USS Omaha Underwater Object
On the night of July 15, 2019, according to material later leaked from the littoral combat ship USS Omaha, the ship's radar showed more than a dozen unidentified contacts in a warning area off San Diego, and its infrared camera recorded a round object that appeared to descend into the Pacific and vanish. Leaked in 2021 by filmmaker Jeremy Corbell and confirmed by the Pentagon as authentic Navy-recorded material, the video has never been explained officially. Skeptics read the "splash" as a flare or glare disappearing behind the horizon, and the same weeks saw drones repeatedly fly around other Navy ships in the area; the Navy says the Omaha's own logs for those dates were never retained.
Pictured: USS Omaha (LCS-12), the San Diego-based littoral combat ship whose crew recorded the sensor data at the center of this case, in a U.S. Navy photograph — not a frame of the leaked encounter footage itself. No rights-clear, non-watermarked copy of the actual 2019 CIC video or radar imagery is publicly available for reproduction here; the leaked material remains circulated only through Jeremy Corbell's own releases and the news outlets that licensed clips from him.
Theoretical Alignment
The USS Omaha case is most commonly framed under the Extraterrestrial Hypothesis by advocates because of its instrumented "transmedium" signature — an object apparently transitioning between air and water with no visible means of propulsion — but the framework that actually carries the most explanatory weight given the full public record is a terrestrial one: the Advanced Adversary/Domestic Drone Hypothesis, which treats the July 2019 encounters as a probable, still-unattributed unmanned aerial or maritime intelligence-collection operation exploiting a Navy sensor and procedural blind spot. The Psycho-Social framework carries only marginal weight here — the CIC crew were trained radar and thermal-imagery operators cross-referencing two independent onboard sensor systems in real time, not a single overwrought observer — while the Interdimensional Hypothesis finds essentially nothing case-specific to anchor it.
Background
By the summer of 2019, the U.S. Navy was already shifting how it handled reports of unidentified aircraft near its ships and aircraft. The catalyst had been encounters involving Nimitz Carrier Strike Group pilots off Southern California in 2004 and USS Theodore Roosevelt aviators off the East Coast in 2014–2015, which became public through leaked cockpit video and New York Times reporting in December 2017. In April 2019 Politico reported that the Navy was drafting new guidelines for pilots and other personnel to report unidentified aircraft entering training ranges. That new reporting culture was only a few months old when the USS Omaha, an Independence-class littoral combat ship homeported in San Diego, was operating off Southern California in mid-July 2019.
The Omaha did not encounter its sphere in isolation. Beginning on the night of July 14, 2019, and continuing intermittently through the end of the month, several Navy ships operating off Southern California — deck logs and briefings obtained by The War Zone name USS Kidd, USS Rafael Peralta, USS Russell, USS John Finn and USS Paul Hamilton among them — logged encounters with small aerial objects their own records call "UAS," "UAV" or drones, some lingering around the ships for well over 90 minutes, often at night and in low visibility. Navy documents later released to The War Zone include briefing slides, deck logs, emails and photographs taken by "SNOOPIE" visual-documentation teams; NBC News reported that the FBI was involved. This site covers that wave in its own 2019 Navy Destroyer Drone Swarm case file.
The Omaha incident did not become public knowledge until nearly two years later. Reporting on the destroyer encounters surfaced first, in a series of pieces beginning in March 2021 by The War Zone's Adam Kehoe and Marc Cecotti built from FOIA'd ship logs and Navy correspondence. The Omaha's own imagery reached the public through documentary filmmaker Jeremy Corbell, working with journalist George Knapp of KLAS-TV in Las Vegas, who published material attributed to the Omaha in April 2021 and the infrared clip, a video of a radar screen and onboard audio in May 2021 — weeks before the Office of the Director of National Intelligence's congressionally mandated Preliminary Assessment on UAP was due.

The July 2019 Swarm: A Wider Pattern
To understand what happened aboard the Omaha on the night of July 15, it helps to see it as one data point inside a documented, multi-ship pattern. Beginning the previous evening, July 14, 2019, Navy deck logs obtained by The War Zone record small aircraft around several ships, with entries such as "Two UAV's spotted off the starboard wing" and a light hovering over a destroyer's flight deck. Logs and AIS data analysed by The War Zone show the drones staying aloft for well over 90 minutes, longer than typical commercial quadcopters. Ships sent "SNOOPIE" teams to photograph them, and at least one ship stopped broadcasting on AIS before an encounter.
