# Air Force veteran claims secret UFO facility spans multiple city blocks underwater

### Overview

An Air Force veteran has alleged that a **secret facility linked to unidentified flying objects exists on the ocean floor**, claiming it is large enough to span “multiple city blocks.” The allegation was made during an appearance on Joe Rogan’s podcast, according to a Daily Mail report published October 1, 2026.

The claim has attracted attention because it places a familiar theme in UFO lore—hidden government or nonhuman installations—beneath the sea rather than on land or at a conventional military site. However, **the material available for this report contains no independently verified evidence** supporting the existence of such a facility.

### The Allegation

The veteran’s reported description suggests a substantial underwater complex, rather than a small research station or temporary structure. The phrase “multiple city blocks” is a broad comparison and does not establish the facility’s exact dimensions, location, construction, ownership or purpose.

The source material does not provide publicly verifiable coordinates, photographs, engineering records, sonar data, procurement documents or testimony from additional witnesses. It also does not identify any official agency that has acknowledged the alleged site. As a result, the claim remains an unsubstantiated account rather than a confirmed discovery.

The report’s headline references former intelligence official David Grusch, who became widely known after alleging in 2023 that the U.S. government possessed nonhuman craft and had conducted retrieval programs. Grusch’s allegations prompted congressional interest, but **public hearings and reporting have not established that an underwater base exists**. It is not clear from the supplied material whether the veteran’s account is connected directly to Grusch’s claims or merely appears in the same broader discussion.

### Broader UAP Context

Claims involving secret UFO facilities have emerged amid increased public and congressional scrutiny of unidentified anomalous phenomena, or UAP. In the United States, military personnel and former officials have testified that some aerial observations remain unexplained. Those unresolved cases, however, do not by themselves demonstrate extraterrestrial activity or prove the existence of hidden installations.

The Pentagon’s All-domain Anomaly Resolution Office has said that many reported sightings can be attributed to ordinary objects, sensor limitations, misidentification or incomplete information. In its historical review, the office reported finding no verifiable evidence that the U.S. government or private industry had recovered extraterrestrial technology. Those findings do not resolve every individual sighting, but they underscore the distinction between **unexplained evidence and evidence of alien technology**.

### What Remains Unknown

A facility occupying several city blocks beneath the ocean would likely require major logistical, financial and engineering support. Depending on its depth and location, such a structure could involve specialized power systems, life-support infrastructure, access routes, communications equipment and extensive maintenance operations. None of those elements has been documented in the information provided.

For now, the veteran’s statement should be treated as an allegation requiring corroboration. **No independent confirmation, official documentation or physical evidence has been presented** to substantiate the reported underwater UFO base. Further assessment would require specific details that can be checked against maritime records, satellite or sonar observations, government documents and testimony from identifiable, independent sources.
