Abstract : An electromagnetic railgun launcher and armature. The armature is made from superconducting material and is levitated between the rails of the launcher by the Meissner effect. The Meissner effect is created by cooling the armature and subjecting it to a magnetic field. The armature configuration has a closed loop topology and defines two planes - one plane coincides with the plane of the rails; the other plane is oblique to the first. The armature configuration, when placed between the rails receives an unbalanced Lorentz force which accelerates the armature.
