During the 1970s the Republic of Korea Navy decided to import Exocet anti-ship missiles to deter North Korean naval provocations. Considering the fact that the DPRK Navy was then and now mostly composed of numerous small to midsize ships, a cheap, small guided anti-ship missile was proposed. In 1978 the Korean Agency for Defense Development (ADD) started the development of the "Hae Ryong" anti-ship missile, and by 1987 the ROK Navy approved for the mass production of the missiles. But the "Hae Ryong" was fitted with a semi-active laser guidance system, limiting its tactical capability during bad weather. Additional pressure from the United States ultimately resulted in the termination of the project.
