these close ups tell me the plane has either two weapon bays that are right next to each other, like f22, or it has one single weapon bay. Weapon bay doors also seem to be similar to ones on f22 and j20 - each door seems to have a larger part on the outer side of the belly, and a smaller, hinged part that covers the section that's near to the centreline. That smaller part is supported by a rod of some sort that folds the door around the hinge, as needed.
