The weapon was likely a short-range rocket system, or something that was ground tested, said Melissa Hanham, a non-proliferation expert and Director of Open nuclear Network’s Datayo Project.

"These tests help improve their solid-fuel motors and not only is it good for their short-range systems, it would likely make their long-range missiles quicker and more powerful," said Melissa Hanham, a weapons expert and deputy director of the Open Nuclear Network.
