The Encounter

In July 2019, USS Omaha — a Freedom-class littoral combat ship operating in the Pacific Ocean — tracked multiple unidentified objects on both radar and forward-looking infrared (FLIR) camera systems. The objects were spherical in appearance and were observed maneuvering in a manner inconsistent with conventional aircraft or known drone technology.

The encounter is significant for a reason beyond standard UAP characteristics: in the footage, one of the objects is observed appearing to descend and enter the ocean. If this observation is accurate, it makes the USS Omaha case a potential instance of a "transmedium" phenomenon — an object operating seamlessly across both air and water environments.

Audio captured during the encounter includes ship personnel — including the Combat Information Center team — reacting in real time to the objects' behavior, noting when objects disappear from radar and attempting to coordinate tracking. A submarine was reportedly deployed to search the area where the object entered the water. No recovery was reported publicly.

Context: The 2019 Pacific Naval Encounters

The USS Omaha incident was not isolated. The summer of 2019 saw a series of documented UAP encounters involving multiple U.S. Navy vessels operating off the California coast. Ships including USS Russell, USS Kidd, USS Rafael Peralta, USS John Finn, and USS Omaha all reported encounters with unidentified objects. These encounters were sufficiently widespread and documented that they formed a significant portion of the evidence base that drove the 2021 DNI UAP assessment and the establishment of AARO in 2022.

Declassification and Confirmation

The footage was declassified in 2021. As with the 2004 Nimitz footage, the Pentagon confirmed its authenticity. The objects remain unidentified. The transmedium behavior — if it occurred as observed — would represent a capability with no known parallel in human aerospace or underwater technology.

The USS Omaha case has been cited by researchers and members of Congress as among the most compelling evidence for the need for serious investigation of UAP, precisely because it involves multiple sensor modalities (radar and FLIR), multiple witnesses, and behavior that goes beyond simply appearing in the sky.

Frequently asked questions

In July 2019, personnel aboard USS Omaha tracked multiple unidentified spherical objects on both radar and FLIR camera in the Pacific Ocean. One object appeared to descend into the ocean. The footage was classified and later declassified in 2021, confirmed authentic by the Pentagon.
A transmedium UAP is an unidentified object observed operating across multiple physical environments — transitioning between air and water, for example. The USS Omaha footage appears to document an object entering the ocean, which would represent transmedium behavior. This capability has no known analogue in human technology.
Yes. Multiple U.S. Navy vessels off the California coast in summer 2019 reported encounters with unidentified objects. The pattern was sufficiently widespread that it contributed significantly to the 2021 DNI UAP assessment and the establishment of the Pentagon's AARO office in 2022.
