How It Works-Amazing Vehicles

Submarine wings Like an aircraft in reverse, these hydrodynamic ‘wings’ are designed to pull the sub downward.

Buoyant foam The sub’s buoyancy is provided by syntactic foam, made up of tiny microspheres of hollow glass set in epoxy.

Viewing dome Breaking with submersible tradition, this semicircular dome is made of synthetic quartz and offers a panoramic view of the deep.

Pressure hull The pilot lies on their stomach inside a cylindrical tube made of 13cm (5.1in)-thick carbon fi bre.

Thrusters Working in harmony with the wings, these thrusters allow the sub to cruise up to 10km (6.2mi) over the ocean fl oor.
