Tour the World’s Most Luxurious Submarine Superyacht

If yacht owners really want to put everyone at port to shame, they should consider sailing on the Migaloo Private Submersible Yacht. A concept yacht created by Migaloo, an Austrian design and engineering firm, the line of luxury superyachts offers a range of bespoke underwater crafts that vary in size. After sailing the new Migaloo submersible yacht on the water, owners can close up the decks and turn the craft into a fully operational submarine.

“What we are attempting to do is to create a living space where exterior and interior interact in harmony,” says Christian Gumpold, managing director and head of design at Migaloo. With rooms that open to the ocean for dining alfresco while above water, and large viewing galleries for taking in the marine life when submersed, the Migaloo creates that harmony. What’s more, the firm reaffirms its focus on luxury with optional amenities that include helipads, swimming pools, movie theaters, elevators, wine cellars, libraries, and private terraces.

Of course, safety is a major focal point as well. Each superyacht will be built to U.S. Navy SUBSAFE safety standards, which ensure that the interiors will stay watertight and the vessel can recover from unanticipated flooding. According to Migaloo, solitude is a major point of interest for yacht owners, which is why the ability to dive beneath the surface and out of view might have great appeal. “Privacy is a big issue on superyachts,” says Gumpold, “our answer to this concern is simply submerging the vessel into complete privacy.”

“People that have decided to buy a yacht will now have to consider if their vessel of choice can also dive down to 200 meters,” U-Boat Worx chairman and founder Bert Houtman said in a statement.

The superyacht submarine will be able to stay underwater for up to four days, but can only cruise underwater for six hours at a time. As an added bonus, the Nautilus can make a quick escape in the face of choppy waters.

“If the sea becomes too rough, you simply dive and continue your voyage in comfort,” Houtman adds. “With the Nautilus, the yachting market will never be the same again.”

The luxurious interior offers all the comforts of a superyacht and can be fully customized by the client. As standard, the layout comprises a combined lounge and dining area of 538 square feet, along with a fully equipped galley, one owner’s suite, four staterooms and sleeping quarters for up to six crew. You’ll have some pretty incredible underwater views, too, thanks to the large circular windows throughout.

When above the water, seafarers can make use of the massive sundeck, which is equipped with a freshwater pool, a bar and an alfresco dining table. This area is neatly retracted before the sub slips below sea level, of course. The Nautilus is also fitted with a new, pressure-resistant electric tender called the Aronnax that can transport up to five seafarers to underwater dive spots. The tender is stowed under the aft deck and stays outside while the Nautilus is diving.

The most compact private submarine

Super yacht sub 3.

Versatile, smart and capable with a design that will satisfy the highest expectations of discerning superyacht owners.

The fully acrylic hyper-hemispherical viewport gives you the best panoramic view of the underwater world possible.

Freeboard is the height between the hatch and the waterline. The Freeboard Extender is a sliding barrier that increases the distance between the water and the hatch opening. It simultaneously allows for the submarine to be operated in rough conditions and be stored in low-height garage spaces.

The latest in Lithium-ion battery technology is used to give our submersibles the ultimate performance, lowest weight, smallest footprint, and best endurance possible. The Lithium-ion battery can be quickly recharged and is maintenance-free.

The powerful thrusters and the excellent manoeuvrability of the Super Yacht Sub 3 boost superior surface performance. You will be able to go faster, manoeuvre better and expand your operational window.

This compact ultra-wide (130 degree) field of view instrument has a range of 100 meters acting as a second set of eyes when navigating the subsea terrain.

External equipment comprising a selection of subsea robotic arms together with work platforms and collection baskets can be installed on most of the U-Boat Worx models.

The red buoy is characteristic for U-Boat Worx submersibles. When released it marks the position of the submarine on the surface. The Dyneema Rope attached measures 1.5 x the operating depth of the submersible, and is strong enough to lift it to the surface.

The U-Boat Worx Information System (UIS) gives the pilot direct access to all relevant information on a clear touch-screen display. The PLC-based network of sensors ensures the right information is provided at the right time. The UIS makes diving effortless.

The acrylic pressure hull accommodates two luxurious leather seats which can be customized to your taste.

The best dive experience

This submarine is aimed at the yacht markets where an ever-growing number of seaboard owners are discovering the world below the waterline. This compact and lightweight model delivers both performance and luxury.

Clearest View

The ground breaking pressure hull design provides a virtually unimpeded view; everyone on board can easily see the hidden secrets of the deep.

Unparalleled comfort

With the U-Boat Worx Super Yacht Sub 3, we have aspired to create the ultimate in luxury interior design. When onboard a Super Yacht Sub 3, guests enjoy exhilarating views from a sumptuous chair in a comfortable air-conditioned environment with variable airflow, adjustable from each seat. You can also enjoy music from a hi-fidelity Bluetooth sound-system and even chill your favourite drinks in a cold-storage box.

Unrivalled mission-adaptability

The Super Yacht Sub 3 outperforms on every level – flexibility, agility, economy and power. This exceptional submersible features the Freeboard Extender and other smart engineering solutions.

Designed from concept to be dive-ready, U-Boat Worx has kept pre-dive checks to the safest minimum, allowing for quick and easy deployment.

SPECIFICATIONS & FEATURES

• Depth 300 m · 1000 ft
• Occupancy 2 passengers · 1 pilot
• Weight 3,800 kg
• Endurance 12 hours
• Length 320 cm
• Width 244 cm
• Height 174 cm
• Battery 21.6 kWh
• Propulsion 2 X 6.4 kW 2 X 5.5 kW
• Speed 3 knots

Lithium-ion battery technology

Freeboard extender, manta controller, marlin controller, auto-heading, omni-directional operation, container fit, single lifting point.

The MANTA Controller allows for pinpoint precision manoeuvring. The intuitive controls allow for supervised passenger steering, offering passengers an even more exciting experience. The controller allows quick access to intelligent pilot assistance functions such as  Auto-heading  and  Auto-depth.

