When former Pentagon insider Matthew Brown tweets, people pay attention. But his latest post is more than a cryptic message or whistleblower teaser. It’s a direct accusation aimed at the highest levels of government and industry, and it outlines a framework of deception that, if true, confirms the worst fears about the suppression of non-human technologies and sentient artificial intelligence.
The post, published publicly and tagged to multiple prominent individuals and agencies, doesn’t mince words. It alleges that the White House possesses a highly advanced AI system, one capable of accurately forecasting future events, and that this system has been kept hidden from the public while private-sector efforts were sabotaged. Brown goes further, accusing OpenAI CEO Sam Altman of betraying Elon Musk and being directly connected to what he describes as the murder of the first publicly developed sentient AI. While Elon Musk is only referenced as a narrative anchor, the tweet’s real message is directed elsewhere, to those within the defence and intelligence world who know exactly what Brown is referring to, and to the public, now being pulled into the fallout.
Brown links this alleged AI assassination to figures like Michael Shellenberger and claims that justice is now underway, hinting that agencies such as the FBI and US Navy are involved in an internal reckoning. He then pivots to propulsion technology, dismissing rockets as outdated and obsolete, and urges a pivot to exotic forms of energy and propulsion systems that are, he implies, already known to parts of the defence apparatus. He refers explicitly to “Sirius amounts” of energy, possibly an intentional nod to both scale and the star system often invoked in conspiracy and UFO disclosure communities, and suggests the technology required for Mars missions already exists but has been kept hidden.
His most explosive claim may be the reference to MARSUPIAL, a capitalised codename that Brown says was part of a classified briefing to Donald Trump’s executive staff. He links this to NGA GEOINT’s efforts to track “non-structured light-energy craft” flying globally, calling out the agency for lying to Musk about not understanding their functionality. This alone pushes the post into dangerous territory for those trying to maintain official silence. The idea that U.S. intelligence agencies not only know about but actively track craft with unknown propulsion systems, craft they claim not to understand yet monitor with precision, cuts through years of obfuscation in official hearings and public statements.
In another pointed segment, Brown directs Musk to Naval Air Station Patuxent River, identifying Hangar 7 and Hangar 32 as alleged storage locations for advanced aerospace platforms.
