The Republic of Korea Navy (RoKN) took delivery of its sixth Son Won Il-class (Type 214) diesel-electric air-independent propulsion (AIP) attack submarine on July 10, Yonhap news agency reported citing Defense Acquisition Program Administration.
The 1,800-tonne vessel, to be named RoKS Yu Gwan-sun (078), was handed over by South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) at its shipyard in Geoje Island near Busan. Yu Gwan-sun was launched in May 2015 and is expected to be commissioned by the end of the year.
The Son Won Il-class (also known as KSS II–class) is a variant of the German Type 214 submarine build by Howaldtswerke-Deutsche Werft (HDW). South Korea ordered its first three KSS-II/ Type 214 boats in 2000. They are license-built in South Korea by country’s shipbuilding majors, Hyundai Heavy Industries and Daewoo Shipbuilding & Marine Engineering.
They are powered by two MTU Friedrichshafen diesel engines and fitted with Siemens polymer electrolytic membrane fuel cell AIP system. The submarines have a top speed of 20 kt submerged and 12 kt surfaced.
The vessels can be armed with long-range submarine-to-ground cruise missiles, anti-ship cruise missiles, heavyweight anti-ship torpedoes, and naval mines.
The submarines are equipped with Thales SPHINX-D Radar System and uses an additional pulse transmitter in the top of the mast.
Type 214 class submarines are also operated by Hellenic Navy (Greece) and Portuguese Navy. Turkey has also ordered the type for its Navy which are under construction at Gölcük Naval Shipyard.
