site where larger ships, such as the Philippine Navy's strategic sealift vessels (SSVs), first took to the water.

Alugoro is Indonesia's third-in-series overall for the Nagapasa class. But the boat is the first-ever submarine to be assembled locally at PT PAL's facilities in Surabaya. The SSK's assembly was done in collaboration with engineers from South Korea's Daewoo Shipbuilding and Marine Engineering (DSME) as part of a technology transfer programme.

Indonesia launches first locally assembled submarine

Indonesian shipbuilder PT PAL has launched the country's third Nagapasa (Type 209/1400)-class diesel-electric submarine (SSK).

The vessel, which will be in service as KRI Alugoro (405) once commissioned, was launched on 11 April at PT PAL's Semarang Dock in Surabaya Indonesia.

While third-in-class overall, Alugoro is the first-ever submarine to be assembled in Indonesia. Its assembly was done in collaboration with engineers from South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) as part of a technology transfer programme.

The submarine was subsequently transferred to the company's Semarang Dock, located about 750 m away, via a 300-foot intermediary barge in March 2019. This is the same location where PT PAL has launched larger naval ships, such as the Philippine Navy's strategic sealift vessels (SSVs).

Alugoro is part of a KRW1.3 trillion (USD1.2 billion) contract signed between DSME and the Indonesian Ministry of Defence in December 2011 for three SSKs. The vessel derives its design from the Republic of Korea Navy's (RoKN's) Chang Bogo-class boats.

DSME to deliver three more submarines to Indonesia

Daewoo Shipbuilding & Marine Engineering (DSME) signed a contract on 12 April with representatives from the South Korean and Indonesian governments to deliver a second tranche of three Type 209/1400 diesel-electric submarines to the Indonesian Navy (TNI-AL).

< snipped >

The contract was signed in Indonesia one day after Indonesian shipbuilder PT PAL launched the TNI-AL’s third Type 209/1400 submarine, which was acquired through a USD1.1 billion contract awarded to DSME in December 2011.

Under this initial tranche, the first two boats were delivered to the TNI-AL in 2017 and 2018 and PT PAL is constructing the third in Indonesia under licence from the South Korean shipbuilder. The third boat is scheduled to be commissioned later this year.

A similarly collaborative programme is expected to support the construction of the second-tranche submarines.

Indonesia signs USD1 billion contract for three follow-on SSKs to Nagapasa class | Janes - 12 April 2019

The Indonesian Ministry of Defence has signed a USD1 billion contract with South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) for three Type 209/1400 diesel-electric submarines (SSKs). The contract was signed on 12 March in Bandung, West Java.

The vessels will be a follow-on to the country’s Nagapasa class, the contract for which was also awarded to DSME in 2011. Two submarines under this earlier contract have been commissioned by the Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut: TNI-AL), while a third was launched at PT PAL’s premises in Surabaya on 11 March.

For the first vessel under the new contract, which will be the fourth-in-class overall, two of the SSK’s six modules will be constructed by PT PAL in Surabaya, while DSME will build the remaining four in South Korea. The Indonesian-built modules will be shipped to Okpo for assembly.

For the second submarine, which will be the fifth-in-class overall, PT PAL will construct four of the six modules in Surabaya, with DSME constructing the remaining two in Okpo. As with the first vessel, modules that have been constructed in Surabaya by PT PAL will be shipped to South Korea for final assembly.

For the third vessel in the contract, which will be the sixth-in-class overall, PT PAL initially proposed to build the entire submarine.
