Navy develops 'GhostSwimmer' drone that looks like a shark. Seriously.

Navy engineers have developed an unmanned underwater vehicle that looks and moves like a fish. The GhostSwimmer is currently being used to gather ocean and weather data, but could one day be weaponized.

It is the latest offering in what the US military calls its science-fiction-turned-reality projects: the GhostSwimmer, a reconnaissance robot with an exterior shell built to look a lot like a shark cutting through the ocean depths.

It is the latest experimental addition to the Pentagon’s burgeoning fleet of unmanned underwater vehicles, or UUVs in Navy parlance. 

At university labs across the country, for example, the Navy is bankrolling the creation of robotic jellyfish, which mimic the efficient natural movements of the ocean creature and could one day prove useful in underwater surveillance.

There are also Office of Naval Research projects to mimic the nearly wake-free undulations of the eel.

The GhostSwimmer is designed to recreate the propulsive power of the tuna fish, though it resembles a shark, complete with dorsal fin.

Coming in at five feet in length, it weighs roughly 100 pounds and can operate in water depths ranging from 10 inches to 300 feet, according to the Navy.

“GhostSwimmer will allow the Navy to have success during more types of missions while keeping divers and sailors safe,” Michael Rufo, director of Boston Engineering’s Advanced System Group, which developed the UUV for the Navy, said in a Navy press release.

The Navy put it to work off the coast of Virginia Beach, Va., with sailors controlling its movements through the use of joysticks. 

It is part of a project named after a Disney fish – deemed Silent NEMO – developed by the chief of Naval Operations Rapid Innovation Cell, in which young Navy service members are often asked to quickly incorporate cutting-edge technologies into devices the military can use.

In this case, it’s an effort to “take the lessons of Darwinism, and apply them,” says Christopher Harmer, senior naval analyst with the Institute for the Study of War, and the former deputy director of Future Operations for the US Navy’s Fifth Fleet.

“It’s a big leap forward in terms of propulsion,” he says, adding that a ship’s propeller, for example, is a “relatively inefficient” means of propulsion. “We haven’t been able to mechanically replicate what a fish does until now.”

For the time being, the Navy has said that GhostSwimmer is being used to gather data on tides, currents, wakes, and weather conditions.

In the future, it could be tasked with swimming into hostile waters for reconnaissance missions, Navy officials say.

“Anytime you have a new, groundbreaking technology, you’re always going to apply that in a low-risk fashion in order to understand what it can do,” Mr. Harmer says.

“Right now we’re using them for gathering environmental data. As the technology matures, we’re certainly going to use them for reconnaissance, and eventually, we’re going to weaponize them,” he adds. 

“There isn’t any ground-breaking technology that the military hasn’t found some way to eventually weaponize, Harmer says.”

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
