Inside of Hovercraft, as seen in 'Traitor'.

The Spectrum Hovercraft is a highly versatile vehicle, which can be used on difficult terrain where other vehicles cannot. In a day-to-day basis, the hovercraft is used for patrol at the Spectrum training facilities such as Camp Sahara (in Northern Africa) and Koala Base (in Australia).

The Hovercraft is a four seater.

The Hovercraft is powered by fixed, pre-spin rotors and revolving rotor blades, which act as air-impellors to drive incoming air downwards to the air-cushion outlets to lift the hovercraft off the ground/water. The vehicle is mostly made of Fleetonium alloy, which makes it very strong and light. and of conventional sea vehicle materials. It  is blue and white in colouration.

The Hovercraft uses Thermionic Converters, which generate electrical energy by a heat exchanger system used to heat the air-fuel mixture, as a power source motors. It also runs on a special form of fuel from the Spectrum refinery at Bensheba as an alternative source of power.

It is unknown where the Hovercraft is constructed, but it could be presumed that it could be at Koala Base, Spectrum cadet centre and hovercraft base in Australia. Maintenance is performed at the various training facilities.
