The Republic of Korea is developing a supersonic cruise missile to defend the country against threats from the navies of neighbouring countries.

The government source said, “Think tanks like the Agency for Defense Development have been developing a supersonic anti-ship cruise missile for some years now.”

“They’re expected to complete development in three to four years at the earliest,” The Chosunilbo quotes the source as saying.

Based on Russia’s Yakhont missile, the missile will have a range of 250km-300km and can achieve speeds of up to Mach 2.5.

The cruise missile can be used to attack aircraft carriers, Aegis ships and other modern submarines.
