USS Omaha USO Incident

On July 15, 2019, the USS Omaha Combat Information Center (CIC) recorded footage of a spherical UAP approximately 6 feet in diameter tracking alongside the ship before entering the ocean off the coast of San Diego. The object showed no propulsion signature, no exhaust, and exhibited stable controlled flight at low altitude. It entered the water cleanly, with no impact splash consistent with its observed velocity — a behavior characteristic of vehicles designed for trans-medium travel. The USS Omaha is a littoral combat ship equipped with advanced sensor suites.

The event was part of a larger pattern of UAP encounters by naval vessels in the Pacific in 2019. Ship radar tracked multiple objects in the area over a period of hours. A submarine was reportedly dispatched to search the waters beneath the ship's position after the object submerged; it found nothing. Multiple crew members observed the incident directly and via sensor feeds in the CIC.

The footage was leaked to filmmaker Jeremy Corbell and journalist George Knapp in 2021 and published. Pentagon spokesperson Sue Gough subsequently confirmed in a statement to CNN that 'the video was taken by Navy personnel' and that 'the video is authentic.' Gough's statement did not address the nature of the object or the results of the submarine search.

The USS Omaha incident is one of the most compelling documented cases of trans-medium UAP behavior on record — an object observed transitioning from aerial to aquatic operation without deceleration, impact behavior, or structural compromise. The event was later referenced in AARO's public reports as one of the cases under active investigation. The submarine's failure to locate any submerged object despite rapid dispatch deepens the case's unresolved status.
