The Indonesian Navy (TNI-AL) has received its third Nagapasa-class diesel-electric attack submarine built by Indonesian state-owned shipbuilder PT PAL in cooperation with South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME).

The event took place at PT PAL's Surabaya shipyard on 17 March 2021. Among those who attended the ceremonies were Indonesian Defense Minister Prabowo Subianto, South Korean Defense Acquisition Program Administration (DAPA) head Kang Eun-Ho, Indonesian Armed Forces (TNI) Commander Air Chief Marshall Hadi Tjahjanto, TNI-AL Chief of Staff Admiral Yuno Margono, DSME Vice President Park Doo-Seon, and other officials of the TNI, TNI-AL, Indonesian Ministry of Defence (MOD), and government agencies.

The submarine, named the Alugoro (405), was an important milestone for the Indonesian shipbuilding industry as it was the first submarine built in Indonesia, and the first submarine built in Southeast Asia.

The first two ships of the class, the KRI Nagapasa (403) and the KRI Ardadedali (404) were built by DSME in South Korea, and were delivered in 2017 and 2018, respectively. 

As part of a US$1.02 billion contract between the Indonesian MOD and DSME, 2 submarines will be built by DSME, while PT PAL would be receiving technology transfer to allow the construction of the third Nagapasa-class submarine using sections built by DSME and PT PAL. 

The Nagapasa-class is based on DSME's DSME-1400 Improved Chang Bogo submarine design, which is a derivative of the German Type  209/1400 submarine design from Thyssen-Krupp Marine Systems (TKMS).
