Life-cycle-cost including the development and production costs of future space transportation systems as RLV is evaluated by optimizing the objective functions. The results describe that the optimized vehicle has the potentialities to reduce the life-cycle-cost dramatically and to increase the number of flight, depending on the thrust level.