The encounters were not confined to military observers. When Navy ships asked the cruise ship Carnival Imagination whether the drones were its own, its crew said they were not, and that they could see five or six of them flying around the destroyers. It was within this same period, in the same waters, that the Omaha's crew recorded their own unknown contacts.
The pattern continued sporadically through the end of the month. A Navy briefing slide released under FOIA gives a timeline of USS Paul Hamilton's interactions with objects labeled "UAS," beginning at 7:56 p.m. local on July 16, and is one of the first official documents to use the word "swarm"; on July 30 the same ship reported drones within about 200 yards of its bow. Then-Chief of Naval Operations Admiral Michael Gilday told reporters in April 2021 that the Navy had not identified the drones ("No, we have not"), adding that he had "no indications at all" that they were extraterrestrial. Navy documents released to The War Zone in June 2022 show that the service did have "significant information about the potential origin of the drones": one draft assessment linked some sightings to a Hong Kong-flagged bulk carrier, the Bass Strait, and a July 21 report attributed others to "local fisherman operating personal quadcopters," although the operators of the most serious incidents remained unknown. In May 2022 Deputy Director of Naval Intelligence Scott Bray told Congress the Navy was "reasonably confident" that a related 2019 night-vision video of triangular lights showed drones.
What the Navy's Released Records Show
Most of what is firmly known about the July 2019 drone activity comes from Navy records released under FOIA and published by The War Zone's Adam Kehoe and Marc Cecotti in 2022. The most detailed is a one-page "UAP Brief" slide giving a timeline for USS Paul Hamilton. It begins at about 7:56 p.m. local on July 16, ten minutes after the destroyer stopped broadcasting on AIS, with one UAS spotted about a nautical mile away. About twenty minutes later two were seen, and one fell into the water. At 8:26 p.m. the bridge saw several, with flashing red lights; at 8:50 p.m. the slide notes a "UAS swarm"; at 9:11 p.m. one object passed directly overhead at about 2,000 feet before the group turned away at around 60 knots. The episode ended at 10:39 p.m., 2 hours and 49 minutes after it began. The only image released with the slide is a low-resolution infrared frame showing three blurry dots.
Other records describe the same pattern. USS John Finn's deck log for the evening of July 14 notes a possible UAS with red flashing lights crossing the ship at about 1,000 feet. USS Russell first reported three unknown UAS on July 17, about 62 nautical miles southwest of San Nicolas Island. Briefing material from the cruiser USS Bunker Hill noted as many as 11 drones nearby and valid radar tracks up to 21,000 feet, and USS Ralph Johnson's draft public-affairs statement described the drones' "safe and professional approach." Around July 30, Paul Hamilton reported drones coming as close as 200 yards to its bow. The same documents show the Navy had "significant information about the potential origin of the drones": a draft assessment that the Hong Kong-flagged bulk carrier Bass Strait was "likely conducting surveillance on Navy vessels using drones" (a June 2022 update noted that dark dots in the photographs may be part of the ship's structure), and a July 21 Paul Hamilton report assessing one group as "local fisherman operating personal quadcopters." None of these records mentions the Omaha or a sphere.
Following the Wiggins Thread
Because Senior Chief Alexandro Wiggins is the only named sailor who has spoken publicly about UAP encounters on an Independence-class ship off Southern California, some coverage has folded him into the Omaha story. The record is narrower. His September 9, 2025 testimony and his interviews concern February 15, 2023, aboard USS Jackson, when he says he tracked a "Tic Tac"-shaped object that joined three others; he told the committee he believed one had risen from the sea but had no visual proof of it. In the hearing he said that on a littoral combat ship "the CIC is on the bridge, so it is called ICC-1," and, asked what he now thought the objects were, "I want to be as skeptical as everyone else." The single link to the Omaha is a sentence in a 2025 Interesting Engineering article that he "previously served aboard the USS Omaha, one of ten Navy warships" reported swarmed in 2019. Whether he was aboard in July 2019, and what if anything he saw, has not been reported. Interesting Engineering describes him as a radar expert with 23 years of service; at the hearing he introduced himself as an active-duty operations specialist and senior chief petty officer, and told the committee he had believed in UFOs before his encounter: "I am from Las Vegas, and I have watched George Knapp my whole life."
