9,000 Mysterious Underwater Objects Detected Along US Coastlines Spark Navy Alarm
Something strange is happening beneath American waters. A popular UFO-tracking app has recorded thousands of sightings that suggest the mystery extends far below the surface, into depths where conventional explanations break down.

Enigma, a platform that bills itself as the largest queryable historical sighting database for global UFO sightings, has logged over 9,000 mysterious encounters within 10 miles of US shorelines and major bodies of water since launching in late 2022. More than 500 of those sightings occurred within 5 miles of coastlines. Over 150 reports describe objects hovering above waterways or descending into them.
Enigma’s total database now contains reports on more than 30,000 Unidentified Flying Objects and Unidentified Anomalous Phenomena. Yet what sets recent findings apart is not what people saw in the sky, but what they witnessed emerging from or plunging into the ocean.
Maps released by Enigma show clusters of orange dots concentrated along both the Atlantic and Pacific coasts. Reports describe objects rising from the depths or disappearing beneath waves without leaving a ripple. Some witnesses captured footage. Others relied on calibrated military equipment that recorded movements science cannot yet explain.
Unidentified Submersible Objects: UFOs That Dive Beneath Waves
Unidentified Submersible Objects, known as USOs, represent the aquatic counterpart to aerial phenomena. Any object or phenomenon detected underwater that cannot be identified or explained falls into this category.
What makes USOs particularly baffling is their apparent ability to transition between environments. Witnesses describe objects moving from air to water without the expected physical consequences. No splash. No debris. No wake or wreckage. Experts call these “transmedium” capabilities, and they challenge fundamental assumptions about physics and engineering.
Reports come from varied sources. Medieval sailors documented encounters. Modern Navy sonar operators track contacts. Civilian observers capture footage on phone cameras. Calibrated military instruments record data that defies conventional interpretation.
Eerie Green Lights Captured Moving Below Ocean Surface
Among the most striking evidence submitted to Enigma are videos showing mysterious green lights traveling beneath ocean surfaces. One clip, recorded in the Fort Lauderdale River in Florida, captures two bright green lights moving underwater against a backdrop of buildings.
Other reports describe similar phenomena. Objects emerge from deep water with no warning. Craft plunge into the sea without producing the splash that physics would demand. Luminous forms travel beneath waves at speeds that leave witnesses struggling for explanation.
Phone camera footage provides some documentation, but the quality varies. Military instruments offer more reliable data, yet even that information raises more questions than it answers. What technology allows a seamless transition between air and water? What propulsion system leaves no trace?
California and Florida Lead Nation in Underwater Anomaly Reports
Geographic patterns emerge from Enigma’s database. California recorded 389 USO reports, the highest in the nation. Florida came in second with 306 reports. Both states rank among the top three for ocean coastline length.
Enigma’s maps plot sightings as clusters of orange dots running up and down both coasts. Concentrations appear near shipping lanes, naval training zones, and busy maritime routes. Whether this pattern reflects where objects actually appear or simply where more people are present to observe them remains unclear.
Marine Technology News analyzed the data and noted how sightings correlate with coastal population density and maritime traffic. Yet some reports come from remote areas where few witnesses would be expected. Others emerge from military exercises conducted far from civilian observation.
USS Omaha Incident Raises Alarm Bells at Pentagon
One case stands out for its documentation and official verification. In July 2019, the Navy destroyer USS Omaha tracked a spherical object off the coast of San Diego. Video footage shows the craft flying over the ship before it plunges into the Pacific Ocean and vanishes.
No wake appeared. No debris surfaced. Sonar detected nothing. One moment, the object existed on multiple forms of tracking equipment. The next moment, it was gone.
Filmmaker Jeremy Corbell obtained the footage and released it to the public in 2021. Pentagon officials later verified the video as legitimate, Naval-recorded anomalous phenomena. Official confirmation that the military captured this event on multiple systems lent credibility to what might otherwise be dismissed.
