U-Boat Worx, the global leader in private, research, and cruise industry submersibles with more than 60 units in operation worldwide, is proud to share new imagery of the Super Sub, a revolutionary model that redefines underwater exploration.
– The flagship design of U-Boat Worx
– Innovative propulsion delivers a total of 100 kW and max speed 9 knots underwater
– Capable of exhilarating steep 45-degree climbs and impressive inclined underwater manoeuvres
– The panoramic ultra-clear acrylic hull delivers 360-degree views
This flagship design represents the pinnacle of U-Boat Worx’ engineering expertise and innovation. The Super Sub features a sleek droplet-shaped hull and advanced wing configurations, making it one of the most hydrodynamic submersibles ever crafted.
Its propulsion system, featuring four proprietary in-house-engineered thrusters, delivers a total of 100 kW and enables speeds of up to 9 knots underwater. This high-performance system allows for exhilarating steep 45-degree climbs and impressive inclined underwater manoeuvres, offering an experience unlike any other.
A first-class experience beneath the waves
The Super Sub elevates luxury to new depths, offering an experience akin to first-class travel compared to the business-class comfort of U-Boat Worx’s other models. Its interior is designed with meticulous attention to detail, combining cutting-edge technology with premium craftsmanship. Two passengers and a pilot enjoy spacious and ergonomic seating with a five-point harness system—not merely a feature for show but a vital safety measure for handling the sub’s high-speed manoeuvres.
The panoramic ultra-clear acrylic hull delivers 360-degree views, immersing passengers in the underwater world with unparalleled clarity and comfort.
Roy Heijdra, Marketing Manager at U-Boat Worx, shared: “The Super Sub is a marvel of engineering and luxury. It’s more than a submersible — it’s a first-class ticket to explore the ocean like never before, combining speed, safety, and sophistication in every dive.”
Crafted for excellence
The Super Sub was conceived through U-Boat Worx’ bespoke submarine programme, providing owners with the opportunity to have a submarine crafted beyond the standard range of submersibles. This tailored approach ensures the submersible embodies the unique tastes and aspirations of its owner.
Adventure, thrill, and beyond
While the Super Sub is perfect for adventure and thrill-seekers, U-Boat Worx also envisions broader applications for this advanced submersible. Its speed, agility, and manoeuvrability make it a strong candidate for use in search and rescue missions or other specialised operations, opening new possibilities in underwater exploration and response efforts.
