Fishermen off the northeastern coast of Norway could have noticed the primary proof of a renewed Russian program to make use of marine mammals for navy operations, in keeping with widespread media stories on Tuesday. Final week, native fisherman observed a beluga whale close to their boat that appeared to need their consideration. As they bought nearer, they noticed a harness strapped to the beluga, outfitted with mounts for GoPro-type cameras. Additional inspection revealed “St. Petersburg gear” embossed on the harness clips.
Norwegian scientists advised reporters that they believed the mammal was skilled by the Russian Navy. Russian authorities haven’t commented on the hypothesis, but it surely’s unlikely the whale was sporting the harness to document his own residence movies.

The usage of animals for navy operations isn’t all that uncommon. Through the Chilly Warfare, the Soviet navy skilled dolphins for navy use, however this system was discontinued someday after 1991. America Navy has studied marine mammals, together with beluga whales, for the reason that 1960s and has skilled them to hold out quite a lot of duties, like performing restoration operations and discovering underwater mines. The Instances reporter John Ismay served as a Navy explosive ordnance disposal officer and explains the sorts of issues dolphins, whales and sea lions are skilled to do.
Sure, as unusual as it might sound, the Navy makes use of dolphins for quite a lot of missions. The Naval Info Warfare Heart, Pacific, trains Atlantic bottlenose dolphins on a base in Level Loma, Calif., whereas the Navy’s explosive ordnance disposal group makes use of the mammals for a lot of of its operations. Through the summer season of 1998, earlier than my senior yr on the Naval Academy, I used to be quickly assigned to an explosive ordnance disposal unit at Naval Amphibious Base Coronado that had a number of marine mammal detachments. One regarded for skilled enemy divers, one other regarded for naval mines floating within the water column and one other looked for mines mendacity on the seafloor. One other detachment skilled sea lions to assist get well costly objects like inert torpedoes off the seafloor in order that the Navy may reuse them.
Two huge causes. One, their bio-sonar is healthier than any mechanical sonar ever made. Dolphins produce sonar waves from their foreheads, they usually can rapidly find issues that people can not. Second, they will repeatedly dive deeper than human divers, reaching underwater depths that we may in any other case attain solely utilizing robots. The dolphins “see” enemy frogmen by sensing sound waves bouncing off the laborious calcium deposits in human bones, and may sense mines buried by mud and silt on the seafloor by sensing the air void contained in the mine’s casing.
How does the Navy do that?
The dolphins reside in netted pens suspended from floating docks close to the doorway to San Diego Bay. They’re fed a tailor-made food regimen of herring and mackerel amongst a number of sorts of fish each day. Via constructive reinforcement with meals and affection, every dolphin is skilled to establish particular varieties of goal — similar to folks, moored mines or backside mines. When it’s time to work, a sailor communicates with the dolphin by means of a mix of whistles and hand indicators. The dolphin then kicks its means up and out of the water, sliding onto a wetted mat laid on the dock. Sailors carry the dolphin to a small motorboat that’s lower right down to the waterline on one facet, which permits the handlers to drive to the search space and slide the mammal gently into the water. They then use a tool known as a transducer that radiates sure sound tones into the water to sign to the dolphin that it’s time to search. As soon as the dolphin has discovered its goal — both human or a mine — it’s introduced again into the boat, which then swiftly exits the realm in order that sailors can take over the mission. For enemy frogmen, that may imply tossing concussion grenades into the water. For mines, bomb disposal divers or remotely operated automobiles go into the water to neutralize or destroy them.
Are they ever skilled to kill?
No. That’s a standard misunderstanding. You will discover rumors all around the web on the contrary about dolphins being strapped with nuclear warheads for suicide missions, however that has by no means occurred. Their mission is solely to seek out and mark issues, after which exit the realm as rapidly as attainable; there aren’t any weaponized dolphins.
As somebody who swam round moored warships as a “goal” for the Navy’s dolphins, I can inform you that they’re amazingly quick. Enemy swimmers usually won’t know they’ve been marked till grenades begin exploding round them underwater and the dolphins are lengthy gone.
Can you are taking dolphins on ships?
Completely. That summer season we loaded the dolphins onto a padded stretcher-like equipment with cutouts for his or her pectoral fins. We lowered them into small water-filled tubs, and drove to Naval Air Station North Island close by. There, we rolled the wheeled tubs onto a C-5 Galaxy cargo airplane and flew them to Hickam Air Pressure Base in Oahu. Sailors and veterinarians tended to the dolphins throughout your entire flight — regularly spraying the uncovered tops of their our bodies with water in order that their pores and skin wouldn’t dry out. From there, it was a brief drive to the amphibious ship Juneau, the place the swimming pools have been already inflated and full of seawater.
By the point we completed work, each place to eat on base had lengthy since closed and we have been exhausted. Nobody had eaten something since leaving San Diego as a result of the rule was that the dolphins have been all the time fed first. That night time I discovered a management lesson I’ve by no means forgotten, although. The commander of the explosive ordnance disposal coaching unit at Barbers Level was a previous enlisted officer, and he knew that once we have been finished for the night time that we might probably be drained and ravenous. He rolled up round midnight in an outdated fastback Mustang with baggage of chips and a case of beer. He may have directed certainly one of his subordinates to handle us, however he confirmed up and did it himself.
Are the dolphins pleasant?
For essentially the most half, sure. One time, although, a male dolphin named Jake bought a bit aggressive with me and punched me underwater along with his snout laborious sufficient to tear an indirect muscle in my stomach. After he hit me, Jake “bowed” out of the water (leaping away from the water and splashing down) all the best way again to his pickup boat. I used to be advised it’s an indication of a really completely satisfied dolphin. A few weeks later, once I went to sick name on the Juneau to get some Motrin for the ache, the Navy physician didn’t consider me once I stated I used to be injured by a dolphin and he threatened to jot down me up. I advised him if he didn’t consider me, he ought to go right down to the ship’s well-deck and see the massive inflatable swimming pools there — every one had a dolphin in it.
