Hyundai Heavy Industries (HHI) has launched South Korea’s seventh class-214 KSS-II submarine, Hong Beom-do, at its Special and Naval Shipbuilding Division in Ulsan, South Korea.
The submarine has been named after the commander-in-chief of the Korean Independence Army, Hong Beom-do, and is expected to strengthen the nation’s capability to undertake underwater surveillance operations, according to a report by janes.com.
The diesel-electric air independent propulsion (AIP) submarine measures 65m-long and is 7m-wide, with a displacement capacity of 1,800t.
Powered by two MTU diesel engines, the submarine is capable of cruising at a maximum speed of 20k with a crew of 40.
The high-yield steel used to build the vessel is designed to enable it to dive up to 400m, and it can operate underwater for two weeks with Siemens polymer electrolytic membrane fuel cells.
The submarine is equipped with long-range submarine-to-ground cruise missiles, developed using Korea’s own technology; torpedoes and mines featuring an automatic simultaneous target tracking system; and a torpedo guidance and detection system.
