CHICAGO, November 4, 2025 – A non-partisan organization tracking reports of unexplained aerial phenomena has logged a dramatic increase in unidentified underwater incidents off the United States coastline, raising both public curiosity and quiet alarm among national security observers. Since August 2025, the platform Enigma, which maintains a vast digital archive of historical unexplained sighting reports, has processed over 9,000 accounts of anomalous activity near U.S. shores, focusing attention on a new category of event: Unidentified Submersible Objects (USOs).

The sudden spike in sightings has shifted the focus from transient high-altitude observations to persistent, fast-moving occurrences beneath the waves. According to data published by Enigma, these reports frequently describe objects exhibiting hyper-velocity travel, abrupt and precise maneuvers, and in approximately 150 instances, demonstrating a ‘transmedium’ capability—moving seamlessly between the underwater environment and the air.

Alarming Clusters Near Coastal Hubs

The data indicates the USO sightings are not random, but concentrated in specific coastal zones. California leads the tally with 389 reports, closely followed by Florida with 306. These clusters have generated intense public discussion and attracted scrutiny from specialized media outlets, including Marine Technology News, which first reported the scale of the underwater submissions.

USOs are defined as underwater detections that defy immediate, conventional explanation. Retired U.S. Navy Rear Admiral Tim Gallaudet, citing a 2024 analysis, has previously warned that unidentified craft operating near U.S. maritime boundaries pose a potential threat to national security. He points to verified military and pilot recordings, such as the widely discussed 2019 incident near the USS Omaha, where objects demonstrated rapid acceleration and the ability to cross the air-sea boundary in ways that appear to exceed current known human technology.

“When we see objects moving at impossible speeds and then diving into the ocean without deceleration, it demands serious governmental investigation,” Admiral Gallaudet noted in a recent statement, emphasizing the risk to U.S. naval operations and intelligence gathering.

Divergent Interpretations of the Phenomena

Interpretations of the Enigma data vary significantly across the scientific and defense communities. Some experts caution against premature conclusions, suggesting that many reports could be artifacts of sophisticated naval or commercial sensor interference, or novel but terrestrial natural phenomena.

Author and researcher Kent Heckenlively, known for his work on governmental secrecy, told Fox News Digital that reports of ultra-fast underwater movements strain common scientific understanding. While acknowledging the potential for instrument anomalies, Heckenlively suggested that if the reports are genuine, the Earth’s vast oceans would offer an ideal, discreet refuge for advanced non-human craft. He stressed that the persistent backlog of unexplained incidents underscores a significant communication gap between official governmental knowledge and public awareness.

Key Characteristics of USO Reports:

• Extreme Velocity: Objects reported moving at exceptionally high speeds underwater.
• Precision Maneuvering: Executing sudden, sharp changes in direction.
• Transmedium Capability: Seamless transition from water to air, or vice versa.

Calls for Greater Transparency and Verification

The recent surge in underwater incident reports marks a significant evolution in documentation practices, reflecting a broader trend where observers are increasingly focused on activity beneath the surface. While Enigma’s database spans tens of thousands of global events, the localized intensity of the U.S. coastal USO reports has intensified calls from advocacy groups and certain political figures for clearer government communication and more thorough, instrument-based verification efforts.

The demand is growing for established scientific bodies and national security agencies to publicly disclose any high-fidelity sensor data—such as radar, sonar, or hydroacoustic recordings—that might corroborate the thousands of recent eyewitness accounts, ensuring transparency on activity near critical U.S. infrastructure and defense zones. The focus remains on determining whether these USOs represent a genuine technological threat, misidentified natural occurrence, or simply instruments operating at the limit of their calibration.
