History
Specifications
The Batch I ships displace roughly 7,650 tons standard / 10,000 tons full load, with a length of 166 m, beam of 21.4 m, and draft of 6.25 m. Propulsion is four General Electric LM2500 gas turbines in a COGAG arrangement driving two shafts, giving a speed over 30 knots and a range of about 5,500 nautical miles. Armament includes a 127 mm Mk 45 Mod 4 gun, a 30 mm Goalkeeper CIWS, a RAM Block 1 launcher, 16 SSM-700K Haeseong anti-ship missiles, triple torpedo tubes for K745 Blue Shark torpedoes, and a 128-cell combination of Mk 41 VLS and K-VLS carrying SM-2 missiles, K-ASROC Red Shark rockets, and Hyunmoo III land-attack cruise missiles.
Service history
Sejong the Great was launched on 25 May 2007 by Hyundai Heavy Industries and commissioned on 22 December 2008. She has participated in multinational exercises including RIMPAC 2010 off Hawaii and various trilateral exercises with Japanese and U.S. Navy units in the Sea of Japan, and her Aegis radar demonstrated the ability to track a North Korean missile launch in April 2009.
Notable facts
With a missile capacity of 128 VLS cells, the class carries more missiles than the U.S. Arleigh Burke class or the Japanese Atago class, leading some analysts to argue the ships are better classified as cruisers than destroyers. The class remains in production, with later Batch II units (Jeongjo the Great and successors) featuring an enlarged hull, Aegis Baseline 9, and BMD capability.
