Nautilus (Verne) from seawater) is the craft's primary power source for propulsion and other services. "Nautilus" is double-hulled, and is further separated into water-tight compartments. Its top speed is . Its displacement is submerged. In Captain Nemo's own words: "Nautilus" uses floodable tanks in order to adjust buoyancy and so control its depth.

Jules Verne ATV docked to the ISS on 3 April 2008 to deliver its cargo. On 25 April 2008, "Jules Verne" used its thrusters to reboost the station into a higher orbit.