Night of the Encounter: Radar, Thermal, and a Splash
The Omaha's own encounter is known almost entirely from Jeremy Corbell's releases and descriptions. He said the footage was filmed in the ship's Combat Information Center on July 15, 2019, "in a warning area off San Diego @ 11pm," by a "VIPER" (visual intelligence) team. According to Corbell, the ship's radar showed as many as fourteen unknown contacts around it at one time, at speeds of 40 to 138 knots (46 to 158 mph). That speed range is well within the performance of small unmanned aircraft and nowhere near the performance claimed in cases such as the 2004 Nimitz encounter, so whatever the Omaha sphere was, nothing in the speed data requires exotic propulsion. Metabunk participants noted that the radar's displayed speed figures are relative to the ship and that the set is optimized for surface and low-altitude targets.
The infrared clip that became the case's public signature shows a dark round shape (the camera was in "black hot" mode, according to Mick West) moving over the water, then descending to the surface and disappearing. Onboard audio captured crew reactions, including "Whoa, it splashed!" Corbell has described the night as a UAP event series that ended with one of the unknown targets entering the water — his own characterization, not an official Navy one. He also wrote that "a submarine was used in the search and recovered nothing"; no Navy source has confirmed that a search took place.
The Sphere's Size and the Limits of the Video
The size estimate for the object — about six feet, or two meters, in diameter — comes from Corbell; no method or official source for it has been published. Skeptical analyst Mick West of Metabunk has argued that the clip does not show a splash at all. He first suggested a balloon with a suspended payload, then "flipped" to a flare or other heat source made to look larger by glare, and said the way the object fades out over several frames "suggests to me that it's a glare, going behind the horizon (or maybe just a wave)." He also pointed out that apparent sharp movements early in the clip come from the camera moving, not the object. All publicly circulated copies of the footage are re-recorded or re-encoded copies released through Corbell, not a raw file released by the Navy.
The Leak: Corbell, Knapp, and the Pentagon's Careful Confirmation
The Omaha's sensor data remained entirely outside the public record for nearly two years. That changed in April 2021, when Jeremy Corbell — a documentary filmmaker previously best known for Bob Lazar: Area 51 & Flying Saucers — began publishing still images he attributed to the Navy, working in partnership with George Knapp, the longtime KLAS-TV Las Vegas investigative reporter who had broken the Bob Lazar story in 1989. In mid-May 2021, Corbell and Knapp published the fuller Omaha material: the infrared video itself, a video of the radar display, and onboard audio, weeks ahead of the Office of the Director of National Intelligence's congressionally mandated UAP report.
The Pentagon's response, when it came, was narrower than most press coverage of it suggested. Department of Defense spokesperson Susan Gough told reporters: "I can confirm that the video was taken by Navy personnel, and that the UAPTF included it in their ongoing examinations." That is a real, on-record confirmation of two specific facts — that the footage is genuine, Navy-originated material, and that it was formally under review by the Unidentified Aerial Phenomena Task Force — but Gough pointedly declined to go further, offering no comment on whether the object had been identified, whether it was classified as a genuine "unknown," or what conclusions, if any, the UAPTF's examination had reached. Numerous headlines at the time compressed "the video is authentic Navy footage" into "the UFO is confirmed real and unexplained," a distinction this case file treats as important: Gough confirmed provenance, not anomalousness.
The "VIPER Team" and "Combat Information Center" Questions
A close read of Corbell's framing raised two terminology questions on the Metabunk forum. Participants noted that Independence-class littoral combat ships do not have a conventional "Combat Information Center" but an integrated command center on the bridge, and asked whether "CIC" was being used loosely. That question has since been answered in part by an Independence-class sailor: at the September 2025 House hearing, Senior Chief Alexandro Wiggins, describing his 2023 encounter on USS Jackson, said that "on a Littoral Combat Ship (LCS), the CIC is on the bridge, so it is called ICC-1, but yes, same." The same Metabunk researchers flagged, as an oddity rather than evidence, a December 2019 short story published in the Center for International Maritime Security's "Fiction Week" that featured a fictional USS Omaha and "Viper" aircraft. Neither point disproves the case; both are reasons to treat the precise wording of Corbell's descriptions with care.
