Bryan Clark, a retired U.S. Navy undersea warfare officer and analyst the Center for Strategic and Budgetary Assessments, suggested that while the requisite missile ejection technologies are difficult to master, it is probably not beyond the capabilities of North Korean engineers.
“Since they have ballistic missiles and submarines the technically-challenging part is the launch mechanisms,” Clark told The National Interest.
“It needs to eject the missile from the ship and into the air without damaging the missile, and the missile needs to start up after it leaves the water. Those technologies and well-established and North Korea’s engineers can probably build something that will work.”
