Regular old fission power and ion engines.
- dogma1138 9y agoIon thrusters will not produce enough thrust to move something that big within a single lifetime. Fission will in essence be a steam power plant on that ship since RTGs do not provide sufficient power. Ion thrusters still need fuel, so you need to store gas, to move something that big it would be one heck of a gas tank, and which point thermal nuclear propulsion might be a better choice if you are mad enough to have a full nuclear reactor in space.