The Missing Deck Logs
The most consequential post-leak development in this case is not a new claim about the object but a gap in the Navy's own records. On April 21, 2021, FOIA researcher John Greenewald Jr. of The Black Vault asked the Navy for all records of an incident on July 15, 2019 in which USS Omaha "encountered and observed a 'possible 'UAS', spherical in shape, moving towards the surface of the water and then disappearing," and for the ship's deck logs for July 13–18, 2019. The Navy's answer, dated September 15, 2021 and signed for Commander, Naval Surface Force, U.S. Pacific Fleet, explained that "for this class of ship, while underway, deck logs are digital voice recordings," periodically written to optical media and shipped to the Naval History and Heritage Command. The ship searched digital copies, discs and paper "and concluded that the prior crew did not retain or create records for July 1 – 18, 2019." NHHC and the Federal Records Center had nothing for those dates either. "The loss of these records indicates their system for record retention requires further attention," the letter said; NHHC did find and release deck logs for July 19–31, 2019.
This matters directly for how much weight the case can bear. The missing logs cover the whole first half of July, not just the night of the encounter, and the Navy's letter attributes the gap to poor record retention rather than withholding. That is a mundane explanation, and an official one. But it still means that deck logs and voice recordings, the kind of contemporaneous documentation that would let outside researchers check the leaked video and radar footage against the ship's own record of the same hours, do not exist for this case. Everything the public has seen has come through one investigative team's leaked release.
The Navy's letter is not the only account of the gap. In February 2022 The War Zone, reporting on the Paul Hamilton slide, said the Omaha had not submitted deck logs for the period and that its voyage management system records were beyond their retention period, and that no explanation had been given for why the logs were never created. The Navy's own wording — that the prior crew "did not retain or create" the records — leaves open which of the two happened. Either way, the gap runs from July 1 to July 18 and so covers more than two weeks of routine operations, not only the night of the sphere, which argues against a targeted removal of the encounter.
A Related Leak That Was Explained
One other leaked video from the same month offers a useful comparison. In April 2021 Corbell released night-vision video, attributed to USS Russell, showing triangular or "pyramid"-shaped lights over the ship. At a House Intelligence subcommittee hearing in May 2022, Deputy Director of Naval Intelligence Scott Bray said the Navy was now "reasonably confident" the lights were drones. The footage had been "unresolved for several years," he said, until the Navy compared it with night-vision imagery and other data from a later drone swarm "off a different coast"; the triangular shape came from the night-vision scope's aperture, not the objects. That case shows how an apparently exotic Navy image from July 2019 can be resolved once comparison data exist. No comparable resolution has been published for the Omaha sphere.
Congressional and Official Follow-Up
The Omaha case fed into the broader wave of institutional UAP attention that followed the 2021 leaks. The ODNI's June 25, 2021 "Preliminary Assessment: Unidentified Aerial Phenomena" catalogued 144 reports collected by the UAPTF between 2004 and 2021, without naming the Omaha case. The report sorted UAP into five possible explanatory categories (airborne clutter, natural atmospheric phenomena, U.S. government or industry programs, foreign adversary systems, and "other") and had no "transmedium" category; that term entered official usage later, in AARO's mandate. When the Department of Defense stood up the All-domain Anomaly Resolution Office (AARO) in July 2022, it took over the UAP Task Force's caseload; AARO has not published an assessment of the Omaha video. AARO's subsequent public reporting — its 2024 Historical Record Report and later releases — has consistently found "no empirical evidence" that any case in its inventory represents extraterrestrial technology, while also acknowledging that a meaningful fraction of reports, including some instrumented ones, remain formally unresolved rather than positively explained. The Omaha sphere has been neither confirmed as anomalous by any government body nor publicly closed out with a named conventional explanation.
