The Secret Stealth Boat that Flies Underwater 

Wow this is so cool, I'm a US Navy submariner and I remember seeing this exact vessel on "Display" between 2016 - 2018 at PNSY where I was stationed. We always walked past it and made jokes that Batman joined the Navy

it's really sad to see such a masterpiece of technology being just there on land only to be displayed

A classic case of “it’s good, but we don’t want it and nobody else is allowed to have it either”.

What I find most amazing is that this only cost $22M to make. I can imagine the cost if you the navy had commissioned a project similar to that.

This feels like a thunderbirds base of operations! In a good way. An impressive feat of engineering.

This seems straight out of James Bond! That shape reminds me of the stealth ship from Tomorrow Never Dies!

As engineers, stories like this are so disheartening. We develop something great, only to have it stolen, or squashed by the government.

Fascinating… These days when there are so many standards of design it is rare to see this kind of creativity and ingenuity. Sad they didn’t want to buy this and then screwed over the company so other people couldn’t use it. They knew it was good.

cant imagine how they can come up with this stuff. truly amazing

I noticed a thumbnail before noticed the channel, I’m so glad it’s not click bait! This channel is awesome! This channel & Dark5, knows the topic, keeps us entertained and learning something new that pretty much is not what you think that you thought you knew about something you have thought about, and assumed!

I attended a symposium about 10-12 years ago about maritime combat operations in the future. All the “experts” there seemed to agree that the bulk of maritime combat would take place in littoral zones. I forgot the exact number but something like 95% of the world’s population lives within a couple miles of a major body of water so, this type of craft makes sense. However, the experts there said that traditional props were almost not an option and jet drives were the word of the day. IMO, jet drives have a similar level of vulnerability, just different. Cavitation and debris are still huge issues just in different ways. Especially with assault crafts, landing on a shoreline or beach is still tricky. Part of our SOP for insert/extract on a beach was to reverse the jet drives themselves(not reversing the boat with buckets) to remove obstructions from the intakes. That said, I think the Ukrainians are showing the “experts” how it’s really going to go down- a sea of unmanned kamikaze drone ships that were built using off the shelf parts from Amazon or alibaba. A $500 bundle of stuff ordered online has taken out bridges and billions of dollars of high tech warships.

Personal opinion: Make them even smaller, cheaper, and unmanned/slaved to the destroyers. Then you've got yourself a winner. Manpower is expensive, and if you don't *need* to have these deployed actively at all times, then you also don't need to worry as much about range. All it needs to carry is sensors and a light load of munitions. Enough to disable 1 - 3 threats. Deploy as needed, in larger or few numbers, replace easily.

Well, when you remember that the inventor of the jet engine, an English man, wasn't supported by his government, that as early as 1937 they had a working jet-propelled aircraft but stopped research, and that all his work was given to the motors manufacturers like Rolls Royce because of the war effort, being an inventor in strategic sectors is a hard life.

Engineers are so under appreciated. Thanks to all of you

This is the most Sci-fi looking boat i've ever seen! wonder if this type of hull can manage rough seas with 3 ~ 6 meter (20 feet) waves

I don't know why but, the Ghost do be giving me some Roblox Sharkbite vibes

I remember this boat is was one of the best ships in Sharkbite

My therapist: The amphibious Star Trek shuttlecraft isn’t real. It can’t hurt you. The amphibious Star Trek shuttlecraft:

Britain has their own submersible small boat as well. I’ve seen the prototype in testing It’s called the Subsea Craft VICTA for anyone wondering

I remember seeing photos of this thing circulating years ago. I wanted to use it in a sci-fi story I was writing at the time. 😅

Being that this craft was built by a company outside of the Military Industrial Complex it was dead on arrival. Our government loves its mega conglomerates that employ retired Admirals and Generals.

Looks like something from a videogame. Can't wait to see this in Just Cause 5

I like the moderators tone of voice. It straight forward with no sarcastic inflections. Great job.

I lived in Portsmouth, NH when this ship was in limbo. It sat in a vacant lot next to the highway for years. Sad to see but really cool to look at driving over the Route 95 bridge in between Kittery and Portsmouth.

US Navy Sea Shadow was built in 1984, no secret. There are active suspension catamarans that can ride smooth in rough water, or the passive approach where the pontoons are flexible air inflated sectional.

A design like this seems like it could find a place among the coast guard.

One of the coolest things I’ve ever heard of!

I remember seeing a show on TV about these ships, most were science vessels because they remained level in bad weather . They showed a regular hull getting beat up in the distance beside one of these ships and they had a glass of water on a table and it barely titled. Thank you

The sad truth is doing business with the DOD is like doing business with the devil.

