It seems that credible USO reports are just as numerous as their airbourne counterparts (if not one in the same) and are also captured,plotted,tracked and correllated on (sometimes multiple) sonar screens.
It also seems they garner just as much covert military interest and enforced/imposed secrecy when sailors and submariners attempt to discuss their experiences.
USO Radar/sonar confirmation documents:
Heres just one account from the Russian military involving professional submariners and USOs taken by Jaques Vallee:
"Many officers were skeptical, but the reports were hard to deny. They were carefully recorded. On October 7, 1977, a submarine repair ship called the Volga was at sea when nine disk-shaped objects circled it. This lasted eighteen minutes. And all the time the radio, the on‑board communications systems, all the electronic equipment went berserk. The commander, Captain Tarantin, ordered his men: 'I want you to observe this carefully and to remember it! I want you to take pictures and to draw it, so that when we return to the Soviet Union no one will be able to say that your captain was drunk or crazy!'"
"Were such reports made public?"
Azhazha shook his head no. "At the time, naturally, they were classified top secret. Now we have a more open attitude in this country. We are able to talk about such things. On a few rare occasions I did publish some UFO information, but I paid for it under Leonid Brezhnev. The official reaction was very harsh, very negative. My career suffered as a result, and the directorship of a scientific group was taken away from me."
Theres also many historical accounts of unknown objects in or emerging from water- people such as Alexander the great,Christopher Columbus,King George V of England,Thor Heyerdahl (Kon-Tiki raft) and medieval Japanese fishermen have all reported such incidents.
This is a good doc which covers some of the sightings (it also seems the nuclear missile carrying warship the Franklin D Roosevelt has had more than its fair share of USO encounters down the years).
