A company has unveiled a new high-tech craft designed to carry passengers into the deep ocean in what’s being billed as the world’s fastest ‘underwater supercar’ — for those with the budget to match.
Submersible maker U-Boat Worx has presented its new ‘Super Sub’ and highlighted its headline performance figure. In underwater terms, it’s quick: the vehicle is said to top out at about 10mph (nine knots), which is roughly half the speed of a military submarine.
The company says the three-person sub can travel down to 300 meters, offering a more social, comfort-focused alternative to extreme solo dives such as James Cameron’s well-known $10 million one-person submarine, used during his 2012 Mariana Trench expedition.
It also comes in at a price that, while still eye-watering, is positioned as comparatively attainable for the superyacht crowd. U-Boat Worx lists the ‘Super Sub’ at $5.75 million — about the going rate for a Bugatti Divo — aimed at owners looking to extend their time on the water into the world beneath it.
Beyond the cost, the major differentiator is the experience on board. The craft is designed to make deep-ocean exploration feel less like a cramped mission and more like a premium excursion for its occupants.
According to the company, it can descend and steer at 45-degree angles, pairing that agility with a relatively high top speed and an operational range of 10 nautical miles. The intended “safe exploring depth” is up to 300 meters below the surface.
U-Boat Worx says it engineered the system for a ‘flight-like’ sensation beneath the water, using hydronamic lift to smooth out the ride during descents approaching 1,000 feet.
That approach is meant to give pilots more precise handling while exploring deep-water environments — with the added convenience of returning to the mothership, such as a superyacht, at the end of the trip.
In the shadow of 2023’s OceanGate Titan tragedy — which resulted in the deaths of four passengers and the company’s CEO — some would-be adventurers may be more cautious about private deep-sea travel. U-Boat Worx, however, is emphasizing safety systems and layers of redundancy as core parts of the design.
The ‘Super Sub’ is expected to be offered to high-net-worth buyers following a round of sea trials off Curaçao, near the northern coast of Venezuela. Engineers reportedly evaluated critical systems before the craft is made commercially available.
Those tests covered safety functions and the aircraft-style controls, as well as propulsion performance and other technical features intended to protect passengers during deep dives.
U-Boat Worx also says the craft includes onboard sonar to map what’s ahead and help adjust course to avoid impacts, along with additional redundancies intended to reduce the risk of failures seen in other ventures.
Among the key claims: up to 96 hours of onboard life support, plus an automated depth-monitoring system designed to prevent the ‘underwater supercar’ from dropping into pressure levels associated with far deeper water.
With trials completed, U-Boat Worx says it expects to hand over its first finished model to an owner within the coming weeks.
