"We can call it a newly developed North Korean-style SLBM. Loading submarines with solid fuel missiles allows prolonged operations underwater."
 
Professor Kim Dong-yup at Kyungnam University's Institute for Far Eastern Studies told KBS that considering the distance submarines travel, the North could have all of South Korea and Japan as well as Guam and Hawaii in its target range.

"Submarines can move as far as Hawaii. It means striking the U.S. mainland is possible. In fact, covert operations are possible by combining the roles of missiles."
 
Experts said that Seoul and Washington should alter its strategy against the North considering the imminence of the SLBM's threat.