It looks like a James Bond kinda boat

I've never heard of this boat. Amazing piece of engineering

I drive past the one in Portsmouth almost every day! Great to see some more info on it!

thats the boat from sharkbite

A viable and cheap option is to go for a catamaran fast attack craft equipped with dual purpose 35 mm CIWS that can provide anti-surface and anti-air capability against fast boats and aerial threats.

Error: The narrator said that the Ghost has a "Supercavitation Hull". This is wrong. The Ghost uses "cavitation bubbles" to reduce water resistance accross the SWATH hull. That's called "bubble lubrication". Supercavitation hulls are something totally different and are still very much in the experimental and testing phase. The Ghost was a sea vessel that advanced a lot of theories about propulsion and stability. It's a fantastic ship built by a visionary engineer and designer.

Cool boat. Was just at the albacore museum with my son a few months ago and saw it in display. Very futuristic looking ship.

Sea Shadow. Biuld by Lockheed in the early 80's (completed in 84). It was an experimental stealth ship. It looked just like this. But was a full size ship. It had a staring roll in the Pierce Brosnan Jamse Bond film "Tomorrow Never Dies" in the 90's as the bad guy ship in the end of the movie.

Spent a lot of time underway on GHOST. An interesting craft...to say the least.

i pass by this boat frequently!! Its so cool

Another super presentation😃

I applied for a job with them, had an interview 2013. At the time it was on sea trial pre dawn. I didn't get the job because I had no experience in the military. Looking back now, I am glad I didnt get the job.

i didnt know this was a real boat😳

Very interesting. Another excellent video...

gotta love the Ghost, especially when you always drove past it

I've been designing something similar for the past few year's. I hope I don't run into the same problems. My design uses the Swath 3 design, has a heli deck and able to dive down to 130'. My design is not military based. But oceanic research. It's still government funded. My design is based on stability not speed. I'm looking at max speed to be around 28 mph (24 knots). It's what the craft does and what the second part is that makes the whole thing nice. I figured the full size will cost around 60 million dollars and has the ability to have a revenue of around 500 million per year. It can carry up to 22 scientists/ customers.

Yo it’s the sharkbite boat!!1!!1

Brilliant propeller design.................using the bubbles generated by the props being placed in front of both the subs to dramatically reduce drag..........................I immediately thought how this concept could be applied to ftl travel....................TY "Not What You Think"..................Michael;)

Thank you very much for the video I love you I watch all your videos

Around the early 1960's, the secrecy act was also applied against the inventor of the laser. I can understand the defense department wanting to restrict such developments from being snapped up by adversaries. But I don't understand why they don't at least provide just compensation, and then fund a small scale research effort to evaluate its potential. In the realm of defense and 'black' budgets, a few million$ as compensation for secrecy would. not even amount to 'chump change'.

Impressive. Interesting design

No way, I accidentally found this museum while visiting the US and was trying to find videos on it. Glad somebody is paying attention to it.

This reminds me of the IX-529 Sea Shadow that a bunch of engineers working on the F117 Nighthawk made as a concept stealth boat.

I'm wondering if the limited range of the craft is really much of a factor, since the purpose of the craft is to provide protection for the fleet, and the craft will fit inside the well deck of a larger ship within the fleet. Also, the addition (or, more likely, the substitution) of a more efficient power source could reduce the volume of the overall system. All of the spaces used for fuel can be used in other ways.

Seriously, as many have already mentioned, you cannot talk about this ship without mentioning the Lockheed Sea Shadow. This guy was looking for a payday using a concept that had already been rejected by the Navy.

So this is where Sharkbite devs got the inspiration from

1960's technology put to new use. The Americans Milatary and other's had boats / Hydrafoils .there are rare examples a few still opreratable. Very fast and versatile for the times. Keep up the good work.

This boat is sitting on a dock in Portsmouth, NH and has been there for years. Clearly visible from the road next to the dock.

Sounds very American to not take what obviously would be a big advantage for them and disregard and not take the opportunity to buy and use this technology to their advantage BUT they also don't want any other countries to get their hands on it either. Makes ya wonder what it is their doing

Completely mind-blowing! Innovation knows no bounds.

cant imagine how they can come up with this stuff. truly amazing. Engineers are so under appreciated. Thanks to all of you.

I am so, so tired of the US government.

