Indonesian Navy takes delivery of 1st locally built submarine

South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) has handed over KRI Aluguro (405), a new 1,400-ton diesel-electric submarine, to the Indonesian Navy.

The delivery ceremony was held at the state-owned PT. PAL shipyard in Surabaya, Indonesia, on 17 March 2021, the navy and the shipbuilder said in separate statements.

Launched in 2019, the 61-meter-long unit is based on DSME’s first-built submarine, the Jangbogo.

KRI Aluguro is the third Nagapasa-class submarine assembled in Indonesia under a transfer of technology agreement with DSME worth $1 billion.

In 2019, DSME also signed a contract with Indonesia worth an estimated $1 billion to construct an additional three 1,400-ton submarines in the class.

The newbuild was built in pieces at DSME’s Okpo shipyard in Korea and assembled at PT PAL shipyard in Indonesia.

The Indonesian Navy’s first two Nagapasa-class boats — KRI Nagapasa (403) and KRI Ardadedali (404) were built at DSME’s shipyard in Okpo, Geoje, and delivered in August 2017, and April 2018.

The Nagapasa-class submarines are operated by a crew of 40 sailors. The Indonesian Navy vessels have an operating range of approximately 10,000 nautical miles and can reach a speed of 21 knots while submerged.
