A launching system for space vehicles is proposed that is supported by fast-moving projectiles in an evacuated tube. In a worked example, payloads are propelled to a height of 50 km, comparable to the performance of a first-stage rocket. Recent progress in magnetic levitation makes such a system feasible with existing materials. An outline of the economics shows that it can be cost effective, although there are considerable engineering challenges.
