Top-secret US aquatic drone weapon ‘Manta Ray' spotted on Google Maps for all to see

[NY Post]As a kid I always wanted a flying sub like the Seaview's. Cool pics at link
A top-secret US submarine prototype weapon called "Manta Ray" has been spotted by eagle-eyed Google Maps users and remains plainly visible to the internet public.

Satellite photos showing the "Star Wars"-looking vessel docked at Port Hueneme naval base in California went viral Sunday, its unmistakable profile standing out like a sore thumb in contrast to its dockmates.

The smooth-looking autonomous vessel was named after the sea creature for its slick design and its ability to anchor itself deep underwater while operating in low-power mode.

Produced by Northrop Grumman as part of a US Navy project to develop long-range underwater weapons, Manta Ray is a sophisticated underwater drone capable of hibernating on the sea floor for "very long periods" without refueling.

It uses "efficient, buoyancy-driven gliding to move through the water," Dr. Kyle Woerner, Manta Ray program manager at the Defense Advanced Research Projects Agency, said in an agency news release.

"Our successful, full-scale Manta Ray testing validates the vehicle’s readiness to advance toward real-world operations," Woerner added.

"The craft is designed with several payload bays of multiple sizes and types to enable a wide variety of naval mission sets."

Its modular design enables it to be disassembled and transported in ordinary shipping containers, eliminating the necessity for dedicated port facilities.

The Navy spent more than three months testing the craft off the coast of Southern California, the Telegraph reported.

Defense analysts suspect the Navy’s push to develop drone technology is intended as a strategic counter to Russian and Chinese submarine operations, the outlet said.

Russians have been developing underwater drones of their own, and last year announced plans to acquire nearly three dozen such vessels.

The US adversary claims its drone has a range of about 6,200 miles, can be armed with nukes and can reach speeds of up to 100 knots — or about 115 mph.

#11  From "The Wabbler" by Murray Leinster, written 1942:

...The Wabbler lay in its place, with its ten foot tail coiled neatly above its lower end, and waited with a sort of deadly patience... It and all its brothers were pear-shaped, with absurdly huge and blunt-ended horns, and with small round holes where eyes might have been, and shielded vents where they might have had mouths...

Splash! The Wabbler plunged into the water with a flare of luminescence and a thirty-foot spout of spume and spray rising where it struck... It dived swiftly for twenty feet... Then its falling checked. It swung about, and its writhing tail settled down below it... and then slowly, it settled downward. Its ten-foot tail seemed to waver a little, as if groping.

Then it made small sounds from inside itself. More bubbles came from the round place like a mouth. It settled one foot, two feet, three...

The Wabbler leaned infinitesimally toward the shore. Presently its flexible tail ceased to be curved where it lay upon the ooze. It straightened out. Then the Wabbler moved. Shoreward...

#10  USN vessels will be able to talk to it.

I'm reminded of the ancient cold war era movie Failsafe.

I would expect the drone AI would NOT respond, anticipating spoofing.

#8  They are autonomous enough now that they can be given weeks or months long missions with rules for unscheduled activities or get near enough to the surface for a flash message that will top mission objectives up again. And I'm sure all the subs and surface combatant USN vessels will be able to talk to it.

#7  It is possible to communicate with a drone that is so far underwater?

Back in the day the nuke subs had to resurface for instructions.

"energy-saving technologies,” the exact nature of which remain murky, allowing it to anchor on the seafloor and hibernate in a low-power state

For the moment assume 'drive props' also serve as generators while anchored in a current. Much like EV braking.

#1  Enemy. Russia is an enemy. Venezuela is an adversary. Iran, North Korea, China, the world is better off without them. And it's not going to happen by itself.
