Underwater UFOs are unidentified objects reportedly seen in the water, entering it, or emerging from it.
Known in English as USOs, underwater UFOs are unidentified objects reportedly seen underwater or on the surface, or entering or emerging from the water. Here, “UFO” refers to an unidentified phenomenon, not a claim that the object is an aircraft or vessel of nonhuman origin.
Reports of such phenomena date back at least to the 1950s. The 1967 Shag Harbour incident in Canada is described in accounts of a glowing object entering the sea, but it does not prove the object came from beyond Earth. Claims made in the media about objects moving at high speed underwater are reports, not verified evidence.
Evidence in underwater cases is considered weaker than evidence from sightings in the air. Visibility underwater is limited, and many reports rely on witness accounts or sonar returns. Possible explanations include natural phenomena, drones, and visual or sonar misidentifications. AARO, the Department of Defense’s All-domain Anomaly Resolution Office, has said it found no verified evidence of extraterrestrial technology.
It is short for an unidentified submerged object or unidentified underwater object.
That is unknown. An object reported as unidentified is not, by itself, evidence of extraterrestrial origin, and there is no verified evidence that these objects are extraterrestrial technology.
In 1967, a glowing object was reportedly seen entering the sea in Canada. The report does not prove that the object was extraterrestrial.
Visibility underwater is limited, and some reports rely on witness accounts or sonar returns, which can be difficult to interpret with certainty.
