One photo of Kim reveals a poster on the wall clearly mentioning a missile called "Pukguksong-3," a potential successor to the previous two versions of the missile which were both solid-fuel, medium-range projectiles.
North Korea's desire to build solid-fuel missiles is driven by their need for projectiles they can launch quickly and subtly, said Michael Duitsman, also a research associate at the James Martin Center.
"Solid fuel missiles are much faster to deploy ... a solid fuel missile is always fueled so all they have to do is drive it to the place they want to launch it," he said.
"It's much easier to put into action, much harder to catch before it launches because they're a lot less in terms of launch preparations that could be done."
All ballistic missiles owned by the United States and Russia are solid-fuel models, according to Duitsman.
In another, the North Korean leader stands next to a large copper-colored container, which experts said could be a wound-filament reinforced plastic rocket casing.
… Speaking at a rally in Arizona Wednesday, Trump claimed Kim was "starting to respect us."
"I respect that fact very much. Respect that fact. And maybe probably not, but maybe, something positive could come about. (The media) won't tell you that. But maybe something positive could come about," he told supporters.
US Secretary of State Rex Tillerson has also presented a more conciliatory face to North Korea in recent days, saying the US was open to dialogue with the rogue state.
