Chang Bogo-class Submarine

The Chang Bogo-class submarine (Hangul: 장보고급 잠수함, Hanja: 張保皐級潛水艦) is a variant of the Type 209 diesel-electric attack submarine initially developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, intended for service with the South Korean Navy and Indonesian Navy. A Daewoo (DSME)-upgraded model of the Type 209, the Chang Bogo-class is being independently exported by Korea to Indonesia in 2012, after a series of heavy competitions from Russian, French, and German-Turkish consortiums including from Germany's original Type 209. The variant is being considered for possible purchase by Thailand as well, as both newly built and second-hand options. The class is named for Korean maritime figure Jang Bogo.
