“Unmanned X Systems” Breaches at U.S. Air Force Plant 42, Home to B-21 Raider and Other Top Secret Programs

Newly obtained documentation from the United States Air Force (USAF), acquired by Liberation Times, reveals seven recorded instances of drone incursions over USAF Plant 42 and Palmdale Regional Airport, California, between 2 August and 9 August 2024.
The documentation shows official USAF reports describing rotary-wing drones with blinking lights and camera systems repeatedly hovering over sensitive areas, prompting patrol responses, off-base pursuit attempts, and coordination with the Federal Aviation Authority (FAA), with assessments suggesting the drones operated beyond typical hobbyist capabilities.
The reports refer to the objects seen as UXS, meaning Unmanned X Systems, a broad military designation for unmanned aerial, ground, or maritime systems.
…
Alarmingly, throughout all seven nights of drone activity, no countermeasures were operational, leaving the objects completely unchallenged.
Commander reports add, ‘currently there is no authorized detection or defeat capability available to the Defense Force.’
That contradicts reporting from Breaking Defense in 2022, when officials acknowledged that the facility had a ‘geo-fence’ that ‘knocks out small drones that users attempt to fly overhead.’*
Such was the alarm, Los Angeles Sheriff’s Department helicopters were brought in to assist on two separate occasions.
Despite the frequency and persistence of the incursions, the reports state that no photos or videos were recorded.

“Alarmingly, throughout all seven nights of drone activity, no countermeasures were operational,”
Are we supposed to be alarmed? Should we be? Is some AF base going to be another Israel some day? Is it just another test, testing surveillance performance, drone performance, drone pilot performance? Are bored AF guys playing games, my drone can get to the target before your drone?

Wherever I see an X, questions arise.
Google AI says “companies like Meta and Microsoft have registered trademarks for the letter “X” in relation to their products, meaning they have exclusive rights to use the letter in specific contexts within their respective industries, like for social media or gaming consoles.”
Or Space X.
