Security,
The South Korean government on April 30, 2019 approved plans to acquire new destroyers and submarines for the country’s fast-growing navy.
The $6-billion acquisition includes three Aegis destroyers armed with ballistic-missile interceptors and three submarines equipped with their own launchers for land-attack missiles.
The new ships could help Seoul’s navy to expand beyond its current, largely coastal mission. The main threat to South Korea is North Korea, specifically the North’s huge force of artillery that in wartime quickly could demolish Seoul and endanger millions of people.
But looking beyond the North Korean threat, South Korea clearly has ambitions to develop a far-sailing “blue-water” navy. There has been unofficial talk of the South Korea fleet embarking F-35 stealth fighters aboard its amphibious assault ships, in essence transforming the vessels into light aircraft carriers.
The South Korean navy in 2019 operates 68 major warships including 16 submarines, 12 destroyers, 13 frigates, 13 corvettes and 14 amphibious warfare ships. The fleet also includes scores of patrol boats, mine-warfare vessels and auxiliaries.
The three new Sejong the Great-class destroyers and three new Dosan An Chang-Ho-class submarines apparently will expand the fleet rather than replace older vessels.
“The new Aegis destroyers will be outfitted with an upgraded missile launch system which will allow them to intercept ballistic missiles,” Yonhap news agency reported. “They will also represent a marked upgrade in detection and tracking abilities.”
The navy currently possesses three of the Sejong the Great-class destroyers that it acquired between 2008 and 2012. The 11,000-ton-displacement destroyers are among the most heavily-armed in the world and boast 128 vertical missile cells for SM-3 air-defense missiles and Hyunmoo-3C cruise missiles.
At present the American-made SM-3 is most effective as a terminal- or boost-phase missile-interceptor, meaning it possess the speed, range and altitude performance to hit enemy ballistic missiles when they’re first launching or in their final seconds of flight.
