Gwanggaeto the Great class destroyers
The Gwanggaeto the Great class destroyers, often called KD-I class, are destroyers, but are classified by some as frigates, operated by the Republic of Korea Navy. It was the first phase of ROKN's KDX program, in moving the ROK Navy from a coastal defence force to a blue-water navy.

The primary weapon deployed by Gwanggaeto the Great class vessels is the Super Lynx helicopter, which acts in concert with shipboard sensors to seek out and destroy submarines at long distances from the ships. The Gwanggaeto-class also carries a close-in anti-submarine weapon in the form of the Mark 46 torpedoes, launched from triple torpedo tubes in launcher compartments either side of the forward end of the helicopter hangar. A secondary anti-shipping role is supported by the RGM-84 Harpoon surface-to-surface missile, mounted in two quadruple launch tubes at the main deck level between the funnel and the helicopter hangar. For anti-aircraft self-defense the Gwanggaeto-class carries 16 RIM-7P Sea Sparrow. The Gwanggaeto-class also carries two 30mm Goalkeeper to provide a shipboard point-defense against incoming anti-ship missiles and aircraft. The main gun on the forecastle is an OTO Melara 127 gun.

The Gwanggaeto the Great class is powered by two General Electric LM2500-30 gas turbines and two Sangyong 20V 956 TB 82 diesel engines. The Gwanggaeto-class can reach a maximum speed of 30 knots.
