A popular UFO-tracking platform is making waves after recording tens of thousands of mysterious underwater objects off the United States’ coastlines. According to Marine Technology News, users of Enigma, a non-partisan organisation that claims to host the “largest queryable historical sighting database for global UFO sightings”, have logged more than 9,000 unidentified underwater sightings within 10 miles of US shorelines since August 2025.The sightings, categorised as Unidentified Submersible Objects (USOs), refer to any object detected underwater that cannot be immediately identified or explained. Witnesses often describe the USOs as moving at extreme speeds, changing direction with uncanny precision, and even transitioning seamlessly between water and air, a phenomenon experts call transmedium capability.
Coastal hotspots and curious patterns
Since its launch in 2022, Enigma has catalogued nearly 30,000 UFO sightings worldwide, but this new wave of reports suggests a growing focus on what’s happening beneath the surface.Of the 9,000 underwater sightings logged in recent months, around 500 were reported within just five miles of US coastlines, while more than 150 objects were observed hovering above, or plunging into, major bodies of water.Data published by Enigma and reported by Marine Technology News show California and Florida leading the tally, with 389 and 306 sightings, respectively. Several clusters of high activity have been detected near specific coastal zones, prompting both public intrigue and quiet concern among defence analysts.
Experts divided: ‘Either we don’t understand it — or our tech is seeing ghosts’
Author Kent Heckenlively, who wrote Catastrophic Disclosure: Aliens, The Deep State and The Truth, told Fox News Digital that the reports of high-speed underwater craft challenge both science and logic.“That’s one of two things,” he said. “Either that’s something we don’t understand, or our technology is picking up ghosts underwater.”Heckenlively believes the data underscores a long-standing issue: the gap between government disclosure and public knowledge.“I’m sceptical of alien stuff,” he admitted, “but I’m convinced the government is lying to us.”
‘The ocean seems like a great place to hide’
Retired Navy Rear Admiral Tim Gallaudet has long warned that unidentified objects in US waters could jeopardise maritime security. In a 2024 report cited by Fox News Digital, Gallaudet argued that such encounters, including the now-famous 2019 Pentagon video showing an unidentified object diving into the Pacific near the USS Omaha, raise red flags the government hasn’t fully addressed.“Pilots, credible observers and calibrated military instruments have recorded objects accelerating at rates and crossing the air–sea interface in ways not possible for anything made by humans,” Gallaudet wrote, according to Fox News.Heckenlively added that the ocean might be the perfect cover for such phenomena.“If these things are real, the ocean seems like a great place to hide,” he said.
