On April 8, Northrop Grumman officially unveiled its new prototype deep sea drone, the Manta Ray uncrewed underwater vehicle (UUV). This new undersea drone is designed to conduct extended-duration autonomous operations at long ranges with minimal need for human support, making it uniquely suited for a wide variety of undersea scientific and potential combat operations.
But arguably, it's most potent use could be as an element of America's anti-submarine warfare strategy.

"Russia's military woes in Ukraine."?? Uhhh what military woes exactly? You're living in fantasy land --- stop being gullible to propaganda. Russia has completely embarrassed Ukraine and NATO throughout the war. Hundreds of thousands more ukrainian soldiers KIA than Russian soldiers. Russia has more military equipment, weapons, vehicles etc than they had to start the war --- Ukraine, not so much. Russia is on the verge of completely controlling the entire Donbas region, and they haven't even had to bring out their most advanced weapons in order to do so. Fact is, NATO's tactics are embarrassingly ineffective, which makes sense considering said tactics were developed fighting against farmers in flipflops and not agaunst a real military, much less one as powerful as russia. Ukraines military is close to being non-existent bc Russia is destroying them. Ukraine would've had to give up the war after the first year if not for NATO sending troops, weapons, vehicles, supplies. The only thing Russia has shown us and the military industrial complex teŸŸoŸists is that they're even more formidable than previously thought. Sooo exactly what Russian "military woes" are you talking about? You probably believe in the Ghost of Kiev and that Russians are fighting with shovels, don't you?

Well, there are a few differences. Viscosity of the medium. The lack of compressibility of water. Corrosion and galvanic electrical currents induced by sea water and the contact between dissimilar metals. Stuff like that.
Autonomous ocean gliders have been around for almost 20 years. They were originally designed for oceanographic research cheaply.
All you have to do is change the buoyancy and attitude. Point the nose up, increase buoyancy, you go forward. Point the nose down, decrease buoyancy, you go forward.
A solar panel and a little air pump is all you need.

HERE HERE!!!
Knowing DARPA's press releases on other projects this thing has probably been in development since the 1990s and is already operating in the Black Sea.
I laughed hard at this one
My firm belief is , anytime they are asking for funding for some revolutionary new plane or other weapon, the thing they are asking for money for is already in full operation for the last 3 to 5 years and is now a cover story for something new.
@@wolfeyeraven nailed it
Agreed
My thoughts on this was similar.. anything Darpa tells us is no longer operationally relevant as an emerging technology and is already deployed.
So this is the subs version of the F-35âs loyal wingman drone.
Loyal Finman.
lol that is perfect name, I was trying think of some good, you nailed it!
Seems more like an underwater RQ-180
Lol Australia built the Boeing loyal wingman MQ28A Ghost Bat and now has a submersible that uses the same Aussie AI and is called Ghost Shark for tribute to Ghost Bat and both are Aussie animals. probably does the same as this but sadly looks more like a submersible and should of made it like this and called it Steve Irwin as died from sting ray lol..

This is the best comment Iâve read in ages
How about "SAND POWER!"...
Thank you for this.
Whenever I hear Manta Ray and submarine in the same sentence I think of the old TV series Voyage To The Bottom of The Sea.
I was thinking the same.
You must be as old as I am. That sub got destroyed every week.
or the old Aquaman cartoon series.
My thoughts exactly.
Complete with the sonar ping sound.
Fishing off the coast near San Diego, we captured an underwater drone that surveys the ocean and collects deep ocean data for weeks and months completely independently. It surfaces from time to time to transmit the data, and that's when we caught it. This technology has evidently been evolving for a long time and is relatively unknown by the public.
I can testify that offshore Maine fishermen could fill books with what they've encountered out there, if you were ever able to get them to tell a 'flatlander' about it.
To be fair, you won't get them to. Most won't even share what they've witnessed with their own families unless that family is crew, too. Even then, they're a tight-lipped bunch.
These devices were invented at the applied physics lab at the university of Washington about 20 years ago. They have almost no moving parts. The whole thing is neutrally buoyant. Inside, there is a small oil reservoir that is slowly pushed in and out of a rubber bladder that changes the buoyancy so the device can rise and sink. It has wings that allow it to glide forward as it rises and sinks. One of these was able to cross the Atlantic Ocean on a small set of batteries. They are perfectly silent and can stay on station for months. The downside is they are very slow, usually 1-2 knots. I suspect these UUAVs use a similar tech to move around on patrol with backup propeller drive when it needs to move faster.
I was an offshore lobsterman out of Portland Maine
@@danheidelthat wouldnât change the buoyancy