I think they should be incorporated into carrier groups. Just build a big ship to carry and deploy them when needed or, more like what the US would do, alter something we're already using to do it. If smaller boats have such tactical advantages, then why not take a bunch of smaller boats out with you. At the very least, a ship spitting out a bunch of those would be intimidating, and at best, they can neutralize the smaller boats that might be attempting to hit our ships in coastal waters

Love your vids

"fly under water, through air" and does not need energy nor crew. BRILLIANT

at first I thought this boat almost looked like from Star Trek 😀

The US Navy has a gaping strategic hole in their battle order, and large hull naval ships may soon become a thing of the past. With better and faster anti ship missiles and torpedos large easier to target ships ships days are numbered in any open conflict. Smaller more numerous PT and torpedo boats are key and the US Navy hates them just as the US Air Force hates helicopters. Sure you would would probably need to deliver these smaller ships around the world in an actually conflict and they wouldn't be able to arrive in an area to exert military pressure during peace time. But the US Navy seems to have a lack or preparedness to be able to whip up hundred if these kinds of ships in case of outbreak to war. The US Navy is the most expensive of the military branches and will suffer the most catastrophic losses at the outbreak of the next war, and they are happy to wastes billions on faulty big ships that won't even last until then.

A Revolutionary product from a Genious‼️👏👏☮️

Huh I stopped at Albacore Park the other day and was wondering what the story with this thing was. Pretty neat that you came out with a video on it around a month later.

IS THAT THE SHARKBITE BOAT!!!!???? 😲😲😲😲😲😲😲😲😲😲

just imagine the amount of failure points those articulated legs are going to have and the logistics needed to bring a significant amount of these boats out into the sea. Of course the navy was not going to buy that white elephant.

The longer version of the ghost mentioned in this video would be a perfect base to design a dedicated CWIS point defense class around. Stable, fast, manuverable, hard to target.

love your vids

Why don't torpedoes have propellor in the front?

👋🏿Hi from Philippines

Saw this thing when I visited New Hampshire last year. Had no idea what it was at the time, other than that it was privately owned and experimental.

Agreed, drinking a cup of coffee while making War is a Great Sales pitch

Which country you are watching the video

This ship looks good, but it seems like an over-thought boat, we would have to see how it fares in combat and pray that doesn't become another ultra expensive toy

Why is it always the coolest ideas and designs that we never end up seeing come into the mainstream

Great video...👍

A little too late? With AI powered surface sea drones that's 1/20 of the cost (if that), zero possible life loss, 24/7 perimeter defense Above/Surface AND - below , non stop refueling capacity from the mothership and most importantly, it never needs coffee! Re-market it for civilian police use.

Frontal props have been considered for hundreat years+ and considered a bad idea since then. First, a pulling allow teh gap between hull and propller to open forcefully, making sealing a horror. Then it creates instability to the vessel, and the water displacement creates a counterforce while pushing against the hull. The thing with cavitation is not new also, and made on supercavitation torpedos, f.e. Still this isen't SC, but some smaller kind of the same idea. The problems with this is that cavitation is the one thing propellers try to avoid like cancer - because for props, it IS cancer. Cavitation are in fact a bazillion little detonations on yor blade, wearing it down in no time. While i can't see how underwarter gas turbines should lower noise levels (water is the best sound medium around), cavitation effects are are headshot for silence anyway. Not that this type of sound detection would be much of a thing for such boats, but anyway - its just a weird arguement imho.

Very well done. Love the editing and reporting. Keep up the great work. 👍

"Not what you think" Literally what I thinked

where can i buy this? im planning to kill some sharks with it

No way, they got da stealth submarine from Sharkbite (Rip Sharkbite 1)

Ive wanted one of these for a long time

It looks interesting. I am not sure how well it will do on the high seas. It looks more like a patrol craft, or even a high end yacht..

As far as I know: they said they will help develop it into a potentially useful ship; in exchange for exclusive use of the designs and tech (not uncommon with military tech) -he said no because he wanted to also sell to foreign militaries and civilians. He had patents and demonstrator but he didn't have a viable product, he needed alot more money and help -all the gov did was bar him from getting that money/help from foreign countries but when he asked to discuss working with allied countries; they let him....seems pretty reasonable tbf and pretty far from sensationalized conspiracies.

Cool and completely useless all at the same time

Absolutely need it

I've worked in the yard they have this thing currently stored, thought it was cool as all hell.

Absolutely tragic. I hate our military-industrial complex so much. They told him to sell the rights or they'll make it classified so he can never succeed. As an inventor, I'm utterly disgusted by how our government "fights for freedom" yet all this man wanted was the freedom to own and sell what he spent his life on.

Do "Hunter Biden's laptop...It's not what you think!"

The big defense companies hate competition.

So proud of you sister ❤

CLICKBAIT... BULLLL.. this ship does not go underwater

very very interesting and cool ty

Omg I remember seeing this as the cover of a pop mech magazine back in the day.

This has many interesting features.
