Unidentified Submerged Objects: From Navy Classifications to Maritime Folklore and Paranormal Inquiry

USOs are unidentified underwater entities that the U.S. Navy classifies as sea creatures like whales or sharks when they interfere with ships or sonar, while ufologists such as Tim Gallaudet use the term for water-traveling unidentified objects, and researchers like Scot Christenson and Collin Woodard discuss their potential threats to naval operations and call for renewed attention, highlighting how the topic sits at the boundary of maritime folklore and paranormal inquiry with unclear truth and frequency.
