Overview
- Enigma reports more than 9,000 unidentified submersible sightings within 10 miles of U.S. shorelines since August 2025.
- Roughly 500 of those reports were within five miles of land, with over 150 involving objects seen over water or entering or emerging from it.
- Coastal concentrations are led by California and Florida, which account for 389 and 306 reports respectively on the platform’s public maps.
- The dataset is crowdsourced and largely unverified, though the Pentagon has previously verified 2019 footage of an object diving near the USS Omaha.
- Retired Rear Adm. Tim Gallaudet warns of potential maritime security risks and presses for transparency, and Enigma and the Pentagon did not provide comment.
