When UFOs are spotted by people on landmasses sightings are typically confirmed by witnesses and radar operators. When you’re at sea however you must be concerned with things below you as well as above you. USOs or Unidentified Submersible Objects are simply UFOs with the ability to travel into, through and out of the water. For those very special sightings the Navy has a group known as a SNOOPIE Team which stands for Ship Nautical or Otherwise Photographic Intelligence Exploitation. This team not only records all data received of the event but required witness verification as well. It is believed that in 2019 a major event of this nature happened and you can find it HERE.
