As their name implies, unidentified submarine objects (USOs) are objects seen beneath the sea that defy identification. In some cases a USO is suspected of being some kind of sea monster—an unknown beast inhabiting deep waters. In others, the USO is thought to be an experimental submarine of some sort because, according to witnesses, it emerged from the water to fly away. In several of these cases, the USOs do not appear to be solid objects but are balls of light. Consequently, some people have suggested that such USOs are either extraterrestrial spacecraft or proof that unknown civilizations with advanced technology, such as Atlantis, exist within the world’s oceans.
