USS Omaha — Trans-Medium UAP Filmed 2019

In July 2019, the guided-missile destroyer USS Omaha was operating approximately 100 miles off San Diego as part of a fleet exercise when its crew detected and filmed multiple unidentified spherical objects operating around the ship. One sequence of particular note captured by the ship's Forward-Looking Infrared (FLIR) system shows a spherical object — designated as a UAP for investigation purposes — approaching the water surface and appearing to enter the ocean. The ship's fire control radar tracked the object to the point of ocean entry. A search and rescue helicopter was dispatched to the entry point; no wreckage, debris, or evidence of an impact was found. The USS Rafael Peralta and other vessels in the area also observed objects during the same period. F/A-18 aircrews from carriers in the area reported similar observations. The footage and associated sensor data were submitted to the Navy's UAP Task Force and later to AARO. The Pentagon confirmed the authenticity of the USS Omaha footage in 2021 during the period of the UAP Task Force's public reporting. The transmedium aspect — a solid object apparently entering the water at speed and submerging without destruction — is considered by researchers and the Pentagon alike as one of the most significant capabilities implied by observed UAP events.
