Unidentified submerged objects are objects or phenomena detected in water that have not been identified.
USO refers to an object or phenomenon detected in water that has not been identified. The term is the maritime counterpart to UFO and is sometimes used for phenomena seen underwater or emerging from the sea. Some reports describe objects entering the water, moving through it, or coming back out without an immediate explanation. UFOs are the standard comparison for phenomena seen in the sky.
According to some sources, military and civilian reports of such phenomena date back at least to the 1950s. Media coverage and commentary have linked them to claims of extreme speeds or unusual behavior, but those remain claims, not verified conclusions.
The evidence available to the public remains inconclusive. The U.S. Department of Defense has said that reports of unidentified anomalous phenomena do not necessarily indicate extraterrestrial activity, and that many have ordinary explanations. Discussions of underwater detection have also cited underwater hazards and marine animals as possible explanations or concerns.