The same waters came up again in the official record in 2025. On September 9, 2025, the House Oversight Committee's Task Force on the Declassification of Federal Secrets held a hearing at which Alexandro Wiggins, an active-duty Navy operations specialist and senior chief petty officer, testified about a separate encounter on February 15, 2023 aboard USS Jackson off Southern California, in which he and other watchstanders tracked a "Tic Tac"-shaped object joining three others. He said he believed one had risen from the sea but acknowledged he had no visual proof of that. That 2023 event is a distinct case and not part of this case file. Interesting Engineering reported that Wiggins "previously served aboard the USS Omaha, one of ten Navy warships" reported swarmed in 2019, but neither that article nor his testimony says he was aboard during the July 2019 encounter or saw the sphere, and the hearing transcript does not mention the Omaha. His policy requests to Congress — standardizing sensor configurations across ship classes and protecting sailors who report — bear on two of this case's weaknesses: loosely labeled sensors and teams, and a public record that arrived through a leak rather than a formal reporting channel.
Key Witnesses
Alexandro Wiggins (former Omaha crew member; not a confirmed witness)
Wiggins is listed here because some coverage has presented him as an Omaha witness, which the record does not support. Interesting Engineering reported in 2025 that he "previously served aboard the USS Omaha," but no source consulted says he was aboard on July 15, 2019 or saw the sphere, and he did not mention the Omaha in his September 2025 congressional testimony, which concerned a 2023 encounter aboard USS Jackson. Earlier versions of this page said he had "confirmed his earlier role in the Omaha's 'swarm' period" and was "skeptical" of his own Omaha observations; neither statement was found. His "skeptical" remark was made at the 2025 hearing about the 2023 Jackson object ("I want to be as skeptical as everyone else"), and his statement that he is not a whistleblower also came in the context of the Jackson encounter.
Unnamed USS Omaha CIC Watch Team
All of the direct testimony in this case comes from Omaha personnel who remain unidentified. Their radar display, infrared footage and audio reactions are the case's entire primary evidence, but they have reached the public only through Jeremy Corbell's framing of leaked material, not through on-record Navy-authorized statements or sworn testimony. That limits how far specific claims (the "VIPER team" designation, the object count, the size estimate, the submarine search) can be checked.
Jeremy Corbell & George Knapp
Neither Corbell nor Knapp witnessed the July 2019 encounter; both function here as the conduit through which leaked Navy material and secondhand crew accounts reached the public in 2021. Knapp brings decades of consistent, professionally credentialed UAP reporting (including facilitating the 2017 New York Times AATIP story) that lends institutional weight to the material's authenticity; Corbell brings a track record of securing genuine leaked government material but also a consistent editorial preference for extraterrestrial framing in how he presents it, which this case file treats as a reason for independent verification of his specific claims (object counts, size estimates, the submarine search) wherever possible, rather than as a reason to distrust the underlying leaked footage itself.
Susan Gough
Gough's on-record May 2021 statement is the only point in this case's timeline where an accountable U.S. government official formally confirmed any specific fact about the leaked material — that it was "taken by Navy personnel" and under UAPTF review. Her statement is deliberately narrow and should not be over-read as government confirmation that the object itself was anomalous.
The Five Observables Assessment
The Five Observables framework is applied to the performance characteristics reported in this case:
Assessment: The USS Omaha case is unusual within the Five Observables framework for how narrowly it fits: the reported radar speeds (roughly 46–158 mph / 40–138 knots) fall well short of hypersonic performance and show no indication of the instantaneous, inertia-defying acceleration reported in cases like the Nimitz Tic Tac encounter, and no credible claim of anti-gravity lift has been made by any witness or investigator in this case. Low observability is speculative at best — the object was tracked on conventional radar and thermal imaging without apparent difficulty, though its lack of visible wings, control surfaces, or an identifiable propulsion signature keeps this observable from being ruled out entirely. The case's real distinguishing feature is the reported trans-medium transition itself: an object apparently moving from air to water, with no wreckage recovered by a submarine search that Corbell reports but the Navy has not confirmed. That observable is marked "Present (Reported)" rather than simply "Present" because it rests entirely on the crew's real-time visual/thermal interpretation of the object's disappearance at the waterline, with no acoustic, sonar, or physical confirmation that it actually entered the water at all rather than, for instance, passing below the thermal camera's effective detection threshold near the horizon.