Very cool! back in the day I was a hardhat diver working for various Gov agencies I remember once doing a subcable inspection in 280FSW sitting on a deco platform and watching a whole platoon of huge manta rays just cruising around sucking up plankton.
How could the Russian subs know that they were never detected?. US subs used to follow Soviet subs around for weeks and they never knew it. Itâs not like when weâre done following them we announce that weâve been there.
@mikeck4609 Used to follow Russian subs? I think it's safe to say we're following them today.
Con! Sonar! Crazy Ivan!
well if you can't hear the guy following you, its easy to say you've never been detected..... That's the Russian way.
British subs always knew where Russian subs were under the Arctic and remained undetected by the Russians⊠it also makes me wonder about multi medium UAP sightings as well, could these be Military undisclosed vehicles?
@@gregh8720 And if you can hear something following you, it's probably a whale. Or at least telling your boss that you weren't followed will get you promoted.
Russian Navy can't see you even if you tailgate their ships. The smoke from Admiral Kuznetsov's boilers alone is enough to mask three carrier groups.
Just another reminder that the ocean is terrifying
and fascinating...
And wet!

I tell people that the US has weapons that no one even knows about... until it's needed.
That and SOSUS. We know where 90% of human machinery that's in the ocean.
Tic-tac anyone?
We now have a self-deploying SOSUS that can stay off everyone else's maps by moving around. Cool.
Yup I love speculating about what we have and donât tell people about
That 7th gen back engineered ET craft stuff.
We may think we know a lot, but the marine acoustic environment can just swallow your imagination. Everything makes noise. Everything makes noise. And there are far more creatures in the Sea than dry land. And most are noisy. There is communication going on in the Sea every second. Then there is that pesky wind stuff. Waves make a lot of noise. You know what doesn't? Modern subs. To hunt them you need to be at the top of your field, top notch crew, top notch platform. You end up looking for the Hole in the water, where no noise is being made. The acoustic analysis programs out there today make the ocean look like glass. Truly impressive, with ever finer sensors available as COTS, I wonder what can come next. Gravitational sensors? How far is that above IR? Happening quick. I enjoy your posts.
Really love the firepower and sea power series. Cant wait for the desert power series to start so we can get a video about the ornithopter!
Russian Sub: sir that fish just told us "Go Home"
Hah
The fact that these would be drones makes that scenario even fucking funnier.
This thing has the potential to literally be the drones of Ukraine but underwater. You would have no idea your being watched until its too late. Imagine 50 of these just sitting and waiting in chinese harbors or the east china sea. It would be a check mate to any navy.

They dive deeper .....deeper than most torpedoes can go.
And because they are so quiet , their sonar works better.
Australia has 6 AI submarine drones using the same Australian AI that is in MQ28A Ghost Bat drone..
@@micksmith-vt5yiwoah there bud, we don't even know the actual wingspan of the whitebat, or the actual name, got a source for that?
@@milklover4253 What MQ28A Ghost Bat size is online in many places just a bit smaller then a F35. But block ii Ghost bat is top secret and will go in to service with RAAF next year, bigger and can carry more weapons.

