South Korea wants to buy another 58 Harpoon missiles from the United States. Such purchases will be drying up in the future, as South Korea has just introduced its own version of the Harpoon, the Haeseong. The South Koreans will be using the Haeseong in new warships it is building, instead of Harpoons. Originally, these new warships were designed to mount Harpoons, but the Haeseong is similar enough, in size and capabilities, that switching will not be a major problem. It appears that the Haeseong will eventually replace Harpoon in South Korean submarines and aircraft as well.
