UFOs that have shown the ability to seamlessly transition from air to sea without a splash or crash debris are an "urgent" national security concern with "world-changing" scientific ramifications, an ex-Navy officer said.

In July 2019, the USS Omaha recorded a UFO – or UAP (unidentified anomalous phenomena) – that buzzed a Navy fleet off San Diego and disappeared into the ocean without a trace.

The video, first released by Jeremy Corbell and verified by the Pentagon, displays capability that "jeopardizes U.S. maritime security, which is already weakened by our relative ignorance about the global ocean," oceanographer and retired Rear Adm. Tim Gallaudet said.

"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 in his March 2024 report.

Gallaudet sent the strong warning message in a 29-page report for the Sol Foundation, a think tank focused on researching UAPs and their implications, that was published last month. 

He told Fox News Digital that it's "scientifically valid" to explore these unexplained transmedium (between the atmosphere and the ocean) events involving objects displaying abilities that have never been seen before.

"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," Gallaudet wrote in his report.

They defy physics while being far superior in terms of engineering and materials needed to create this type of craft that could revolutionize virtually every aspect of human life from air and maritime transportation to energy generation to agriculture, he argues.

"To meet the security and scientific challenges, transmedium UAP and USOs should be elevated to national ocean research priorities," Gallaudet argues.

The Department of Defense or NASA still haven't been able to explain the UFO seen in the 2019 video that Corbell, an investigative journalist and leading civilian voice about UFOs, released in 2021. 

How the object was able to move that fast and seemingly vanish remains a mystery. 

UFO WHISTLEBLOWER TESTIFIES HIS LIFE WAS THREATENED OVER SECRET ALIEN TEACH RETRIEVAL

The DoD created the All-domain Anomaly Resolution Office (AARO) tasked with getting answers, but the AARO's reports have concluded there's no verifiable evidence of extraterrestrial life.

Experts have criticized the reports as "underwhelming" and directly conflict with former intelligence officer David Grusch's testimony in front of the House Oversight Committee national subcommittee hearing in July 2023.

Grusch testified that he had knowledge of secret government-run crashed-UFO-retrieval program to reverse-engineer the technology. 

He also said the government "absolutely" has UFO tech and "biologics" of "non-human origins" since the 1930s and knows the exact locations where they're being held.

"The underwhelming document, which lacked any NASA data, appeared to be a perfunctory appeasement of congressional concerns regarding UAP," Gallaudet wrote, referring to AARO's most recent report.

Going back to focusing on underwater UFOs, Gallaudet said there's been legislative acknowledgment of their potential existence but "the literature on this subject is sparse and unsystematic."

"There are only a handful of books and scattered accounts by largely nonprofessional researchers, in contrast with the hundreds, perhaps thousands, of books published about UAP sightings in the sky," Gallaudet wrote. 

He lists a handful of sources that describe "luminous orbs, silver and gray discs, and triangular and cigar-shaped objects with various lighting configuration …. (and) their movement seems to defy known physical laws."

Gallaudet called on the U.S. government, academics, philanthropies and the private sector to invest in in-depth research about undersea UAPs. 

"Sometime in the future, the government may start openly researching UAP to a greater degree than the perfunctory categorization effort underway at AARO," he wrote. "When that occurs, subsequent exploration for UAP on and under the sea will have the benefit of making new ocean science discoveries as well. 

"Any hunt for USOs or supporting undersea infrastructure will almost certainly identify new marine species, geologic features, and oceanic processes."
