There are several websites selling the plans to 3-D print small replicas of the GBU-53/B that look to be the 8-10 inches in length (not the 8 inches in DIAMETER of the real thing).
I think the Yemenis are trying to fool us that they have the real thing.
‘I think the Yemenis are trying to fool us that they have the real thing.”
Now, would those muzz do such a thing?
It also has the yellow/blue flag of Ukraine painted on it.
