The simple rail gun and rail guns with normally conducting and superconducting augmentation are discussed using an energy approach. Ideal launch efficiencies neglecting Joule losses and assuming constant rail current during the launch are shown to be 50 percent for normally conducting systems, and up to 100 percent for systems with superconducting augmentation. Energy requirements of an actual system are compared with expected values for a system with superconducting augmentation. The situation of variable rail currents has also been discussed.