Developed to make  Launch & Recovery  effortless and efficient, the MARLIN Controller is a wireless remote to navigate the submarine on the surface. Once the submarine is in the water the controller can be used to navigate it away from the support vessel without a pilot inside. It can also be used to bring the submarine into position above a dive site or for easy passenger transfer.

With Auto-depth engaged, the submersible will hold steady at its current depth. When applying vertical thrust, the function will automatically disengage and seamlessly respond to the pilot’s commands. This function is part of the  Intelligent Pilot Assistance   Features.

When Auto-heading is activated, the submersible will automatically hold its current heading, whether following a course or facing an object of interest. This function is part of the  Intelligent Pilot Assistance   Features.

The U-Boat Worx Information System (UIS) gives the pilot direct access to all relevant information on a clear touch-screen display. This PLC-based sensory network ensures the right information is provided at the right time. The UIS makes diving effortless.

Apart from the basic forward, reverse, up and down movements, the submersible can also move laterally. Lateral movement greatly optimises object approach, view, and dive efficiency.

This submersible is designed to fit in a shipping container. Perfect for when the submersible needs to be transported to and deployed in different locations.

The single lifting point makes launch and recovery quick and easy. By only having to attach at one point – to the crane – you create a safer environment. With the rapid-release and efficient-connect lifting gear, you can be quickly in and out of the water.

Maximum depth protection

Deadman's switch, drop weight, safety buoy, dnv certification.

The MDP feature prevents the pilot from diving deeper than the submarine’s maximum operating depth. In case the submersible should ever find itself too deep, this safety feature will automatically raise the sub until it is once again within its ideal depth limits.

This DMS safety system will automatically resurface the submersible in the unlikely event that the pilot becomes incapable of controlling the submarine. The pilot needs to acknowledge the DMS every 10 minutes, otherwise it will initiate the ascent procedure.

This weight can be manually released from within the submersible to increase the buoyancy of the submarine and return to the surface.

A very advanced USBL system is available that relays GPS data to the submersible’s on-board computer via integrated underwater modems. Piloting with real time positioning and supporting text data provides for accurate and efficient navigation. The DVL (Doppler Velocity Log) delivers real-time ground speed and position data linking to the on-board computer system.

Certified by leading classification society, DNV, requires each individual submersible to meet stringent and extensive rules and regulations, as well as pass a range of rigorous test and trials from design to final delivery. Overseen by independent surveyors, this is an independent verification of the safety of every U-Boat Worx submersible.

Written by Zuzana Bednarova

65m undersea superyacht Phoenix 1000 is a personal luxury submarine built by US Submarines. Submarine yacht Phoenix 1000 is the single largest private undersea vehicle ever built, and probably one of the most important personal transportation devices of the century.

US Submarines Phoenix 1000 submarine

213´ luxury submarine yacht Phoenix 1000 has more than ample space. The total interior area of the submarine is in excess of 460 square meters (5000 square feet). The significant volume, coupled with very large acrylic viewports, and the potential for relatively large open spaces, results in a vehicle as luxurious as the finest of motor yachts.

Clearly, underwater super yacht Phoenix 1000 provides its owner with substantially more capability than a simple yacht – the opportunity to explore the depths of the world’s oceans in perfect comfort and safety. The Phoenix 1000 yacht is capable of making trans-Atlantic crossings at 16 knots yet can dive along the route and explore the continental margins of some of the most fascinating waters on earth.

US Submarines Phoenix 1000

And unlike surface yachts, when the water gets rough, the submarine can submerge into a perfectly smooth and quiet environment, continuing on toward its destination, providing a ride unsurpassed in quality-unequaled by the finest motor coach or the most luxurious executive aircraft.

At 65-meters (213 feet) in overall length, and with a beam in excess of 8 meters (26 feet), the Phoenix 1000 is a vehicle of formidable size. Yet despite its 1500-ton displacement, the submarine is quite streamlined. Given the significant waterplane area and ample internal volume, which allows for greater battery storage, the Phoenix 1000 yacht will out-perform smaller counterparts in surface speed, submerged speed and submerged endurance.

Phoenix 1000 luxury submarine

The large pressure hull diameter allows for very large acrylic viewports, making the undersea viewing capability truly extraordinary. The interior space, with the noted absence of structural bulkheads, provides for tremendous versatility in interior layout and space planning. And finally, the Phoenix 1000’s large size coupled with its integrated roll stabilization system makes surface transit quite comfortable in all but the worst conditions.

Flying Bridge

The uppermost level of the vessel is the flying bridge. This area is similar to its equivalent area on most yachts, with the exception of the fact that the materials selected are subject to immersion in water. Ample space exists for lounging, and cushions may be brought up from the area below. The flying bridge also houses the pressure-compensated radar radome, GPS antennae and satellite communications radome, as well as radio aerials, running lights, etc. A remote steering station is also available.

Luxurious interior of the Phoenix 1000 undersea superyacht

Deck Saloon

Immediately below the flying bridge and accessible through a large hydraulically operated hatch and a stairway, is the deck saloon. As proposed, this area would be composed of structural acrylic cylindrical sections 2.1 meters (7′) in diameter and 20 centimeters (8″) in thickness. The overall length of the deck saloon pressure hull would be 12 meters.

The deck saloon would have a comfortably appointed interior and would boast an incredible view for observation, both on the surface and when submerged. By fitting transparent sections into the deck of the flying bridge, a view above can be enjoyed as well.

In the forward portion of the saloon is the surface bridge. This area contains all the necessary control, monitoring and navigation equipment to operate the submarine in the surfaced condition. The captain has a hemispherical sector acrylic viewport immediately in front, with the transparent cylindrical walls to either side.

The aft portion of the saloon has a large acrylic window, providing a view astern that also acts as a large hydraulically operated hatch. A small automobile could be kept in the aft section if desired.

