C-Star

The C-Star (SSM-700K), is a sea-skimming surface-to-surface anti-ship missile designed by the South Korean Agency for Defense Development. The RoKN is already deploying the missile aboard Ulsan-class frigates under the designation Haeseong. Being designed and domestically produced, it avoids further dependence on foreign-made anti-ship weapons such as the U.S. Harpoon and French Exocet. Over the next few years all frigates and destroyers will have transitioned to the C-Star missile system.

A long-range cruise missile, it was developed for over-the-horizon warfare, capable of attacking targets out to 150 km (93 miles). Traveling at ultra-low sea-skimming altitudes, it uses a high- subsonic, high-capacity turbojet. The range is intended to give the warships the ability to reach distant targets without fear of retaliation.

The South Korean missile is generally considered a superior next-generation missile compared to the Harpoon and Exocet systems. It uses an Inertial Navigation System (INC) and Global Positioning System (GPS) to guide it toward its target, using a radio altimeter to maintain altitude. An active radar is used for targeting in the terminal phase immediately before impact. It was designed to be deployed in an active electronic warfare environment, fitted with both detection and countermeasures systems.

The warhead itself is similar to the Harpoon, fitted with an impact or penetration fuse. The C-Star is also suitable for shore-launched coastal defense from both fixed and mobile land platforms. The development agency claims "a 100 percent accuracy rate in live fire tests" including participation in RIMPAC multinational exercises.

It is reported that an unknown number of C-Star missiles were sold to Colombia.
