The ISV's were the main transport of cargo and personnel to and from Pandora. The ISV's carry two Valkyrie Shuttles, used for the transportation. At 1,646 maters long, and the vehicle is gigantic. The engines actually pull the ship from the front, rather than push the ship like most space fairing ships. Cruising speed of ISVs is 70% lightspeed, and this is attained through two hybrid fusion/matter-antimatter engines.