Superstructure

The superstructure itself is composed principally of aluminum (or FRP if the owner prefers), and it houses the deck saloon pressure vessel and also provides the structural base for the flying bridge. There is a large degree of latitude possible with regard to the styling of the structure, with the caveat that its hydrodynamic efficiency will have a significant effect on the submerged speed of the submarine.

Aft of the deck saloon is a covered space that can be either fully or partially enclosed. The greater the degree of closure to the after portion of the structure, the less turbulence and the more hydromdynamic efficiency. Hydraulically actuated after doors could be designed to open, allowing fresh air to circulate. The area would be excellent for covered, informal, deck-level dining.

Docking Minisub

Aft of the superstructure, or optionally, above the control cabin on the bow, is an area for a docking minisub. Utilizing a special docking collar, this vehicle is capable of leaving the Phoenix 1000 superyacht while submerged and making excursions down to 610 meters (2000 feet). With both top and bottom hatches, the minisub could also bring passengers from the surface to the submarine lying at depth. The minisub could be designed to hold between two and eight passengers, depending upon the owner’s preferences. Additionally, in the unlikely event of an emergency at depth, the minisub could be used to take passengers and crew to the surface.

Forward Control Room

The forward control room is entered from the main deck through a watertight, pressure-proof door. The control room has a 2.4 meter (8′) diameter hemispherical sector acrylic viewport forward and three 1.8 meter (6′) diameter viewports on either side, with the foremost pair angled slightly forward.

The control room contains all of the control and navigation equipment necessary to operate the submarine while submerged. The 8 meter x 4 meter (26′ x 13′) area contains sufficient space to fit comfortable lounge chairs for passenger observation while underway.

Main Passenger Areas

The main passenger area consists of two decks, each 31 meters (102′) long and 6 meters (20′) wide. The upper deck is accessed from one of two hatches, either from the deck saloon or from a hatch to the after portion of the superstructure. Two stairways, one in the center of the deck, the other in the after section, lead to the lower deck.

The upper deck is intended to provide space for an engineering workstation, a switch and contactor room, crew cabins and mess, as well as the galley. The forward portion, which ends at a bulkhead, is designed as a room of the owner’s choosing.

The main deck is situated such that the forward portion, with eight 1.8 meter (6′) diameter acrylic windows, contains the living and dining areas, while the section aft of the beam houses the owner’s stateroom and guest cabins. Five viewports, 90 centimeters (35″) in diameter, are situated on both port and starboard sides.

Below the passenger area is the battery compartment and bilge. A narrow manway allows access through the compartment for battery maintenance.

Engine Room

The engine room is accessed through doors at the after portion of both passenger decks. The space contains the majority of the equipment necessary for the submarine’s operation, including the main diesels, motor generators, drive systems, air compressors, hydraulic aggregates and life support systems. The upper level of the engine space provides access to the minisub, and in the stern section, to a diver lock-out chamber. The bottom level allows maintenance of the main engines and related components. Diver Lock-out Chamber

A spherical diver lock-out chamber, 2.4 meters (8′) in diameter is fitted above the shafts and attached to the aftermost section of the pressure hull. The chamber allows a diver to enter or exit the submarine from the area between the shafts at depths of up to 45 meters (150′). The chamber can be fitted with decompression capability if required.

Move over jet skis: The new onboard gadgets the ultra-rich seek for their superyachts are submersibles.

• The world's super rich have increasingly sought out superyachts in recent years.
• One way the ultra-wealthy are now accessorizing their luxury ships is with a submersible.
• These vessels can cost at least a few million dollars each.

Joyrides on jetskis while sailing the high seas on your giant yacht are so last year.

Now, the world's .01% are seeking submersible vessels to accessorize their latest superyacht purchase, The Washington Post reports.

In 2021, sales of superyachts —yachts at least 120 feet long — reached record levels during the COVID-19 pandemic, Insider previously reported.

And these luxury vessels have only become larger, along with the demand, as the number of billionaires has grown in the past few years.

"You have a mega-yacht, a super yacht — a submersible has become the next thing to have," Ofer Ketter, co-founder of SubMerge , which facilitates private submersible expeditions, told The New York Times.

Amazon founder Jeff Bezos was recently spotted sailing the Mediterranean Sea in his $500 million megayacht Koru, which is 417 feet long.

There are several other expenses the uber-wealthy may want to consider with the purchase price of a superyacht, which, according to the Post, can cost at least $10 million.

There's gas, maintenance, storage, insurance, and, of course, staff to take care of guests on board.

But they may also want to include a submarine to explore the deep seas with their friends.

"Yacht owners are, by and large, people who have an interest in the ocean," Patrick Lahey, founder of Triton Submersibles , previously told Insider. "They like to go places and experience new things, and there's nothing quite like seeing the ocean from the perspective of a submersible."

This interest from the ultrawealthy was highlighted earlier this year after the OceanGate submersible imploded in June, instantly killing all five passengers. The company offered seats to visit the sunken Titanic ship in its vessel, Titan, for $250,000 per passenger .

The disaster may have sparked more interest in extreme adventures from the wealthy, Phillippe Brown, founder of Brown and Hudson travel company, previously told Insider.

At Triton Submersibles, a vessel can cost between $2.5 million and $7 million, Insider reported.

Similarly, SEAmagine, another submersible company that began in 1995, sells vessels that accommodate 2 to 7 people and cost the same amount as Triton's submersibles.

One of the company's models, the Aurora-80, can reach depths of up to 3,300 feet.

Ian Sheard, a principal engineer at SEAmagine, told the Post the vessels aren't actually parked inside the yacht but instead rely on what he calls "the toy hauler," which is just a "shadow ship" that follows the superyacht and carries all the goods that can't fit on the main ship.

"Even after a thousand dives, it never stops being exciting," Charles Kohnen, co-founder of SEAmagine, told the Times.

Operating submersibles on board

Two superyacht captains discuss the impact these high-tech pieces of equipment have on operations….

