The US Naval Institute has a closer look at what is believed to be an explosive Uncrewed Surface Vessel (USV) of Ukranian origin, found in Crimea.

According to the report, the propulsion appears to have been from a Sea-Doo personal recreational watercraft.

The report includes a comparison with past examples of explosive motor boat and significantly, the diagram of the suspected Ukrainian craft is along side an outline of an adult male, providing scale, that suggests the craft is about 12 feet in length.

Hopefully the Coast Guard is paying attention, because similar craft might be employed by terrorist against the US.
