South Korea has developed a cruise missile capable of striking most strategic targets in North Korea’s rear areas.

According to a military source, the state-run Agency for Defense Development developed the missile dubbed “Cheonryong." It has a range of five-hundred kilometers.

The source said that the military plans to deploy it at a guided missile headquarters to be established at the nation's center in a couple years. It will also be mounted on 18-hundred-ton-class submarines to be introduced next year.

The source added the military will increase the missile's range to one-thousand kilometers within five years.

Equipped with sophisticated guidance systems, the missile is capable of hitting with accuracy North Korea’s missile bases entrenched deep in the mountains in its rear area.

The Defense Ministry declined to comment on the missile, however, calling it a military secret.