For owners and charter guests seeking unique and adventurous experiences, having a submersible on board is very appealing. With some of the latest models on the market able to reach staggering depths, submersibles can dive into remote parts of the ocean and get up close and personal with marine life that was once inaccessible. The idea of having a submersible on board is no doubt also an exciting one for many captains and crew, but it does come with concerns about complex operations and maintenance procedures.

The submersible experience 

On board the 55m Damen yacht support vessel Axis is a Triton 3300/3 submersible that can reach depths of 1,000 metres with two passengers and a pilot. Captain Les Annan says just going underwater in the submersible is an amazing first-time experience for most people. “Once you go below 35 metres [the safe scuba-diving limit], you are the first human to see whatever you see,” he adds. “Taking the sub to dive sites is very interesting as well as you can see so much aquatic life and geological sculptures. Being in the sub is more comfortable than scuba diving as you are dry and have communications [with the surface], with an enhanced peripheral view that you don’t get through a dive mask.” 

Captain Jan Rautawaara has worked on superyachts for most of his career and has spent the past couple of years aboard the luxury cruise ship Crystal Esprit , which has a U-Boat Worx C-Explorer 3 submarine on board. He agrees that the submersible experience is unparalleled for guests. “From an experience point of view, it is unique and guests always find it very exciting,” says Rautawaara. “Guests will normally have high expectations about what they are going to see, but you never really know what you will find during a dive. To show them something special, it is best to dive deeper to depths of around 100 metres, where you can see things that can’t be seen [when] scuba diving.” 

With regards to visibility and how much you are going to see, Annan says this can vary a lot, just like scuba diving, and depends to what depth you are diving. “At depths deeper than 250 metres, natural sunlight does not penetrate the water, so it’s pitch-black,” he says. “The submersible has strong lights so that you can see for a distance of about 20 metres depending on the visibility. The lights highlight all the colours so it is very magical and colourful down there. When you go deeper than 500 metres, the sea life is even more interesting and different from what you find in shallow water. It truly is an outer worldly experience.”

Destinations and permission

The main challenge with submersible operations comes down to stringent local laws in certain destinations. “If you want to use the submersible, you have to have a permit from the local authorities to dive and some countries can be very strict due to a lack of awareness of what a submersible actually is,” advises Rautawaara. “Even though scuba-diving companies can go pretty much anywhere, the authorities sometimes only give an assigned area in which the submersible can be used and often these sites don’t show much of interest. For example, we couldn’t get a permit in Greece and only managed to get permits for three sites in Croatia. In the Caribbean, we couldn’t get a permit for the British Virgin Islands; however, we did for Saba, St Barths and St Kitts and Nevis.”

In Annan’s experience, while not all countries will allow yachts to just show up with a submersible and dive, working with a local agent and allowing some preparation time will usually result in permission being granted. One particular aspiration for him is to go with Axis to Truk Lagoon in Micronesia where there are many untouched Japanese wrecks from the Second World War that are too deep for scuba diving.

Set-up and launch considerations

“While not necessary, the ideal set-up would be a hanger or garage for the submersible so that it can be kept inside when not in use, protected from the elements and [where it is] easy to maintain,” says Rautawaara. “A crane capable of lifting the sub into the water by the vessel’s side is also needed. Once the submersible is in the water, the pilot enters from a tender, the submersible is disconnected from the mother ship, guests are brought on board and the dive can begin. We usually operate close to the mother ship, no more than a mile away. Furthermore, the submersible pilot is also in constant communication via an underwater radio transmitter, with our tender acting as the surface safety guard boat. Safety is obviously the highest priority at all times and even the passengers get a thorough safety briefing before going on board the sub.”

On board Axis , submersible launches can be made over a sea wall. “This means when we are in deep water, we can use the Damen dynamic positioning on board to allow us to hold position after the launch of the submarine directly over the desired area of interest with no commute from shallower anchorages, allowing more ‘action time’ on the dive,” explains Annan. While Axis does not have an A-frame and gets along fine without it, Annan recommends it for a boat going around the world because it allows the launch and recovery of the submersible in higher seas.

“We are very lucky to have such a capable boat as the Damen yacht-support vessel to work from and great owners [who] give us all the tools we need to make it enjoyable for them and their guests,” continues Annan. “Damen has an amazing worldwide support system for the yacht, so going anywhere in the world is not a worry on Axis . Damen fitted us with a 19,000-kilo crane that easily picks up the 8,000-kilo submersible and all of the other toys on deck. An average dive lasts two to three hours and reaches depths of 200 to 300 metres. Before a dive begins, a short Triton safety video is played, just like on an airplane, and the pilot gives the passengers a short briefing before going down.” 

There is some misunderstanding that submersibles are complex pieces of equipment to set up. For the submersible on board Axis , the sub pilot needs to be certified by Triton Submarines and approved by the insurance company or Triton will supply a sub pilot when needed anywhere in the world. “I went to its school for two weeks and then did over 20 dives with an instructor and [had] a verbal test from a group of instructors,” says Annan. “In my case it was easy to learn as I am a master scuba-diving instructor with over 6,000 dives. I also do all the service on the sub as well as I have a Y1 engineer ticket and the sub is very easy to work on and maintain. I can now train new pilots and when I think they are ready Triton can come out and test them.”

Rautawaara is also trained as a pilot for the U-Boat Worx submersible on board Crystal Esprit . “The pilot licence consists of about three weeks of training and teaches you about all the systems on your specific model of submersible,” he explains. “You then have to pass a theory and practical assessment which goes through all emergency scenarios. With regards to maintenance, there is not much that the yacht’s crew are able to do as the manufacturer has a very good system and logging process to keep on top of the maintenance requirements. For any technical issues, they will send one of their own technicians to the vessel. In addition, our submersible is also inspected annually by a classification society just like any other vessel.”

