So they started developing the Hyunmoo series. The Hyunmoo-3c has a range of 1500km, it is domestically built unlike the previous Hyunmoo missiles which were actually old Nike missiles from 1950s. It's interesting that South Korean engineers added a slot for carrying nuclear warheads (possibly had plans to develop nuclear weapons at some point in the 1970s).
Cruise missiles don't give the same power projection like a ballistic missile tipped with nuclear warhead. It can be intercepted which limits it's reach.
