A new “Super Sub” enters the submersible market

U-Boat Worx reveals the fastest addition yet to its already impressive fleet of models - the Super Sub.

Distinguished by a long tail and advanced wing design, the Super Sub is the most hydrodynamic sub on the market. A best-in class propulsion system with four powerful thrusters delivers a total of 60 kW allowing for steep 30-degree climbs and dives. The result is the smoothest and most exhilarating underwater experience, capable of diving to depths of 300 meters, all while maintaining an almost 360-degree view.

Conceived by an owner whose brief was to create a submarine capable of keeping up with large marine life, the Super Sub delivers an unprecedented eight knots underwater. That's two knots faster than the cruising speed of a bottlenose dolphin, and five knots faster than the average submersible.

The Super Sub is more than a ticket to an underwater theatre, it's a backstage VIP pass that immerses guests in the heart of the action.

With the first Super Sub model already sold and set to deliver in 2023 the sub is set to form a core part of the company's general range of submersibles; the Super Sub will eventually become a fully developed range of models.

Maximum manoeuvrability and speed

the Super Sub delivers an unprecedented 8 knots underwater. That's 1-2 knots faster than the top cruising speed of a bottlenose dolphin, and 5 knots faster than the average submersible. Glide behind a bale of sea turtles. Cruise alongside a shiver of sharks. Dive and turn with a school of dolphins or swoop through the undercurrent of a powerful barracuda. The Super Sub is more than a ticket to an underwater theatre, it's a backstage VIP pass that immerses guests in the heart of the action.

Unimpeded view

To experience the underwater world in the optimal way, one of U-Boat Worx' design priorities has always been the clearest view. To ensure this, our remarkably clear fully acrylic pressure hull has been positioned at the front of the submersible, providing an unobstructed view in every direction, unimpeded by ballast tanks, batteries and other components.

Movable trim weight

One of the innovative features of the Super Sub is the new movable trim weight system. When the pilot wants to make steep dives, a trim weight at the back of the submersible slides forward, displacing the center of gravity. The extremely powerful thrusters at the back of the Sub give that extra boost needed to make thrillingly fast descents.

Effortless control

The innovative SHARC controller makes sure both the movable trim weight system and hydrofoils operate in unison with the powerful truster systems to guarantee guests the most thrilling ride.


The innovative Hydrofoils on the back of the submarine allow the sub to direct the flow of the thrust in a more effective way. Making it possible to make sharp turns and banks in the Super Sub.