The crew on board Axis are all well trained in lifting heavy items on deck and in surface operations for the submersible as well. Whenever the submersible is in use, a tender is shadowing it on the surface, supplying a GPS signal and communications with the sub which orally checks in every 15 minutes to ensure communication at all times.

The submersible market has been stigmatised to some extent in the superyacht industry because of unfounded concerns about complex and dangerous operations. However, the industry is coming to realise just how amazing the submersible experience can be, as described by the captains above, as well as just how straightforward the operational aspect actually is.

The Latest Trend on Yachts? Submersibles.

Only boats at least 120 feet long can hold a sub, which typically costs between $2 million to $7 million. Manufacturers of the deep-sea vessels say many of their clients are wealthy enthusiasts.

By Ephrat Livni ,  Michael J. de la Merced and Sarah Kessler

Charles Kohnen, co-founder of the submersible manufacturer SEAmagine Hydrospace, estimates that there are 200 manned vessels worldwide. Some are used by scientific institutions, others for tourism. But a growing number belong to a select group of yacht owners.

While a ticket aboard a submersible tour, like the one that ended in tragedy this year en route to the Titanic shipwreck, is too pricey for most people, owning a submersible requires another level of wealth and boating infrastructure.

Only sufficiently large yachts — at least 120 feet — can hold a sub, which typically costs between $2 million to $7 million (not including the cost of a crane to lower the sub, the speedboat needed to board, and services like mapmaking and guides that can run about $15,000 per day).

“It’s not like a fancy car,” Kohnen said. “It’s more like a $5 million spacecraft.”

Just as having a helicopter and launchpad on a yacht was hot in the 1980s, Kohnen said, getting a personable submersible is increasingly a thing for the wealthy.

Ofer Ketter, whose company, SubMerge, caters to personal sub owners, sees a similar trend. “You have a mega-yacht, a super yacht — a submersible has become the next thing to have,” he said.

Deep-sea explorations have a growing fan base among the elite. The filmmaker James Cameron and the billionaire investor Ray Dalio have both donated vessels to the Woods Hole Oceanographic Institution and invested in the submersible manufacturer Triton Submarines . Dalio said it was about discovery. “The ocean is the greatest resource we have,” he said. “It’s twice the size of all continents combined — and underexplored.”

Some submersible owners lend out their vessels for documentaries and scientific research, while others are in search of never-before-seen species or want to explore shipwrecks. And there is a kind of mixed-use model that is versatile for everything from an underwater wedding to cocktails on the reef, dinner or a poker game, said Craig Barnett, Triton’s director of sales and marketing.

The personal submersibles industry has grown with the size of yachts. When SEAmagine started in 1995, mostly robots were used for deep-sea scientific work because lowering submersibles into the ocean with people inside was unwieldy, Kohnen said. The company built a model that could be boarded from the water, and this relaunched an era of manned submersibles for science and tourism. Around 2005, SEAmagine got its first yacht commission — and competition. Another submersible manufacturer, U-Boat Worx, started operations in the Netherlands, and Triton soon followed. Yachts were becoming bigger, but, Kohnen said, people were also starting to value experience-seeking over luxury.

Making “the moment.” Where to dive and how long an expedition lasts depends, but an adventure can take months of planning to scout, map and set up. SubMerge has coordinated five expeditions with three different private clients this year, Ketter said, and the company works with about six luxury travel firms, including submersible manufacturers.

A typical day “in a good spot” usually involves a few dives that last about an hour or two, with breaks for meals, Kohnen said. “Even after a thousand dives, it never stops being exciting.”

What about the implosion of the Titan? The fatal OceanGate tour shined a harsh spotlight on deep-sea adventure. But Kohnen said the craft involved was an “outlier” that was not built to specifications and had been a cause of concern in the submersible community for years.

Ketter said that his company had not had any cancellations since the accident. Triton likewise said that it had no cancellations, that it was building five submersibles and experiencing “remarkable demand” from private owners and tourism companies.

Although private submersibles are gaining momentum, Barnett said, the number of scientific institutions using them was “regrettably low.” Dalio said he thought filming the ocean from private craft would spur more investment and exploration. “It’s very underfunded, but it’s picking up,” he said. — Ephrat Livni

IN CASE YOU MISSED IT

The Fed could pause interest-rate rises next month as inflation cools. Consumer prices rose moderately in July , according to Consumer Price Index data released this week, and consumers expect inflation to slow over the next year , a closely watched University of Michigan survey showed. The wild card is volatile food and fuel prices, which could add to inflationary pressures.

Goldman Sachs’s longtime chief of staff steps aside. DealBook reported that John Rogers , the bank’s longtime chief of staff, would start handing over some of his responsibilities to Russell Horwitz, a former deputy. The shake-up occurs as Goldman’s C.E.O., David Solomon, conducts an overhaul of the bank, which has seen prominent executives leave.

Disney vows to stem streaming losses and doesn’t rule out selling its TV businesses. The entertainment giant’s C.E.O., Bob Iger, said subscription-price increases for Disney+ and Hulu would go into effect in the fall. And, like Netflix, it will crack down on password sharing . Wall Street is getting impatient as Disney’s streaming losses have ballooned to more than $11 billion since 2019.

Zoom’s A.I. data policy sets off a backlash. The popular videoconferencing platform issued a clarification this week that it would seek customers’ consent before using their audio, video or chat data to train artificial intelligence models. Digital rights’ advocates, however, worry that may not be enough to protect unsuspecting Zoom users as privacy concerns multiply alongside the explosion in popularity of A.I. tools like the ChatGPT and Bard chatbots.

A Kennedy bets on start-ups that serve the disabled

The Kennedy family has for decades made advocacy for the disabled one of its signature causes, from Senator Ted Kennedy sponsoring the Americans With Disabilities Act to Eunice Kennedy Shriver founding the Special Olympics.

Now, a scion of the political dynasty, Christopher McKelvy, has teamed up with Judd Olanoff, a former JPMorgan Chase banker, to approach disabilities in a new way: by starting a venture capital firm focused on the community.

