Like all installations, the Spaceplane Hangar is upgradeable in Career mode. Finally, craft launched from the SPH will start from the Runway while the VAB launches from the Launch Pad. In bilateral mode, parts can be placed singly or with mirrored symmetry. Since version 0.90.0 this can be toggled. Also, the symmetry mode by default in the SPH is bilateral/mirrored the VAB's default is radial symmetry. The VAB is vertical in both regards, like a rocket.

The SPH workspace in general is horizontally oriented, like a plane or rover, as is it axis of symmetry when placing or moving parts. There are essential differences between the two. Also, while it keeps its own list of saved craft files and subassemblies of parts, these can all be cross-loaded between the VAB and SPH. The parts list is the same in both facilities. Like its counterpart the Vehicle Assembly Building (VAB), the Spaceplane Hangar is for craft construction.