Officers aboard the Omaha could not explain what they witnessed. Analysis of the footage provided no conventional explanation. Whatever the object was, it possessed capabilities that surpassed known human technology.
Retired Admiral Calls USOs “World-Changing” National Security Threat
Retired Rear Admiral Tim Gallaudet served as an oceanographer and acting head of the National Oceanic and Atmospheric Administration. His background combines military experience with scientific expertise. When he speaks about underwater anomalies, people in defense circles listen.
Gallaudet authored a March 2024 report for the Sol Foundation, a think tank dedicated to studying unidentified anomalous phenomena. His 29-page analysis pulls no punches about the implications. “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,” Gallaudet wrote.
He describes the capabilities documented in cases like the USS Omaha incident as threats that “jeopardize US maritime security, which is already weakened by our relative ignorance about the global ocean.” For a former high-ranking Naval officer to make such statements publicly suggests deep concern about what remains hidden.
Gallaudet believes these phenomena could have what he terms “world-changing” ramifications. Whether the objects represent foreign military breakthroughs or something beyond human technology entirely, ignoring them creates dangerous gaps in American defense capabilities.
Objects Defy Physics With Impossible Speed and Maneuvers
Technical analysis of reported capabilities reveals why experts like Gallaudet express alarm. Veteran Navy sonar operator Aaron Amick has described fast mover contacts that occasionally appear on sonar systems. He characterizes them as “so quick that you can’t measure the speed.”
Gallaudet’s report documents even more extreme examples. “Pilots, credible observers and calibrated military instrumentation have recorded objects accelerating at rates and crossing the air-sea interface in ways not possible for anything made by humans,” he wrote.
Current understanding of physics and engineering cannot account for several reported characteristics. Objects accelerate at rates that would destroy any known aircraft or submarine. Craft transitions between air and water without the structural damage that pressure differentials would cause. Propulsion systems leave no thermal signature, no exhaust, no visible means of thrust.
Military instruments designed to track conventional threats capture data on these objects but cannot explain what the data represents. Pilots report visual confirmation of movements their training tells them should be impossible. Observers on ships watch objects perform maneuvers that violate basic principles of inertia and momentum.
Medieval Chronicles to Modern Radar: Centuries of USO Reports
Historical records suggest underwater anomalies are not new. Accounts dating to the 11th century describe similar phenomena. Witnesses in England reported a fiery object that “revolved, ascended on high, and then descended into the sea” repeatedly off the Northumberland coast.
In 1825, English naturalist Andrew Bloxam sailed aboard the HMS Blonde when he witnessed something extraordinary. A red, luminous orb rose from the sea. Bloxam recorded his observations: the object appeared “the color of a red-hot cannon shot” and shone bright enough that “a pin might be picked up on deck.” It rose and fell twice before vanishing.
Reports continued through subsequent centuries. Sailors across different eras and oceans described lights beneath waves, objects emerging from depths, and craft that moved between air and water. Whether these accounts describe the same phenomena modern instruments now detect remains open to debate.
What changed is not necessarily the frequency of events but the quality of documentation. Medieval sailors had only their eyes and written testimony. Modern observers have radar, sonar, infrared cameras, and satellite tracking. Yet even with superior technology, explanations remain elusive.
Gallaudet Testifies Before House Oversight Committee
In November 2024, Gallaudet appeared before the House Oversight Committee to discuss his findings and concerns. He made clear that he views these incidents as serious national security risks that demand systematic investigation.
His testimony drew on his 29-page Sol Foundation report, which detailed a documented pattern of phenomena reported by credible sources using calibrated equipment. Gallaudet called for transmedium UAP and USOs to be elevated to national ocean research priorities.
Congressional response to his testimony varied. Some members pressed for more transparency from defense agencies. Others remained skeptical. All acknowledged that if foreign adversaries possess the technology Gallaudet described, American maritime security faces threats of unprecedented scale.
