According to a maritime analyst, satellite photos show Russia has placed trained dolphins at the entrance to a critical Black Seaport in a move that may be designed to help protect a significant Kremlin naval base there.
The images, provided to The Washington Post by Maxar Technologies, show two dolphin pens at the entrance to Sevastopol harbor in Crimea — which Russian forces annexed from Ukraine in 2014.
H I Sutton, a submarine analyst who first reported on the dolphins for the U.S. Naval Institute on Wednesday, said the pens were moved there in February, around the time of the invasion of Ukraine.
He said the dolphins could be used to counter specialist Ukrainian divers attempting to enter the port to sabotage Russian warships — he also added the United States and Russia have previously trained marine mammals.
