Just to be clear, autonomous doesn't mean AI. It just means you can download a mission and from there it can operate with no further input required, but it surely can surface periodically for updates or to offload data or get a new mission.

About the propulsion system... I believe they're using a Magnetohydrodynamic Drive (MHD) which produces thrust with no moving parts using magnets and electricity. There are some interesting and informative videos made by other content creators like Plasma Channel and The Action Lab. I highly recommend watching one, maybe even try a reaction video of one of them. Love the vids, love the new business! Cheers!

EDIT: Thanks for all the likes, that happened quick! Obviously I could be wrong. But is the military not usually about a decade ahead of the public in terms of new technologies? MHD's work, they are a proven concept. It's just a matter of coming up with the right materials so that oxidation and wear doesn't happen as quickly. In the details that were released about this UUV they talk about it operating so quietly that enemy sonar systems can't pick it up.

Imagine being china and having 30-50 Orca's off your coastline and each on has enough firepower to sink 3 destroyers. All waiting patiently underwater, no surfacing. Like having underwater SAM sites but for ships and enemy subs. Like smarter underwater mines, that see the enemy and attack them when signaled.

Also each Orca only cost about 120 million versus 4.5 Billion of a Virginia class attack submarine. You could buy 38 Orcas for the price of 1 attack sub.

Sandboxx has a more detailed video on Manta Ray and they don't use AI voices. Northrop Grumman official yt channel recently put out a new video on Manta Ray.

Prolly make a great sensor platform to detect submarines, inspect communications cables, pipelines and offshore oil platforms too, and much more.

[BrianGilbert-rj]

The only way to contact a sub when it's underwater is with ELF ( extreme long frequency) which is 7 to 12 bits per second so messages would take a long time to send anything sizable. So the message sent is mostly and order to come up to antenna depth and get message.

[timsmith]

On the autonomous bit, that could be a good thing. They can't be "disrupted" like devices that use radio waves. I'm guessing they can be controlled, but are designed to go autonomous and hit depths you'd have trouble communicating with.

The manta design evokes the Moebius flying sub from Voyage to The Bottom of the Sea. It’s life imitating art.

[One_foot_in_the_Grave]

I think considering that a catastrophic failure on a submarine historically, almost always leads to the crew dying, having unmanned subs doing even half of the heavy lifting, patrolling, combat, firing missiles etc.. that's got to be a win-win right?

[CRS]

There is a channel called Megaprojects that made a video about this ~4 months ago about the Manta Ray, and they go into a bit of logical speculation about what this thing will be asked to do initially and how it can perform its tasks autonomously.

Appreciate the content and hope you have a good day.

[Benzy]

I actually love both of those can designs, the green is fantastic. Why not just have those be the two sides of the same can?

Also, with the news of aliens supposedly in our ocean, really makes you wonder what these autonomous subs are secretly going to be used for. Convenient timing to have unmanned recon subs, don't you think?

[bierce]

The wings of the manta ray suggest a propulsion method. As it submerged, it would glide forward just like the gliders in the air. But even better, it would glide forward as it surfaces, too. It could undulate up and down in the water repeatedly to pick up speed. Imagine how quiet that would be.

[goblenator]

As a FedEx Express driver i enjoyed the Ring camera bit LOL

[TrulyUnfortunate]

Woah!!!
That prop looks crazy!!
I've bought a few new props for my bass boat with a 150 Mercury that are supposedly the new and best props out there and have had limited success.
Some tend to cavitate while others lack in the thrust category.
So far your standard prop is better for all around performance.

[josephmumma]

BOTH, I’m looking at both sides of the can. Awesome job !!

Actually, mostly unmanned warfare has been acknowledged as a very bad idea, because once you don't have to worry about sending Pine Boxes home to loved ones it becomes easier to go to war.

[davidrust]

Inertial navigation is a tried-and-true method of underwater navigation used for many decades and quite accurate. Sub's periodically may stick up a mast to get a quick sat fix to correct any errors, then continue on. Very little of the ocean floor has accurate mapping, so I'm not sure contour matching would be that reliable like for missiles. It's doubtful the Manta Ray uses AIP for propulsion being so small. I would think the Ray has fairly neutral buoyancy and uses mostly control surfaces to set depth but likely also has some capability to change buoyancy, especially for resting on the bottom. Pushing water from ballast takes quite a bit of air pressure and there's not a lot of room to hold air flasks. I suppose it could also use an electric pump powered by the battery.

[Yuki_Ika]

one detail Discussed by Northrup Grumman (makers of the Manta Ray) is that it should be able to anchor itself to the sea floor and send an electricity generating probe into the water (think like how those electricity generating windmills work, just underwater) to refill battery power at least somewhat

[jaryncovell]

12:25 that was such a British conversation😂

[GoldBld]

Inertial Navigation doesnt just use prediction, its based on accelerations experienced by the sensor.
