The South Korean news agency Yonhap reported Daewoo Shipbuilding & Marine Engineering Co.(DSME) said Wednesday it has successfully delivered a submarine to Indonesian Navy. The submarine, named KRI ALUGORO, was built in pieces at Okpo shipyard of Daewoo Shipbuilding in Geoje Island, about 400 km south of Seoul, and assembled at PT PAL shipyard in Surabaya, Indonesia. The 61-meter-long Nagapasa-class submarine s, also known as Improved Chang Bogowas based on Daewoo Shipbuilding’s first-built submarine, the Jangbogo. The 1,400-ton submarine was the third of three submarines that Daewoo Shipbuilding won in a deal worth US$1.1 billion in 2011.
In early 2012, the South Korean defense firm LIG Nex1 exhibited its latest suite of indigenously developed submarine sensors, submarine combat systems, and heavy-weight torpedoes and wire-guided torpedoes in Indonesia for potential use by the Indonesian Navy’s submarine forces. These diesel submarines will be equipped with Atlas Elektronik CSU 90 hull-mounted passive and active search-and-attack sonar and flank sonar arrays, Indra’s Pegaso RESM system and Aries low-probability of intercept radar, L3’s MAPPS integrated platform management systems and Safran’s Sigma 40XP inertial navigation systems.
KRI Nagapasa was commissioned by Indonesian Minister of Defense Ryamizard Ryacudu in South Korea on 2 August 2017. Afterwards, the submarine sailed to Surabaya, where she was received by Chief of Staff of the Navy Ade Supandi on 28 August 2017. Her name is based on the Nagapasha, a mythical weapon in the Ramayana. KRI Nagapasa was then assigned to the Indonesian Navy Eastern Command (Koarmatim). KRI Ardadedali was delivered and commissioned in a ceremony at DSME’s shipyard in Okpo, Geoje on 25 April 2018, before sailing to its base in Surabaya. She was attached to the Indonesian Navy’s 2nd Fleet Command, based in Surabaya. Her name Ardadedali was based on an arrow in possession of Arjuna in the Mahabharata epic.