The mantaâs deployable drones should be called âLong range Autonomous Marine Patrol and Renewable Energy, or LAMPRE. Lockheed Martin you can thank me later.
Yeah we need to send out a few legged ones, too. Magnetically clamp to the hull of the sub, walk along on metallic crab legs for a while, making sure to make lots of noise, then leave. That should be interesting for the folks inside. tap tap tap-tap tap tap

Definitely one of, if not the best YT channel for the layman military enthusiasts.. Most of the channels are either sensational in presentation, form or data, while some other channels are made for engineers by the people that don't know how to transfer their obviously vast knowledge...
I especially love the fact that Alex covers all the latest developments and themes in the industry but not trying to be the first to tell the news but to be the one who covers it the best after some research...
Sure, there are more and less interesting themes and topics he covers but I love the fact that Sandboxx branched out from mainly air power to other services.. Great job
@@jeffroid_tv artistic license, my friend. If I was accurate, and said CZcams, the joke wouldnât be recognized as referring to NBCâs 1990âs slogan.
So if youâre laughing at me, start laughing at yourself, because you just made yourself the joke.
They should make a massive one the size of a small town and call it arsenal gear
Next step is for them to use whale song and dolphin clicks to communicate with each other and the US Navy. Potentially add fuel cell technology to charge internal batteries, needing to only sporadically surface for air, and youâve got the perfect submersible weapon. One that blends in perfectly with the ecological background.
Given how far those animals can apparently communicate, I think that's a brilliant idea!
Granted, it's by no means far _enough_ to be particularly useful (given the vastness of the oceans), but... perhaps non-biological means would be able to increase it enough to be.

Now you've got large, low density, high pressure tanks that will empty out and need to be offset by ballast across the duration of the mission. That adds a lot of complexity to the design.
Until it becomes covered in seaweed and barnacles.
Do you have any idea how much maintenance any underwater surface needs ? Especially anything sitting on the sea floor.
Truly a weapon to surpass Metal Gear.

Perfect timing! Thank you for another amazing video!

"Five times quieter" = Sounds like 100 stampeding horses instead of 500 stampeding horses. Great improvement!

Amazing vid as always Alex, love sharing this with my friends on FB and X
Former U.S. Navy here. Outstanding brief, very clear and thorough. I do however, detect that Alex is deftly skipping certain "topics and conclusions" for the sake of OPSEC. I admire this and love this channel all the more. Big thumbs up and lots of mentions on other military analysis threads.
Man I swear it was just yesterday I asked for this!! Awesome thanks!
We're getting closer to seaquest dsv.

Casually includes clips of a robotic whale swimming around . wtf lol
Same, like wth is that?
AI powered drones that behave like whales but are packed with explosives. The US has a miniature drone called the Black Hornet, it's literally a large metal hornet with super tech, but it behaves like a Hornet
Russia making a sub quieter than a Virginia or Seawolf that isn't diesel electric? Riiiiiiiiiiiiiight . . .
I'm gonna swallow the whole dead sea.
Russian Uber weapons đđ
My eyebrows raised as well upon hearing that it would be "two times as quiet as the Virginia class" just cause of a new propulsion system.
The fact that the most quiet US nuclear powered attack submarine class, the Seawolf, stopped production after 3 cause of the end of the Cold War and the insane cost of just building the Seawolf class, makes it really just seems like standard Russian BS.
@@aaronho1914 It will be an experimental vessel that will only see combat in a video game.

