Fishermen off the northeastern coast of Norway may have spotted the first evidence of a renewed Russian program to use marine mammals for military operations, according to widespread media reports on Tuesday. Last week, local fisherman noticed a beluga whale near their boat that seemed to want their attention. As they got closer, they saw a harness strapped to the beluga, outfitted with mounts for GoPro-type cameras. Further inspection revealed “St. Petersburg equipment” embossed on the harness clips.
Norwegian scientists told reporters that they believed the mammal was trained by the Russian Navy. Russian authorities haven’t commented on the speculation, but it’s unlikely the whale was wearing the harness to record his own home videos.
The use of animals for military operations isn’t all that unusual. During the Cold War, the Soviet navy trained dolphins for military use, but the program was discontinued sometime after 1991. The United States Navy has studied marine mammals, including beluga whales, since the 1960s and has trained them to carry out a variety of tasks, like performing recovery operations and finding underwater mines.

Yes, as strange as it may sound, the Navy uses dolphins for a variety of missions. The Naval Information Warfare Center, Pacific, trains Atlantic bottlenose dolphins on a base in Point Loma, Calif., while the Navy’s explosive ordnance disposal community uses the mammals for many of its operations. During the summer of 1998, before my senior year at the Naval Academy, I was temporarily assigned to an explosive ordnance disposal unit at Naval Amphibious Base Coronado that had several marine mammal detachments. One looked for trained enemy divers, another looked for naval mines floating in the water column and another searched for mines lying on the seafloor. Another detachment trained sea lions to help recover expensive items like inert torpedoes off the seafloor so that the Navy could reuse them.
Two big reasons. One, their bio-sonar is better than any mechanical sonar ever made. Dolphins produce sonar waves from their foreheads, and they can quickly locate things that humans cannot. Second, they can repeatedly dive deeper than human divers, reaching underwater depths that we could otherwise reach only using robots. The dolphins “see” enemy frogmen by sensing sound waves bouncing off the hard calcium deposits in human bones, and can sense mines buried by mud and silt on the seafloor by sensing the air void inside the mine’s casing.You have 2 free articles remaining.Subscribe to The Times
How does the Navy do this?
The dolphins live in netted pens suspended from floating docks near the entrance to San Diego Bay. They are fed a tailored diet of herring and mackerel among several kinds of fish daily. Through positive reinforcement with food and affection, each dolphin is trained to identify specific types of target — such as people, moored mines or bottom mines. When it is time to work, a sailor communicates with the dolphin through a combination of whistles and hand signals. The dolphin then kicks its way up and out of the water, sliding onto a wetted mat laid on the dock. Sailors carry the dolphin to a small motorboat that is cut down to the waterline on one side, which allows the handlers to drive to the search area and slide the mammal gently into the water. They then use a device called a transducer that radiates certain sound tones into the water to signal to the dolphin that it is time to search. Once the dolphin has found its target — either human or a mine — it is brought back into the boat, which then swiftly exits the area so that sailors can take over the mission. For enemy frogmen, that can mean tossing concussion grenades into the water. For mines, bomb disposal divers or remotely operated vehicles go into the water to neutralize or destroy them.
Are they ever trained to kill?
No. That’s a common misunderstanding. You can find rumors all over the internet to the contrary about dolphins being strapped with nuclear warheads for suicide missions, but that has never happened. Their mission is simply to find and mark things, and then exit the area as quickly as possible; there are no weaponized dolphins.
