[THE INVESTOR] Daewoo Shipbuilding & Marine Engineering launched a 1,400-ton diesel submarine on Oct. 24 for the Indonesian Navy, a company official said. 

The submarine is the second of the three submarines being built under a 2011 deal worth US$1.1 billion. In March, the shipbuilder had a launching ceremony for the first submarine, said Yoon Yo-han, a spokesman for DSME.

The South Korean major ship builder held a ceremony for the second submarine at its shipyard in Geoje Island, close to the country’s southeastern port city of Busan, he said.

About 60 people participated in the ceremony, including company and Indonesian officials.

The shipbuilder is set to deliver the first and second submarines to Indonesia in March and October next year, respectively. The third submarine is scheduled to be delivered to the Southeast Asian country in 2018, Yoon said.

The submarines, a modified version of the Chang Bogo class currently in service in the South Korean Navy, can travel 18,520 kilometers without a port call, twice the distance from Busan to Los Angeles.

Chang Bogo class

In December 2011, DSME won a contract to build three 1,400-ton Chang Bogo-class submarines for Indonesia at a cost of $1.07 billion. Construction of the submarines will start in January 2012 for delivery by 2015 and 2016, for commissioning in the first half of 2018. They'll be equipped with torpedoes and guided missiles.The submarines are described to be Korea's original model, bigger and more advanced than Indonesia's refurbished Type 209/1300. Initially the offered submarines were going to be in-service ROKN submarines. The sale will be done without the involvement of German companies. South Korea is currently the only country outside Germany independently offering the Type 209 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. 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 The offer has since been superseded by the DSME submarine contract.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.

Improved Chang Bogo class
DSME signed a contract with Indonesia on for the supply of three Improved Chang Bogo-class submarines. These submarines will be equipped with Atlas Electronic 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, L-3's MAPPS integrated platform management systems and Sagem's Sigma 40XP inertial navigation systems.