Wow, another amazing video! I always get goosebumps about all this new tech used on the battlefield. Semper Fi!!!
No one does military news and explanations better than Alex!
This is the earliest I've ever been to a Sandbox release. I wonder how I should celebrate
âSignificantly stealthier [Russian vehicle]â is an insanely low bar. Of course any actual attempt to do more stealth would lead to significant improvements. But that doesnât mean the actual vehicle has anything close to real stealth. Like a modern F-16 represents more stealth compared to most Russian aircraft but that doesnât mean the F-16 is stealthy.
And the fact that they are saying this is supposedly 2x stealthier than what America has only really demonstrates the validity of the above paragraph
The claim in the video is that the Borei is twice as quiet, meaning lower acoustic signature, than the Virginia class. I am inclined not to believe a categorical claim like that.
The underwater threat is by far more concerning in my opinion. Thanks for a nice encapsulation of the various projects underway and still in development.
I'm sure the US still has a SOSUS type of listening and tracking device around the entire northern US continent, along with permanent tethered and short term sonar buoys. I worked for a company a few years ago that manufactured military sonar buoys. Company sent me to the highly restricted San Clemente island test grounds off CA coast to test new sonar bouy designs, etc. I was completely blown away what could be heard, detected, and tracked from very far away. And the system knew exactly what and where that "signal" was. And that was years ago. What the US has now is definitely more powerful and sensitive.

I cracked up at that pirate comment, well done
The Manta looks sick!
Best of all your recent episodes !!!
Another great episode -- thank you!
Great content, Alex. BTW in my experience you are one of the very few people I've seen who looks just like I thought you would based on just the sound of your voice.
The clams are listening, Igor
I see that these projects are reviving a number of ideas I put forth in our ADP proposal to the Navy 30 years ago.
Probably not revived. The ideas were probably being developed in various military labs with non specific appropriations and out of the public eye until there was sufficient technology maturation to permit building prototypes. I am not going to be specific but I can think of some other weapons that were envisioned decades ago but one or more technologies were not ready for a full development program. Different government labs had small teams of scientists and engineers working on those technologies all those years but there was no formal program of record. They were funded by the lab's discretionary budget and while not necessarily classified the work was not publicly acknowledged.
Great stuff, Alex!
I have a lot of issues with this video, not for the content but for the projection looking from a civil engineer studying hydro.
1: manta ray shows that they are deploying a tether to go to the surface which might be great to allow for passive solar power for long term bottom. The problem with that is that the tether was shown to exit the vehicle and if that opening was open over a period of time would silt up and then not be able to retract and move.
2: Communication will be an issue with commercial bands, like it was said the first strike will be for the low band that submersibles currently work with.
- A small sat phone on a tether (depending on how deep it is) would allow for ping type communications. Messages could be brief and encrypted.
3: Sitting on the sea floor for any length of time might prevent or impede the thrust from working so a buoyancy emergency might be required....didn't see that in the requirements.
Overall, it is an amazing idea and one I would move forward with if I had a couple billion dollars, but some of the small details like electric engines cause a lot of noise....battery power, etc....all fixable but still need to be addressed.
Thanks for your amazing content for the geeks of us.
It's likely mostly using buoyancy to glide around. Lots of ways to do this fairly passively. It can let the screws generate power when it glides, so, that's not an issue either. Coms are an issue considering known technology, all of which is decades old at this point. It's very likely that they've cracked that problem long ago and just aren't talking about it.
@@jttech44 It generates energy by changing buoyancy and gliding, hence the name. The novel energy sources mentioned are only required when it is stationary.
My guess is there are no screws for propulsion at all. We get to see the public version only.
You're certainly right about the whole silt issue though.
The silting is an engineering problem it could probably flip over to de-silt. My worry is the power source. But it could harvest wave energy.
Please just once! Say "EA Sports, its in the Game" lmao
Imagine thinking that you are a stealthy sub, but Manta Ray is secretly live pinging your position, as a live ordinance is falling down your head.
If they're showing this, there's something even better down there.
Future wars will be drone on drone fighting. Guess we're getting close to the Terminator's plot in real life, how exciting
The energy generation tech is a good potential example of how military expenditures can benefit civilian sectors.
Yea there's potential synergy there. In fact, gradient tech probably works better at larger scales. It's just that the battery in the drone is probably small enough that it's sufficient. Not unlike how certain nuclear tech works great on a space probe and nowhere else.
In this instance it is the other way around. Find out how the Faroe Islands are generating electrical power from tethered underwater gliders.
Good afternoon. Thanks again.

