Armament

The Jang Bogo-class submarine (Hangul: 장보고급 잠수함, Hanja: 張保皐級潛水艦) or KSS-I (Korean Submarine-I) 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 Jang Bogo class Type 209 was exported by Korea to Indonesia in 2012, amid heavy competition from Russian, French, and German-Turkish consortiums including from Germany's original Type 209.[3] The variant was considered for possible purchase by Thailand as well, as both newly built and second-hand options.[5] The class is named for ancient Korean maritime figure Jang Bogo.
