USS Omaha Transmedium Spherical UAP

What Happened

On the night of July 15, 2019, approximately 17 nautical miles off the coast of San Diego, California, crew members stationed inside the Combat Information Center (CIC) aboard the littoral combat ship USS Omaha (LCS-12) monitored and recorded an anomalous unidentified aerial object using the ship's shipboard AN/KAX-2 Forward Looking Infrared (FLIR) optical sensor system.

The thermal video footage, spanning approximately two minutes, depicts a dark, spherical object traversing horizontally above the surface of the Pacific Ocean. Unlike conventional fixed-wing aircraft or rotary-wing drones, the object displayed no visible aerodynamic control surfaces, wings, rotor blades, vertical stabilizers, or thermal exhaust plumes from internal combustion or jet propulsion systems. Sensor telemetry recorded on the display screen indicated the object was roughly six feet in diameter and traveled at speeds ranging between 40 and 138 knots (approximately 46 to 158 miles per hour) against prevailing ocean winds.

During the terminal phase of the recorded encounter, the sphere descended at a steady, controlled rate toward the water's surface. Audio recorded inside the Combat Information Center captures watchstanders observing the object's flight profile, noting its coordinates, wind velocity, and altitude. As the sphere reached sea level, it vanished beneath the ocean surface without bouncing, shattering, skipping, or producing any detectable hydrodynamic thermal wake or explosive spray. A crew member in the background is clearly heard declaring: "It splashed! Mark bearing and range."

Following the water entry, the USS Omaha deployed surface lookouts and initiated an immediate sonar search. Subsequent investigative records released through Freedom of Information Act (FOIA) disclosures indicated that a submarine was tasked to assist in locating wreckage or sunken hardware in the surrounding operating area. The search effort recovered no wreckage, floating fragments, battery housings, oil slicks, or physical debris whatsoever.

Witnesses and Sensor Evidence

The encounter is documented by multiple independent military observation layers across the USS Omaha and affiliated vessels operating within the Southern California Offshore Training Complex during July 2019. In addition to the FLIR thermal sensor, shipboard radar systems tracked multiple unidentified contacts operating within controlled naval warning airspace over successive nights between July 14 and July 17, 2019.

Investigative filmmaker Jeremy Corbell obtained and publicly released the two-minute video sequence in May 2021. On May 27, 2021, Pentagon spokesperson Susan Gough officially confirmed that the video footage was recorded by U.S. Navy personnel aboard the USS Omaha and verified that the Unidentified Aerial Phenomena Task Force (UAPTF) had integrated the recording into its ongoing intelligence investigation.

Declassified naval records, including Navy deck logs and command briefing slides from the Chief of Naval Operations (CNO), confirm that multiple littoral combat ships and guided-missile destroyers—including the USS Omaha, USS Kidd, USS Rafael Peralta, and USS John Finn—encountered recurring formations of unidentified objects operating in warning areas during mid-July 2019. Deck logs noted low-visibility ambient nighttime conditions, overcast cloud layers, and persistent radar targets maneuvering between 100 feet and several thousand feet in altitude.

Crucially, the USS Omaha recording captured transmedium motion: the theoretical capacity of an object to transit seamlessly between atmospheric flight and oceanic submersion without sustaining structural damage or undergoing significant deceleration. In modern naval warfare, transmedium vehicles present acute challenges because defense architectures typically optimize sensor coverage and weapons systems for either aerospace defense or subsurface anti-submarine warfare, rarely an integrated continuum of both domains.

Official Investigations

The incident was initially investigated by the UAPTF under the Office of the Under Secretary of Defense for Intelligence and Security (OUSD(I&S)). The task force categorized the USS Omaha video as an authentic military capture and evaluated whether foreign adversary surveillance technologies, commercial drone incursions, or covert domestic platforms could explain the sightings.

In the June 25, 2021 ODNI preliminary assessment on UAP, the intelligence community noted that several high-quality UAP observations appeared to demonstrate anomalous flight characteristics, including abrupt transitions between atmospheric and oceanic environments. While the report did not publicly identify the USS Omaha by name in unclassified annexes, the encounter served as a prime exemplar of multi-sensor military documentation.

In July 2022, Congress established the All-domain Anomaly Resolution Office (AARO) to centralize all Defense and intelligence UAP data. Under Congressional mandate, AARO specifically includes "transmedium" phenomena within its statutory scope. In public hearings before the Senate Armed Services Subcommittee on Emerging Threats and Capabilities, AARO leadership confirmed ongoing technical studies into drone swarms encountered by Navy surface vessels off California in 2019, while noting that objects exhibiting genuine transmedium capabilities require rigorous, multi-sensor calibration before exotic propulsion hypotheses can be evaluated.

Proposed Explanations

Uncrewed Aerial Vehicle / Drone Incursion: Skeptics and defense analysts argue that commercial or adversarial drones could explain many of the 2019 California offshore sightings. Advanced quadcopters or fixed-wing uncrewed aerial systems (UAS) operating from nearby commercial fishing vessels or cargo ships in international shipping lanes could surveil naval exercises. However, standard commercial drones lack the battery endurance to operate for hours 17 miles offshore in maritime winds, and sinking into the ocean without debris does not explain why no flotation buoys or wreckage were recovered.

Optical Illusion and Wave Concealment: Skeptical researchers, including Mick West, suggested that the sphere might not have entered the water, but rather dipped below the visual horizon or slipped behind rolling ocean swells while drifting with the ambient wind. Under this hypothesis, thermal inversion or distant horizon geometry created the illusion of submersion. Navy analysts and sensor operators countered that the FLIR system tracked range and depression angles directly, indicating real physical descent rather than horizon occlusion.

Balloons or Targeted Radar Reflectors: Another mundane hypothesis suggests a weather balloon or radar target deployed during fleet exercises drifted into the vessel's operational sphere and deflated upon ocean contact. While radar targets explain passive returns, they cannot actively maneuver, maintain consistent airspeeds against prevailing currents, or account for the multi-day swarm activities documented across adjacent destroyers.

Classified Foreign or Domestic Submersible Drones: A technological hypothesis posits that a nation state—such as China, Russia, or a proprietary U.S. black project—tested hybrid aerial-aquatic drones (HAUVs). Several aerospace research institutions have patented designs capable of transitioning between flight and diving. However, current known prototypes remain fragile, operate at modest speeds, and possess minimal range, contrasting sharply with the robust operational capabilities observed near naval carrier groups.

Current Status

The USS Omaha encounter remains officially classified as an unexplained UAP event under AARO review. The Department of Defense has never retracted its confirmation of the video's authenticity or asserted that the object was definitively identified.

The case holds enduring historical and scientific importance as one of the few Pentagon-authenticated video recordings displaying transmedium behavior observed by frontline military personnel on calibrated military hardware. It continues to be cited in Congressional hearings and technical discussions regarding maritime domain awareness, airspace security, and the necessity of coordinated sensor networks spanning sky and sea.