Evidence Assessment
Supporting Anomalous Origin
- According to Corbell, radar and infrared imaging — two onboard sensors — both showed unidentified contacts, though only the infrared clip shows the sphere itself
- Pentagon spokesperson Susan Gough issued an on-record confirmation that the footage was genuine, Navy-recorded material formally under review by the UAP Task Force.
- The footage is genuine Navy material, and its audio captures the crew's own real-time reactions
- The encounter occurred within a broader, documented multi-ship wave of drone sightings that the Chief of Naval Operations said in April 2021 had not been identified
- Corbell reports that a submarine search found no wreckage, which advocates read as consistent with a craft that left the area underwater (the search itself is unconfirmed)
Supporting Conventional Explanation
- Radar-derived speeds (46–158 mph) are entirely within the performance envelope of small unmanned aircraft and show none of the extreme acceleration or hypersonic performance reported in other high-profile Navy UAP cases.
- USS Omaha's deck logs and voice recordings for July 1–18, 2019 were never retained, by the Navy's own account, so the leaked footage cannot be checked against any official contemporaneous record
- The public record comes almost entirely through one advocacy-oriented source (Jeremy Corbell); specific claims — the "VIPER team" designation, the object count, the size and the submarine search — have not been confirmed by the Navy
- A documented rival hypothesis exists: the same weeks saw repeated drone flights around Navy ships in the area, which Navy documents attribute in part to a commercial ship and local fishermen's quadcopters, and which the Navy has treated as drones, not unknowns
- Mick West has argued that the clip shows a balloon or, more likely, a flare or other heat source fading behind the horizon or a wave, rather than a splash; no second sensor platform has been released to test this
Why "Open"
This case is rated Open because neither reading is settled on the public record. The footage is genuine Navy video, and nobody has published an identification of the object. Against that, almost everything known about the encounter comes from one advocacy-oriented source; the ship's own logs for the period were never retained; the "splash" is visible only on a low-quality infrared clip that a skeptical analyst reads as a flare or glare disappearing behind the horizon; and the same weeks saw drone activity around nearby Navy ships that Navy documents attribute partly to identifiable civilian and commercial sources. The leading explanations are terrestrial, but none has been confirmed for this specific object.
Sensor & Instrumentation Detection Profile
The case rests on two onboard sensors as described by Corbell: the ship's radar, whose display reportedly showed as many as fourteen unknown contacts at once at 40–138 knots, and an infrared camera used to look at radar contacts, which Metabunk participants identified from the released material as a SAFIRE-type FLIR turret. The infrared clip shows a round object, estimated by Corbell at about six feet across, moving over the water before appearing to descend and disappear at the surface. No independent second platform — another ship's radar, an aircraft, a satellite pass or a sonar record — has been publicly released to cross-check either the radar footage or the infrared clip, which is the largest instrumentation gap in the case.
Environmental & Geospatial Context
The encounter occurred over open ocean in "a warning area off San Diego," in Corbell's words, presumably W-291, the offshore military warning area off Southern California whose scheduling is managed by the Fleet Area Control and Surveillance Facility (FACSFAC) San Diego. The ship's exact position has not been released. At 11 p.m. PDT on July 15, 2019 the Moon was 99.6% lit, one day before full, and about 30° up in the south-southeast (JPL Horizons), so the sea was moonlit. No weather record for the night has been released. The 2004 Nimitz encounters took place in the same general Southern California offshore operating area.
Observer Credibility & Occupational Profile
The primary observers were active-duty Navy watchstanders — by Corbell's account radar operators and a designated "VIPER" visual-identification team — whose job is to distinguish real contacts from clutter and known traffic. None has been publicly identified as a witness. An earlier version of this page named Senior Chief Alexandro Wiggins as one of the Omaha watch team; no source supports that. Their testimony is known only through Corbell and Knapp's framing of leaked material and audio rather than through on-record interviews or sworn statements. Professional operators watching their own screens is a strong observer profile in the abstract, but the public record here is mediated almost entirely through one advocacy-oriented broadcaster.
