A U.S. Air Force E-3 Airborne Warning and Control System (AWACS) aircraft, designated CACHE 51, departed Elmendorf Air Force Base, Alaska, on the evening of September 25th, 2025, to monitor one or more unidentified aircraft near the Alaska Air Defense Identification Zone (ADIZ). The departure was reported via social media at approximately 1:37 AM UTC on September 25th, with tracking and audio feeds made available through services like Flightradar24 and LiveATC. The previous report from September 25th, 2025, detailed a similar monitoring operation by CACHE 51 which departed Elmendorf AFB between 11:37 PM UTC on September 24th and 1:36 AM UTC on September 25th. That report also mentioned a U.S. Air Force KC-135R Stratotanker conducting aerial maneuvers over the Seward Peninsula, near the Bering Strait, during the same period. These activities were speculated to be in response to potential Russian aircraft incursions, referencing a past interception of a Russian Il-20M on August 26th, 2025. No further details regarding the nature of the unidentified aircraft or confirmed incursions have been provided within the current reporting window. Previous unrelated incidents mentioned in an earlier report included two student arrests at Syracuse University for a hate crime during Rosh Hashanah, a fatal shooting at an ICE field office in Dallas, and a hazardous device response in Baltimore County on September 24th, 2025.