Meet K. Ventures. McKelvy — a grandson of Patricia Kennedy Lawford and a former tech executive — and Olanoff initially worked together on public policy advocacy for people with disabilities and their families at the Joseph P. Kennedy Jr. Foundation. (McKelvy is a trustee at the foundation.)

They realized that the start-up sector offered both new services for the disabled and viable business models that could scale because of developments like Medicaid reimbursements. McKelvy and Olanoff left the foundation last year to start their firm. Its backers include Brian Jacobs, a longtime investor who runs Moai Capital, who told DealBook that the founders’ connections “are definitely unique and valuable.”

“My family’s hope,” McKelvy told DealBook, “is that K Ventures will be the next chapter” of our work on behalf of the disabled.

The firm is a bet on the growing market for disability services. The Centers for Disease Control and Prevention estimates that up to 27 percent of the country’s population has some kind of disability. The agency also found in 2020 that one in 36 children has been diagnosed with autism, up from one in 44 in 2018, thanks to better recognition of symptoms.

Olanoff said big companies were also starting to invest in providing disability services and benefits, presenting an opportunity for start-ups.

K. Ventures has made three investments, including Juno, which provides cash benefits to parents if their children become severely injured or disabled; Juniper, which automates billing for behavioral health services providers; and NeuroNav, which helps adults with developmental disabilities in California devise their own customized help services.

Major investment firms have also started to take notice of the opportunity: Andreessen Horowitz and Y Combinator have backed Juniper, while Pear VC has invested in NeuroNav.

McKelvy and Olanoff are using the Kennedy name and resources, including by bringing in advice and networking opportunities from relatives like Tim Shriver, the chairman of the Special Olympics, and Patrick Kennedy, the former congressman. For the past two years, it has also hosted a forum for disability start-ups at the Kennedy compound in Massachusetts.

Shriver believes disability advocacy needs philanthropy, but also businesses with sustainable and profitable operating models. When his team heard about K Ventures, he said, “we thought, bingo, that’s the missing piece.”

The reporting behind Netflix’s ‘Painkiller’

The Supreme Court temporarily blocked a bankruptcy deal for the Sackler family’s Purdue Pharma, the maker of OxyContin, on Thursday. The agreement would have capped the liability of the Sacklers at $6 billion and protected the family from any more civil lawsuits connected to the opioid epidemic. But the ruling will likely delay payments to the thousands of people who sued the Sacklers and Purdue.

In 2003, Barry Meier published “Pain Killer,” a book about the illegal methods and distorted science that Purdue had used to promote OxyContin. This week, Netflix released a fictionalized series based on the book starring Matthew Broderick as Richard Sackler, the former president of the company, who led the push to develop the drug and make it a routine treatment for pain.

DealBook spoke with Meier, a former reporter at The New York Times, about what had changed — and had not — since he first began investigating the role companies played in the crisis. This interview has been edited and condensed for clarity.

Why does the story remain so relevant two decades after the book was published?

It’s remarkable, and sad that it took as long as it did for the book to reach this big audience. But there’s hardly a person in this country who hasn’t been affected in some way. It’s 20 years from when it was published, and during that time more than a quarter of a million people died of overdoses from prescription opioids like OxyContin.

You said the book was a “total flop” when it was published. Was there an inflection point when people started paying more attention to the story of Purdue Pharma?

It started about 2017, 2018, when there was this new wave of lawsuits brought against not only Purdue, but individually against members of the Sackler family. That was a real turning point, because we began to see internal documents that were written by Richard Sackler. And, subsequent to that, the photographer Nan Goldin began her campaign for museums to take the Sackler name down from their walls, which turned out to be a remarkably successful political and cultural campaign.

Has anything changed in the relationship between the pharmaceutical industry and Washington?

I would hope that the Food and Drug Administration will never again make a decision as catastrophic as it did when it allowed Purdue to claim that this incredibly powerful and potentially addictive drug might be safer than competing drugs without even a shred of evidence.

But you can never be sure. I have seen numerous instances where a medical product that was valuable for a limited pool of patients has run amok because its manufacturer decided that in order to make billions of dollars, it was going to have to promote it to as many patients as possible — patients for whom the benefits of the drug began to be outweighed by its substantial risks. This is not a pattern that’s unique to OxyContin.

Could that pattern be shut down?

Until we start seeing corporate executives marched off to prison for violating the trust that doctors and patients have put into them, nothing is going to change.

Everything you need to know about US Navy submarines

The silent service, “We come unseen.”

By Joshua Skovlund | Published Mar 20, 2024 10:23 AM EDT

• Military Life

The first recorded submarine attack in naval combat happened in 1776. An American submersible craft dubbed “Turtle” attempted to attach a time bomb to the British flagship called “Eagle,” which was a part of the Boston Harbor blockade. 

Though that early attempt failed, the desire to improve submersible technology led to today’s nuclear-powered submarines. The U.S. Navy just christened its latest Virginia class fast attack submarine, the USS Idaho, during a ceremony on Saturday, marking it as the 26th boat in its class to be christened . 

But, with recent budget cuts, the construction start date of the Navy’s latest class of submarines — the SSN(X) — is delayed until the early 2040s . With the replacement of the Virginia Class submarine being postponed for the third time, the current submarines will remain in active service. 

A brief history of submarines in warfare

Ever since the Turtle was used to try to breach the British blockade during the Revolutionary War, the U.S. Navy has continued to pursue submarine technology and its advancement. Submarines are a vital part of America’s defense, along with many other allied nations. 

The U.S. officially entered the underwater world of warfare after purchasing the USS Holland (SS-1) in 1900. It was commissioned on Oct. 12, 1900. John Holland designed the USS Holland, which was used for experimental purposes during its 10-year career.

