A US Navy MQ-4C drone, callsign BLKCAT5 and hex code AE7815 out of Naval Station Mayport, Florida, conducted a few passes near the Yucatan Peninsula between 5:46 a.m. and 6:15 a.m. UTC on December 19, 2025, according to an X post by @TheIntelFrog (status 2001892610747809845). The post stated, "Must be something interesting to watch tonight on the Yucatan peninsula," noting the drone's repeated activity in the area during this 29-minute reporting window. This observation follows US Southern Command's announcement earlier on December 19 of lethal strikes by Joint Task Force Southern Spear in the Eastern Pacific that killed five narco-terrorists on narco-trafficking routes, directed by Secretary Pete Hegseth, as reported in prior updates.