Pentagon Verified Footage But Questions Remain Unanswered
Pentagon officials confirmed the USS Omaha video as authentic Naval footage. Yet confirmation came without explanation. Government acknowledgment that something unusual happened does not equal disclosure about what that something was.
Some defense officials point to the All-domain Anomalous Resolution Office (AARO) as evidence that the Pentagon takes these reports seriously. Critics argue that AARO operates with insufficient resources and transparency to address the scope of the mystery.
Gallaudet suggests the government “is not sharing all it knows about all-domain anomalous phenomena.” Whether this reflects classification concerns, lack of understanding, or deliberate concealment remains contested. What seems clear is that whatever information defense agencies possess, they have not made it available to the public or even to Congress in full.
Scot Christenson, director of the US Naval Institute, wrote in a 2022 editorial for Naval History Magazine that aerial phenomena pose less documented danger than their underwater equivalents. While no documented damage to a plane caused by a UFO exists on record, mysterious sea creatures and USOs have presented the Navy with the greatest hazard.
Maritime operations face unique vulnerabilities. Submarines depend on stealth and sensor superiority. Surface vessels require awareness of their environment. Commercial shipping relies on predictable ocean conditions. Objects that move through water at extreme speeds, appear and disappear without warning, and possess capabilities that sensors struggle to track create operational hazards regardless of their origin.
Advanced Foreign Military Tech or Something Beyond Human Capability
Two primary explanations compete for attention. Either foreign adversaries, likely China or Russia, have achieved breakthrough advances in underwater vehicle technology, or the phenomena represent something science cannot yet categorize.
Gallaudet leans toward the latter interpretation. He insists that speeds and maneuvers reported “go far beyond current human technology.” Known engineering principles cannot account for craft that transitions between air and water without structural compromise. No propulsion system in any nation’s arsenal can produce the acceleration rates documented by military instruments.
Yet dismissing foreign technology entirely carries its own risks. If adversaries have made unexpected leaps in capability, assuming the objects represent something beyond human origin could be a dangerous miscalculation.
Ocean Remains Least Understood Domain on Planet
Gallaudet often notes an ironic reality: “We know more about the surface of Mars than our own deep sea.” Ninety-five percent of Earth’s oceans remain unexplored. What exists in those depths largely remains unknown.
Scientific understanding of deep ocean environments remains limited by the extreme challenges of studying them. Pressure, darkness, and vast distances make observation difficult. Even with modern technology, mapping ocean floors and monitoring underwater activity requires resources most nations cannot deploy comprehensively.
Maritime ignorance creates security vulnerabilities. Objects could operate in ocean depths for extended periods without detection. Technology could be tested in deep water, far from observation. Bases or facilities could exist where no surveillance reaches. Whether USOs exploit these gaps or simply operate in spaces where humans rarely look remains unknown.
Americans Left Wondering About Deep Sea Mysteries
Enigma’s database continues growing. More reports arrive weekly. Patterns emerge, but explanations do not. California and Florida lead in sightings, but objects appear along coastlines nationwide. Military personnel report encounters. Civilian observers capture footage. Instruments record data that challenge interpretation.
Whether USOs represent advanced foreign military technology, natural phenomena misunderstood, or something science has yet to categorize, one fact remains: thousands of reports describe objects moving through American waters in ways that current understanding cannot explain. Gallaudet and others argue that ignoring the pattern creates security risks. Skeptics counter that most sightings likely have mundane explanations once properly investigated.
What seems certain is that the ocean keeps its secrets well. As long as depths remain largely unexplored and surveillance remains limited, mysteries will persist. Whether those mysteries eventually yield to scientific explanation or force humanity to reconsider what’s possible remains to be seen.
For now, thousands of orange dots mark Enigma’s maps. Thousands of reports describe the inexplicable. And beneath American waters, something continues to move through the deep.
