On August 25, 2025, retired U.S. Navy Rear Admiral Tim Gallaudet raised alarms about unidentified submerged objects (USOs), also known as underwater UFOs, asserting they pose a legitimate threat to U.S. maritime security.
In a detailed report for Popular Mechanics, Gallaudet, a former Oceanographer of the Navy, highlighted compelling evidence from military encounters with transmedium objects—capable of seamless transitions between air and water—that defy known physics and engineering capabilities.
The article, citing incidents like the 2019 USS Omaha sighting, underscores growing calls for transparency and research into these phenomena, as experts warn their advanced technology could jeopardize national security amid global tensions.
Evidence of Transmedium USOs

Gallaudet, who also served as acting NOAA administrator from 2017 to 2021, pointed to several documented incidents as evidence of USOs.
In July 2019, the USS Omaha, operating off San Diego, captured infrared footage of a spherical object moving swiftly over the Pacific before vanishing into the ocean without a splash, wake, or debris, per Popular Mechanics.
The Pentagon later verified the footage, which stunned observers due to the object’s behavior, defying hydrodynamic principles.
Gallaudet noted, “It’s not that they break the laws. It’s that they demonstrate engineering capabilities we haven’t yet developed,” emphasizing the object’s ability to transition mediums without slowing.
Another key incident occurred in November 2004, when F/A-18 Hornet pilots from the USS Nimitz recorded a Tic Tac-shaped unidentified anomalous phenomenon (UAP) darting over the Pacific, captured via the Advanced Targeting Forward-Looking Infrared (ATFLIR) system.
Retired Navy Commander David Fravor, a witness, reported the object hovering above a mysterious underwater disturbance before accelerating at unprecedented speeds.
A 2013 sighting off Aguadilla, Puerto Rico, filmed by U.S. Customs and Border Patrol, showed a spherical object traveling at 40 to 120 miles per hour, entering and exiting the Atlantic without deceleration, and splitting into two parts.
Gallaudet, in a 2024 Sol Foundation white paper, called such transmedium capabilities a “world-changing” concern.
National Security Implications
Gallaudet warned that USOs’ ability to operate undetected in U.S. waters threatens maritime security, already strained by limited knowledge of the global ocean.
He cited the 2019 USS Omaha incident as evidence of objects that “jeopardize U.S. maritime security,” noting the Department of Defense’s (DoD) lack of urgency as a sign it may not be sharing all it knows.
The DoD’s All-domain Anomaly Resolution Office (AARO), established in 2022 to investigate UAPs, reported no evidence of extraterrestrial technology in its 2024 findings, but Gallaudet and others criticized the reports as “underwhelming.”
Former intelligence officer David Grusch’s 2023 congressional testimony, claiming knowledge of a secret UAP retrieval program, further fueled transparency demands, per Fox News.
The potential for USOs to collide with submarines, as seen in the 2005 USS San Francisco and 2021 USS Connecticut crashes with underwater seamounts, underscores operational risks.
Gallaudet argued that studying USOs could also uncover new marine species or geologic features, but the primary concern remains their unknown intent and advanced capabilities.
He suggested these objects could originate from extraterrestrial sources or an ancient intelligent species living beneath the seafloor, hypotheses that remain unproven but warrant investigation.
Public and Expert Reactions
The issue has gained traction among experts and the public.
Ryan Graves, a former Navy pilot who reported UAPs in 2014, founded Americans for Safe Aerospace to advocate for pilot safety and transparency, testifying at a 2023 House Oversight Committee hearing alongside Fravor and Grusch.
On X, @PopMech posted on August 25, 2025, highlighting Gallaudet’s claims: “Navy Officer Says Underwater UFOs Are Legitimate Threats. The Evidence Is Hard to Ignore,” reflecting public interest.
@NavyAdvancement also echoed this, emphasizing the Navy’s concern.
Critics like AARO director Jon Kosloski maintain no extraterrestrial evidence exists, attributing sightings to mundane causes like drones or balloons.
However, lawmakers, including Rep. Andy Ogles, stressed the need for government transparency, stating, “There is something out there,” during a November 2024 hearing.
The 2022 National Defense Authorization Act expanded UAP definitions to include transmedium phenomena, signaling official concern.
Implications for U.S. Policy
The growing focus on USOs coincides with broader national security challenges, including Russia’s attacks on Ukraine and economic pressures from Trump’s tariffs, per Reuters.
With Trump’s approval rating at 39% per an ABC News/Washington Post/Ipsos poll, his administration faces pressure to address UAP transparency, especially after promising to release Epstein files.
Gallaudet’s call for prioritizing USO research could push the DoD to enhance ocean surveillance, potentially impacting naval operations and global security strategies.
As the 2026 midterms approach, public and congressional demands for clarity on UAPs and USOs will likely intensify, challenging the administration to balance skepticism with the need to address unexplained phenomena that could threaten U.S. waters.
