|An unidentified submerged object, or USO,
is any object or optical or mechanical detection phenomenon of unknown
origin observed under water that remains unidentified even after
This particular use of the acronym should not be confused with USO, the
popular abbreviation of the United Services Organization.
The maritime analog to UFOs, or unidentified flying objects,
unidentified submerged objects are often seen by those who study
unidentified flying objects as a related phenomenon (ufologists).
Likewise, many sightings of USOs constituting "typical" UFOs emerging
from the water are seen as a subset of the latter rather than of the
A look at reports of USOs "Unidentified Submerged
Objects", throughout history – from the ancient legends of Atlantis, to
the reports of Christopher Columbus, to modern sightings around Laguna
Cartagena, Puerto Rico (a supposed USO hot bed).
Approximately 71% of the Earth's surface is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 metres (9,800 ft) deep.
Earth is the only known planet with liquid water on its surface and is certainly the only one in our own solar system. However, a layer of liquid water thick enough to decouple the crust from the mantle is thought to be present under the surfaces of the moons Titan, Europa and, with less certainty, Callisto and Ganymede.
A similar magma ocean is thought to be present on Io. Geysers have been found on Saturn's moon Enceladus, though these may not involve bodies of liquid water.
Other icy moons and trans-neptunian objects may also have internal oceans, or have once had internal oceans that have now frozen.
The planets Uranus and Neptune may also possess large oceans of liquid water under their thick atmospheres, though their internal structure is not well understood.
Unidentified Submerged Object Sightings
In May 1958 (17 days), in October 1959 (five days) and
January 1960 (24 days) in Golfo Nuevo (Argentina), an unidentified
submarine was hunted by up to 14 Argentine warships (including an
aircraft carrier) as well as over 30 navy planes.
The submarines, though
audible and occasionally visible to the naked eye, could not be
triangulated by sonar, sonar buoys, hydrophones or radar.
Despite intense bombing and depth-charging by the most up-to-date US
explosives, torpedoes and naval gunfire, it proved impossible to damage
or sink the submarines, and the hunt was abandoned on each occasion
Capt. Ray M Pitts, the leader of the U.S. Navy
anti-submarine warfare team involved in the third hunt, confirmed
afterwards that it had been a definite submarine, but he was prevented
from saying more.
Some sailors and eyewitnesses described it as a Type
XXI U-boat developed by the German Navy 15 years earlier.
In 1966, an Australian banana farmer claimed to witness a USO emerge from a nearby swamp.
In 1967, a fleet of Brazilian ships was followed by a submerged USO for several minutes.
In Sweden in 1999, a supposed USO crashed into a lake, with spectators nearby.
Unidentified submerged objects, also known as USOs, are unknown craft that are sited within our waters. It is believed by some that these craft are extraterrestrial and that they are possibly coming from bases under large bodies of water such as our oceans.
The USO Mystery
strange unknown objects sighted within our waters have been made by
various people around the world. Even some Navy personnel from Russia
have made claims of these objects.
Azhazha, former navy officer and a famous Russian UFO researcher, said
that "Fifty percent of UFO encounters are connected with oceans. Fifteen
more - with lakes. So UFOs tend to stick to the water".
The Bermuda triangle is another area that is thought by some to be a zone that may have UFO activity. Some writers attribute the strange events within the Bermuda triangle to UFOs.
This idea was used by Steven Spielberg for his science fiction film Close Encounters of the Third Kind, which features the lost Flight 19 aircrews as alien abductees.
