The wave of the future: Even in the futuristic setting of Star Trek, some things would become 'outdated ½ such as the venerable U.S.S. Enterprise. The U.S.S. Excelsior, featured in this kit, was chosen as her successor. Marking decals: This kit includes a big decal sheet full of registry and pennant markings for the NX-2000 and NCC-2000 versions including NX strongback markings.
