I don’t get the idea of having a separate pressure hull for your helicopter hangar. Surely if your submarine is compromised to the point of needing the pressure hull you are long past the point where your helicopter is going to save you.

There’s an excellent documentary series about things that go wrong with superyachts called James Bond.

Having seen that, I’d certainly invest in a pressure hull hangar if I were so inclined.

It's probably a safety concern. A helicopter hangar requires a very large watertight door. Very large doors are less safe than small doors. In the event of failure, better to lose the helicopter than the crew.

Check out narco submarines - they have people in the jungles of Columbia building submarines that they pack with tons of cocaine (literally), which are discarded after a single ocean crossing. In general, it seems to be more economical to ship illicit materials with cheap/disposable vessels and vulnerable/impoverished people, rather than risking an expensive yacht to government seizure.

I would find it funny if a country managed to bootstrap its way into high tech manufacturing like that. It sounds like the Columbian jungle would have a lot of demand for good engineering and machining know-how and if they are building disposable subs they'd have a lot of incentive to perfect cheap manufacturing technique. If the drug trade doesn't work, they probably have the expertise to get involved in navel drone…

I’m picturing a lawnmower engine inside a hot water tank running 6” below the waves, but maybe I’m not giving them enough credit.

Helicopter hanger has the largest door into a pressure hull area, it's the largest point of failure - if it fails, it's isolated from the living space (and other sub areas).

It's smart safety design.

In fact, the point I was trying to illustrate is that if they steal your fancy luxury submarine is even less expensive, it's free, gratis, 100% discount. Do you really want a ship that it's seen as disposable delivery system by every single organised crime entity on the globe ?

How are you supposed to hijack a submarine when it's subsurface?

I guess like you do for airplanes: the fact a plane can fly don't make it immune to hijacking. Example: you wait the sub is in the port, is moored, etc

You don’t want this type of sub for drug smuggling, I chased the smugglers and this massive monster will definitely be harder to operate and disguise than what they use currently.

Following your reasoning an airplane can't be hijacked because it's difficult to operate: in reality you only need a gun to operate anything, in right circumstances.

I would swear there was a company in the late 90's that sold luxury submarines. Not submersible super-yachts. I thought it was the neatest thing till I realized you needed like 20 close friends to crew the thing. And far more dollars than I had. But that was like a real diesel electric that could dive to avoid storms and cruise fast on the surface. Definitely smaller than this.

Toys are neat. I dunno, if that's what you want, go for it. I sorta feel like you can do better.

There's also the Nautilus "Luxury Yacht Submarine" from U-Boat Worx [1]. I don't think either of them have ever been built, they're basically just Kickstarters for ultra-rich people. Edit: There's a link for Migaloo NFTs on OpenSea in the footer and a fanciful floating habitat that looks like a seasteaders wet dream. This does not look like a serious project. The entire site is nothing but renderings. U-Boat Worx at…

Design student project maybe?

This actually seems to be happening already in regards to manufacturing. I read an obscure article a while back about autonomous narco submarines surfacing in Spain, which suggests a certain sophistication and standardization of the manufacturing process [1].

> The [d]rone submarines are essentially identical, suggesting series production of a refined design.

They also found a "narco surfboard" which presumably disguises drug shipments in an abandoned surfboard. In the arms race between traffickers and enforcers, I'd imagine both sides will be continuously developing increasingly sophisticated technology for underwater smuggling, especially given how much money is involved - so I could totally imagine a high-tech manufacturing industry emerge as a byproduct. I would also find it quite funny :)

It's beautiful engineering (if real), but all I can think about is the number of people that could be fed, housed, and educated for that amount of money. The world could be made a permanently (slightly) better place instead of building this.

The people building it will be fed, housed, and their children educated with that amount of money. Jobs are what the world gets out of this sort of thing.

Feeding, housing, and educating people would also create jobs. Probably a lot more jobs.
