9,000+ Reported 'Underwater UFOs' Off U.S. Coasts — Scientists and Officials Call for Answers

Thousands of Unidentified Submersible Sightings Reported Near U.S. Shores

Enigma — an app that tracks aerial and maritime anomaly reports and brands itself as “the #1 destination for UFO sighting alerts and aerial intelligence” — says it has recorded more than 9,000 reports of unexplained objects off U.S. coastlines since August 2025. Many of those incidents were reported within five miles of shore, with California (389) and Florida (306) recording the highest tallies.

What witnesses are reporting

Users have posted videos and eyewitness accounts describing bright, fast-moving lights and objects emerging from or moving just under the water. One widely shared clip shows two glowing green lights filmed from a boat off Fort Lauderdale, Florida.

How experts describe these phenomena

Marine Technology News and other outlets use the term Unidentified Submersible Objects (USOs) to describe such sightings. The outlet explains:

“Unidentified Submersible Objects (USOs) refer to any object or phenomenon detected underwater that cannot be immediately identified or explained. They are often described as moving at extraordinary speeds, changing direction with extreme precision, and sometimes transitioning between water and air without obvious disturbance — so-called ‘transmedium’ capabilities.”

Historical and military context

These reports are not entirely new. In 2019 the USS Omaha documented an unidentified craft off San Diego that reportedly submerged without a trace; that incident was later confirmed as recorded by the Department of Defense. Retired Navy Rear Admiral Tim Gallaudet, writing in a 2024 report about the broader topic, warned that such technology could jeopardize U.S. maritime security and criticized what he described as limited public disclosure on anomalous, all-domain phenomena.

“The fact that unidentified objects with unexplainable characteristics are entering US water space and the DOD is not raising a giant red flag is a sign that the government is not sharing all it knows about all-domain anomalous phenomena.” — Tim Gallaudet

Expert caution and the need for verification

While dramatic, many app-reported sightings remain unverified. Eyewitness videos and citizen reports can be compelling, but they require corroboration from independent sensors (radar, sonar, satellite) and official investigation to rule out natural, man-made, or sensor-artifact explanations. Several researchers and defense observers have called for greater transparency, standardized reporting, and more rigorous analysis of USO reports to determine whether they pose genuine safety or security risks.

Where this story came from

The account draws on data reported by Enigma and coverage originally published by Surfer (Nov 4, 2025), with contextual reporting from Marine Technology News and commentary from MUFON (Mutual UFO Network) representatives.

Bottom line: More than 9,000 coastal reports have sparked renewed interest in underwater unidentified phenomena. While there are intriguing videos and credible historical incidents, verification and scientific study are needed before drawing definitive conclusions about origin or threat.