most of the black sea fleet is composed of submarines, its a special seafloor inspection operation
When I was 10 years old I imagined a fighter jet that could also function as a submersible vehicle, and take off from and land in the waterâŠ..
The US Navy explored a similar concept about a decade ago - a flying SEAL Delivery Vehicle that could land on water and submerge. We have a video about it if youâre interested!
There was also something like that in the seventies

You underestimate my power!!
Of course you can, if it's only 20% as loud as others, it's 5 times quieter
It's not pretty, but it works
@Sandboxx Looks like the Northrop Grumman Manta Ray is a underwater sea glider much like the Liberdade Class underwater glider that the US Navy uses to detect submarines just a bigger. Underwater gliders change their buoyancy to make them go up and down and use wings to propel them forward. They are used for all sorts of research and can be at sea for quite a long time using solar power to recharge their batteries when they at or close to the surface.
Several decades ago - I had finished my Junior year in high school ... My father reduced his previous work in aviation, & increased his work in designing surface watercraft. I asked him if there were any difficulties in moving from one to the other. He replied that there was not much difference. Air and water are both fluids, they just have different Reynolds numbers.
We spent that summer building a couple of test articles (boats) in the garage ...
Give them to Ukraine
It would be good for testing

Amazing content as always Alex! Minor nitpick about the adspot at 2:59, the Navy doesnât operate any RC-135s, theyâre all USAF.
Interesting! Thanks!
Well Done ! Given the current civilian propeller developments it
would be really interesting to see the 'real' prop design...........
Especially, the one reportedly carrying the Torpedo known as Poseidon. I've followed at a distance it's development along with the 100 Mph Csvitating Straight Line Torpedo. I like that the Navy is in the design and proto type development of a Submarine using the same idea.
The nuclear torpedo Russia is developing? The usa isn't making one and doesn't really need one
Poseidon isn't quiet. You will hear it coming in plenty of time to engage it, and the subs that carry it will be tracked diligently just like SSBNs are tracked.
Our coastal water commitment is the perfect place to assign our new and unwanted Littoral ships. Find areas that fit its capabilities and use them to patrol for enemy subs. The Manta Ray's sound great, but are still years from large scale assignments.
You gotta love DARPA. God bless America!!
I find it hard to believe either one of those methods for harvesting power could produce more than a very low profile wave generator.
I feel like Alex needs another channel on CZcams for different types of content. Like reactionary to the common misconceptions in common physics in aviation, maritime videos . Its kinda crazy how far some of these are taken especially when other creators videos. Just an idea ! I really do appreciate the level of detail in these videos. Thank you!
Thanks.
04:32 ? I remember watching a documentary about this decades ago, 'Hunt for Red November' or something like that...
Disposeable Air dropped mini subs that can operate for several days at a slow pace and recharge on the surface of the ocean with solar, wave motion, current generator. Operates like a chain of sensors working like a drone swarm but near the surface of the ocean in a patrol route that interlaces with each other. Allows early detection, possible hunter killer capabilities or tracking over distance. Even attaching itself to the enemy ship or sub.
DARPA got a hold of my old sub designs from the 90s
From what I saw in the few videos that showed its actual propulsion system (screws/propellers), I do hope that they also look into new propeller/screw technology that have less cavitation when spun up. There are new propeller designs that are being used commercially that could be beneficial to the project.
General âdoes it need to be shaped like a manta rayâ
Northrop âoh yeah no no yeah no yeah 100%â
There's not many channels that duplicate the quality of your work!
Completely agree. The quality and content is top notch.
Amazing video, can we get some videos on the P8 and EA18G!
I like the imaginations that can sometimes become reality....even through our failures, we always come up with answers
Highland Systemsâ Kronos and Northrup Grummanâs Manta Ray would make a complimentary pairing with many possibilities.
Awesome! @SandboxApp, is this going to be a recurring segment?