Physical & Material Assays
No physical evidence exists in this case. Corbell says a Navy submarine searched the area and found nothing; the Navy has not confirmed this. There is accordingly nothing to submit for metallurgical, isotopic, or any other laboratory analysis — the entire evidentiary record consists of sensor data (radar plot and infrared video), audio, and testimony. This absence is itself informative: it means the "transmedium" characterization of the object rests entirely on the visual appearance of the infrared clip and the CIC crew's real-time interpretation of it, with no corroborating acoustic, sonar, or recovered-material evidence to independently establish that anything actually entered the water rather than, for example, passing below the sensor's effective detection envelope or the visible horizon.
Historical Precedents & Archive Matches
The USS Omaha case belongs to a well-established sub-genre of "unidentified submerged object" (USO) reports with precedents going back decades — including the 1967 Shag Harbour incident off Nova Scotia and numerous Cold War-era reports of unexplained sonar contacts and high-speed underwater objects tracked by U.S. and Soviet naval forces — but it is unusual within that genre for being instrumented by a modern multi-sensor military platform rather than relying on unaided visual testimony. Within this site's own catalog, its closest archive match is the November 2004 USS Nimitz/"Tic Tac" encounter, which occurred in the same general offshore Southern California training complex and was likewise first instrumented on shipboard radar (aboard the USS Princeton) before being visually confirmed — though Nimitz differed in being confirmed by an independent airborne platform (Commander David Fravor's F/A-18) rather than resting on a single ship's own sensors. The case also sits inside a broader, better-documented archival record: Navy message traffic and ship logs published via FOIA and reporting by The War Zone confirm that at least five other Navy surface combatants — USS Kidd, USS Rafael Peralta, USS Russell, USS John Finn, and USS Paul Hamilton — independently logged unidentified aerial contacts in the same W-291 warning area across multiple nights in July 2019, a genuinely corroborated multi-platform wave that is separate from, but contextually inseparable from, the Omaha's own sphere sighting.
Material Analysis
There is no physical or trace material evidence in this case, and none has ever been claimed by any party. Corbell says a submarine searched the last-tracked position and found nothing; no official source confirms that search, and the ship's exact position has never been released. That absence cuts in more than one direction at once: it is cited by some as consistent with a craft capable of genuinely operating underwater and simply departing the area rather than crashing, while skeptics note it is equally consistent with a small consumer or commercial-grade drone that either was recovered by whoever operated it, sank and disintegrated in salt water beyond practical recovery, or was never physically at that exact position to begin with because the sensor read was itself the limit of what was actually tracked. No isotopic, metallurgical, or any other laboratory assay exists for this case because no material was ever recovered to test.
Supporting Non-Terrestrial Origin
- A submarine search, as reported by Corbell, recovered nothing
- No known consumer, commercial, or publicly documented adversary drone platform of 2019 is established to be routinely water-submersible in the specific manner described — a controlled, unhurried descent into the ocean rather than a crash.
Supporting Terrestrial Origin
- A small object striking open ocean water at night, in a search area spanning many square miles with imprecise position data, is a genuinely difficult search-and-recovery problem even for a fully conventional downed drone — non-recovery alone does not distinguish between exotic and mundane origins.
- Some purpose-built maritime surveillance drones and sonobuoy-adjacent naval platforms are specifically designed to be recoverable, disposable, or self-scuttling, which would also produce a "no wreckage found" result for an entirely mundane object.
The Conventional Explanation Candidate: Coordinated Small Unmanned Aircraft (Possible Adversary ISR Platform)
The single strongest conventional candidate is that the Omaha sphere, and the broader July 2019 wave it belongs to, involved coordinated small unmanned aircraft — potentially an adversarial or unauthorized commercial intelligence-collection operation testing Navy sensor coverage, reporting procedures, and electronic emissions near an active training range. This candidate is taken seriously by the Navy itself: the drone incidents drew in the FBI, according to NBC News, and The War Zone's analysis of the logs and AIS data found the drones aloft for well over 90 minutes, longer than typical commercial units. Navy documents later released under FOIA attribute some of the July 2019 drone sightings to a commercial cargo ship and others to "local fisherman operating personal quadcopters." The reported radar speeds for the Omaha's contacts (46–158 mph) sit comfortably within small-UAS performance, and a small consumer or commercial drone descending onto calm water at night could plausibly present, on a compressed and low-resolution infrared feed, as a compact self-illuminated sphere slowing and disappearing at the surface. What keeps this from being a resolved explanation is that the Chief of Naval Operations said in April 2021 that the drones had not been identified, the operators of the most serious incidents remained unknown in the Navy's own documents, and nothing links a specific drone to the Omaha's infrared object.
