Thunderbird 4 is a small but technologically advanced submarine. Built by Brains for underwater rescue missions, the vehicle can travel at a speed of 160 knots and dive to a depth of 36,000 feet. TB4's mechanical arms and high-powered torch enable it to clean up toxic waste and shipwrecks. Built-in hover jets allow Thunderbird 4 to travel over land when required.
