Indonesian Navy Alugoro submarine progressing towards Sea Acceptance Tests

The NDD is part of the Alugoro submarine 53 steps-long Sea Acceptance Test (SAT) program. The NDD stage was declared successful, the Alugoro submarine succeeded in diving to a depth of 250 meters. According to Satriyo Bintoro, PT PAL Head of the Submarine Division, the NDD stage is very important because « after the NDD stage was successfully implemented it can be concluded that 90% of the submarine construction process has been successful ».

SAT activities are carried out in the northern waters of Bali island, one of the Indonesian Navy training areas offering adequate sea depth. During the NDD test, the Alugoro submarine was escorted by KRI Raden Eddy Martadinata (331) guided-missile frigate.

After the Alugoro submarine completes various testing processes such as the Harbor Acceptance Test (HAT) and SAT, it is planned to be handed over to the country’s Ministry of Defense for use by the Indonesian Navy in December 2020.

The Alugoro is the third of the Nagapasa-class submarine (also known as the DSME 1400 design or Improved Chang Bogo-class) for the Indonesian Navy (TNI AL). The DSME 1400 project is an upgrade of the built-under-license Type 209/1200 with increased length (up to 61.2 m) and displacement (about 1,400 tons underwater). 

The first submarine for Indonesia, Nagapasa (403), was launched by the DSME shipyard in Okpo on December 3, 2013. The submarine arrived in Indonesia on August 28, 2017. The second boat Ardadedali (404) was launched at the DSME facility in Okpo in 2014, launched on October 24, 2016 and transferred to the TNI AL on April 25, 2018, arriving in Indonesia in June 2018.
