From Yonhap:

South Korea on Thursday launched its fifth 4,000-ton-class destroyer with a radar-evading “stealth” function here amid a fanfare of trumpets and fireworks as sailors celebrated the new addition to their fleet.

The 4,200-ton ship, equipped with a range of sophisticated weapons systems, was set afloat in a shipyard on the country’s second-largest island, about 406 kilometers south of Seoul.

The new destroyer, which has camouflage and stealth coatings on its surface, is equipped with SM-II ship-to-air missiles, Harpoon
anti-ship missiles, RAM-guided supersonic missiles and other naval guns as well as two anti-submarine Super Lynx helicopters, according to Navy officials. It can sail at a maximum speed of 30 knots per hour.

Cool boat, but what would Korea use it for? To sneak up on Japanese fishermen?
