In March 2026, Congressional representatives formally requested 46 specific videos documenting unidentified aerial and submerged phenomena, including footage from Navy submarine operations. Among these requests are recordings of unidentified submerged objects (USOs)—phenomena operating underwater or transitioning between air and water environments—captured during classified fleet operations between 2019 and 2022.
The March 25, 2022 Incident
The most documented submarine encounter occurred on March 25, 2022, when multiple spherical objects were recorded diving in and out of water near a highly classified submarine position. The incident involved objects displaying transmedium capability—the ability to operate across both air and water environments seamlessly. Multiple spheres were observed transitioning between mediums, a characteristic not associated with known underwater or aerial vehicle designs.
Transmedium Capability and AATIP Framework
The transmedium characteristic represents one of five observable traits formally documented by the Navy’s Advanced Aerospace Threat Identification Program (AATIP). The other four characteristics include hypersonic velocity, low observability, instantaneous acceleration, and positive lift with no apparent propulsion. The March 2022 incident specifically demonstrated the transmedium capability, with objects moving fluidly between water and air without apparent propulsion mechanisms or structural modification.
Fleet-Wide Documentation
Congressional documentation reveals that both Atlantic and Pacific fleet operations recorded similar encounters during this period. Encounters were documented across multiple fleet commands during this period. The specificity of Luna’s request for submarine-recorded footage indicates these incidents remain among the most credible documented evidence of USO activity.
Congressional Accountability
The formal Congressional demand for these 46 videos reflects growing pressure for transparency regarding non-human intelligence activities documented by military assets. Submarine-recorded footage carries particular significance due to the advanced sensor systems deployed on classified vessels and the controlled environment of underwater observation.
The March 2026 Congressional request explicitly names submarine-recorded footage as a distinct category of evidence, underscoring the documented nature of these encounters and their relevance to ongoing UAP/USO investigation and policy discussions.
