Nagapasa-class submarine explained

The Nagapasa class is an upgraded variant of the, also known as Improved Chang Bogo. The vessels were built by the South Korean Daewoo Shipbuilding & Marine Engineering (DSME) and the Indonesian PT PAL. As of 2021, six ships have been planned, which were divided into two batches. Batch 1 consists of three ships and all are already commissioned. Batch 2 also consists of three ships that are in the early development stage.[1] The class is named for weapon of Indrajit, Nagapash .

Development

In December 2011, DSME won a contract to build three 1,400-ton s for Indonesia at a cost of $1.07 billion.[2] Construction of the submarines started in January 2012 for delivery by 2015 and 2016, and for commissioning in the first half of 2018. They are equipped with torpedoes and guided missiles.[3] [4] The submarines were described to be Korea's original model, bigger and more advanced than Indonesia's refurbished Type 209/1300.[5] Initially the offered submarines were going to be in-service Republic of Korea Navy submarines.[6] The sale will be done without the involvement of German companies.[7] South Korea was the only country outside Germany independently offering the Type 209 submarine for sale. Indonesia was also offered two license-built Type 209 submarines manufactured by a group of Turkish (SSM - Undersecretariat for Defense Industries) and German companies (HDW/ThyssenKrupp), a deal reported to be valued at $1 billion.[8] SSM was also offering the leases of Type 209 submarines until new submarines could be completed. The offer has since been superseded by the DSME submarine contract. In early 2012, the 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.[9] These submarines are equipped with Wartsila ELAC LOPAS Sonar and flank sonar arrays, Indra's Pegaso RESM system and Aries low-probability of intercept radar,[10] L3's MAPPS integrated platform management systems[11] and Safran's Sigma 40XP inertial navigation systems.[12]

In 2019, South Korea signed another contract worth US$1.02 billion to sell three 1,400-ton submarines to Indonesia[13] and would be supported through a loan agreement.[14] However, the Indonesian government was reconsidering the contract .[15]
