U-Boat Worx has completed trials of the Super Sub in the waters off Curaçao. The company confirms delivery to the first customer within the next few weeks. With 100 kilowatts of horizontal thrust and a top speed of nine knots, the vehicle is the fastest private submarine ever built. The tests focussed on propulsion, handling, control systems and safety architecture.
The submarine reaches a diving depth of 300 metres and has a range of ten nautical miles. The engineers carried out a series of demanding manoeuvres to validate its performance under real conditions. This demonstrated the ability to perform dynamic climbs and descents at angles of up to 45 degrees.
How to control the submarine
A high-precision sonar continuously scans the seabed and automatically adjusts the trajectory. When the maximum diving depth is reached, the system initiates a parabolic trajectory. The life support and control systems have a dual design and were tested under load throughout the test phase.
The controls are based on avionics standards and offer the pilot precise control over all axes of movement. The cockpit layout is ergonomically designed and enables intuitive operation. The pressurised acrylic cabin provides the pilot and passengers with a panoramic all-round view. This transparency creates an immersive connection to the underwater world without any visual restrictions.

Performance
The design of the Super Sub generates hydrodynamic lift while driving. The winged profile gives the vehicle stability and agility at the same time. The acceleration under water conveys a feeling of controlled flight in three dimensions. This characteristic distinguishes the vehicle from conventional submarines, which are primarily designed for slow locomotion. The speed makes it possible to explore large areas within a single dive. Reefs, steep walls and wrecks can be inspected with unrivalled freedom of movement. The combination of range and manoeuvrability opens up new possibilities for private underwater expeditions.
Deployment concept for the submarine
The submarine is designed for integration into yacht programmes or as a stand-alone exploration platform. Its speed makes long-range exploration within limited time frames practicable. Pilots can systematically search larger areas and hold a targeted position when discoveries are made. The manoeuvrability allows complex underwater formations to be viewed from different perspectives. While previous generations of private submarines focussed on access and dwell time, the Super Sub from U-Boat Worx focuses on active movement and speed.
Certification and delivery
The Super Sub has received full safety certification from DNV. This certification confirms compliance with all relevant standards for private submersibles. U-Boat Worx has built and delivered more than 60 submarines since the company was founded in 2005. The company supplies private customers, research organisations and the cruise industry. With the Super Sub, U-Boat Worx is expanding its range with a vehicle that defines speed as a key performance feature.
