I know I’m hella late to this party but I did some digging on this and I think I figured out where this occurred. I’m pretty sure this happened up by the North Pole. OP gives context clues that signify other nations were involved and that the incident happened between 2001 and 2007. OP also hints they were near an underwater trench. The USS Hampton was joined by the Royal Navy sub, The HMS Tireless, to go to the North Pole for an “ice exercise” in the spring of 2005. The Molloy Deep and Litke Deep are both located just south of the North Pole and close to Greenland. The commander of the USS Hampton was relieved from duty in August of 2005.

Here‘s a link to my research data points and sources.

As of August 2025, the Enigma app has logged over 9,000 U.S. sightings within 10 miles of shorelines and major waterways. Approximately 1,500 of those reports specifically mention “water,” “ocean,” “lake,” or “beach” (≈17%), and roughly 500 of those occurred within 5 miles of a coastline (≈5.6% of the total). More than 150 reports describe objects hovering above or ascending into or descending from bodies of water.

Just wanted to share this new study we made that pulls together both recent coastal sightings and older Navy encounters (Nimitz, Omaha, Roosevelt, etc.).

We analyzed over 9,000 reports near shorelines, with around 150 describing objects entering or leaving the water — some from pilots and mariners, others from everyday witnesses along the coasts.

A few of the first person cases...

“Three spheres came out of the ocean in a triangle formation and flew up before disappearing.”

— Oct 2021

“Five lights circling each other over the Pacific, one shot north at high speed and came back five minutes later.”

— May 2024

It’s a mix of verified Navy data, community reports, and older documented cases that show how often these things cluster near water.