Balloon, Flare or Glare Behind the Horizon
Skeptical analyst Mick West has argued that the clip does not show a splash. His first guess was a weather or scientific balloon with a suspended payload, which would bob on hitting the water; he later "flipped" to a flare or other heat source made to look larger by glare, noting that the object's fade-out over several frames "suggests to me that it's a glare, going behind the horizon (or maybe just a wave)," and that its early jerky motion comes from the camera. This explanation addresses the most striking element of the case, the apparent water entry. It does not explain the radar contacts that Corbell describes, which may well be the same drones reported by other ships.
Deliberate Navy or Allied Test/Exercise Asset
A third possibility is that some or all of the July 2019 contacts were an unacknowledged U.S. military or allied test platform — a classified drone program, a contractor demonstration asset, or an exercise-related decoy — operating in the area without the ships' crews being briefed on it, consistent with well-documented historical patterns of classified programs producing genuine "unknowns" for personnel without a need-to-know. No evidence has emerged of an undisclosed friendly program matching the description. This candidate remains a plausible but currently unconfirmed possibility rather than a demonstrated one.
Coordinated Small UAS / Possible Adversary ISR
Highly PlausibleConsistent with the reported speeds, coordinated multi-object behavior, extended endurance, and the FBI involvement reported by NBC News; Navy documents attribute some of the month's drone sightings to a commercial ship and local fishermen — but never confirmed with a named platform, operator, or launch point.
Balloon, Flare or Glare Behind the Horizon
InconclusiveDirectly addresses the apparent water entry, and fits the clip's fade-out and camera motion, but cannot be tested without the original footage and the ship's position.
Undisclosed Friendly Test/Exercise Asset
InconclusiveHistorically plausible in general terms, but with no positive evidence for or against it.

Corrections (October 2026)
A fact-check against the Navy's September 2021 FOIA response, the September 2025 hearing transcript and the reporting it relied on found that the earlier version of this page presented Senior Chief Alexandro Wiggins as a member of the Omaha's July 2019 watch team who had "confirmed his earlier role" and said he was "skeptical" of his own Omaha observations. The only source found, a 2025 Interesting Engineering article, says he "previously served aboard the USS Omaha"; nothing places him aboard on July 15, 2019, his testimony concerned a 2023 encounter aboard USS Jackson, and his "skeptical" remark and his denial of being a whistleblower were about that later event. The page also said no Navy statement had explained the missing deck logs; the Navy's FOIA letter states that the prior crew "did not retain or create records for July 1 – 18, 2019" and that "their system for record retention requires further attention."
Following this review, the rating was changed from Open 51 to Open 40 (October 27, 2026), because the higher rating had rested partly on claims corrected or removed above.
Other corrections: the ODNI's 2021 Preliminary Assessment has no "transmedium" category; AARO was established in July 2022, not September; the March 2019 "formal" Navy guidance update is not documented (Politico reported in April 2019 that guidelines were being drafted); the Moon was 99.6% lit, one day before full, not ~95% and "three days" from full (JPL Horizons); FACSFAC San Diego manages the offshore warning areas and is not a "drone-testing facility"; Mick West argued for a balloon and then a flare or glare going behind the horizon, not a distant aircraft or compression artifact. Attributed to Corbell rather than stated as fact: the fourteen radar contacts and their speeds, the six-foot size, the "VIPER team" and the submarine search. Removed as unverified: the 113,000-square-nautical-mile size and 600-nautical-mile extent of W-291, the precise map coordinates as a reported position, several unsourced destroyer-log quotations and times, Third Fleet and NCIS involvement, and computed airport and reanalysis-weather fields. Added: Navy documents released in 2022 attributing some of the month's drone sightings to a commercial ship and local fishermen.
