Super Sub launch event 2026 | U - Boat Worx

Below 300 metres, there’s a version of the ocean that’s alive, fast, and largely unexplored.

The light changes. The pressure builds. Somewhere down there, a shark cuts through the blue at a speed no human-made craft has ever been able to follow. Until now.

The Super Sub was built to take you there. The fastest private submersible ever built. Nine knots. 100kW of thrust. Dives at 45 degrees. The only sub in the world that can keep pace with a shark.

But specs don’t capture what it feels like. Inside the dome, the ocean wraps around you. The hull banks. Hydrodynamic lift kicks in. You’re not descending anymore, you’re flying.

Twenty years ago, U-Boat Worx set out to make the ocean accessible. The Super Sub takes that mission somewhere new: not just down, but through.

Welcome to the era of underwater flight.
