North Korea may test new missile technology, such as another that uses solid-state fuel, further advancing how effective its missiles would be in a real-life setting. It may also conduct more military exercises around missile launches or launching a volley with multiple missiles going up at once — essentially, allowing it to practice the sort of procedure that would happen in a real launch.
Cotton suggests that if things continue at this rate, North Korea could probably build up to a bigger event: what has been called the “Juche bird,” a test of a missile loaded with a live nuclear weapon, probably above the Pacific Ocean. “A lot of folks in the U.S. have said North Korea still lacks the capability to put it all together,” Cotton said. “North Korea has made several statements suggesting they think they might need to show us once and for all that they do have that capability.”
