Unidentified Submerged Objects
Unidentified Submerged Objects or USOs are any objects or optical phenomenon seen in the water which are of unknown origin and cannot be identified even after being thoroughly investigated.
These Unidentified Submerged Objects are seen by most ufologists and investigators as a phenomenon the same as or similar to UFOs, Unidentified Flying Objects, the difference being they are seen traveling under or entering or leaving a body of water.
Most USO sightings are of a "typical" UFO emerging from the water, and are not seen or classified as a separate phenomenon by most people. Although identifying and dispelling unidentified flying objects has typically been important to militaries as a national security, the relatively rare USO sightings, compared to UFO sightings have never been reported as a national threat or caused the sensation that typical UFO sightings often have.
Ranging is size and shape the most common USO sightings are of disk shapped or cylindrical shapped objects. Traveling at speeds far exceeding any earth based underwater craft these objects typically travel anywhere between 150 and 500 knots when submerged. Some of these objects have even been reported as traveling at much higher speeds.
The most famous USO sighting was in 1967 at
Shag Harbour, Canada.
