Recently this soon-to-be paywalled Aviation Week article has been popular. Something that caught my attention was the hint of the "RQ-180" having a payload bay.
An ex-U.S. Air Force civilian employee allegedly transmitted classified information about the vulnerabilities of Air Force aircraft to unauthorized people between November 2020 and March 2021.

Recently on eBay, I've seen some weird patches that I strongly suspect tie into this capability. I've attached an image of the patch for reference. The fact it mentions "Hat" is one possible hint that this has something to do with the "Mad Hatters" organization, the same group that is currently flying the RQ-180. The 6 stars could represent the Area 51 operating location. The black shape represents the still unacknowledged platform. The lightning bolt could represent electronic warfare. Last but not least, the bombs could hint at the capability I previously mentioned.
Cheers.