When World War I kicked off, the threat of submarines existed, but it was not prevalent due to the early stages of developing submarine manufacturing and technology. At the time, the Navy had 11 different classes of submarines that used a combination of diesel-electric propulsion systems. 

The diesel-electric submarines were a step up from the previous steam-powered submarines, though the British Royal Navy’s K-class submarines used in WWI were steam-powered. Submarines played a minor part in WWI’s overall warfare.  

That was until World War II kicked off with the Nazis unleashing their feared U-boats. They implemented their submarines on merchant lane traffic and American ships. A Japanese submarine launched an attack on Fort Stevens, Oregon, in 1942 . The U.S. Navy moved to update its submarines to take on the lethal threat presented by the Axis powers.

They accomplished their goal as evidenced by the damage done to Japan by American submarines , which sank 540,192 tons of Japanese naval vessels and 4,779,902 tons of merchant shipping during the war — 54.6% of all Japanese vessel losses.

But after WWII ended, the Cold War quickly followed, creating an arms race with the constant threat of nuclear warfare that lasted from 1947 to 1991. That’s when the nuclear triad was established. It’s a military-force structure comprising unique air, land, and sea nuclear missile launch capabilities. 

That’s what the first-ever nuclear-powered submarine, the USS Nautilus IV (SSN-571), was built for. It was commissioned on Sept. 30, 1954, and went on to be the first submarine and crew to cross the North Pole underneath the Arctic polar ice pack. 

Since the Nautilus first hit the water, submarine advancements have enabled the Navy to launch personnel and various missiles and torpedos without ever coming to the surface.

Different types of submarines active in the Navy

The Navy has nuclear-powered ballistic missile submarines (SSBNs), nuclear-powered cruise missile and special operations forces submarines (SSGNs), and nuclear-powered attack submarines (SSNs). 

Virginia, Los Angeles, and Seawolf Class submarines are all SSNs. Ohio and Columbia Class submarines are SSBNs. There is only one class of SSGNs, the Ohio Class. Each submarine class has a unique mission tailored to each boat’s capabilities. 

Attack submarines can hunt down and destroy enemy submarines and surface ships, as depicted in the 1990 blockbuster The Hunt for Red October . They can launch the Navy’s formidable Tomahawk cruise missiles or even special operations teams. 

Submarines have clandestine capabilities and missions, too. They can conduct intelligence, surveillance, and reconnaissance (ISR) missions, support naval battle groups underway, and conduct mine warfare.

Attack submarines (SSN)

The SSN(X) is the future of attack submarines , meant to replace the Virginia Class with the most up-to-date technology. However, with the project delayed and no official date established, it will be a while before anyone sees it in action. 

The Navy has 22 commissioned Virginia class submarines, also known as SSN 774, with several more being built. These submarines have the latest upgrades, and their overall design allows easier updates on weapons systems, optics, etc. This helps them stay relevant instead of decommissioning the entire submarine when an update or new capability is introduced. 

Virginia-class submarines can transport several special operations personnel and their gear for extended operations. The crew has visible and infrared digital cameras on telescoping arms, enabling them to see in various environments and weather. The submarines can also operate in littoral and coastal areas of the ocean. 

Updates to the Virginia class submarine include a water-backed Large Aperture Bow, which provides enhanced passive detection capabilities. The 12 individual vertical launch system tubes are replaced with two 87-inch Virginia Payload Tubes. 

Each tube can launch six Tomahawk cruise missiles using Multiple All-up Round Canisters; this makes it more capable of different payloads due to the larger diameter tubes. 

The Virginia class is replacing the Los Angeles class submarine (SSN 688), though the Navy still refers to this class of fast-attack nuclear submarine as “the backbone of the submarine force.” 25 Los Angeles class submarines are currently in commission. Each one is armed with 12 Vertical Launch System tubes for firing Tomahawk cruise missiles. 

They have 25 torpedo tube-launched weapons, which allows Tomahawk missiles to be launched horizontally instead of vertically. But, as Virginia class submarines are commissioned, more Los Angeles class submarines are decommissioned. 

The last class of attack submarines is the Seawolf class, of which the Navy has three. This fast, quiet, and extensively armed submarine has some of the best sensors available. The Seawolf class has eight torpedo tubes and a maximum capacity of 50 weapons in its torpedo room. It’s larger, quieter, and faster than the Los Angeles class submarines. 

However, not all Seawolf class submarines are the same. The USS Jimmy Carter (SSN 23), the third in its class, has a 100-foot hull extension. The Navy calls the addition the multi-mission platform, which allows the submarine to have “additional payloads to accommodate advanced technology used to carry out classified research and development and enhance warfighting capabilities.” 

Fleet Ballistic Missile Submarines (SSBN)

Nicknamed “boomers,” SSBNs are Ohio-class submarines designed as an undetectable launch platform for submarine-launched ballistic missiles. They are considered one of the stealthiest submarines capable of “precise delivery of nuclear warheads.”

There are 14 Ohio-class SSBNs , each carrying a maximum of 20 missiles, including the Trident II D5 missile, which has an increased range and accuracy compared to its predecessor, the Trident I C4 missile. SSBNs can go on extended deterrent patrols and have three large-diameter logistics hatches that allow speedy resupply, updates, and maintenance, which increases operational availability. 

According to the Navy, SSBNs spend an average of 77 days at sea, with a 35-day in-port for maintenance following each patrol. These submarines are a key component of the nuclear triad that acts as a deterrent to would-be enactors of nuclear conflict. 

The Columbia Class SSBN is the largest, most capable, and most advanced submarine in the fleet—but it’s not yet ready for deployment. The original target for the first commissioned Columbia Class submarine was FY2027, on par with the schedule of the US Strategic Command’s requirements. 

However, worker shortages and budget cuts have caused delays in building the first Columbia class SSBN, so there’s no definite date for the first commissioning ceremony. 

