“Given that North Korea has been testing large diameter solid rocket motors for the Pukguksong-series (a range of medium-range missiles, including submarine-launched missiles) for several years, it’s been clear that since 2020, a test like this could have come at any time,” says Jeffrey Lewis, director of the East Asia Non-proliferation Program at the James Martin Center for Non-proliferation Studies in California.
