The Korean Central News Agency (KCNA) claims that North Korea has successfully tested a solid-fuel engine for a new intermediate-range hypersonic missile. The intended final missile will have sufficient range to strike U.S. targets once completed.
Guam is among the targets within the new missile’s range. Experts have said such a missile can also “reach” Alaska. A range adjustment can be used to strike closer targets, such as U.S. military installations on Japan’s Okinawa island.