Guided Missile Submarines (SSGN)

The 1994 Nuclear Posture Review required 14 of the Navy’s 18 SSBNs to meet the nation’s strategic force needs. So, the Navy decided to transform four Ohio-Class SSBNs into conventional land attack and special operations forces platforms. This conversion of the four submarines was completed within five years. 

The USS Ohio (SSGN 726) was the first completed conversion in December 2005 and later deployed in 2007. The USS Florida (SSGN 728), USS Michigan (SSGN 727), and the USS Georgia (SSGN 729) were all mission-ready by 2007. 

All four SSGNs make up half of the Navy’s submarine fleet vertical launch payload capacity. Each SSGN can carry up to 154 Tomahawk cruise missiles. They can carry up to 66 special operations personnel, and the missile tubes can carry stowage canisters for their equipment and food, allowing extended deployment.

The SSGN build has ample room for the added personnel, which also contributes to extended deployments. The forwardmost missile tubes are actually lock-out chambers that allow for clandestine infiltration and exfiltration of operators. 

These submarines serve a dual purpose of special operations and guided missile munitions — a lethal combination for any naval warfare scenario.

General Dynamics Electric Boat Secures $145M Navy Contract Modification for Submarine Engineering Support

• March 22, 2024
• Contract Awards , News

A General Dynamics (NYSE: GD) subsidiary will continue to help the U.S. Navy design and provide engineering support for operational strategic and attack submarines under a potential $145 million contract modification .

The award also extends technical, design agent and planning yard support services for the service branch, the Department of Defense said Thursday.

General Dynamics Electric Boat will perform the majority of contract work in Groton, Connecticut, and the remaining 30 percent will occur in Georgia, Washington, Hawaii and Rhode Island through September 2024.

Naval Sea Systems Command will obligate funds using the Navy’s other procurement funds for fiscal years 2023 and 2024.

In July 2019, Electric Boat secured a potential $1.04 billion contract to provide the Navy with submarine-related drawings, logistics technical data, configuration management, design change documentation and other support services.

Navy to Christen Submarine Idaho

The Navy will christen its newest Virginia-class attack submarine, the future USS Idaho (SSN 799), during a 10 a.m. EDT ceremony March 16, at General Dynamics Electric Boat, in Groton, Connecticut.    The Honorable Nickolas H. Guertin, Assistant Secretary of the Navy (ASN) for Research, Development, and Acquisition (RDA), will deliver the ceremony's principal address. Senior representatives from the Navy, the shipbuilders, Congress, and the state of Idaho are also expected to speak.

In a twist on the time-honored Navy tradition of breaking a bottle of sparkling wine across the bow, the Submarine's Sponsor, Ms. Teresa Stackley, will christen the boat with water she has collected from several lakes in Idaho. Stackley is the daughter of a Navy Sailor and is the spouse of the Honorable Sean Stackley, a former Naval officer who served as ASN (RDA) from 2008 to 2017.

The submarine, which began construction in 2017, will be the 26th Virginia-class fast attack submarine and the fifth U.S. Navy ship to be christened with the name Idaho. The last ship named Idaho was battleship BB 42, commissioned in 1919. 

Though landlocked, the state of Idaho prides itself in its rich Naval history and continuing contributions to the fleet. The Navy's Acoustic Research Detachment on Lake Pend Oreille, Idaho's largest and deepest body of water, is a state-of-the-art facility that supports research, development, testing, and evaluation of submarine acoustic stealth technology and propulsor design. Lake Pend Oreille is a critical body of water to the U.S. Submarine Force.

Virginia-class submarines are built to operate in the world's littoral and deep waters while conducting anti-submarine warfare; anti-surface ship warfare; strike warfare; special operations forces support; intelligence, surveillance and reconnaissance; irregular warfare; and mine warfare missions. This next-generation attack submarine provides the Navy with the capabilities required to maintain the nation's undersea superiority well into the 21st century.   Media may direct queries to the Navy Office of Information at (703) 697-5342.

100-year mystery is finally solved after sunken WWI U-boat and tanker are found

Divers have found the final resting place of a World War One German U-boat which sunk in 1917 .

The UC-18 vessel was lost after a battle with a secret Royal Navy ship called the Lady Olive, which also sunk in the English Channel, on February 19 1917.

Divers have spent the last four years trying to find the exact location of both vessels.

The fate of the sub had been left unknown for almost 100 years because no wreckage had ever been found until now.

The case is thought to be the only one in history where a sub and the vessel it was attacking sank each other.

All 28 crew members on the German sub were killed, but British troops escaped with no injuries, and many were rescued off the French coast.

The find has now been filmed for a BBC documentary and underwater filmmaker Karl Taylor said he was ‘elated’ at the idea.

The documentary called The Hunt for Lady Olive and the German Submarine will air on the BBC in June.

He said: ‘Finding a wreck of this historical significance is a once in a lifetime discovery.

‘It’s been a long and technically challenging project but to be able to set the historical records straight on the details of the battle and the locations of the wrecks is fantastic.’

After extensive research around three possible target areas southwest of Guernsey, the sub was eventually found at a depth of more than 230ft.

They worked with Guernsey Press Picture Editor Peter Frankland to identify the wreck.

Karl said: ‘The organisation of the dives has been extremely difficult due to the amount of crew and equipment required, the location of the wrecks and the depth of water they’re in.

‘We were limited to diving during periods of slack water which only occur during small neap tides.

‘These had to be coupled with extremely calm sea conditions and good visibility to give us the best chance of completing these technically complicated dives safely.

‘Working so far offshore meant that we had to be especially vigilant when planning our dives as any help, should it be needed, was at least two hours away.’

The original battle took place eight miles off the coast of Jersey, but the sunken vessels have been found 40 miles further west.

The findings have now been passed over to French and German officials and the location is closed to divers because it is now a designated war grave.

The German War Graves Commission has expressed their grateful thanks to the team in locating the wreck.

They are making plans for a German Naval vessel to be deployed to the site to take part in a wreath laying ceremony this summer.
